Description

FIELD OF THE INVENTION

The present invention relates to medicine and, more particularly, to pharmacology, i.e., to methods for producing medicinal agents based on a composite comprising an oxidized glutathione composite and a platinum material, in particular cis-platin, that are intended to be used for preventing and treating various pathologic syndromes and diseases by way of differentiated influence on processes of metabolism, proliferation, differentiation and apoptosis of normal and transformed cells.

BACKGROUND OF THE INVENTION

Certain issues in modem pharmacological industry involve counteracting two medical-biological problems:

forming a resistance (tolerance and pharmacological efficacy decrease) to medicinal agents including cases due to activation of the MDR-genes system; and

forming of undesirable resorptive effects manifested, first of all, by alteration of the immunocompetent cell system and hemopoiesis; cardio-, hepato-, nephro- and neurotoxicity.

A typical cause for these problems is a wide administration of chemotherapeutic agents that can be quite effective, according to their physical-chemical properties, but can also be foreign to an organism at their very nature. Even genetic-engineering medicines, in spite of human genes (DNA) application as a matrix for multiplication, use single-celled organisms ( Escherichia coli , yeast cells) that bring in their own, and therefore, xenobiotic contribution into obtained drugs.

Theoretical and practical medicinal research are now paying greater attention to natural key metabolites, i.e., key factors (low molecular biochemical substances) that are naturally determined to trigger chain reactions for endogenous production and modification of many biologically active products for physiologically important and adequate processes. In some cases these biochemical substances function as “biochemical gyroscopes” assigned to restoring the balance of altered equilibrium of basic metabolic processes, for example, anabolism and catabolism or proliferation and differentiation. Alteration of the balance of these vital mechanisms can lead to cell destruction (cytolytic syndrome) or their transformation into malignant ones, i.e., cancer. As a rule, the key regulatory metabolites, i.e., “cellular hormones”, are peptide origin factors (usually not larger than 3-20 amino acids). Obtaining synthetic analogues (biochemical substances) and, therefore, drugs with predetermined properties is a desired goal because these drugs are optimal as metabolic therapy instruments and, in fact, are not foreign to the organism.

Ideal peptide structures that can function as these synthetic analogues include sulphur-containing peptides and derivatives thereof, due to the presence of a thiol group. In particular, biological effects of the tripeptide “reduced glutathione” (γ-glutamyl-cysteinyl-glycine; hereinafter—GSH) are known to be researched extensively. The glutathione tripeptide dimer, oxidized glutathione (γ-glutamyl-cysteinyl-glycine; hereinafter—GSSG), where two molecules of the tripeptide with the aforementioned formula are linked via a covalent bond between cysteine residues, is also well known.

Administration of the exogenous synthetic GSSG analogue is known to induce cytokine and hemopoietic factor synthesis during in vitro experiments, and to provide the setting of the cytokine profile to normal values in conditions of cyclophosphamide and radiation immunodepression models (in vivo experiments) along with the immunity and hemopoietic system restoration (International application WO 97/21444, MKI A61κ38/02, published Jun. 19, 1997).

In their turn, the exogenous GSSG drug forms applied to severe immunodeficient conditions and suppressed bone marrow hemopoiesis containing chemical examples relating to clinical Examples in the International Application on AIDS patients, patients with oncopathology, aplastic anemia,and other conditions at treatment courses of different durations, can provide a curative effect in restoring the organism immune status (including antitumor immunity indices), immunogenesis and hemopoietic functional activity (International application WO 97/21444, MKI A61κ38/02, published Jun. 19, 1997).

Previously, the thiol class of biologically active substance had applications aimed to provide GSH at increased levels, i.e., to obtain antioxidant effects. In addition, pharmacological activity was observed, namely, for the pro-oxidant effect gaining and forming of a new intracellular redox-balance by introduction of GSSG that possesses pro-oxidant potential into an organism. This is the only known case of triggered redox-sensitive mechanisms for immunologically significant genes, activation of the cellular thiol metabolism, and therefore, beneficial pharmacological properties were provided including systemic cell-protective effects and immunity state regulation depending on initial cell status: immunodeficiency, i.e., hyporeactivity, immunoautoaggression, i.e., hyperreactivity.

International Application WO 97/21444, MKI A61κ38/02, published Jun. 19, 1997, is directed to gain a set of technical and pharmaceutically acceptable solutions effective for the prevention of the GSSG reduction into GSH and, thus, for extending the lifetime of GSSG as the oxidized form in biological media. Attainment of the biological-pharmacological effects of the glutathione oxidized form is proven by the biomedical investigation results obtained in the course of the complex and extensive preclinical and clinical studies program on synthetic GSSG analog effectiveness. A strategy for extending the lifetime of oxidized GSSG includes providing: salts thereof, composite drugs including GSSG combinations with substances that prolong or enhance the effect of GSSG or salts thereof, or derivatives as a new composite, i.e., a mixture of oxidized GSSG and other materials. The pharmaceutically acceptable GSSG derivative in the form of the salts thereof, or combinations with extenders of the GSSG existence in the oxidized form, or GSSG combinations with enhancers/modifiers, i.e., all technical solutions stabilizing in the varying degree the GSSG molecule disulfide form were first demonstrated to be significantly more effective in inducing the cytokine and hemopoietic factor production in normal conditions and to a greater degree in pathologic ones.

GSSG derivative drug forms are characterized with a larger fraction of the GSSG stabilized in the disulfide form, with maximal pharmacokinetics in biological media. These forms manifested the following features:

a) Inducting production of a wider range of cytokine and hemopoietic factors that can determine the presence of largely modulating effects rather than only stimulating ones.

b) Reproduction of particular cytokine effects, for instance, IL-2.

The events developing in cells (tissues and, therefore, organs) after interaction with cytokines is well known. These events are conditioned by the universal cytokine influence on the main signal-transducing systems and, through the latter, on the cell genome determining regulating cytokine effects on proliferation, differentiation, and apoptosis.

Methods for obtaining the oxidized GSSG form from the reduced GSH precursor are well known. The labile mercapto-SH-groups of cysteine in GSH can be oxidized with such soft oxidizers as air oxygen (R. Douson, D. Elliot, W. Elliot, K. Jones. Biochemist's manual, Moscow, “Mir”, 1991; Tam J. P. et al., Int. J. Pept. Prot. Res., Vol. 29, p. 421-431, 1987; Ahmed A. K. et al., J. Biol. Chem. 250, p. 8477-8482, 1975). However, the reaction rate is rather low in this case and desired quantitative yields require very long periods of time (many days). Catalysis by heavy metals ions and, especially, by copper can be toxic, and can create significant problems for obtaining pure pharmaceutical medicines.

Another oxidation method involves more potent oxidizers such as, hydrogen peroxide, iodine, potassium ferrocyanide, etc. (Kamber B. et al., Helv. Chim. Acta., Vol. 63, p. 899-915, 1980; Hope D. B. et al., J. Biol. Chem., Vol. 237, p. 1563-1566, 1962). These reactions generally proceed much faster (dozens of minutes to several hours). A disadvantage, however, is a difficulty in controlling reaction conditions that can result in significant contamination of the product with oxidation products, e.g., derivatives of the corresponding acids. It is sometimes necessary to add additional, sometimes rather labor-consuming purification procedures, that can sharply appreciate the process.

Yet another oxidation method involves the use of gaseous substances (nitrogen oxides), sulfoxides and other compounds as oxidizers. These oxidizers, however, can be toxic. (William A. Kato et al., Chem. Pharm. Bull., vol. 34 (2), p. 486-495, 1986; A. Meister et al., Ann. Rev. Biochem., p. 711-718, 1983.)

All these methods do not necessarily improve the quantitative yield of the desired product compared to older methods, and at the same time, can provide additional problems regarding toxicity and safety, as in case of nitrogen oxides, or more difficult accessibility of the reagents and their high cost.

Another previously known method involves the use of hydrogen peroxide as an oxidizer (Amber B. et al., Helv. Chim. Acta., Vol. 63, p. 899-915, 1980). The process is performed in the water solution with pH about 8.0-8.5 using the hydrogen peroxide equivalent at the room temperature. The reaction time is about 1 hour and the product yield is 90%. The main impurities (up to 10%) are other oxidation products, which can be removed only by means of an expensive preparative HPLC separation that can sharply increase the drug cost.

SUMMARY OF THE INVENTION

The present invention involves the creation of new pharmaceutically acceptable compounds with predetermined properties based on GSSG, i.e., an oxidized glutathione-based compound having a stabilized disulfide bond. The present invention also provides a new method for obtaining the oxidized glutathione as a composite with the stabilized disulfide bond during the product synthesis. The method involves the production of the composite having the formula: bis-(γ-L-glutamyl)-L-cysteinyl-bis-glycine disodium salt with a platinum material such as cis-platin, i.e., cis-diamminedichloroplatinum, preferably in the mole ratio 3000:1, more preferably in a mole ratio of 1000:1.

According to the invention the composite is characterized as having a stabilized disulfide bond. Upon introduction into biological media, consequently, a longer drug half-life time is provided in the biological media in the disulfide form.

The general procedure of the present method for the composite production involves using the reduced glutathione for the oxidation reaction as a hydrogen peroxide oxidizer combined with a platinum material, in particular, cis-diamminedichloroplatinum, as a catalyst. The method allows using lesser amounts of hydrogen peroxide (for example, 0.9 of an equivalent), resulting in an elimination of the superoxidation products along with very high yield for GSSG (more than 98% by the HPLC data). Thus, the product obtained has high purity and does not require additional purification.

One aspect of the present invention provides a composite comprising an oxidized glutathione-based compound and a metal material in a ratio between about 3000:1 to about 1:1. The metal material comprises a metal selected from the group consisting of platinum and palladium.

Another aspect of the invention provides a method for stabilizing a disulfide bond of an oxidized glutathione-based compound. The method comprises interacting the oxidized glutathione-based compound with a metal material. The metal material comprises a metal selected from the group consisting of platinum and palladium.

Another aspect of the present invention provides a method of stimulating endogenous production of cytokines and hemopoietic factors. The method comprises the steps of introducing to a mammalian body, in need of stimulation of cytokines or hemopoietic factors or both, an effective amount of a composite. The composite comprises an oxidized glutathione-based compound and a metal material in a ratio of between about 3000:1 to about 1:1. The metal material comprises a metal selected from the group consisting of platinum and palladium. The method is carried out for a period of time to stimulate the endogenous production to obtain a therapeutic effect.

Another aspect of the present invention provides a method for enhancing and prolonging the ability of an oxidized glutathione-based compound to stimulate endogenous production of cytokine and hemopoietic factors. The method involves the steps of interacting the oxidized glutathione-based compound with a metal material in a ratio of between about 3000:1 to about 1:1. The metal material comprises a metal selected from the group consisting of platinum and palladium.

Another aspect of the present invention provides a method for treating a subject having a disease. The method comprises administering to the subject in need of such treatment a composite comprising an oxidized glutathione-based compound and a metal material in a ratio of between about 3000:1 to about 1:1 in an amount effective to stimulate endogenous production of cytokines and/or hemopoietic factors or both to obtain the therapeutic effect. The metal compound has a metal selected from the group consisting of platinum and palladium.

DETAILED DESCRIPTION

The present invention discloses a number of oxidized glutathione-based compounds having a stabilized disulfide bond and in particular, a composite comprising the compound of this invention with a metal material. Methods for the preparation of a composite and for using the composite to treat a variety of diseases are also disclosed.

One aspect of the present invention provides a composite comprising an oxidized glutathione-based compound and a metal material. Generally, a “composite” can refer to a mixture of different chemical species. The “mixture” can be a physical mixture or a chemical mixture, i.e., having a chemical interaction involving either a chemical bond or an electrostatic interaction. In one embodiment, the mixture can be prepared by dissolving and/or suspending the different chemical species in a solution and precipitating out or filtering out a resulting solid. In another embodiment, the mixture can be a homogeneous solution comprising the different chemical species.

An “oxidized glutathione-based compound” refers to any compound having a basic dimer structure where each unit of the dimer comprises a glutamic acid group or salt or derivative bonded to a cysteine group or salt or derivative bonded to a glycine group or salt or derivative, and each unit is correspondingly bonded to each other by the cysteine sulfur atoms to form a sulfur-sulfur bond (disulfide bond). A “derivative” can be prepared by reacting at least one reactive group of the oxidized glutathione-based compound or precursor with another chemical species. An example of an oxidized glutathione-based compound is GSSG itself. Other examples are provided below.

In one embodiment, the oxidized glutathione-based compound has the general formula:

A, B, D, E, G and H can each be selected from the group consisting of an organic unit and salts of the organic unit. Preferably, the “organic unit” allows the glutathione-based compound to remain soluble in biological media and in addition, the organic unit should not impart toxicity to the oxidized glutathione-based compound in an applied dosage. It is understood that A, B, D, E, G and H can be the same or different. Preferably, groups A-H can each include a unit selected from the group consisting of amine groups, carboxyl groups, and amides. For example, A-H can represent amino acids or derivatives bonded via an amide bond. Alternatively, any two of A-H can be linked to each other by at least one covalent bond. Thus, A-H can be part of a cyclic structure.

In one embodiment, the composite comprises a large excess of the oxidized glutathione-based compound relative to the metal material, preferably in a ratio of between about 3000:1 and 1:1, more preferably in a ratio of between about 1000:1 and 1:1, more preferably in a ratio of between about 1000:1 and 10:1, even more preferably in a ratio of between about 1000:1 and 100:1. In another embodiment, the composite comprises equal amounts of the oxidized glutathione-based compound and the metal material, i.e., a ratio of about 1:1.

In one embodiment, the metal material comprises a metal selected from the group consisting of platinum and palladium. Preferably, the metal is platinum. Ideally, the metal material, in combination with the oxidized glutathione-based compound, renders the composite soluble in biological media. Small portions of the metal material can be insoluble, as long as the insoluble portion does not result in any toxic or hazardous effects to the biological system. A platinum material can be selected from the group consisting of a platinum salt, a coordination compound and an organometallic compound. Preferably, the platinum material is a platinum coordination compound such as cis-platin (cis-Pt(NH 3 ) 2 Cl 2 or cis-diamminedichloroplatinum—FIG. 3 ).

In one embodiment, the oxidized glutathione-based compound is oxidized glutathione itself (GSSG) and salts thereof, where both A and E are —CO 2 H, both B and D are —NH 2 and both G and H are —CO 2 M, M being a counterion. The counterion can be a proton, an organic-based ion such as tetralkyl-amononium, an alkaline metal, an alkaline earth metal, or a transition metal. It is understood that in aqueous media, any of A-H can comprise an ionized group, e.g., A and E can be —CO 2 —, and B and D can be —NH 2 and the ionized groups are neutralized by an appropriate counterion.

In a preferred embodiment, the present invention relates to the production of a new biologically active compound, i.e., a composite comprising an oxidized glutathione-based compound and cis-diamminedichloroplatinum. A convenient short-form notation will be used herein. For example, a composite comprising GSSG itself and cis-platin will be denoted as GSSG•Pt. Derivatives will be denoted by the newly appended chemical group, e.g., bis-[histidyl]-GSSG. While not wishing to be bound by any theory, a proposed structural formula can be found in FIG. 1 . (Gross-formula: C 20 H 30 N 6 O 12 Na 2 S 2 •[Pt(NH 3 ) 2 Cl 2 ]; molecular weight: 656.59 on C 20 H 30 N 6 O 12 Na 2 S 2 with Pt content 0.022-0.042%.)

The composite can be prepared by various methods. For example, the composite can result from the addition of a metal material to glutathione in the presence of an oxidant. Alternatively, the composite can result by the addition of a metal material to the oxidized glutathione-based compound.

Thus, another aspect of the invention provides a method for stabilizing a disulfide bond of an oxidized glutathione-based compound. “Stabilizing a disulfide bond” refers to a process for maintaining a bond between two sulfur atoms and preventing facile reversion of the oxidized glutathione-based compound (e.g., GSSG) back to the reduced form (e.g., GSH). Alternatively, stabilizing the disulfide bond can result in an increased lifetime of the oxidized glutathione-based compound. In the presence of reductants, the disulfide bond can cleave resulting in formation of the reduced form of the glutathione-based compound, which is an undesired reaction. By maintaining the glutathione-based compound in an oxidized form for a greater amount of time, the compound can be pharmaceutically effective for a correspondingly longer period of time in biological media.

In one embodiment, the disulfide bond can be stabilized by interacting the oxidized glutathione-based compound with a metal material. As discussed previously, the metal material is preferably a platinum or palladium material, such as cis-platin. In one embodiment, the platinum material is present in an amount of between about 0.0003 equivalent to about 1 equivalent relevant to the oxidized glutathione-based compound, preferably in a ratio of between about 0.001 equivalent to about 1 equivalent relevant to the oxidized glutathione-based compound.

In one embodiment, “interacting the oxidized glutathione-based compound with a metal material” comprises providing a glutathione-based compound and reacting this compound with an oxidant and a platinum material. A “glutathione-based compound” refers to any compound having a structure comprising a glutamic acid/salt/derivative bonded to a cysteine/salt/derivative bonded to a glycine/salt/derivative. Examples of glutathione-based compound include glutathione itself or any derivative, where a derivative can be prepared by reacting a reactive group with another chemical species. The resulting product will be an oxidized glutathione-based compound having a stabilized disulfide bond. Thus, in this embodiment, a glutathione-based compound is in a reduced form, such as GSH, and the reaction with a oxidant involves oxidizing the glutathione-based compound to produce a sulfur—sulfur bond. The oxidant can be any species which can cleave a S—H bond of a glutathione-based compound to produce a hydrogen atom and a compound having a sulfur-based radical which ultimately can react with another sulfur-based radical to provide the sulfur—sulfur bond. Various oxidants that can perform this S—H bond cleavage are well known in the art. In a preferred embodiment, the oxidant is selected from the group consisting of oxygen and hydrogen peroxide.

In this method, reacting a glutathione-based compound with an oxidant and the platinum material comprises an oxidation reaction. Relative amounts of the reactants are preferably about 1 equivalent of the glutathione-based compound with less than about 1 equivalent of the oxidant such as hydrogen peroxide, and more preferably, with about 0.9 equivalent of the hydrogen peroxide. In another embodiment, the oxidation reaction comprises reacting about 1 equivalent of the glutathione-based compound with between about 0.0003 equivalent and about 1 equivalent of the platinum material, preferably between about 0.001 equivalent and about 1 equivalent of platinum material, more preferably between about 0.001 equivalent and about 0.1 equivalent, and even more preferably between about 0.001 equivalent and 0.01 equivalent, in the presence of less than 1 equivalent of the oxidant. In another embodiment, about 1 equivalent of the glutathione-based compound is reacted with about 1 equivalent of the platinum material in the presence of less than 1 equivalent of the oxidant.

In one embodiment, the method involves oxidizing the glutathione-based compound with about 0.9 equivalent of hydrogen peroxide and about 0.00 1 equivalent of cis-platin. One advantageous feature of this method is an increased rate of oxidation of the glutathione-based compound. Another advantageous feature of this method is that the yield of the resulting composite is increased to an amount greater than about 98% and this increased yield is accompanied by an increased purity. The purification of this composite is simplified to a significant degree in that liquid chromatography can be performed to obtain a purity of the composite of greater than 99%, which complies with pharmaceutical standards. Prior art methods have achieved a purity of only 75-93% of oxidized glutathione, depending on the method.

In a preferred embodiment, the composite is synthesized in one step by oxidizing the reduced glutathione in the presence of cis-diamminedichloroplatinum, which may function as an oxidation reaction catalyst. The reaction conditions can be regulated accurately by using less than 1 equivalent of hydrogen peroxide. Consequently, formation of superoxidation products can be reduced, resulting in a near quantitative yield of the product. Thus, the one-step composite synthesis provides significant technological simplification and production of the composite GSSG•Pt with the stabilized disulfide bond.

In a preferred embodiment, the reaction is performed in a solution involving reduced glutathione as a monosodium salt and adding about 0.9 equivalent of the hydrogen peroxide and about 0.001 equivalent of cis-diamminedichloroplatinum at room temperature with stirring. The oxidation reaction typically proceeds in about 1.5-2 hours. Control for the completeness of the oxidation process can be conducted by an HPLC assay. The process is completed by the reaction solution lyophilic drying to produce the composite consisting of oxidized glutathione and cis-diamminedichloroplatinum in a mole ratio of 1000:1 (confirmed by spectral analysis on platinum and sodium). The peptide constituent of the obtained composite according to the data of an amino acid assay, a NMR ( 1 H) spectrum, retention time by HPLC corresponds to GSSG. The admixtures content do not exceed 2%, and the product yield as a disodium salt is 96-98% calculating for the dry composite.

A composite synthesis scheme can be found on FIG. 2 .

While not wishing to be bound by any theory, the increased stabilization of the disulfide bond can be the result of an interaction of the sulfur atoms with the platinum material (see also FIG. 4 ).

In an interaction between the platinum material and the oxidized glutathione (GSSG) molecule there is a possibility for ligand exchange, i.e., instead of the NH 3 groups, two sulphur atoms possessing two pairs of the lone-pair electrons can be involved in donor/acceptor bonds with the platinum atom. One can also consider the possibility for the addition in regard to the aforesaid stabilization of the disulfide bond due to the convergence of the NH 2 groups of the oxidized glutathione-based compound and stabilization of the general GSSG conformation (FIG. 5 ).

It is an advantageous feature of the present invention that obtaining derivatives of GSSG can produce a compound having different biological/chemical properties and/or activity. Thus, depending on the desired use of a drug comprising a composite including the oxidized glutathione-based compound, it is possible to obtain a particular drug for treatment of a particular disease. In addition, new chemical modifications of the oxidized glutathione-based compound, such as aminogroup acylation (for instance, bis-phenylalanyl-glutathione, and etc.), can result in a significant decrease in the risk of secondary reactions due to disulfide bond destruction. Reactions such as S-alkylation, oxidation to the corresponding acids, etc., can cause particular hardships in the working process and, in the case given, can be minimized or excluded.

The synthetic method of the present invention and physical-chemical modifications thereof directly in the course of the synthesis (the disulfide bond and general molecular conformation stabilization; the new reactive functional sites appearance) can result in obtaining the biologically active composite, such as the platinum material and GSSG, having new biophysical, chemical and biochemical parameters as dictated by the various structural-functional properties.

In one embodiment, the oxidized glutathione-based compound can be a derivative of glutathione. The glutathione can be derivatized after preparation of the composite, or it can be derivatized prior to preparation of the composite, i.e., the GSH can be derivatized prior to oxidation. FIG. 15 depict various examples of derivatives of glutathione-based compounds, i.e., oxidized glutathione-based compound. FIG. 15 a shows the structure of S-thioethylamine•glutathione disulfide. FIG. 15 b shows a structure of bis-[DL-6,8-thioetic acid]•glutathione disulfide. FIG. 15 c shows a structure of [β-alanyl-L-histidyl]•glutathione disulfide. FIG. 15 d shows a structure of [9-β-D-ribofuranosyladenyl]•glutathione disulfide. FIG. 15 e shows a structure of bis-[L-2-amino-4-[methylthio]butanoic acid]•glutathione disulfide.

In one embodiment, the oxidized glutathione-based compound has an acylated primary glutamic acid amino group. This variant is most suitable for acylation by N-protected activated amino acid derivatives, where after the stage of temporary protection of the cysteine mercapto-groups followed by condensation (activated ester method), and removal of the N- and S-protective groups and oxidation by the hydrogen peroxide with addition of cis-diamminedichloroplatinum results in the GSSG•Pt composite modified by amino-acids at the glutamic acid aminogroups. In this embodiment the oxidized glutathione-based compound can be selected from the group consisting of bis-[methionyl]•glutathione disulfide ( FIG. 16 a ), bis-[aspartyl]•glutathione disulfide ( FIG. 16 b ), bis-[histidyl]•glutathione disulfide ( FIG. 16 c ), bis-[3-iodine-tyrosyl]•glutathione disulfide ( FIG. 16 d ), [γ-aminobutanoyl]•glutathione disulfide ( FIG. 16 e ), bis-[γ-hydroxybutanoyl]•glutathione disulfide ( FIG. 16 f ), bis-[DL-6,8-thioetic acid]•glutathione disulfide ( FIG. 15 b ), and bis-[3,4-dihydroxyphenylalaninyl]•glutathione disulfide ( FIG. 16 g ).

When the composite includes phenylalanyl groups, the compound is bis-phenylalanyl-GSSG•Pt (see FIG. 7 ). According to this basic scheme (as shown in FIG. 22 ), all other GSSG•Pt modifications based on the aminogroups acylation by the derivatives of the protected amino acids, oxy-acids, carbonic acids and derivatives thereof are synthesized. Slight changes of the methods are possible due to a specific nature of modifying molecule. Protecting groups for the initial GSH compound include Bam (N-hydroxymethylbenzamide). The amino acid (AA) can be protected with groups such as BOC (butyl carbamate) or O—Su (N-oxysuccinimide ester; see FIG. 8 for specific details).

When the composite is bis-methionyl-GSSG•Pt, i.e., (Met) 2 GSSG•Pt, incorporation of a methionine group may involve BOC-protective group deblocking after the condensation stage.

When the composite is bis-aspartyl-GSSG•Pt, an aspartic acid group can be introduced according to the general aforementioned scheme. A temporary protective group for the β-carboxyl group is preferably removed, if possible, with the BOC-protective group simultaneously if needed. A β-tert-butyl ester of N-BOC-aspartic acid, i.e., BOC-Asp(OBu t )-OSu, can be applied at the condensation stage. The protective groups can be removed by trifluoroacetic acid (TFA).

When the composite is bis-histidyl-GSSG•Pt, a histidine imidazole ring can be protected via a di-tert-butyl-oxycarbonyl histidine derivative, i.e., BOC-His(BOC)-OSu, which can be used at the condensation stage. As in previous cases, the protective groups can be removed by trifluoroacetic acid.

When the composite is bis-3-iodine-tyrosyl-GSSG•Pt, a possible protecting group is an acid-labile protective group such as tert-butyl ester. The tyrosine derivative used at the concentration stage can be BOC-Tyr(OBut)-OSu.

When the composite is GABA-GSSG•Pt, (γ-aminobutanoyl-GSSG•Pt), an acid-labile protective tert-butyloxycarbonyl (BOC) group can be used at the condensation stage.

When the composite is GOBA-GSSG•Pt, (γ-hydroxybutanoyl-GSSG•Pt), an acid-labile group tert-butyl ester (which can be removed by a trifluoroacetic acid solution) can be used to protect a GOBA hydroxyl group. A derivative, used at the condensation stage, can be GABA(OBu t )-OSu.

When the composite is bis-lipoyl-GSSG•Pt, it is believed that side functional groups of lipoic acid do not require special protection. At the condensation stage it is possible to apply an activated (hydroxysuccinimide) ester of lipoic acid. There may be no need for a TFA treatment.

When the composite is bis-3,4-dihydrooxyphenylalanyl-GSSG•Pt (bis-DOPA-GSSG•Pt), to introduce DOPA molecule, it may be necessary to previously protect two hydroxyl groups of 3,4-dihydroxyphenylalanine by tert-butyl esters and to protect the aminogroup by a BOC-protective group. For condensation with a composite precursor, an activated ester can be obtained (hydroxysuccinimide or pentafluorophenyl one) that is used in excessive mole amount. Removal of the protecting groups can occur simultaneously with a trifluoroacetic acid solution.

When the composite is bis-[camosyl]-GSSG•Pt (bis-β-alanyl-L-histidyl-GSSG•Pt), carnosine can be protected as a di-BOC derivative of the β-alanine aminogroup and histidine imidazole group before condensation. Then condensation and following deblocking can be performed as previously described. A structure of bis-[carnosyl]-GSSG can be found in FIG. 19 a.

In another embodiment, the oxidized glutathione-based compound has an amide or phosphoramide bond to a unit selected from the group consisting of heterocyclic carbonic acids and nucleotides. In this embodiment, examples of the oxidized glutathione-based compound include bis-nicotinoyl-glutathione disulfide (bis-[pyridine-3-carbonyl]•glutathione disulfide) ( FIG. 17 a ), uridine-5′-monophosphatoyl•glutathione disulfide ( FIG. 17 b ), inosine-5′-monophosphatoyl•glutathione disulfide ( FIG. 17 c ), folliculylsuccinyl•glutathione disulfide ( FIG. 17 d ) and glycerol-1,3-diphosphatylglutathione disulfide ( FIG. 17 e ).

When the composite is bis-nicotinoyl-GSSG•Pt (bis-pyridine-3-carbonoyl-GSSG•Pt), a nicotinic acid containing no side functional groups can be introduced into condensation with a composite precursor without obtaining protected derivatives as corresponding activated esters such as hydroxysuccinimide or pentafluorophenyl. TFA treatment for the removal of protecting groups may not be required.

When the composite is uridine-5′-monophosphatoyl-GSSG•Pt (UMP-5′-GSSG•Pt), uridine-5′-monophosphate in presence of N,N-dicyclohexyl-carbodiimide can form phosphoamide links in reactions with amides (Chambers R. W., J.Am.Chem.Soc., 80, 3752, 1958). The composite precursor can have protected carboxyl groups, such as tetratrimethylsilyl derivatives to be used as an aminocomponent. Deblocking can proceed in mild water-alcohol systems.

When the composite is ionosine-5′-monophosphatoyl-GSSG•Pt, IMP-5′-GSSG•Pt, the synthetic scheme would most likely be similar to that of the previous derivative (UMP-5′-GSSG).

When the composite is folliculylsuccinyl-GSSG•Pt, a link between GSSG•Pt and estrone can be made by amide and ester bonds through a succinyl residue. Estrone can be transformed into an activated derivative by reaction with succinanhydride with following condensation by N,N-dicyclohexylcarbodiimide with a protected or blocked composite precursor and with tetra-trimethylsilyl derivatives as well. Deblocking can be performed in a water-alcohol system.

When the composite is glycerol-1,3-diphosphatyl-GSSG•Pt, the modification can proceed by a carbodiimide method using a composite precursor protected, as a tetra-trimethylsilyl derivative as an amino component, the synthesis is similar to that in the synthesis of phosphoamide derivatives (See Examples 13 and 14).

In another embodiment, the oxidized glutathione-based compound can be selected from the group consisting of tetra-dopamine•glutathione disulfide ( FIG. 18 a ) and theophylline•glutathione disulfide ( FIG. 18 b ). The formation of amide links can occur between composite carboxyl groups and amides. The reactivity of all four carboxyl groups is very similar and, therefore, a mixture of products can result.

When the composite is tetra-dopamine-GSSG•Pt, a 3,4-di-tert-butyl ester of dopamine can be used as an aminocomponent and di-tert-butyloxycarbonyl derivatives the composite can be used as a carboxyl component. Condensation can proceed by a N,N-dicyclohexyl-carbodiimide, and removal of the protective groups can be performed with a trifluoroacetic acid solution.

When the composite is GSSG•Pt-theophylline, theophylline can be used as an aminocomponent, a composite precursor can be used for a carboxyl component as a di-tert-butyloxicarbonyl derivative. Condensation can be performed with an “F” complex. The removal of protective group can be performed with a trifluoroacetic acid solution.

In another embodiment, the oxidized glutathione-based compound can include mixed disulfides. Possible combined structures can involve mixed disulfide formation (symmetric and non-symmetric). (See FIGS. 20 a - 20 c ).

One structure ( FIG. 20 b ) can be formed via mutual oxidation of mercaptogroups starting materials. There may be no need for additional protective groups and condensation methods.

Another compound ( FIG. 20 a ) can be obtained by formation of an amide bond between the cyteamine aminogroup and one of the composite precursor carboxyl groups. It may be necessary to introduce N-protective groups and to activate the composite precursor carboxyl groups. Due to the presence of four carboxyl groups it may be necessary to manipulate the stoichiometry and/or perform chromatographic separation of the resulting products.

The synthesis conditions are different from the structure 20 b by presence of the additional aminocomponent equivalent. At the chromatographic purification the structure 20 b is used a witness.

It is obtained from the structure 20 c through formation of an additional disulfide bond at the mercapto-group reaction. During the chromatographic separation of products, it may be necessary to have the structure 20 c as a witness.

In another embodiment, the oxidized glutathione-based compound can be a salt selected from the group consisting of alkali metal salts, alkaline earth metal salts, and transition metal salts. Examples of such salts include divanadate salts ( FIG. 21 a ), dihydrofluoride salts ( FIG. 21 b ), dilithium salts ( FIG. 21 c ), didopammonium salts, and dizinc salts ( FIG. 21 d ).

The salts can be obtained through addition of the corresponding amount of the salt-forming components, a base or an acid. Examples of salts with aminogroups includes a divanadate of GSSG•Pt((HVO 3 ) 2 -GSSG•Pt) or a dihydrofluoride of GSSG•Pt ((HF) 2 •GSSG•Pt). Examples of salts with carboxyl groups include a dilithium salt GSSG•Pt (see Example 2), a GSSG•Pt didopammonium salt or a GSSG•Pt zinc salt.

In another aspect of the invention, a drug comprising the composite is obtained according to the previously described method, such as the hexapeptide bis-(γ) -L-glutamyl)-L-cysteinyl-bis-glycine disodium salt and cis-diamminedichloroplatinum (cis-platin). Thus, the present invention provides a new class of medicinal substances “thiopoietins” that can be introduced into biological media, resulting in a new level of metabolism and cellular genetic activity.

An advantageous feature of the composite of the present invention is the biological activity, in particular:

Stimulation/modulation of the endogenous production for a significantly large range of the cytokine, growth and hemopoietic factors in conditions of radiation and chemical immunosuppression (IL-1α and β, IL-2, IL-3, IL-4, IL-6, IL-8, IL-10 and IL-12, TNF-α, IFN-α and IFN-γ, erythropoietin, colony-stimulating factors) (See Examples 5-7);

Reproduction of some cytokine effects (IL-2, IL-12, IFN-α and IFN-γ) due to the mechanism induction for the redox-sensitive expression of the immunologically significant genes and the key protein “critical” cysteine modification for the cellular signal-transducing systems (See Example 8);

Restoration of the depressed bone-marrow hemopoiesis including erythrocyte, leukocyte and platelet counts as well as levels of CD3 + , CD4 + , CD8 + , CD16/56 + , CD19/20 + , CD25 + , CD34 + , CD95 + (See Examples 9-13) at patients receiving radiation and high-dose combined chemotherapy;

In conditions of an active antibacterial, antiviral and antitumor chemotherapy, hepatotropic effects as well as diminution of the cardio-, hephro- and neurotoxicity signs;

The differentiated impact with regard to normal cells (including the ones being under functional stress) and transformed ones, namely, the metabolism, proliferation and differentiation stimulation at the normal cells/tissues and, simultaneously, the apoptosis mechanism induction only in the tumor- and/or virus-transformed cells. The data appears to support the induction of p53-dependent and p53-independent, Bcl-2-intensive apoptosis pathway/types occurring (See Examples 14-16).

The method for the production of the composite makes possible synthesis of different composites as a basis for design of drugs possessing a range of new features, namely:

Increased biochemical drug stability, i.e., “non-assailability” by the GSSG metabolism enzymes (i.e., far less accessible for these enzyme action), first of all, by NADP•H + -dependent glutathione reductase that basically increases the drug half-life time in the biological media exactly in the disulfide form;

New biophysical component with high level of the donor-acceptor potential;

Presence of new reactive sites within the said molecule and, therefore, entirely new capacity for chemical modification.

The composite properties allow it to function as a unique cellular “gyroscope” that in conditions of the extreme external environmental factors (physical, chemical and biological ones) provides restoration of a balance:

Within the cytokine profile, i.e., the cytokines regulating proliferation mainly; and the cytokines regulating mainly differentiation of the immunocompetent cells;

Ratio of the cellular redox potential including donor/acceptor balance of the electron dynamics due to restoration of the thiol-disulfide metabolism;

NAD/NAD•H and NADP/NADP•H ratios;

cAMP/cGMP ratio, changes of the extra- and intracellular ionized calcium;

Relationship of the transcriptional differentiation factors (NFκB) and proliferation factors (AP-1); relationship of the functional activity manifestations of p53, p21 and ras-proteins, therefore, balance of cellular proliferation, differentiation and apoptosis taking into account basically different exhibitions of these effects in the normal and transformed cells.

One embodiment of the present invention provides a method for stimulating endogenous production of cytokines and hemopoietic factors. The method includes the step of introducing to a mammalian body in need of such stimulation an effective amount of a composite comprising the oxidized glutathione-based compound and a metal material for a period of time to stimulate the endogenous production to obtain a therapeutic effect. As described previously, the ratio of the oxidized glutathione-based compound to the metal material is between about 3000:1 to about 1:1 where the metal material comprises a metal selected from the group consisting of platinum and palladium.

Therapeutic effect includes alleviation, prevention or curing of an unwanted body condition and can comprise a process selected from the group consisting of regulating proliferation in normal cells, regulating differentiation in normal cells, and inducing apoptosis of transformed cells where the transformed cells can include diseased cells. The therapeutic effect includes preventative, alleviation and curing effects in various diseases.

“Disease” refers to any unwanted condition of the body including, but not limited to, selected oncological diseases, infectious diseases, immunological diseases, ischemic diseases, neurodegenerative diseases, metabolic diseases, endocrinal diseases, and any other unwanted medical condition.

The composite can be administered by various methods: orally or as a solution form selected from the group consisting of inhalation solutions, local instillations, eye drops, intranasal introductions, an ointment for epicutaneous applications, intravenous solutions, injection solutions, and suppositories. Preferably, the glutathione is introduced parenterally or topically. The method is carried out by introducing the composite, derivatives or salts thereof to enhance the regulatory influence on stimulating of the cytokine and hemopoietic factor endogenous production; or to induce apoptosis mechanisms in transformed tissues, which provides regulation of metabolism, proliferation and differentiation in tissues and achieving a corresponding therapeutic effect.

In one embodiment, the composite is administered in a dosage of between about 0.1 mg/kg to about 1.0 mg/kg by body weight. In another embodiment, the composite is administered in a dosage of between about 1 mg/m 2 to about 100 mg/m 2 by body surface. In another embodiment, the drugs can be applied one or more times a day, by one or more day pulses or continuous administration until a desired therapeutic effect is achieved.

In a preferred embodiment, the GSSG•Pt material pharmaceutically acceptable derivatives are introduced to the body at a dose from 0.01 to 1.0 mg of GSSG•Pt material per kg of body weight for the GSSG•Pt material or salt thereof; or at a dose from 1 to 100 mg per 1 m 2 of body surface and in case when applied epicutaneously/through instillations at a dose from 1 to 100 mg per 1 m 2 of body surface as well, at least, once during each 24 hour period. Also the drug can be continuously injected or otherwise introduced to the body to have a 24 hour total dosage from 0.01 to 1.0 mg per kg of body weight for GSSG•Pt base and salts thereof, and from 1 to 100 mg per 1 m 2 of body surface during each 24 hour period. Preferably, administration and introduction to the body should be carried out until a desired stimulating effect on the cytokine and hemopoietic factor production or the apoptosis induction and, thus, the cellular metabolism, proliferation and differentiation regulation and corresponding therapeutic effect is obtained.

Where the composite is administered as a solution, preferably the solution has a concentration of between about 1% to about 10% of the composite. Preferably, the pharmaceutically acceptable derivatives of the GSSG•Pt material for parenteral use is in a pharmaceutically acceptable solvent as, for example, an aqueous solution including water, glucose solution, isotonic solutions of sodium chloride, buffered salt solutions. Other physiological solvents or carriers can be used. Where the composite is administered as an injectable form, preferably the injectable form comprises the composite in a solution in a concentration of between about 0.01% to about 3.0%.

For topical application including application for different body cavities, organic solvents or carriers may be used in the form of ointments, pastes, creams or suppositories.

The examples of the invention embodiments given below demonstrate feasibility of the invention practical use and confirm its effectiveness, and also expediency of using these medicinal drugs as an injectable solution containing 0.01% to 3% of GSSG•Pt base or the salts thereof with the dosage range from 0.1 to 1.0 mg/kg by body weight or from 1 to 100 mg/m 2 of body surface. In case when the GSSG•Pt drugs are administered like inhalation solutions, local instillations, eye drops, intranasal introduction, or an ointment for epicutaneous applications, or suppositories the recommended concentration range is from 1% to 10% of GSSG•Pt base or the salts thereof.

The active principle, the composite of the hexapeptide with the stabilized disulfide bond—GSSG•Pt—capable of stimulating/beneficial modulating the endogenous cytokine and hemopoietic factor production as well as inducing of transformed cells apoptosis, may be obtained by original, developed by the authors the peptide synthesis technique provided herein. Thereby, the obtained hexapeptide composite (GSSG•Pt) with purpose for subsequent usage in animals and humans is applied as a pharmaceutically acceptable GSSG•Pt derivative in an injectable drug form prepared by dissolving of the bulk substance in sterile water for injections or in any pharmaceutically acceptable solvent with the resultant concentration 0.01-3.0%. For an in vitro use in experimental settings, GSSG•Pt or the derivatives thereof may be dissolved in solvents acceptable for performance of corresponding experiments such as culture media, isotonic saline solutions, glucose solutions and the like.

Injectable medicinal forms of the GSSG•Pt, salts and compositions thereof have been tested in animal studies and as well in wide clinical studies and pilot trials on sick persons. The drug form for human and animal use should be prepared under sterile and pyrogen-free conditions while exerting every effort to prevent chemical or bacterial contamination of the medicinal form.

Using the maximum achievable concentration of the GSSG•Pt material sodium salt solution (10.0%, 100 mg/ml) in water for injections (or in normal saline), and using the maximum tolerable volumes administered to mice intra-peritoneally (IP, 2.0 ml), intravenously (IV, 0.5 ml), and intramuscularly (IM, 0.05 ml), there have been reached the GSSG•Pt dosage levels of 5000 mg/kg (IP), 1350 mg/kg (IV), and 135 mg/kg (IM), i.e. 1000, 270, and 27 times, respectively, have been obtained in mice, exceeding the maximum recommended human dose. In none of the cases either animal deaths or any toxic signs were observed, proving, in fact, the GSSG•Pt material in injectable drug form are essentially non-toxic.

Through chemical modifications of the basic GSSG•Pt molecule, it is possible to create new drugs where, in molecules along with the basic structure that have already demonstrated high medical-biological activity based on the oxidized glutathione composite with cis-diamminedichloroplatinum, there are fragments of other covalently-bound biochemically active molecules. Usage of the covalently bound combinations allows enhancing of a range of important drug characteristics such as stability and standardized properties of composition. Foundation for the chemical modifications is the GSSG•Pt hexapeptide core with two primary glutamic acid aminogroups, cysteine disulfide bond and carboxyl groups of glycine and α-carboxyl groups of glutamic acid (FIG. 6 ).

Purposely elected covalently-bound fragments of biochemically significant molecules can considerably improve medical-biological features of the basic GSSG•Pt material composite making them more selective for each particular therapeutic purpose, resulting in a sharp increase in a desirable treatment course. It might be conditioned with an additive effect of fragments in the biochemical activity mechanisms, sharp improvement of the basic molecule transport to a target-cell or a target-molecule, larger affinity for a receptor, necessary redistribution of oxidative-reductive (redox) potential and a range of other factors as well as combination thereof.

In one embodiment, the drug including the composite of the present invention can be useful for the treatment of a variety of oncological diseases. Included in these oncological diseases are solid tumors including those selected from the group consisting of lung cancer, melanoma, cerebral tumors, colorectal cancer, breast cancer, prostate cancer and ovarian cancer.

In one embodiment, manifestation of the immunological, biochemical and molecular-biological effects of the GSSG•Pt therapeutical impact can be obtained in the case when a combination comprising 50% of GSSG•Pt with all amino acids in L-form and 50% of GSSG•Pt with two chemically equal amino acids being represented in D-form and others being represented in L-form is used.

The present invention presents the advantageous feature that the drug comprising the composite or derivatives thereof has a regulating effect on the endogenous cytokine production processes and, thus, on the proliferation and differentiation processes of the T- and B-lymphocyte subpopulations (CD + -cells). Drug induction can result in production of a wide cytokine and hemopoietic factor range and CD + -lymphocytes. Therefore, in this range, from the point of view of cytokine interaction, there are both agonist-cytokines and antagonist-cytokines regarding the effects they stimulate (e.g., “relationship” of IL-1α and β and IL-4). In connection with that, depending on the initial patient's immunogenesis system state, hyper- or hypoactivity, the drugs of the present invention can restore a disturbed balance in the system.

The given provision is illustrated in Examples 9-13 which show that patients with depressed immunity (oncological patients receiving radiation or combined chemotherapy) the cytokine synthesis induction (IL-1α and β, IL-2, IL-3, IL-4, IL-6, IL-10 and IL-12, IFN-α and IFN-γ) can be accompanied by restoration of CD3 + , CD4 + , CD8 + , CD16/56 + , CD25 + , CD34 + counts; and patients with the immunoautoagression signs—at the clones of cytotoxic lymphocytes or fibroblasts in case of viral hepatitis C the Fas-Ag (CD95 + ) is expressed that promotes the apoptosis mechanism induction and elimination of the virus-transformed and/or “aggressive” cells.

Another advantageous feature of the present invention involves the finding of the composite impact on the isolated human lymphocytes 10 minutes (a peak is observed at the 30 th minute (the maximal level of phosphorilating of the cytosol proteins obtained from the lymphocytes)) after parenteral introduction of GSSG•Pt material, a significant increase of the phosphorylating level on tyrosine for lymphocyte cytosole proteins that is an integrative characteristic for the cellular signal-transducing system activity. These changes in state for key factors of cAMP, cGMP, inositol-phosphate-dependent signal systems owing to the GSSG•Pt material influence (See Example 8) calls forth the redox-sensitive gene expression, first of all, for the immunologically significant genes responsible for the cytokine and hemopoietic factor synthesis. Therefore, the GSSG•Pt material application in the treatment purposes not only stimulates the cytokine and hemopoietic factor endogenous production but also provides reproduction of the biochemical and physiological cytokine effects, in particular, in the case of sensitivity loss of receptors to cytokines that is observed at oncological and retroviral pathology.

In the tumor- and/or virus-transformed cells the apoptosis mechanisms are induced through the GSSG•Pt material multicytokine-activating impact, its influence on p53-dependent and p53-independent apoptosis induction mechanisms as well as through changing of the donor/acceptor n-electron balance in malignant (cancer) cells (see Examples 14-16).

Depending on the initial patient's biological status including his immunity condition: immunodeficiency, i.e., hyporeactivity; or immunoautoaggression, i.e., hyperreactivity; presence of the tumor- or virus-transformed cells—the composite and/or pharmaceutically acceptable derivatives thereof are able to act as the endogenous cytokine production stimulators/modifiers and/or as the apoptosis mechanism inducers, respectively.

These compounds and the drug forms thereof obtained which include the GSSG•Pt material composite are applied as medicinal drugs capable in the therapeutic purposes depending on the initial subject's biological status of the subject in need thereof to stimulate/modulate the wide range cytokine and hemopoietic factor endogenous production and/or to reproduce the cytokine effects as well as to perform the differentiated effect regarding the normal (the metabolism, proliferation and differentiation regulation) and the transformed cells (the apoptosis mechanism induction). “Transformed cells” refers to tumor- and/or virus-transformed cells.

Performed experimental and clinical investigations show that therapeutic effects of the drugs obtained from the GSSG•Pt material and derivatives thereof are based on the multicytokineactivating action and capacity to reproduce cytokine and hemopoietic factor effects. At the same time, the data was obtained indicating the GSSG•Pt material has a direct antitumor effect, especially regarding GSSG•Pt material salts administered in pharmaceutically acceptable drug forms. Moreover, the GSSG•Pt material effect has revealed to be different for normal and tumor cells. The research with use of the normal and tumor cells demonstrated that the GSSG•Pt material or the GSSG•Pt material in pharmaceutically acceptable compositions initiated tumor cell death through apoptosis mechanism. In case of normal cells, they did not undergo destruction (See Examples 14-16).

Also high effectiveness of the applied medicinal drugs based on the GSSG•Pt material in regard to apoptosis mechanism induction in the virus-transformed cells, for example, in case of viral hepatitis B and C, should be noted as exemplified in Examples 11-13.

Therapeutic effects of GSSG•Pt material and pharmaceutically acceptable derivatives thereof, particularly, salts thereof for the treating of oncological, infectious (viral) diseases can be explained as a stimulation of the wide-ranged endogenous cytokine production with a unique ability to activate apoptotic death of the transformed cells exclusively. Moreover, the majority of the GSSG•Pt therapeutical effects and the pharmaceutically acceptable derivatives thereof in the experimental and clinical conditions can be applied to be connected with revealed properties of the GSSG•Pt material and the drug forms thereof to stimulate/beneficially modulate the endogenous cytokine production or to reproduce their effects in regard to stimulation of the normal cell proliferation and differentiation and, at the same time, to activate apoptotic death of the transformed cells exclusively.

Another advantageous feature of the drugs of the present invention is a correcting influence of the GSSG•Pt material and the salts thereof on the metabolic abnormalities, particularly, on the impairment of carbohydrate metabolism at diabetes, type II. In this case (See Example 7) restoration of the normal cAMP/cGMP ratio as well as the thiol-disulfide ratio in tissues due to the GSSG• Pt material impact (vanadium salt thereof) provided stable setting to normal values for the glucose content in the patient blood, which is a considerable therapeutic effect.

Resuming the results of performed experimental, preclinical and clinical studies of the medicinal remedies group developed on the GSSG•Pt material one should emphasize that the parenteral (intravenous, intramuscular, subcutaneous, instillations into urinary bladder or per rectum, etc.) introduction of the indicated medicinal remedies provides: a) stimulation/beneficial modulation of the endogenous production of IL-1α and β, IL-2, IL-3, IL-4, IL-6, IL-8, IL-10 and IL-12, TNF-α, IFN-α and IFN-γ, erythropoietin, G-CSF, M-CSF and GM-CSF; and, thereupon, wide range of biochemical and immunological effects; b) reproduction of the effects of the said cytokines and hemopoietic factors in case of cytokine receptor desensitization; as well as—c) induction of apoptosis mechanism in tumor- or virus-transformed cells only, calling forth in the organism of the subject in need thereof the corresponding therapeutic effect.

The beneficial effects of the drug of the present invention can be illustrated in FIGS. 25-27 . FIG. 25 delineates the humoral and cellular responses to the drugs comprising the composites of the present invention. FIG. 26 depicts the components of the immune system activated by the drugs of the present invention, the components including platelets, white blood cells, red blood cells, cytokines, erythropoietines, T-lymphocytes, neutrophils, monocytes, macrophages, natural killer cells, and β-lymphocytes. FIG. 27 depicts the types of cytokines stimulated by the drugs of the present invention, the cytokines including IL-1, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, alpha and gamma interferons, TNF-alpha and GM-CSF.

Thus, the novel method for obtaining the composite comprising the GSSG•Pt material the new medicinal substance (thiopoietins) class is applied and proved, in that therapeutical effects are determined by firstly found and previously unknown properties of performing stimulation of cytokine and hemopoietic factor endogenous production and their effect reproduction, thereby, performing stimulation and/or modulation of the normal cell proliferation and differentiation as well as inducing apoptosis mechanisms in virus- and tumor-transformed cells.

The presence of a chemical interaction between the disulfide bond of the oxidized glutathione-based compound and the platinum material may play a biophysical role in the electron balance of biological systems. While not wishing to be bound by any theory, the chemical interaction can be loosely thought of as a donor/acceptor pair where the lone electron pairs on the sulfur atoms can potentially interact with an electron-deficient material, such as the platinum material. Again, while not wishing to be limited by any mechanism, if cellular activity and cellular physical state are determined, at least in part, by donor/acceptor interactions throughout a biological system, then a balance among electron donors and acceptors having equal biopotentials can be a life parameter. Such balance alteration can be used for regulation of different cell functions and physical properties (Szent-Gyorgyi A., Proc. Natl. Acad. Sci. U.S., 58,2012 (1967); Introduction to a Submolecular Biology, Academic Press, New York (1960)). Sources of mobile electrons can include π-electrons such as lone-pair electrons of nitrogen, oxygen, and sulfur. There are few acceptor groups (e.g., —C═O— groups) in a normal cell which can be balanced via donor/acceptor dynamics of donor electrons such as π-electrons.

Continuing along with this non-limiting theory, the malignant cell can be characterized as having dramatic disturbances of the donor/acceptor balance towards an excess of donors electrons. Acceptor molecules are almost absent in cancer cells. A possible solution to this imbalance in this situation is the presence of molecules that possess donor/acceptor features within the same molecule, such as a GSSG•Pt material. Introducing GSSG•Pt into biological media can cause a restoration of the electronic balance in the biological media. This restoration can involve a catalysis by the platinum atom in a reaction involving the formation of an active oxygen form, e.g., superoxide anion radicals, singlet oxygen.

Another non-limiting theory involving cellular electronic balance is an interaction of GSSG•Pt material with cell GSH generating oxidative-reductive, i.e. donor/acceptor pair. If there is a high GSH level in cells that is characteristic for tumor-transformed cells with a high proliferative impulse, the pro-oxidative, i.e. oxidative, properties of GSSG•Pt material exhibit in the most evident way. In the case the oxidative stress forms in the tumor cells only causing alteration of the tumor cells mitochondria functions forming intracellular signal for the apoptosis mechanisms induction.

For the normal but “tired”, “exhausted” cells, there may be an oxidative-reductive potential optimization, bioenergetic supply for the metabolic transformations, redox-sensitive adequate expression of the genome functional sites, in particular, the immunologically significant genes and transcription factors.

For the transformed cells GSSG•Pt, there may be an incompatibility with vital functions involving chain transfer reaction of π-electrons, disturbance of the mitochondrial oxidative-reductive reactions of electron/protons transfer reactions along the respiratory chain and dislocation of the NADP•H + /NADP•H ratio, i.e., forming the intracellular signal for the apoptosis mechanism induction.

The new GSSG•Pt pharmacokinetics (comparing to GSSG by itself) in blood and tissues (organs) being introduced into biological media indicates that the GSSG•Pt molecule is much less available for the GSSG metabolism enzymes and, first of all, for the NADP•H + -dependent reductase, the main enzyme for the GSSG into GSH reduction. Thereupon, the GSSG•Pt half-life time in the disulfide form in biological media increases significantly (See Examples 3 and 4).

Basically novel pharmacokinetics of the hexapeptide with the stabilized disulfide bond (GSSG•Pt) compared to the structural analog, i.e., the oxidized glutathione (GSSG), provided an optimal manifestation for the newly determined biological-pharmacological effects.

EXAMPLES OF THE INVENTION EMBODIMENTS

Synthesis Method. 170 g (0.55 mole) of the reduced glutathione are suspended in 200 ml of water and, along with stirring, 139 ml (0.55 mole) of the 4N NaOH solution and 170 ml of 0.05% cis-diamminedichloroplatinum cis-[Pt(NH 3 ) 2 Cl 2 ] water solution are added.

The obtained transparent, slightly yellow solution is cooled to 18-20° C. and 283 ml of the 3% hydrogen peroxide solution (H 2 O 2 solution) is added in little portions over a time period of five minutes with such a speed rate that the reaction mixture temperature will not exceed 22-25° C.

Thirty minutes after addition of the hydrogen peroxide solution (H 2 O 2 ) the pH is measured, and then the 4N caustic soda solution is added drop-by-drop to reach pH=5.6-5.8 along with simultaneous temperature control, which should be within 22-25° C. Then the cooling is taken away and stirring continued at indoor (room) ° C. temperature for 30 minutes more.

Control of the oxidation reaction completeness is performed by the HPLC assay. A liquid chromatograph for HPLC, type Beckman, Sol. Module 126, Det. 168, with a column Luna Phenomenex ODS 4.6×250 mm, or an identical one, is prepared. To prepare the HPLC mobile phase 20 cm 3 of acetonitrile and 1 cm 3 of freshly distilled trifluoroacetic acid is introduced into a 1000-cm 3 graduated flask, and the volume is increased up to the mark by the deionized water. The solution is mixed and degassed by shaking in vacuum.

Thirty minutes after addition of the entire hydrogen peroxide solution amount one will check the oxidation reaction completeness by means of the highly productive liquid chromatography (HPLC). Thereto with a microsyringe one will take 10 μl of the reaction mixture and dissolve them in 1 ml of the mobile phase (0.1% trifluoroacetic acid: acetonitril, 98:2). 20 μl of the obtained solution is introduced into the chromatograph Beckman 126 Solvent Module, Diod Array Detector Module 168, the column Luna Phenomenex ODS 4.6×250 mm, or the identical.

The retention time in the aforesaid conditions is 5.0+0.5 min for reduced glutathione, 11.0±0.5 min for oxidized glutathione.

In case if, according to the HPLC data after the standard chromatogram integration, the oxidized glutathione content is less than 97%, the stirring is continued in the same regime 30 minutes more and the HPLC control is repeated.

In case when the result is equal or exceeds 97%, the reaction is considered as completed and one will pass to the reaction solution filtration. Thereto, there is used a filter having pore size not larger than 0.7 μm.

Weight loss at drying will not exceed 5% at drying to the constant weight at 100° C. in vacuum (1 mm Hg) above CaCl 2 and P 2 O 5 .

The main material content in the ready product by the HPLC data will not be lower than 98%.

EXAMPLE 3

Pharmacokinetics and Metabolism of GSSG•Pt and GSSG in Blood Serum and Tissues After Intravenous Introduction

The time-concentration GSSG curves and activity changes for enzymes participating at the GSSG metabolism after the GSSG•Pt and GSSG intravenous introduction in different doses were studied. The variation of the oxidized glutathione concentration was evaluated in animal blood serum, liver, kidneys, spleen and lymphocytes during 60 min. after the single GSSG•Pt and GSSG intravenous introduction in doses 2 mg/kg and 20 mg/kg of body weight. In addition, the activity variation of the enzymes participating in GSSG metabolism was evaluated (glutathione A reductase, glutathione-peroxidase, glutathione-S-transferase, γ-glutamyl-transpeptidase).

The study was performed at male CBA mice (standard body weight—180 to 200 g). Five groups of animals (with no less than 15 mice in each) were formed. The group description is represented below.

Control groups:

#1—intact animals receiving a single injection of the tested article vehicle (normal saline—(NS)) instead of the drug;

Test groups:

#2—animals receiving the GSSG injection (GSSG dissolved in normal saline) in a dose of 2 mg/kg;

#3—animals receiving the GSSG injection (GSSG dissolved in normal saline) in a dose of 20 mg/kg;

#4—animals receiving the GSSG•Pt injection (GSSG•Pt dissolved in normal saline) in a dose of 2 mg/kg;

#4—animals receiving the GSSG•Pt injection (GSSG•Pt dissolved in normal saline) in a dose of 20 mg/kg.

The blood samples were taken at 1, 2, 5, 10, 20, 40 and 60 min., the serum was separated and the concentration analysis was performed according to a standard method where the main stages are protein precipitation, removal from the sample of non-polar and medium-polar compounds and the following chromatographic analysis with spectrophotometric detection in conditions of isocratic and linear gradient elution.

The GSSG content variation in the blood serum, different organs and the lymphocytes at the drug intravenous introduction are given in the Tables 1-4.

Activity of the enzymes participating in the GSSG metabolism (glutathione reductase: EC.1.6.4.2; glutathione-peroxidase: EC.1.11.1.9; glutathione-S-transferase: EC.2.5.1.18; g-glutamyl-transpeptidase: EC.2.3.2.2) were determined by the standard reagent kits produced by Boehringer Mannheim GmbH. The enzyme activity variation values after the GSSG•Pt and GSSG intravenous introduction in dose of 2 mg/kg are given at the Tables 5, 6, 7.

Comparing the drug dynamic distribution of the drugs in the blood serum, liver, kidneys, spleen and lymphocytes a clear advantage for the GSSG•Pt pharmacokinetics regarding GSSG is evident. The GSSG concentration to the 10 th minute is almost equal to the initial one whereas, at the same time, the GSSG•Pt concentration exceeds 50 times the initial parameters and remains at the given high level till the end of the studied period. Besides, the maximal GSSG•Pt concentration in the blood serum and in the tissues exceeds 3 times the maximal GSSG concentration. These features determine higher effective duration of impact for GSSG•Pt comparing to GSSG.

As it follows out of the Tables 5, 6,7 materials the GSSG drug increases approximately two times the activity for the enzymes participating in the thiol metabolism with large number of proved indices whereas the GSSG•Pt drug does not significantly alter the enzymes activity and the proved indices number is insignificant. It indicates the greater GSSG•Pt drug stability as a substrate in regard to main enzymes participating in the glutathione metabolism and, therefore, calls out longer presence of the glutathione oxidized form in the blood serum and different organs.

Thus, the obtained data analysis demonstrated the higher GSSG•Pt stability to selective impact of the main glutathione metabolism enzymes (first of all, glutathione-reductase) that determines new dynamics for the drug pharmacokinetics. It facilitates manifestation of new biological-pharmacological effects and, thereupon, new GSSG•Pt therapeutic effects.

Conclusion.

It was demonstrated at the comparative analysis for the GSSG•Pt and GSSG drugs that the main GSSG•Pt pharmacokinetic parameters (maximal blood concentration and effective drug influence duration) obtained both by the direct method and by the estimation on model exceed about 2-3 times the main GSSG pharmacokinetic parameters. The integral indices showing the drug blood presence duration determined by calculation of the square under the GSSG•Pt pharmacokinetic curve exceed 4 times the corresponding indices regarding to GSSG. Thus, due to more advantageous pharmacokinetic parameters the GSSG•Pt drug has higher pharmacological activity and biological availability comparing to the GSSG drug.

EXAMPLE 5

Effect of GSSG•PT and GSSG on Cytokine Production by Human Peripheral Blood Mononuclear Leukocytes in vitro

Oxidized glutathione (GSSG) as well as a structural analog thereof, which is a hexapeptide with a stabilized disulfide bond, were evaluated for their effect on cytokine production by human peripheral blood mononuclear leukocytes in vitro.

The leukocytic cytokine production was triggered by adding a mitogen, concanavalin A (ConA) to the cell culture immediately after introducing the test substances. In 24 hours of the cellular exposure to ConA and the test articles, the culture supernatants were sampled and stored until cytokine determination at −70° C.

With the aim of evaluating the functional status of the cells and their capacity of responding to the mitogen in the presence of the test articles at each concentration level, the control cell cultures, containing the test articles in identical concentrations, were incubated for 72 hours following the initial concomitant introduction of ConA and the test substances. Sixteen hours prior to the incubation completion, 3 H-thymidine was added, and the label rate of incorporation into DNA was interpreted as the criterion of the cellular test system functional state.

Venous blood from male healthy volunteers was collected into plastic heparinized tubes (endotoxin tested). PMNL fraction was isolated by centrifugation in density gradient of Ficoll and sodium diatrizoate (Histopaque-1077; Sigma).

Cell concentration was adjusted to 2×10 6 per 1 mL of culture medium (RPMI 1640, Sigma) containing: HEPES (20 mM); L-glutamine (2 mM); Gentamicin (50 mg/mL); fetal calf serum (10%). All the reagents used were of cell culture tested grade, Sigma. Cell viability was estimated by the Trypan blue exclusion method and 100 mL of cell suspension (200,000 cells) were placed into each well of flat bottom 96-well sterile microtiter plates for tissue cultures. Cells from each subject were placed into no less than 39 wells.

The five following final concentrations of the test articles (GSSG, as well as GSSG•Pt) were evaluated: 5000 mg/mL; 500 mg/mL; 50 mg/mL; 5 mg/mL; and 0.5 mg/mL. Each concentration was established in no less than six wells by adding 50 mL of medium containing the appropriate quantity of the previously dissolved test articles. Another six wells were used for control cultures: only 50 mL of medium was added.

Immediately after the test articles had been introduced into the cultures, 50 mL of medium containing ConA (Sigma, cell culture tested) in a quantity required for a final concentration of 4.0 mg/mL, was added to all the wells excepting three additional ones which served for evaluation of spontaneous 3 H-thymidine uptake (without ConA).

After a 24-hour incubation at 37° C. and 5% of CO 2 , contents of three wells (from each sextuplet of identical wells) were taken out, centrifuged, and the supernatants were frozen and kept at −70° C. until the cytokine assay was to be performed. Cultures in the other three wells (of each sextuplet) were incubated further under the conditions described above.

Fifty-six hours after the incubation had begun, 1.0 mCi of 3 H-thymidine was added into all the remaining cultures, the plates were incubated for another 16 hours, and then the contents of the wells were harvested and transferred onto glass-fiber filters which were consequently treated with 5% trichloroacetic acid and ethanol. The filters were dried and their radioactivity (counts per minute, cpm) was determnined using liquid scintillation counter, Betaplate 1205 (LKB).

Mean radioactivity values for triplicates of identical cultures were used to calculate the index of mitogenic stimulation: the ratio of averaged cpm values for ConA stimulated cultures to averaged cpm values for unstimulated ones (three wells without ConA). This stimulation index for wells, where the test articles were present in various concentrations, served as a criterion of cellular functional status, and ability of the cells to respond to mitogenic stimulation.

Supernatants of 24-hour culture triplicates were subsequently assayed for cytokine content only if their 72-hour matched control culture triplicates developed mitogenic response to ConA with value of the stimulation index in the range from 15 to 50.

Concentrations of interleukin-1b (IL-1b), interleukin-2 (IL-2); interleukin-3 (IL-3); interleukin-4 (IL-44); interleukin-6 (IL-6), interleukin-8 (IL-8); interleukin-10 (IL-10); interleukin-12 (IL-12); tumor necrosis factor-α, g (TNF-α, g), and interferon-α, g (IFN-α, g) were determined by ELISA using commercial reagent kits (Medgenix, Belgium) and were expressed in pg/mL of culture supernatants.

The salient findings given in Tables 8, 9. As one can see from Tables 8 and 9, the adding of GSSG and GSSG•Pt into the culture media resulted in statistically significant and dose-dependent stimulation of the cytokine production by human mononuclear leukocytes. However, GSSG•Pt stimulating influence was more significant (1.5-2 times as much) on the studied cytokine production with stimulation and regulation for production of the wider cytokine range in comparison with the GSSG effect. One can clearly see correlation of the interrelated cytokine changes (increasing of IL-1b, IL-2, TNF-a,g along with decreasing of IL-4, IL-10) in the Tables 8 and 9.

Thus, the GSSG•Pt impact on the human peripheral mononuclear leukocytes in vitro was manifested with considerable stimulation of the wider cytokine range release into culture media considering their reciprocal regulative effect, and, thereby, it confirmed the GSSG•Pt stimulatory and regulatory effect on the natural cytokine-producing capacity of the human blood cells.

EXAMPLE 6

Effect of GSSG and GSSG•Pt on Cytokine and Hemopoietic Factor Production as Well as On Hemopoiesis and Immunity Parameters in Cyclophosphamide-induced Hemo- and Immunodepression

1. The oxidized (GSSG) glutathione as well as the structural analog thereof, which is the hexapeptide with the stabilized disulfide bond, were evaluated in a murine model of hemo- and immunodepression induced by a single administration of cytostatic agent Cyclophosphamide (CP).

The study was designed to evaluate the effect of a five-day long administration of the test articles on the capability of the CP-treated murine splenocytes to produce interleukin-1 (IL-1 α,b); interleukin-2 (IL-2); interleukin-3 (IL-3); interleukin-4 (IL-4); interleukin-6 (IL-6), interleukin-8 (IL-8); interleukin-10 (IL-I0); interleukin-12 (IL-12); tumor necrosis factor-α, g (TNF-α, g), interferon-α, g (IFN-α, g) and G-CSF, M-CSF, GM-CSF in vitro. In addition, the blood leukocyte and lymphocyte count and the bone marrow cellularity (karyocyte count) were determined at eight days after CP administration. Some animals receiving CP were then challenged with sheep red blood cells (SRBC), and the humoral immune response to the antigen was evaluated.

Male CBA mice (180 to 200 g body weight) were given a single introperitoneal injection of CP in a dose of 50 mg/kg. Four groups of animals (with no less than 15 mice in each) were formed. The group description is represented below.

Control groups:

#1—intact animals receiving a single injection of normal saline (NS) instead of CP injection, which further were treated with test article vehicle (normal saline);

#2—animals receiving a single CP injection, which further were treated with test article vehicle (normal saline);

Test groups:

#3—animals receiving a single CP injection, which further were treated with the test article (GSSG dissolved in normal saline) in a dose of 5 mg/kg;

#4—animals receiving a single CP injection, which further were treated with a GSSG•Pt (dissolved in normal saline) in a dose of 5 mg/kg.

Twenty-four hours after the CP injection, five animals in each group were immunized with SRBC (10 7 cells in 0.5 mL of NS, intra-peritoneally).

On day 3 after the CP injection (24 hours after the immunization) the intraperitoneal injections of the test or reference articles were started (as it has been described above). Injections were performed during five days: once a day, daily.

Twenty-four hours after the completion of five-day treatment course (on the 8 th day after the CP injection), mice were euthanized and splenocyte cultures were aseptically prepared for assessment of spontaneous cytokine and hemopoietic factor production by the spleen lymphocytes in vitro.

Simultaneously, blood and marrow samples were collected for blood leukocyte, lymphocyte, and marrow nucleated cell counts.

Serum samples from immunized animals were tested on level of SRBC agglutinins (day 8 after the CP injection, and day 7 after the immunization).

Table 10 shows the parameters of cytokine and hemopoietic factor production by splenocytes, bone marrow and blood count indices, and the immune response to sheep red blood cells in mice receiving the test articles against the background of cyclophosphamide induced hemo- and immunodepression.

According to the Table 10 data, the GSSG•Pt administration set to norm the cytokine and hemopoietic factor production while GSSG performed only exiguous stimulating effect. Besides, GSSG•Pt stimulated production for the wider cytokine and hemopoietic factor range as well as had significant regulatory influence on shift with respect of the cytokine status that was confirmed with the positive correlation of the interrelated cytokine changes at the corresponding pathologic process.

Thus, the GSSG•Pt use in CP-induced hemo- and immunocompromised animals results in a prominent stimulation and regulation on the cytokine and hemopoietic factor endogenous production along with restoration of the bone marrow and blood cellular indices as well as immune response development to sheep red blood cells.

2. The purpose of the present study was to explore the GSSG•Pt efficacy on the cyclophosphamide-induced cytopenia (myelopenia) model.

The study was conducted on the white male rats weighing 160.0 g. Cyclophosphamide was introduced once subcutaneously at the back in doses 50 mg/kg (a vehicle was water for injections).

Four groups of animals (with no less than 15 mice in each) were formed. Group description is represented below.

Control groups:

#1—intact animals receiving a single injection of normal saline (NS) instead of CP injection, which further were treated with test article vehicle (normal saline);

#2—animals receiving a single CP injection, which further were treated with test article vehicle (normal saline).

Test group:

#3—animals receiving a single CP injection, which further were treated with GSSG•Pt (dissolved in normal saline) in a dose of 5 mg/kg.

On day 2 after the CP injection the intraperitoneal injections of the test or reference articles were started (once a day, during 10-15 days).

At the end of each series (10 and 15 days) the experimental groups were euthanized through ether overdose and peripheral blood (tail veins) and bone marrow (femora) were taken for the analysis. The hematological studies were conducted with the unitized standard methods. The peripheral blood analysis results are represented in the Table 11; myelogram analysis results are given in the Table 12.

Analyzing Table 11 results one can note that cyclophosphamide in the dose 50 mg/kg was found to perform the marked cytopenic effect at all of the formed blood elements with absolute and relative lymphopenia depending on the observation terms (maximally exhibited at the day 15).

It should be noted that four animals died: on the 9 th , 10 th , 12 th , and 14 th days. In fact, all these animals demonstrated flabbiness, hypodynamia, weight loss.

The GSSG•Pt introduction provided the significant stimulating effect. The general state improvement, positive weight changes were observed, and the immature cell form appearing in blood indicated the bone-marrow hemopoiesis activation. The death of the animals was not noted.

Analysis of the myelogram revealed that cyclophosphamide in the dose 50 mg/kg was found to perform the significant myelotoxic effect. Erythro-, trombocyto- and lymphopoiesis are especially suppressed. Myelosuppression is the most marked at the 15 th day.

The GSSG•Pt administration had the considerable myelostimulating effect.

The drug GSSG•Pt in the dose 15 mg/kg being introduced as the daily course during 10-15 days exerts the marked myelostimulating effect at the cyclophosphamide-induced cyto- and myelopenia. The drug administration improves the general state, it positively influences at the body weight changes and lowers mortality by about 30%.

EXAMPLE 7

Effect of GSSG and (Li-GSSG•Pt) on Cytokine and Hemopoietic Factor Production as Well as on Hemopoiesis and Immunity Parameters in Radiation-induced Hemo- and Immunodepression

Both oxidized (GSSG) and the structural analog thereof, which is the lithium salt of the hexapeptide with the stabilized disulfide bond (Li•GSSG•Pt), were evaluated in a murine model of hemo- and immunodepression induced by a single irradiation in a total dose of 1 Gy.

The study was designed to evaluate efficacy of seven-day daily administration of the test articles (with the dosing started two hours post-exposure) on the capability of the splenocytes from mice exposed to radiation to produce interleukin-1 (IL-1α,b); interleukin-2 (IL-2); interleukin-3 (IL-3); interleukin-4 (IL-4); interleukin-6 (IL-6), interleukin-8 (IL-8); interleukin-10 (IL-10); interleukin-12 (IL-12); tumor necrosis factor-α, g (TNF-α, g), interferon-α, g (IFN-α) and G-CSF, M-CSF, GM-CSF in vitro. In addition, the blood leukocyte and lymphocyte counts and the spleen and bone marrow cellularity (karyocyte count), as we well as splenic and medullary colony-stimulating capacity, were determined at the 8 th day post-exposure.

Male CBA mice (18 to 20 g body weight) were irradiated with single dose of 180 kV X-rays filtered with 0.5 mm Cu (at 15 mA, distance—70 cm, duration two min. and 28 sec.). The total absorbed dose comprised approximately 1 Gy.

Four groups of animals (with no less than 12 mice in each) were formed. Group description is represented below.

Control groups:

#1—intact animals receiving a sham irradiation procedure to reproduce a stress impact, which further were treated with the test article vehicle (normal saline);

#2—control animals irradiated in a dose of 1 Gy, which further were treated with test article vehicle (normal saline).

Test groups:

#3—animals irradiated in a dose of 1 Gy, which further were treated with the test article (GSSG dissolved in normal saline) in a dose of 5 mg/kg;

#4—animals irradiated in a dose of 1 Gy, which fuirther were treated with the test article (Li•GSSG•Pt dissolved in normal saline) in a dose of 5 mg/kg.

Two hours after the irradiation the intraperitoneal injections of the test or reference articles were started (as it has been described above). Injections were performed during seven days: once a day, daily.

Twenty-four hours after the completion of seven-day treatment course (on the 8 th day after the irradiation), mice were euthanized and splenocyte cultures were aseptically prepared for assessment of spontaneous cytokine and hemopoietic factor production (interleukin-1 (IL-1α,b); interleukin-2 (IL-2); interleukin-3 (IL-3); interleukin-4 (IL-4); interleukin-6 (IL-6), interleukin-8 (IL-8); interleukin-10 (IL-10); interleukin-12 (IL-12); tumor necrosis factor-α, g (TNF-α, g), interferon-α, g (IFN-α, g) and G-CSF, M-CSF, GM-CSF) by the spleen lymphocytes in vitro.

Simultaneously, blood, spleen and marrow samples were collected for blood leukocyte and lymphocyte, and spleen and marrow nucleated cell counting.

Additionally, hemopoietic colony-formation ability of spleen and bone marrow cells was assessed by the method of colony-forming unit (CFU) direct count in the spleens of irradiated singenic CBA mice receiving intravenously spleen or bone marrow cells obtained from animals of control or test groups.

Splenocytic levels for the cytokine and hemopoietic factor production, blood, bone marrow, and spleen cellular indices as well as the colony-forming parameters (colony-forming units, CFU) at the bone marrow and spleen of the irradiated animals at the 8 th day post-exposure, are summarized in Table 13.

As is evident from the table data, the Li•GSSG•Pt administration results in statistically significant recovery of the cytokine and hemopoietic factor production by splenocytes, whereas GSSG produces less significant effect. However, LiGSSG•Pt influences endogenous production for the wider cytokine and hemopoietic factor range as well as regulates the cytokine status alterations with respect of the corresponding pathologic process.

Thus, the Li•GSSG•Pt usage as an applied method in animals with developed radiation-induced hemo- and immunodepression results in pronounced stimulation-regulation of the endogenous cytokine and hemopoietic factor production, and also leads to an effective recovery for the cellular compositions of the blood, lymphoid and hemopoietic organs as well as the bone marrow and spleen colony-forming activity.

EXAMPLE 8

Effect of the GSSG•Pt Composite and Salts Thereof on Processes of Phosphate Modification as Well as on Content of Lymphocytes Bearing IL-2 Receptors

The molecular mechanisms of the reproduction of the immuno-biochemical effects of the cytokines with the GSSG•Pt composite and the salts thereof were studied.

At the study action of the GSSG•Pt composite and the salts thereof: sodium (Na), lithium (Li) and magnesium (Mg)—was evaluated at the murine model of hemo- and immunodepression induced by single administration of cytostatic cyclophosphamide (CF).

At this study the effect of a five-day long administration of the test articles on the capability of the phosphorylating level of the lymphocyte cytosol proteins on tyrosine and content of the “active” lymphocytes-carriers of IL-2-receptors were evaluated.

Male CBA mice (18 to 20 g body weight) were given a single peritoneal injection of CP in a dose of 50 mg/kg. After the CF injection the animals were introduced with the tested articles in dose of 5 mg/kg 24 hours later. The tested articles were introduced during five days (daily, once a day). Twenty-four hours after completion of the tested article introduction the mice were euthanized and blood samples were collected to conduct the study.

A fraction of mononuclear leukocyte was obtained by centrifugation in gradient of ficoll-metrizoat (Histopaque, Sigma). Cell concentration was adjusted to 2×10 6 cells per 1 ml of cell culture medium (RPMI 1640), containing 20 mM HEPES, 2 mM glutamine, 50 mg/mL gentamicin and 10% fetal calf. Cell viability was estimated by the Trypan blue exclusion method, then the cell suspension was placed into wells of 96-well microliter plates—200,000 cells per well.

Content of the lymphocytes-carriers of the IL-2-receptors was determined according to Horgan A. F. (1994) on smears of mononuclear slip. Mononuclear antibodies to chains p55 and p75 of the IL-2-receptor were used as the first antibodies. To reveal the first antibodies the polyclonal rabbit antibodies against murine immunoglobulins marked with were used. Count of the lymphocytes-carriers of the IL-2-receptors was made in percentage to the number of total lymphocytes.

For metabolical marking lymphocytes were cultivated in the Igla medium with addition of 10% cattle serum. The metabolical marking with [32P]ortho-phosphoric acid was performed by cell incubation during 10-12 hrs. in the phosphorusless medium DME containing 100 μCi/ml of [32P]ortho-phosphate. On each sample 0.2 ml of the medium with isotope were added. After incubation cells were destroyed by pipetting and centrifuged at 6000 g for 30 min. The obtained supernatant was used for immunoprecipitation with polyclonal antibodies to phosphotyrosine at Fu method (1992). Protein A-sefarose was used for the precipitation of immune complex. The precipitate was washed three times and the precipitate activity was counted on “Gamma” counter.

According to the results of the conducted study (Table 14), it was found that action of the GSSG•Pt composite on the isolated lymphocytes causes (see Table 14) at 10 minute or significant increase of the phosphorylating level on tyrosine of the lymphocyte cytosol proteins, which is the integral indication of the activity of the signal-transducing systems. These changes due to the GSSG•Pt composite action, largely due to the GSSG•Pt composite derivative action determine the modulation of the redox-sensitive gene expression, first of all, immunologically important genes, responsible for the synthesis of the cytokines and hemopoietic factors.

In Table 15 the data is given on phosphorylating level on tyrosine of the lymphocyte cytosol proteins and percentage of the lymphocytes-carriers of IL-2-receptors in CBA-line mice received the tested articles having cyclophosphamide induced hemo- and immunodepression.

Application of the GSSG•Pt composite salts results in the increase of the percentage of the lymphocytes-carriers of IL-2-receptors and almost normalizing their quantity (normal one is 18.3±1.6%). The similar regularity was found when phosphorylating level on tyrosine of the lymphocyte cytosol proteins was studied.

Application of the GSSG•Pt composite salts results in restoration of the percentage of the lymphocytes-carriers of IL-2-receptors in immunodeficiency conditions modeled by cyclophosphamide. There is the increase of the phosphorylating level on tyrosine of the lymphocyte cytosol proteins of the signal-transducing systems that can be one of the factors of the described immunostimulating actions of the articles tested.

Thus, the example provides evidence of GSSG•Pt to reproduce (imitate) the regulatory effects of the range of cytokines, first of all, IL-2. We are intending to mean the induction by the GSSG•Pt composite of the intracellular mechanisms performing regulatory cytokine signals on he system of immunocompetent and hemopoietic cells as the IL-2 effect reproduction. The conducted studies have shown that changing of the phosphorylating level on tyrosine of the lymphocyte cytosol proteins of the signal-transducing systems of the cells of the organs immunogenesis and hemopoiesis in conditions of cyclophosphamide modeled immunodeficiency causes the effect of the dynamic normalization of the active lymphocyte content.

Therefore, application of the GSSG•Pt composite and derivatives thereof in the form of therapeutically purposed medicinal drugs not only stimulates the cytokine and hemopoietic factor endogenous production but also provides the reproduction of the immune-biochemical cytokine effects, especially in case of receptors desensitization observed mainly in oncological and retro-virus pathology.

EXAMPLE 9

Stimulation of Endogenous Cytokine Production and the Therapeutic Effect of the GSSG•Pt Application in a Patient with a Stomach Cancer, Peritoneal Metastases, Ascites, Splenomegaly and Cholestatic Hepatitis

A 33-year old patient was diagnosed as having stomach neoplasm for more than two years (adenocarcinoma of moderate differentiation degree). In 1993 the patient was operated for malignant stomach ulcer and numerous dense lymph nodes were found in the porte hepatis which were considered to be metastases.

In January 1994 the course of chemotherapy (5-FU) was complicated by the severe cholestasis and percutaneous drainage of the left and right liver ducts was undertaken, that six months later was followed by the choledochoejunostomy with changeable transliver drains with Brown's anastomosis.

In November 1995 the patient's state worsened. According to the examinations the patient experienced an active secondary hepatitis. The liver was enlarged and painful and protruded from the costal arch up to 5-6 cm. Blood chemistry indices proved to be persistently abnormal and hardly corrected by the performed treatment: bilirubin—40.0 due to indirect (up to 31.0); activity of amino-transferases—approximately six times higher than upper normal limit, hypoalbunemia was up to 26%; and there was also hypergammaglobulinemia; hypercholesterolemia was up to 10.2 mmol/l.

During fibrogastrocopy (November, 1995) a stomach cancer located in the middle area of the stomach body and extended about 8 cm was confirmed. The tumor was solid-like type. Stomach walls were rigid. Histology examination defined the tumor as adenocarcinoma of moderate degree differentiation. In December, 1995, the patient had an explorative laparotomy. Ascites was found with plural metastases all over the peritoneum, splenomegaly. The patient's case was identified as inoperable.

A decision was taken to apply GSSG drug form. The drug was injected parenterally (intramuscularly and intravenously), and additionally, the drug form was used via local injections around the tumor tissue through an endoscope. An average doses which were used for intramuscular and intravenous injections—0.1-0.5 mg/kg, and for local injections—up to 50 mg in situ. Parenteral injections of the drug were applied every other day, b.i.d. (intravenous injections at the morning, and intramuscular ones—at the evening), during three weeks, and after that, two times a week during four weeks. The drug introduction through the endoscope was performed once in seven days. Two months after the beginning of the treatment with the drug form used the fibrogastroduodenoscopy showed: esophagus was passable, mucous membrane was pink, cardia rosette was partly closed. On empty stomach moderate amount of foamy secretion was in the stomach, which was intensively colored with bile. The tumor extent was 4.8 cm. At the same time, substantial improvement of hematology and blood chemistry indices was found and the liver size decreased up to 3 cm (below the costal arch).

Six months after the treatment completion (July, 1996) the patient's state worsened significantly. According to the examination the secondary hepatitis relapsed. The liver was increased in size and tender, protruded 4 cm beyond the costal arch. Blood chemistry indices were abnormal and hardly corrected by the performed treatment: bilirubin—360 due to indirect (up to 28.0); activity of amino-transferases—approximately four times higher than upper normal limit, hypoalbunemia was up to 21%; and there was also hypergammaglobulinemia; hypercholesterolemia was up to 9.42 mmol/l.

At the fibrogastrocopy (July, 1996) a stomach cancer located in the middle area of the stomach body and extended about 6 cm was confirmed. The tumor was solid-like type. Stomach walls were rigid. Histology examination defined the tumor as a moderate degree differentiation adenocarcinoma. In August, 1996, the patient had an explorative laparotomy. Ascites was found with plural metastases all over the peritoneum, splenomegaly.

Considering the previously conducted therapy the decision was taken to apply the new drug GSSG•Pt that is the structural analog of the former administered GSSG drug. The drug was introduced according to the identical regime: parenterally (intramuscularly and intravenously), and additionally, the drug form was introduced via local injections around the tumor tissue through an endoscope. An average doses which were used for intramuscular and intravenous injections—0.1-0.5 mg/kg, and for local injections—up to 50 mg in situ. Parenteral injections of the drug were applied every other day, b.i.d. (intravenous injections at the morning, and intramuscular ones at the evening), during three weeks, and after that, two times in a week during four weeks. The drug introduction through the endoscope was performed once in seven days.

Two months after the treatment initiation with the applied drug: the liver protruded 1 cm beyond the costal arch, tenderless at palpation. According to the ultrasound examination data: there is fibrous tissue at the place of previously determined cancer sites. At the fibrogastrocopy: the esophagus was passable, mucous membrane was pink, cardia rosette was partly closed. The gastric walls are elastic. There was moderate amount of foamy secretion in the stomach with saliva in empty stomach. The tumor extent was 1.5 cm. The duodenum was freely passable. At the same time, substantial improvement of hematology and blood chemistry indices was indicated.

Comparing the therapeutical efficacy of the drugs GSSG•Pt and GSSG using of the former one was found to be advantageous that was manifested by the positive changes at the clinical, biochemical, hematological and immunological indices, fibrogastrocopy data (the tumor size decrease at 75% while applying GSSG•Pt comparing to the 40% decrease after the GSSG administration) (Tables 16, 17). Moreover, at the Table 17 one can see that GSSG•Pt stimulates production of the wider cytokine and hemopoietic factor range having a regulatory influence on their content change.

Thus, the treatment according to the present invention resulted in considerable regress of tumor process with simultaneous obvious beneficial changes in hematology, blood chemistry and immunology parameters, and significant improvement of the life quality.

Patient's state after the treatment course completion: The patient's state is satisfactory. He noticed significant reduction of weakness, no pains in the right under the ribs and in the joints. As patient said the narcotic abstinence state diminished almost without pain and in less time. Biochemical indices normalization and absence of the viral replicative activity was marked.

Conclusion: The immunomodulating therapy course with the GSSG•Pt drug provided positive changes, which were indicated by: biochemical and serologic indices normalization; termination of HCV replication. Immune indices and cytokine status parameters correlate to the infectious process controlling and viral replication absence. Examination of the patient's peripheral blood lymphocytes by liquid chromatography with monoclonal antibodies to FasAg (CD95 + ) after the treatment revealed the CD95 + cell increase indicating activation of the programmed cell death process in virus-infected cells. At supervision at one and three months after the treatment stabilization of this state was noted.

Concomitant drug intoxication and an abstinence state at application of the GSSG•Pt drugs were corrected faster and were less excruciating for the patient.

The immunomodulating course with the GSSG•Pt drugs for chronic hepatitis C with replicative activity and concomitant drug intoxication has provided the following results:

biochemical indices normalization in blood;

hematological indices normalization;

termination of HCV replication;

normalization of the immune blood indices and cytokine status;

apoptosis process induction in the peripheral blood lymphocytes;

rapid correction for the drug abstinence state;

stable therapeutic effect

EXAMPLE 14

Comparative Analysis of the GSSG and GSSG•Pt Effects on Growth Development and Apoptotic DNA Degradation at Normal and Transformed Cells

The GSSG and GSSG•Pt effects on growth development and apoptotic DNA degradation at normal and transformed (HL-60) cells were comparatively analyzed. To that end, GSSG and GSSG•Pt were incubated for 24 hours with HL-60 myeloid line cells and normal human lymphocytes obtained from healthy volunteers' blood.

Venous blood of healthy volunteers was collected into heparinized test-tubes, which had been tested for endotoxin. A mononuclear fraction of blood leukocytes was obtained by centrifugation in ficoll-metrizoat gradient (Histopaque, Sigma). Cell concentration was adjusted to 2×10 6 cells per 1 ml of cell culture medium (RPMI 1640), containing 20 mM HEPES, 2 mM glutamine, 50 mg/mL gentamicin and 10% fetal calf serum. Cell viability was estimated by the Trypan blue exclusion method, then the cell suspension was placed into wells of 24—and 96-well microliter plates—250,000 cells per well.

The HL-60 myeloid line cells were grown in RPMI-1640 medium with addition of 10% fetal calf serum. Cultivation was carried out in closed flasks, the medium volume was 12 mL, it was replaced every four days. Directly before testing the cell suspension in the fresh medium was brought into 24-well microliter plates (cell concentration for each well was 250.000 cells per well) and the tested articles—GSSG and GSSG•Pt—were added into the corresponding wells up to final concentration 100 mg/mL.

The effect testing for the testing articles was performed 24, 48 hours after addition into the culture.

The analysis procedure involved the following: after 24-48 hour incubation there were calculated the total cell count and the dead cell count by the Trypan blue exclusion method; afterwards the cell suspension was centrifuged (at 12.000 g, in Eppendorf test-tubes during 10 min). The cell pellet was frozen and kept at −70° C. before the DNA separation. The DNA separation was conducted by Kirbi-Georgiyev phenol method. To the cell pellet there were added 0.5 ml of 10% SDS and 0.5 ml of TE-buffer containing 0.1M EDTA and 0.01 M Tris-HCl with pH 8.0 (“A” buffer), and the pellet was resuspended by the tube shaking during 15 min. Then the equal phenol amount was added adjusted by 0.01 M Tris-HCl with pH 8.0, the product was mixed during two min. and centrifuged in the Eppendorf test-tubes at 12.000 g during 15 min. After the centrifugation completion the upper water phase was phenol-treated one more time. After the phenol treatment the upper water phase was twice treated with phenol-chloroform mixture (1:1) that was mixed with the water phase in equal amount. The water phase was separated by centrifugation at 12.000 g during 10 min., pumped out and once mixed with the equal chloroform amount. Afterwards it was centrifuged at 12.000 g, the upper phase was separated, mixed with double amount of distilled ethyl alcohol frozen to −20° C. and kept for one night at −20° C. The DNA pellet was gathered by centrifugation at 12.000 g during 10 min., the supernatant was removed and the pellet was washed by 200 mL of 70% ethyl alcohol frozen to −20° C. during five min., centrifuged one more time at the same conditions and afterwards the pellet was air-dried during one hour. Then it was diluted in 10 mL of the A buffer; the DNA amount was determined by Dishe method and electrophoresis was performed in 2% agarose gel (agarose with NA grade made by “Pharmacia LKB, Biotechnology Inc” (Austria) was used). The DNA electrophoretic separation was made in a block of 2% agarose gel in a device made by “Pharmacia LKB, Biotechnology Inc” (Austria). As a buffer solution 0.04 M tris-HCl buffer, pH 7, containing 0.02 M of sodium acetate and 0.02 M EDTA was applied. Agarose (2%) was prepared at an electrode buffer. The DNA samples (2-5 mg) were placed into the gel slots. The electrophoresis was conducted with an electrical field intensity of 6 W/cm during three hours. The sample propulsion was observed due to bromine-phenol blue motion. On the electrophoresis completion the gel block was taken out of the device and introduced into a tray with etidium bromide solution (3 mg/mL H 2 O) for 30 minutes in dark place. After the incubation completion the gel was rinsed with water and examined in the transmitted ultraviolet radiation with the wave-length 254 nm at a transilluminator made by “Pharmacia LKB, Biotechnology Inc” (Austria). The gel was photographed by Zenit E camera with a red colour filter.

The study results are given in the Tables 28 and 29 and FIGS. 13 and 14 . As one can see in the Tables 28 and 29 data, the GSSG and GSSG•Pt influence on normal and transformed cells is of an alternative character. GSSG and GSSG•Pt stimulated the normal cell proliferation (Table 28). The electrophoresis of DNA obtained from the normal cells (Table 28) revealed presence of only traceable quantities for apoptotic fragments at the background of homogenous high-molecular fraction hcaracteristic for the viable cells.

In the contrary, in the myeloid origin (HL-60) cancer cell culture, the apoptosis activation and the cell division inhibition were observed due to the influence of both drugs(Table 29, FIG. 14 ). The diversities of the effects were of the quantitative nature.

Thus, the dead HL-60 cell quantity after the GSSG impact was reliably lower than the one after the GSSG•Pt effect (Table 29). An evident indication for stronger impact efficacy (GSSG•Pt comparing to GSSG) on the HL-60 cells is the apoptotic fragment's character obtained after the electrophoretic analysis. The DNA electrophoresis of the HL-60 cells non-incubated with the drugs demonstrated presence of highly-molecular, practically homogenous DNA characteristic for the viable cells ( FIG. 14 , band #2). The DNA electrophoresis of the cells incubated during 24 and 48 hours with the GSSGoPt and GSSG drugs revealed the DNA oligonucleosomic degradation ( FIG. 14 , bands 1 and 3, respectively), i.e., an apoptotic ladder, that is indisputable sign for the programmed cell death. However, the apoptotic ladder for the HL-60 cells treated with GSSG contained considerable amount of the high molecular DNA characteristic for the viable HL-60 cells ( FIG. 14 , band #1), whereas the high molecular DNA for the cells treated with GSSGoPt was virtually absent ( FIG. 14 , band #3).

The HL-60 cells are defective in the p53 gene (p53 gene deletion) and apoptosis induction through the GSSG and GSSG•Pt treatment can occur only without involving the p53 product. Therefore, one can state that the GSSG and GSSG•Pt drugs activate an inner contour of the programmed cell death irrespectively of the p53 gene product. The p53 defect is present approximately at half of cancer pathology cases. The experimental results appeared to denote efficacy of GSSG and, especially, GSSG•Pt for these tumor chemotherapy.

Conclusion: The performed studies allowed to obtain data indicating capacity of the GSSG and GSSG•Pt drugs to increase normal cell (lymphocytes) viability and, contrariwise, to induce apoptosis in ransformed cells, i.e., exercise an antitumor activity. Besides, the GSSG•Pt activity regarding to the transformed cell apoptosis induction excelled significantly the one for the GSSG drug according to the objective viability criterion, i.e., presence of the high molecular DNA that appeared considerably after the GSSG treatment and was almost absent after the GSSG•Pt treatment. Thus, the data obtained on cells of the myeloid line HL-60 defective in the p53 gene that is the crucial agent in apoptosis induction allows us to state that:

The GSSG and GSSG•Pt drugs induce the inner contour of the apoptosis development regardless of the p53 gene product;

The GSSG•Pt drug based on composite possesses higher chemotherapeutic activity (due to the apoptotic induction in the transformed cells) versus the first generation drug GSSG.

EXAMPLE 15

Analysis of the GSSG•Pt Effects on Growth Development and Apoptotic DNA Degradation at Normal and Transformed Cells Defective in the p53 Antioncogene with Increased Ras-gene Expression

The GSSG•Pt effects on growth development and apoptotic DNA degradation of different lineage of transformed cells (HL-60, C-8, A-4) were comparatively analyzed depending on the p53 defect that is the key factor for the apoptosis development and the ras-gene that is a multipotent factor for cell reaction. The HL-60 cell culture is human cells of myeloluekosis origin defective in the p53 gene. Cell cultures C-8 and A-4 are transformed murine fibroblasts having a plasmid with the ras gene and a gene of the E1a expression enhancement factor that is an adenovirus antigen fragment. At that, the A-4 cells are defective at the p53 gene and the C-8 ones contained the intact p53 gene. A donor blood lymphocyte slip was used as a control of the human cells with the intact p53 gene.

The HL-60 (p53−−) myeloid line cells were grown in RPMI-1640 medium with addition of 10% fetal calf serum. The cell suspension cultivation was carried out in closed flasks, the medium volume was 12 mL, it was changed every four days. Directly before testing the cell suspension in the fresh medium was brought into 24-well microliter plates (cell concentration for each well was 250.000 cells per well) and the tested article—GSSG•Pt—was added into the corresponding wells up to final concentrations 10-100 mg/mL.

Venous blood of healthy volunteers was collected into heparinized test-tubes, which had been tested for endotoxin. A blood leukocyte mononuclear fraction was obtained by centrifugation in ficoll-metrizoat gradient (Histopaque, Sigma). Cell concentration was adjusted to 2×10 6 cells per 1 ml of cell culture medium (RPMI 1640), containing 20 mM HEPES, 2 mM glutamine, 50 mg/mL gentamicin and 10% fetal calf serum. Cell viability was estimated by the Trypan blue exclusion method, then the cell suspension was placed into wells of 24—and 96-well microliter plates—250,000 cells per well.

The murine transformed fibroblasts were grown in DMEM medium with addition of 10% fetal calf serum. The cell suspension cultivation was carried out in closed flasks, the medium volume was 12 mL, it was changed every four days. Directly before testing the cell suspension in the fresh medium was brought into 24-well microliter plates (cell concentration for each well was 50.000 cells per well) and the tested article—GSSG•Pt—was added into the corresponding wells up to final concentrations 10-100 mg/mL.

The effects testing for the testing articles was performed 24, 48 hours after introduction into the culture.

The analysis procedure involved the following: after 24-48 hour incubation, the total cell count and the dead cell count were calculated by the Trypan blue exclusion method; afterwards the cell suspension was centrifuged (at 3.000 g, in Eppendorf test-tubes during 10 min). The cell pellet was frozen and kept at −70° C. before the DNA separation. The DNA separation was conducted by Kirbi-Georgiyev phenol method. To the cell pellet there were added 0.5 ml of 10% SDS and 0.5 ml of TE-buffer containing 0.1M EDTA and 0.01 M Tris-HCl with pH 8.0 (“A” buffer), and the pellet was resuspended by the tube shaking during 15 min. Then the equal phenol amount was added adjusted by 0.01 M Tris-HCl with pH 8.0, the product was mixed during two min. and centrifuged in the Eppendorf's test-tubes at 12.000 g during 15 min. After the centrifugation completion the upper water phase was phenol-treated one more time. After the phenol treatment the upper water phase was twice treated with phenol-chloroform mixture (1:1) that was mixed with the water phase in equal amount. The water phase was separated by centrifugation at 12.000 g during 10 min., pumped out and once mixed with the equal chloroform amount. Afterwards it was centrifuged at 12.000 g, the upper phase was separated, mixed with double amount of distilled ethyl alcohol frozen to −20° C. and kept for one night at −20° C. The DNA pellet was gathered by centrifugation at 12.000 g during 10 min., the supernatant was removed and the pellet was washed by 200 mL of 70% ethyl alcohol frozen to −20° C. during five min., centrifuged one more time at the same conditions and afterwards the sediment was air-dried during one hour. Then it was diluted in 10 mL of the A buffer; the DNA amount was determined by Dishe method and electrophoresis was performed in 2% agarose gel (agarose with NA grade made by “Pharmacia LKB, Biotechnology Inc” (Austria) was used). The DNA electrophoretic separation was made in a block of 2% agarose gel in a device made by “Pharmacia LKB, Biotechnology Inc” (Austria). As a buffer solution 0.04 M tris-HCl buffer, pH 7, containing 0.02 M of sodium acetate and 0.02 M EDTA was applied. Agarose (2%) was prepared at an electrode buffer. The DNA samples (2-5 mg) were placed into the gel slots. The electrophoresis was conducted with an electrical field intensity of 6 W/cm during three hours. The sample propulsion was observed due to bromine-phenol blue indicator motion. On the electrophoresis completion the gel block was taken out of the device and introduced into a tray with etidium bromide solution (3 mg/mL H 2 O) for 30 minutes in dark place. After the incubation completion the gel was rinsed with water and examined in the transmitted ultraviolet radiation with the wave-length 254 nm at a transilluminator made by “Pharmacia LKB, Biotechnology Inc” (Austria). The gel was photographed by Zenit E camera with a red color filter.

The study results are given in the Tables 30, 31, 32, 33. As is evident from the Table 31, GSSG•Pt induces apoptosis in the HL-60 cell culture defective at the p53 gene. The effect was rather developed at the concentration of 10, however, it was more evident at 100 mg/mL. Also there were observed conglomeration of DNA apoptotic fragments multiple of DNA nucleosome size that is the indisputable sign of programmed cell death.

In contrary, GSSG•Pt made stimulating effect on normal cells, i.e., there was certain proliferation observed (Table 30). Electrophoresis of DNA obtained from normal cells exhibited that it was represented by a homogenous high-molecular fraction characteristic for viable cells.

Thus, differences of the drug action on normal and transformed cells were basically divergent. Mechanism for the GSSG•Pt divergent action might be conditioned by activation of the p53-independent apoptotic pathway through the ras-signal-transducing system. The ras-system is capable to stimulate cell proliferation and differentiation through the mitogenic factor cascade and induce apoptosis (programmed cell death) through another cell signal cascade.

To check it there were compared the GSSG•Pt effects on murine fibroblasts with enhanced ras-gene expression but different in the intact p53 gene (wild type) presence—cells C-8(p53++), or the p53 gene absence (a genetic defect)—(cells A-4(p53−−)). As one can see from the Tables 32 and 33, the GSSG•Pt effect appeared in both cell lineages. The apoptosis induction was significantly exhibited. It indicates activation of the p53-independent apoptotic pathway. Presence of the activated ras gene in both of the cell lineages can be an explanation for the apoptotic exhibition that was even more marked in the transformed fibroblasts than in the HL-60 cells. It confirmed the apoptosis induction through the ras-signal-transducing system. The GSSG•Pt effect on the A-4 and C-8 cells was not different at concentration of 10 mg/mL. The significantly superior GSSG•Pt effect on the A-4 cells comparing to the C-8 cells was noted at the concentration 100 mg/mL. The p53-protein absence appeared even to enhance the ras-signal-transducing pathway for apoptosis induction in tumor cells.

The p53 gene defect occurs in approximately half of the cancer disease cases. The results of these experiments can imply the GSSG•Pt effectiveness for chemotherapy of these tumors.

Conclusion: The data from these studies indicate the capacity of the GSSG•Pt drug to increase normal cell (lymphocytes) viability and, contrariwise, to induce apoptosis in transformed cells, i.e., exercise an antitumor activity. Besides, the GSSG•Pt activity regarding to the transformed cell (defective at the p53 gene) apoptosis induction even excelled the one for the cells with the intact p53 gene at the high drug concentration. According to the objective viability criterion, i.e., presence of the high molecular DNA that appeared in considerable amounts after the GSSG•Pt treatment of the normal donor cells (take from the lymphocyte slip), the cell death was practically absent whereas in case of the GSSG•Pt impact on transformed cells there was observed the DNA apoptotic degradation, i.e., the sign of the irreversible apoptotic death induction even in the cells defective at the p53 gene (with the stimulation especially). Previously, in the Example 9 there was shown activation of the cytokine range after the GSSG•Pt treatment. Considering that the cytokine action may be determined with the ras-signal-transducing pathway activation the cytokine stimulation cam also cause the antitumor effect through an interaction with the ras-protein.

EXAMPLE 16

Analysis of the GSSG•Pt Effects on Growth Development and Apoptotic DNA Degradation at Murine Transformed Cells Cultures Defective at Antioncogenes

The GSSG•Pt effects on growth development and apoptotic DNA degradation of transformed fibroblasts of a cell lineage with activated ras-gene but an intact p21 gene (p21++− C-8 cells) and murine cell lineage with knockout p21 gene (p21−−).

The p21++ lineage cells are murine transformed fibroblasts having a plasmid with the ras gene and a gene of the E1a expression enhancement factor that is an adenovirus antigens fragment but have intact p53 and p21 genes. The p21 (−−) lineage has the intact p53 and ras genes but it is defective at the p21 gene. It allows evaluating the GSSG•Pt impact on the apoptosis induction in conditions of impaired regulation for the cell division G1 phase.

The cell cultures were grown in DMEM medium with addition of 10% fetal calf serum. The cell suspension cultivation was carried out in closed flasks, the medium volume was 12 mL, it was changed every four days. Directly before testing, the cell suspension in the fresh medium was brought into 24-well microliter plates (cell concentration for each well was 50.000 cells per well) and the tested article—GSSG•Pt—was added into the corresponding wells up to final concentrations 100 mg/mL.

The effect testing for the testing articles was performed 24, 48 hours after introduction into the culture.

The analysis procedure involved the following: after 24-48 hour incubation, the total cell count and the dead cell count were calculated by the Trypan blue exclusion method; afterwards the cell suspension was centrifuged (at 3.000 g, in Eppendorf test-tubes during 10 min). The cell pellet was frozen and kept at −70° C. before the DNA separation. The DNA separation was conducted by Kirbi-Georgiyev phenol method. The cell lysis was performed by addition of 0.5 ml of 10% SDS. The equal phenol amount was added there adjusted by 0.01 M Tris-HCl with pH 8.0, the product was mixed during two min. and centrifuged in the Eppendorf test-tubes at 13.000 g during 15 min. The phenol deproteinization was repeated twice. Afterwards the water phase was twice treated with phenol-chloroform mixture (1:1) and once with chloroform. Nucleic acids were precipitated by the addition of two volumes of 96% ethyl alcohol at 20° C. overnight. The DNA was gathered by centrifugation at 13.000 g during 30 min., decanted, washed with 70% ethyl alcohol and air-dried. After the drying the precipitate was dissolved in TE buffer. The DNA concentration was determined in the obtained solution (by Dishe method). Fractional content of the nucleic acids was determined by electrophoresis in 2% agarose gel (agarose with NA grade made by “Pharmacia LKB, Biotechnology Inc” (Austria) was used). The DNA electrophoretic separation was made in a block of 2% agarose gel in a device made by “Pharmacia LKB, Biotechnology Inc” (Austria). The electrophoresis was performed in TAE buffer pH 7.4 (0.04 M tris, 0.02 M of sodium acetate, 0.02 M of EDTA) at an electrical field intensity of 6 W/cm during three hours. The sample propulsion was observed due to bromine-phenol blue indicator motion. The electrophoresis results were examined in the transmitted ultraviolet radiation (λ=254 nm) at a transilluminator made by “Pharmacia LKB, Biotechnology Inc” (Austria) after the gel dying with etidium bromide solution (5 μg/ml).

The study results are given in the Tables 34, 35. As it is evident from the Table 34, GSSG•Pt induces apoptosis in the p21++ cell culture with activated ras-gene manifested by conglomeration of DNA apoptotic fragments multiple of DNA nucleosome size.

In the p21 (−−) cells having non-active ras-signal-transducing system but defective at the control of the cell cycle delay in the G1 phase GSSG•Pt induced apoptosis to less extent that in p21++ cells (Tables 34, 35). It might be implicated by the fact that the ras-system is capable of stimulatin cell proliferation and differentiation through the mitogenic factors' cascade and inducing apoptosis (programmed cell death) through another cell signals' cascade. Absence of the p21 gene expression can cause changes in interrelations of specific cascades of the ras-signal-transducing pathway and, thereupon, lessen the apoptotic stimulation by the drug in cases of p21 gene defects.

The p21 gene defect does not often occur in oncological diseases that considering the performed experiments' issues can imply the GSSG•Pt effectiveness for chemotherapy of these tumors except cases with lower effectiveness at tumors with mutations in p21 gene.

Conclusion: The performed studies allowed obtaining data indicating capacity of the GSSG•Pt drug to induce apoptosis actively in transformed cells, i.e., exercise an antitumor activity. The enhanced ras-gene expression facilitates the apoptosis induction in the transformed cells C-8 indicating implementation of the GSSG•Pt antitumor activity through the ras-signal-transducing system. The lesser drug effect in case of p21 gene expression absence can be determined by the redistribution of factors in mitogenic and apoptotic cascades of the ras-signal-transducing pathway.

Nevertheless, presence of the DNA apoptotic degradation, i.e., the sign of the irreversible apoptotic death induction, is found after the GSSG•Pt action even in p21-defective cells.

The aforesaid allows us to state that the GSSG•Pt composite-based drug:

Realizes chemotherapeutic activity regarding the tumor-transformed cells through induction of the ras-dependent apoptotic pathway;

Induces the apoptosis' development in the tumor-transformed cells including p21-defective cells.

EXAMPLE 17

Therapeutical Effect of the GSSG•Pt Vanadium Salt in Patient with Diabetes Mellitus

Patient No. 7

Gender: female

Age: 37

Out-patient card: # 63

Diagnosis: Diabetes mellitus. Insulin-independent type—type II. Diabetic angiopathy, grade IV.

Anamnesis morbi: Firstly the high blood sugar was revealed in the age of 31. In October 1994, the patient was admitted into the Endocrinologic Department of the Hospital # 16. There were diabetes cases in the patient's hereditary history on the mother's side. The disease developed gradually, the blood glucose level fluctuated from 12.1 to 15.7 mmol/L, glucosuria to 7%.

Previous treatment: At the onset of the disease, the patient was frequently admitted to hospitals; in 1994 during six months she was administered with Insulin-lente S.N.C.-32 IU and peroral hypoglycemic agents of the sulfonylureas group; then Insulin was cancelled and the patient used antidiabetic agents—Bucarban, Diabeton. The blood glucose changed from 10.7 to 15.4 mmol/L, glucosuria 3-7%.

In January 1998 the patient was taken to the hospital and the following treatment regime was administered: Diabeton 0.08 g—2 tab twice a day, Glucobay 0.1×3 times per day.

The blood glucose content:

9.00  12.6 mmol/L
12.00 12.0 mmol/L
14.00 15.3 mmol/L
17.00 19.1 mmol/L
6.00  11.5 mmol/L

Glucosuria—to 3%.

Because of the previous treatment inefficacy, it was decided to use the drug of the GSSG•Pt vanadium salt.

Hospital Treatment Regime for the GSSG•Pt Vanadium Salt: From 17.01.98.

During 10 days once a day—intravenous injections of the GSSG•Pt vanadium salt (daily dose—0.01-0.5 mg/kg).

During the following 10 days—intravenous injections of the GSSG•Pt vanadium salt every other day (daily dose—0.01-0.5 mg/kg).

During the following 10 days (the third decade)—intramuscular injections of the GSSG•Pt vanadium salt once a day (daily dose—0.01-0.5 mg/kg).

The GSSG•Pt vanadium salt treatment was performed along with changed treatment regime by Diabeton and Glucobay. Diabeton was administered 0.08 twice a day, Glucobay 0.05×3 times a day.

The blood glucose restored to normal values and did not exceed 8.2-10.6 mmol/L after meals. After the discharge the patient received the GSSG•Pt vanadium salt treatment as an out-patient during one month.

Ambulant treatment regime for the GSSG•Pt vanadium salt:

For one month there were administered intramuscular injections of the GSSG•Pt vanadium salt once a day (daily dose—0.01-0.5 mg/kg).

During two sequential months of treatment with the GSSG•Pt vanadium salt drug there were noted two episodes of the glucose content decrease to 1.5-2.5 mmol/L, thereat the antidiabetic drugs dosages were lowered. After two months of the treatment, Glucobay was cancelled.

Patient's state after the treatment course completion: After four months of the treatment with administration of the GSSG•Pt vanadium salt drug as a support for the basic therapy, the patient's general state improved significantly and was evaluated as satisfactory. Development of hematologic, biochemical, immunologic blood indices is provided in the Tables 36, 37.

Comments to the indices development of glucose, cAMP/cGMP, thiol-disulfide ratio and other analyzed parameters.

The glucose content development is an integrative criterion for the impact effectiveness of the antidiabetic drugs. The combined therapy by the peroral antidiabetic drugs (Diabeton and Glucobay) along with the GSSG•Pt vanadium salt drug called forth the blood glucose normalization, decrease of the Diabeton therapeutic dosage and the Glucobay cancellation. Character of the hematologic, biochemical and immune parameter changes indicated restoration of the metabolism and the systemic reactions in general that does not allow to determine the antidiabetic constituent for the GSSG•Pt vanadium salt drug. The following indices were used—cAMP/cGMP and thiol-disulfide ratio (TDR)—that allowed to characterize basically a molecular mechanism of the GSSG•Pt vanadium salt drug action on cellular reaction complex stabilizing the blood glucose level. In particular, the key intracellular messengers—cAMP and cGMP—determine intensity of the glucose flow into intracellular metabolic processes. At that, cGMP-dependent enzymatic cellular systems determine the cellular glucose intake intensity. In its turn, the cGMP level is determined by the cellular oxidative potential. In particular, oxidants increase the cGMP level, in the contrary, antioxidants perform depressive action on its content. Thus, the intracellular thiol-disulfide ratio (TDR) reflecting the balance of the anti- and pro-oxidants determines value of the intracellular cAMP/cGMP index. Taking into account an organism as a whole we can analyze these indices in blood as integrative internal medium interrelated with the glucose level fluctuations, because the glucose metabolism is an indefeasible constituent for functioning of all cell types at our organism along with thiol-disulfide metabolism and cyclic nucleotide systems.

The results obtained indicated the glucose-lowering influence of the GSSG•Pt vanadium salt drug. Besides, this effect follows the cGMP content increase development (lowering of the cAMP/cGMP index) and the TDR value decrease (increase of the thiol oxidized forms). Considering regulatory possibilities of the thiol oxidized forms and the cGMP in blood glucose regulation, one can state the basic mechanism of the regulatory hypoglycemic effect of the GSSG•Pt vanadium salt drug. Inter alia, the regulatory impact of the GSSG•Pt vanadium salt drug on the cellular redox contour, provides an increase of the oxidant constituent level that, in its turn, redistributes balance in the cyclic nucleotide system in favor of cGMP (guanylat-cyclase induction and inhibition of phosphodiesterase, cGMP synthesis and destruction enzymes, respectively). The cGMP regulatory impact stimulates the glucose transport processes into insulin-dependent tissues calling forth the blood glucose decrease.

Conclusion: Application of the GSSG•Pt vanadium salt drug in the scheme for the combined diabetes treatment allowed to obtain the following therapeutic effects:

the quality of life improvement and the blood glucose level stabilization;

dosage decrease for the administered glucose-lowering drugs;

restoration to normal values of the hematologic, biochemical and immunologic indices.
