USE OF VITAMIN PP COMPOUNDS

The invention relates to the use of vitamin PP compounds (“PP”=pellagra preventing activity) and/or compounds with anti-pellagra activity such as, for example, nicotinic acid niacin), and nicotinamide (niacinamide, vitamin PP, vitamin B3) for the reduction, elimination or prevention of side-effects of different degrees of severity as well as for the neutralization of acute side-effects in immunosuppressive or cancerostatic chemotherapy or diagnostics, especially with substituted pyridine carboxamides as tumor inhibitors, optionally in combination with radiation therapy.

Nicotinamide is the most important building block for synthesis and maintenance of cellular stores of nicotinamide adenine dinucleotide (NAD). In gram amounts, it has a relatively low toxicity (Zackheim, Vasily, D. B. and Hastings C. W.: Reactions to niacinamide. J. Am. Acad. Dermatol. 4: 736-737, 1981), whereby its therapeutic priority in clinical use is to be seen in treatment of pellagra; see Green, R. G.: Subclinical pellagra: its diagnosis and treatment in Schizophrenia 2: 70-79, 1970. Nicotinamide was further used in order to cure the symptoms of schizophrenia Greenbaum, G. H. C.: An evaluation of niacinamide in the treatment of childhood schizophrenia or Am. J. Psychiatry 127: 89-92, 1970). Clinical tests for preventing type I diabetes mellitus have been undertaken; see Elliot, R. B. and Chase, H. P.: Prevention of delay of type I (insulin-dependent) diabetes mellitus in children using nicotinamide in Diabetologica 35: 362-365, (1991).

The NAD synthesized from nicotinic acid or nicotinamide i_simportant for the cellular production of adenosine triphosphate (ATP), the maintenance of the redox potential of cells and as a substrate for poly (ADP-ribose)-polymerase (PARP, EC 2.4.2.30) and the other reactions carried out by ADP-Ribose (Althaus, P. R. and Richter, C.: ADP-ribosylation of Proteins: Enzymology and Biological Significance, Springer Verlag, Berlin 1987). PARP is an enzyme which binds to DNA whose activity plays a role in DNA-repair, cell proliferation, apoptosis, cell differentiation and attending to the genome.

For some time, the administration of nicotinamide for increasing the sensitivity of tumors to chemotherapy and/or radiation therapy has been tested in pre-clinical and clinical studies (Kaanders, J. H. A. M., Pop, L. A. M., Marres, H. A. M., van der Maazen, R. W. M., van der Kogel, A. J. and van Daal, W. A. J.: Radiotherapy with carbogen and nicotinamide in head and neck cancer: feasibility and toxicity; Radiother. Oncol. 37: 190-198, 1995).

Two effects are discussed in the literature as a mechanism for the sensitizing properties of nicotinamide:

First, nicotinamide could lead to greater blood circulation through tumor tissue (Horsman, M. R., Chaplin, D. J. and Brown, J. M.: Tumor radiosensitization by nicotinamide: a result of improved blood perfusion and oxygenation. Rad. Res. 1181: 139-150, 1989; Chaplin, D. J., Horsman, M. R. and Aoki, D. S.: Nicotinamide, fluosol DA and carbogen: a strategy to reoxygenate acutely and chronically hypoxic cells in vivo; Br. J. Cancer 63: 109-113, 1991; Powell, M. E. B., Hill, S. A., Saunders, Hoskin, P. J. and Chaplin, D. J.: Human Tumor Blood Flow Is Enhanced by Nicotinamide and Carbogen Breathing. Cancer Research 57: 5261-5264, 1997). Hypoxic, under-supplied tumor cells could be stimulated to grow through better supply with oxygen (especially by the inhalation of high-percent oxygen/CO₂gas mixed carbogene) and nutrients which, in turn, would make them more susceptible to the actions of cytostatic agents and radiation.

Second, nicotinamide could cause an inhibition of the enzyme PARP, the latter playing a role in the repair of DNA damage as mentioned above. (Ben Hur, E., Utsumi, H. and Elkind, M. M.: Inhibitors of poly(ADP-ribose) synthesis enhance X-ray killing of log-phase chinese hamster cell in Radiat. Res. 97: 546-555, 1984; George, A. M., Lunec, J., Cramp, W. A., Brennan, S., Lewis, P. D. and Wish, W. J. D.: The effects of benzamide ADP-ribosyl transferase inhibitors on cell survival and DNA strand-break repair in irradiated mammalian cells in Int. J. Radiat. Biol. 49: 783-798, 1986). This enzyme uses the cellular pyridine nucleotide NAD as a substrate and transfers its ADP-ribose portion to other proteins whose function is regulated in this manner. Therewith, the DNA damage produced by cytostatic agents or radiation should lead more quickly to cell death by inhibition of PARP.

Previously, a series of medicaments have already been proposed for combating the considerable side-effects arising from cancerostatic chemotherapy such as, for example, dopamine antagonists, for example, chlorpromazine, droperidol, fluphenazine and other compounds, such as antihistamines such as, for example, buclizine, cyclizine, dimenhydrinate or promethazine. Benzquinamide and tronabinol or diphenidol or trimethobenzamide have also been used for this purpose for the therapy of side-effects of cancerostatic agents. However, massive side-effects can be ascribed to these medicinals themselves as is well-known by experts. These agents for the alleviation of side-effects such as, for example, haloperidol, methoclopramide, ondansetrone or domperidone are mainly used against severe nausea and vomiting caused by chemotherapy. Folic acid represents a very specific remedy which can only be administered in connection with methotrexate for reduction of its side-effects in the case of chemotherapeutic treatment.

Therefore, it is an object to find a method which helps to suppress neutralize or at least reduce, to a degree which is easy to bear for patients, the side-effects of different degrees of severity associated with chemotherapy, especially of tumors, or with the chemotherapeutic immunosuppression or with prevention of metastasis formation or anti-proliferative, treatment with pharmaceuticals.

A further object is also to entirely eliminate the side-effects which are already reduced in comparison to customary tumor inhibitors of the compounds according to the general formula (I), and, in individual cases, to still further diminish particular individual patient sensitivity.

Surprisingly, it has now been found that, in contrast to the effects and/or effectiveness-increasing activities of nicotinic acid or nicotinic acid amide in connection with radiation therapy discussed at the beginning, these compounds can be used for preventing side-effects or neutralizing the cell growth-inhibiting activity of cancerostatic and/or tumor-inhibiting chemotherapeutic agents based on an opposing effect which has not yet been explained scientifically.

In an unexpected manner, the inventors have now established that by using compounds with vitamin PP activity, side-effects of different degrees of severity which are associated with cancerostatic chemotherapy, for example, with the tumorstatic agents according to the general formula (I) can be reduced, eliminated or prevented. The use according to the invention and/or the medicaments according to the invention have the advantage that the compounds with vitamin PP activity used for the elimination of side-effects, especially according to the general formula (II) to (Vb), themselves do not cause new side-effects. This finding is surprising in view of the previous art in the field of cancerostatic chemotherapy. The unexpected effect could be traced back to a new biochemical mechanism of which no decisive clarity exists at the present time point.

Hence, the invention relates to the use of compounds with vitamin PP activity as a cyto-protective agents for the prevention, reduction or elimination of side-effects and/or neutralization of the effects of cancerostatic agents or immunosuppressive agents, especially of compounds from the series of substituted pyridylalkane, pyridylalkene and pyridylalkine acid amides of the general formula (I), in diagnostics or cytostatic or immunosuppressive chemotherapy, optionally in combination with radiation therapy.

Furthermore, it relates to the use of vitamins of the group PP as cyto-protective agents production of medicaments for prevention, reduction or elimination of side-effects and/or neutralization of the effects of cancerostatic agents or immunosuppressive agents, especially compounds from the series of substituted pyridylalkane, pyridylalkene and pyridylalkine acid amides in diagnostics or cytostatic, anti-proliferative or immunosuppressive chemotherapy, optionally in combination with radiation therapy. The use according to the invention in the application of compounds of the general formula (I) can also be in connection with their administration as an abortive agent.

Depending on the particular pharmacokinetics, for example, pH dependent pharmacokinetics, and particular metabolism, the named derivatives can have a prolonged effect optionally as a prodrug, or can be used topically, locally or regionally as a pharmaceutical with partially additional pharmacological effects such as increasing circulation, as analgesic agents or as morphine antagonists, especially in connection with the cancerostatic chemotherapy deployed according to the invention with the aim of neutralizing or decreasing side-effects.

A further particularly preferred embodiment of the invention is in the use of tryptophan as a vitamin PP precursor compound which is metabolized in vivo to a compound with vitamin PP activity (prodrug).

According to the a further particularly preferred embodiment according to the invention, one or more cancerostatic or immunosuppressive compounds different from the tumor inhibitors according to the general formula (I) is used in addition to the compound mixture comprising a cancerostatic agent, especially a compound according to the general formula (I), plus a compound with vitamin PP activity. This means that in the use according to the invention of vitamin PP compounds and/or the combinations according to the invention with an amount of these compounds, further cancerostatic agents, optionally alone, are considered in addition to the anti-tumor compounds especially those of the general formula (I), in cytostatic agents or immunosuppressive agents applied in chemotherapy in the form of the following compounds or compound groups:

Alkylizing, cytostatic agents (alkylanizers), for example derivatives without nitrogen such as cyclophosphamide, trofosfamide, ifosfamide, melphalane, mechloroethamine, chlorambucil as well as ethylenimine derivatives (aziridines) such as thiotepa. A further alkylizing compound would be for example busulfane. Additionally, among these exemplified alkylating cytostatic agents are carmustine, lomustine or nimustine, which can be considered in a wider sense as belonging to this compound group of alkylanizers as N-nitroso-urea derivatives. For example, procarbazine and dacarbazine also belong to these. Diaziquone, hexamethylmelamine, trimelamole or temozolamide are also referred to with respect to the series of alkylanizers. Examples for cancerostatic anti-metabolites are folic acid antagonists, such as methotrexate, edatrexate, trimetrexate or its ethyl derivative 10-ethyl-10-desaza-aminopterine as well as purine and pyrimidine base antagonists or antagonists with other points of attack, for example, 6-mercaptopurine and 6-thioguanine, 5-fluorouracil, floxuridine, ara-c, hydroxyurea, desoxycoformycine, triazofurine, acivicine, PALA, pyrazofurine as well as cytarabine, vidarabine, fludarabine, desoxycoformycine, 2-chloro-2′-desoxy-adenosine or tiazofurine.

In this connection, various IFN compounds, IL2 or leucovorine are particularly considered as synergists.

A further important group of cancerostatic agents are represented by the platinum complexes such as cisplatin and carboplatin. Podophyllotoxins or epipodophyllotoxins as antimitotic agents such as etoposide or teniposide have achieved certain importance as cancerostatic agents. This is true in a similar manner for vincaalkaloids, for example vinblastin, vincristin, vindesin, navelbin or 17-desacetylvinblastin.

Cytostatically effective antibiotics capable of being combined are also considered in connection with the invention such as, for example, actinomycins such as dactinomycin or actinoraycin D, anthracyclines such as daunorubicin, doxorubicin, rubidazone, detorubicin, epirubicin, carminomycin, aclacinomycin A, marcellomycin, AD-32, THP-doxorubicin, esorubicin, idarubicin, menogaril, or mitoxantrone or bleomycin as well as mitomycin C with comparable antibiotic effects. Morpholinyl derivatives with the name MRA, MRA-MO, MRA-CN or MRD-nr-CN or the morpholinyl anthracycline derivative MX2 also belong to these.

The series of the cancerostatic agents from different compound groups can be extended with newer compounds such as L-alanosine, amonafide, amsacrine, mafosfamide, bisantrene, carbethimer, desoxyspergualine, α-difluoromethylornithine, mitolactol, didemnine B, echinomycin, ellipticiniumacetate, gallium nitrate, optionally, cimetidine or retinoids, homoharringtonine, razoxane, indicin-N-oxide, lonidamine, menogaril, mitiguazone, N-methylformamide, mitozolamide, piritrexime, spirogermanium, spiromustin, suramin, taxol, taxoter, teroxirone, hydroxyurea, 1,2,4-triglyci-dylurazole, 1-asparaginase, lentinane, vinzolidine or radioactive isotopes such as ³²P, ⁹⁰Y, ²¹¹At or ¹³¹I, which can each be coupled to an antibody for targeting purposes.

An important group of cancerostatic agents are represented by hormonal compounds, i.e. hormones themselves such as androgens/anti-androgens, glucocorticoids or estrogens/anti-estrogens, depot estrogens, gestagens as well as hormone antagonists/hypothalamus hormones, estrogen receptor antagonists or aromatase inhibitors. Among others, examples of compounds of this type are mentioned in the following: busereline, gosereline, leuproreline, triptoreline, such as for example, stilbestrol, diethylstilbestrol, megestrol(acetate), diethyl-stilbestrol diphosphate, estradiol (undecylate), gonadoliberine, fosfestrol, estramustine, tamoxifene, drostanolone(propionate), fluoxymesterone, testolactone, aminoglutethimide, mitotane, medroxiprogesterone(acetate) flutamide, megestrol(acetate), aminoglutethimide, 4-hydroxyandrostendione, plumestane, exemestane, pyridoglutethimide, fadrazole, arimidex, vorazole, flutamide, cyproterone, mifepristone, hydroxyprogesterone, progesterone or ethinylestradiol,

For immunosuppressive therapies cyclosporine can be used for example, whereby corticosteroids, such as for example, prednisone or methylprednisolol as well as methotrexate and azathioprine or cyclophosphamide can also be applied. A known combination of immunosuppressive agents of this type is the combined use of cyclosporine or prednisone together with azathioprine.

Included in the series of the above customary, exemplified cancerostatic agents as well as cancerostatic agents not named here are pharmacolgically acceptable salts, esters, ethers, optic isomers, stereoisomers and other analogously effective derivatives depending on their structure.

The preferred single doses of the cancerostatic agents and/or immunosuppressive agents are oriented in accordance with customary therapeutic recommendations given in the literature and company information. Depending on effectiveness and the therapeutic spectrum of the cytcostatic agents, they range for example from 0.1 mg up to 10 000 mg. Expressed in absolute dosage units, the unit doses can be 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 75, 100, 150, 200, 300, 400, 500, 600, 750, 800, 900, 1000, in individual cases up to 1 200, 1 500, 2 000, 5 000 or 10 000 mg. In the case of the use of interferon compounds, the administered dosage amounts expressed in units are for example 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 40 or 50 million units. This is also true in a similar manner for cancerostatic enzymes, such as for example, asparaginases, which can be administered in an amount of 1000, 6000 or 10 000 units per m²body surface. The given dosage units also extend to the application of pyridylcarboxamide compounds according to the general formula (I), which can lie in the range between 0.1 mg, 1, 10 mg up to 5000 or 10 000 mg individual doses as discussed above. Depending on the existence of a synergistic, super-additive effect combination of two or more cancerostatic agents, the customary dosages can also be reduced. Therewith, the side-effects associated with the administration of cancerostatic agents can be further reduced. Conversely, if need be, considerably higher dose of cancerostatic agents can be administered without danger for patients in the case that the vitamin PP compounds reduce the side-effects in accordance with the invention.

The above discussion of the respective suitable cancerostatic agents merely has an exemplifying character and no limiting character in any way because it cannot be complete as a result of the incalculable abundance of known medicaments; further customary cancerostatic agents and carrier systems for this are to be taken from relevant handbooks such as for example M. Peckham, H. Pinedo and U. Veronesi: Oxford Textbook of Oncology Vol. 1 & Vol. 2, Oxford University Press, Oxford, N.Y., Tokyo (1995) or W. Forth, D. Henschler, W, Rummel, K. Starke: General and specific pharmacology, SPEKTRUM, Heidelberg, Berlin Oxford, 7. Edition (1996) or E. Mutschler: Medicament activities, textbook of pharmacology & toxicology, WVG, Stuttgart, 6. Edition (1991) or other compendia and the remaining literature or the art on anti-tumor agents.

In the use according to the invention, the dosage units of compounds of the general formula (I) respectively applied for the reduction, elimination or prevention of less severe side-effects lie in the range 5, 10, 20, 25, 30, 50, 75, 100, 200, 250, 300, 400, 500, 750 mg to 1000 mg and for eliminating a acute side-effects and/or neutralizing the cancerostatic agent effects lie in the range of 100, 250, 300, 500, 750 or 1000 up to 10 000 mg.

According to the invention, the above named medicaments can also be distinguished in that they contain one or more further cancerostatic or immunosuppressive compounds which are different from the compounds according to general formula (I) in addition to the cancerostatic agents, especially the tumor inhibitors according to the general formula (I).

In the above named indications, for example for reduction, elimination or prevention of less severe side-effects, the respective dosage units of compounds of the general formula (I) in the medicaments can be in the range of 5, 10, 20, 25, 30, 50, 100, 200, 250, 300, 500, 750, 1000 mg to 1000 mg and 100, 200, 250, 300, 500, 750 or 1000 to 10 000 mg for elimination of acute side-effects and/or for neutralization of cancerostatic agent effects.

Preferably, the medicaments are present in a solid, peroral administrable form as a table, capsule, coated tablet, optionally as a sustained action and/or gastric fluid-resistant preparation, or as a liquid medicinal form, for example as a respective, peroral administrable solution, suspension effervescent tablet, in the form of tabs or sachets optionally, in sustained action form and/or with protracted and/or accelerated or controlled release of the active ingredients. Preferably, the above named medicinal forms are used in connection with the application according to the invention.

Pursuant to a further preferred embodiment according to the invention, the medicaments are characterized in that the active ingredients combined with each other are contained separate from each other and/or in separate dosage units in the pharmaceutical package (kit-of-parts).

A further embodiment according to the invention relates to a medicament in the form of a suitable injection or infusion preparation together with suitable pharmaceutically acceptable carriers and adjuvants, optionally in sustained action form and/or as a parenteral depot form or implant or in the form of a concentrate, powder or lyophilisate, whereby the parenteral dilution agent can be optionally manufactured in the package separately therefrom such that the mixing of the compounds contained therein with the common parenterally applicable dilution agent is possible immediately before use.

Furthermore, the medicament can preferably be in the form of an inhalation therapeutic agent, for example, in the form of a spray together with suitable pharmaceutically acceptable propellants, carriers and adjuvants, whereby the pharmaceutically acceptable carrier and/or diluent can be an aerosol propellant.

Preferably, the medicament can also be present in the form of transdermal therapeutic system for systematic treatment. Moreover, it can also preferably be present in the form of a gastro-intestinal therapeutic system (GITS) for systematic treatment.

As a topical administrable medicament, it can preferably be formulated as a salve, suspension, emulsion, balm, or plaster or as an externally applicable solution.

Further preferred embodiments of the medicament used or produced according to the invention are in the application forms of dose aerosols, dry powder dosage formulations, rectal genital or transurethral administrable emulsions, solutions, liposomal solutions, implants, suppositories or capsules.

Therapeutic Administration Forms—Medicaments

The production of medicaments with an amount of one or more compounds according to the invention and/or their use in the application according to the invention occurs in the customary manner by means of common pharmaceutical technology methods. For this, the active ingredients as such or in the form of their salts are processed together with suitable, pharmaceutically acceptable adjuvants and carriers to medicinal forms suitable for the various indications and types of application. Thereby, the medicaments can be produced in such a manner that the respective desired release rate is obtained, for example a quick flooding and/or a sustained or depot effect.

Preparations for parenteral use, to which injections and infusions belong, are among the most important systematically employed medicaments for tumor treatment as well as for other indications.

Preferably, injections are administered for the treatment of tumors. These are prepared either in the form of vials or also as so-called ready-to-use injection preparations, for example as ready-to-use syringes or single use syringes in addition to perforation bottles for multiple withdrawals. Administration of the injection preparations can occur in the form of subcutaneous (s.c), intramuscular (i.m.), intravenous (i.v.) or intracutaneous (i.c.) application. The respective suitable injection forms can especially be produced as solutions, crystal suspensions, nanoparticular or colloid-disperse systems, such as for example, hydrosols.

The injectable formulations can also be produced as concentrates which can be adjusted with aqueous isotonic dilution agents to the desired active ingredient dosage. Furthermore, they can also be produced as powders, such as for example lyophilisates, which are then preferably dissolved or dispersed immediately before application with suitable diluents. The infusions can also be formulated in the form of isotonic solutions, fat emulsions, liposome formulations, microemulsions and liquids based on mixed micells, for example, based on phospholipids. As with injection preparations, infusion formulations can also be prepared in the form of concentrates to dilute. The injectable formulations can also be applied in the form of continuous infusions as in stationary as well as in out-patient therapy, for example in the form of mini-pumps.

Albumin, plasma expanders, surface active compounds, organic solvents, pH influencing compounds, complex forming compounds or polymeric compounds can be added to the parenteral medicinal forms, especially as substances for influencing the adsorption of the active ingredients to protein or polymers or also with the aim of decreasing the adsorption of the active ingredient to materials such as injection instruments or packaging materials, for example plastic or glass.

Depending on the chemical structure and binding capability, the cancerostatic agents can be used in the form of conjugates with albumin or compounds none convalently bound to albumin for example; see for this among others the publications U.S. Pat. No. 5,308,604, DE-A-195 14 087, DE-A-195 48 114, DE-A-196 02 295, DE-A-4 122 210, DE-A-4 433 890, DE-A-4 435 087, WO96/09071, WO96/25956, WO96/32134, PCT/DE/96/02487 or PCT/DE97/00166. Corresponding experiments were also undertaken with conjugates based on transferrin, cross-linked dextran, fibrinogen, casein or hemoglobin. Additionally, experiments to couple cancerostatics and/or their prodrugs with suitable antibodies used in tumor therapy seem to be promising. Combinations or monotherapies of this type with antibodies are therefore included within the present scope of the invention. Moreover, targeting experiments with albumin magnetically marked with magnetite (Fe³O⁴) were undertaken in order to enrich the tumor inhibitor in the form of so-called microballs (microspheres) in higher concentration at the place of action.

Carrier systems of this type are suitable as targeting transport media to enable a targeted delivery of the pharmaceutical to the target organ. In this manner, protection of healthy tissue can be better ensured, a greater enrichment of the active ingredient can be obtained, and, finally, better protection of cancerostatic agents sensitive against biological degradation can be obtained during the transport to the place of action. For these purposes, active ingredient liposomes can be produced in a known manner by means of coating and/or embedding methods by coating suitable carriers, whereby the active ingredients are encapsulated within membranes having a thickness down to the nanometer range. With respect to the art on liposomal compositions, reference is made here to U.S. Pat. No. 4,895,719 (=EP-A-0 223 831) and the publication WO-A-9 116 882 merely as representatives for many preparation methods.

There are numerous types of microballs (microspheres) or microparticles based on different adjuvants as carrier systems such as lipoproteins of low density (low density lipoproteins), activated charcoal particles, nanocapsules, nanoparticles, unilaminare or multilaminare vesicles (liposomes), polystyrol latex particles, microcapsules, whereby experiments with erythrocytes as a carrier medium were even carried out. For example polycyanoacrylates, polyacrylamide, gelatin based on cancerostatic agent/dextran conjugates, agarose, “ferromagnetic” ethylcellulose, poly(HEMA-BGA), carnauba wax, starch, vesicles of non-ionic tensides (niosomes), albumin/polyaspartic acid, phospholipids, viral sub-units (which lead to the formation of so-called virosomes) or polylactide (polylactic acid ester) are considered as carriers for microparticle systems of this type.

The active ingredients can be bound to nanoparticles in the preparations for parenteral use, for example on finely dispersed particles based on poly(meth)acrylates, polyacetates, polyglycolates, polyamino acids or polyether urethanes. The parenteral formulations can also be constructively modified as depot preparations, for example on the multiple unit principle, where the active ingredients are incorporated in a most finely distributed and/or dispersed, suspended form or as crystal suspensions, or on the single unit principle, where the active ingredient is enclosed in a medicinal form, for example, a tablet or a seed which is subsequently implanted. Often, these implantations or depot medicaments in single unit and multiple unit medicinal forms consist of so-called biodegradable polymers, such as for example, polyether urethanes of lactic and glycolic acid, polyether urethanes, polyamino acids, poly(meth)acrylates or polysaccharides.

Sterilized water, pH value influencing substances, such as for example organic and inorganic acids or bases as well as their salts, buffer substances for setting the pH value, agents for isotonicity, such as for example sodium chloride, monosodium carbonate, glucose and fructose, tensides and/or surface active substances and emulsifiers, such as for example, partial fatty acid esters of polyoxyethylene sorbitan (Tween®) or for example fatty acid esters of polyoxethylene (Cremophor®), fatty oils such as for example peanut oil, soybean oil and castor oil, synthetic fatty acid esters, such as for example ethyl oleate, isopropyl myristate and neutral oil (Miglyol®) as well as polymer adjuvants such as for example gelatine, dextran, polyvinylpyrrolidone, organic solvent additives which increase solubility, such as for example propylene glycol, ethanol, N,N-dimethylacetamide, propylene glycol or complex forming compounds such as for example citrates and urea, preservatives, such as for example hydroxypropyl benzoate and hydroxymethyl benzoate, benzyl alcohol, anti-oxidants, such as for example sodium sulphite and stabilizers, such as for example EDTA, are suitable as adjuvants and carriers in the production of preparations for parenteral use.

In suspensions, addition of thickening agents to prevent the settling of the active ingredients from tensides and peptizers, to secure the ability of the sediment to be shaken, or complex formers, such as EDTA, ensues. This can also be achieved with the various polymeric agent complexes, for example with polyethylene glycols, polystyrol, carboxymethylcellulose, Pluronics® or polyethylene glycol sorbitan fatty acid esters. The active ingredient can also be incorporated in liquid formulations in the form of inclusion compounds, for example with cyclodextrins. As further adjuvants, dispersion agents are also suitable. For production of lyophilisates, builders are also used, such as for example mannite, dextran, saccharose, human albumin, lactose, PVP or gelatine varieties.

As long as the active ingredients are not incorporated in the liquid medicinal formulations in the form of a base, they are used in the form of their acid addition salts, hydrates or solvates in the preparations for parenteral use.

A further systemic application form of importance is peroral administration as tablets, hard or soft gelatine capsules, coated tablets, powders, pellets, microcapsules, oblong compressives, granules, chewable tablets, lozenges, gums or sachets. These solid peroral administration forms can also be prepared as sustained action and/or depot systems. Among these are medicaments with an amount of one or more micronized active ingredients, diffusions and erosion forms based on matrices, for example by using fats, wax-like and/or polymeric compounds, or so-called reservoir systems. As a retarding agent and/or agent for controlled release, film or matrix forming substances, such as for example ethylcellulose, hydroxypropylmethylcellulose, poly(meth)acrylate derivatives (for example Eudragit®), hydroxypropylmethylcellulose phthalate are suitable in organic solutions as well as in the form of aqueous dispersions. In this connection, so-called bio-adhesive preparations are also to be named in which the increased retention time in the body is achieved by intensive contact with the mucus membranes of the body. An example of a bio-adhesive polymer is the group of Carbomers®.

For sublingual application, compressives, such as for example non-disintegrating tablets in oblong form of a suitable size with a slow release of active ingredient, are especially suitable. For purposes of a targeted release of active ingredients in the various sections of the gastrointestinal tract, mixtures of pellets which release at the various places are employable, for example mixtures of gastric fluid soluble and small intestine soluble and/or gastric fluid resistant and large intestine soluble pellets. The same goal of releasing at various sections of the gastrointestinal tract can also be conceived by suitably produced laminated tablets with a core, whereby the coating of the agent is quickly released in gastric fluid and the core of the agent is slowly released in the small intestine milieu. The goal of controlled release at various sections of the gastrointestinal tract can also be attained by multilayer tablets. The pellet mixtures with differentially released agent can be filled into hard gelatine capsules.

Anti-stick and lubricant and separating agents, dispersion agents such as flame dispersed silicone dioxide, disintegrates, such as various starch types, PVC, cellulose esters as granulating or retarding agents, such as for example wax-like and/or polymeric compounds on the basis of Eudragit®, cellulose or Cremophor® are used as a further adjuvants for the production of compressives, such as for example tablets or hard and soft gelatine capsules as well as coated tablets and granulates.

Anti-oxidants, sweetening agents, such as for example saccharose, xylite or mannite, masking flavors, aromatics, preservatives, colorants, buffer substances, direct tableting agents, such as for example microcrystalline cellulose, starch and starch hydrolysates (for example Celutab®), lactose, polyethylene glycols, polyvinylpyrrolidone and dicalcium phosphate, lubricants, fillers, such as lactose or starch, binding agents in the form of lactose, starch varieties, such as for example wheat or corn and/or rice starch, cellulose derivatives, for example methylcellulose, hydroxypropylcellulose or silica, talcum powder, stearates, such as for example magnesium stearate, aluminium stearate, calcium stearate, talc, siliconized talc, stearic acid, acetyl alcohol or hydrated fats, etc. are also used.

In this connection, oral therapeutic systems constructed especially on osmotic principles, such as for example GIT (gastrointestinal therapeutic system) or OROS (oral osmotic system), are also to be mentioned.

Effervescent tablets or tabsolute both of which represent immediately drinkable instant medicinal forms which are quickly dissolved or suspended in water are among the perorally administrable compressives.

Among the perorally administrable forms are also solutions, for example drops, juices and suspensions, which can be produced according to the above given method, and can still contain preservatives for increasing stability and optionally aromatics for reasons of easier intake, and colorants for better differentiation as well as antioxidants and/or vitamins and sweeteners such as sugar or artificial sweetening agents. This is also true for inspissated juices which are formulated with water before ingestion. Ion exchange resins in combination with one or more active ingredients are also to be mentioned for the production of liquid injectable forms.

A special release form consists in the preparation of so-called floating medicinal forms, for example based on tablets or pellets which develop gas after contact with body fluids and therefore float on the surface of the gastric fluid. Furthermore, so-called electronically controlled release systems can also be formulated by which active ingredient release can be selectively adjusted to individual needs.

A further group of systemic administration and also optionally topically effective medicinal forms are represented by rectally applicable medicaments. Among these are suppositories and enema formulations. The enema formulations can be prepared based on tablets with aqueous solvents for producing this administration form. Rectal capsules can also be made available based on gelatine or other carriers.

Hardened fat, such as for example Witepsol®, Massa Estarinum®, Novata®, coconut fat, glycerol-gelatine masses, glycerol-soap-gels and polyethylene glycols are suitable as suppository bases.

For long-term application with a systematic active ingredient release up to several weeks, pressed implants are suitable which are preferably formulated on the basis of so-called biodegradable polymers.

As a further important group of systematically active medicaments, transdermal systems are also to be emphasized which distinguish themselves, as with the above-mentioned rectal forms, by circumventing the liver circulation system and/or liver metabolism. These plasters can be especially prepared as transdermal systems which are capable of releasing the active ingredient in a controlled manner over longer or shorter time periods based on different layers and/or mixtures of suitable adjuvants and carriers. Aside from suitable adjuvants and carriers such as solvents and polymeric components, for example based on Eudragit®, membrane infiltration increasing substances and/or permeation promoters, such as for example oleic acid, Azone®, adipinic acid derivatives, ethanol, urea, propylglycol are suitable in the production of transdermal systems of this type for the purpose of improved and/or accelerated penetration.

As topically, locally or regionally administration medicaments, the following are suitable as special formulations: vaginally or genitally applicable emulsions, creams, foam tablets, depot implants, ovular or transurethral administration instillation solutions. For opthalmological application, highly sterile eye ointments, solutions and/or drops or creams and emulsions are suitable.

In the same manner, corresponding otological drops, ointments or creams can be designated for application to the ear. For both of the above-mentioned applications, the administration of semi-solid formulations, such as for example gels based on Carbopols® or other polymer compounds such as for example polyvinylpyrolidone and cellulose derivatives is also possible.

For customary application to the skin or also to the mucus membrane, normal emulsions, gels, ointments, creams or mixed phase and/or amphiphilic emulsion systems (oil/water-water/oil mixed phase) as well as liposomes and transfersomes can be named. Sodium algenate as a gel builder for production of a suitable foundation or cellulose derivatives, such as for example guar or xanthene gum, inorganic gel builders, such as for example aluminium hydroxides or bentonites (so-called thixotropic gel builder), polyacrylic acid derivatives, such as for example Carbopol®, polyvinylpyrolidone, microcrystalline cellulose or carboxymethylcellulose are suitable as adjuvants and/or Carriers. Furthermore, amphiphilic low and high molecular weight compounds as well as phospholipids are suitable. The gels can be present either as hydrogels based on water or as hydrophobic organogels, for example based on mixtures of low and high molecular paraffin hydrocarbons and Vaseline.

Anionic, cationic or neutral tensides can be employed as emulsifiers, for example alkalized soaps, methyl soaps, amine soaps, sulfonated compounds, cationic soaps, high fatty alcohols, partial fatty acid esters of sorbitan and polyoxyethylene sorbitan, for example lanette types, wool wax, lanolin, or other synthetic products for the production of oil/water and/or water/oil emulsions.

Hydrophilic organogels can be formulated, for example, on the basis of high molecular polyethylene glycols. These gel-like forms are washable. Vaseline, natural or synthetic waxes, fatty acids, fatty alcohols, fatty acid esters, for example as mono-, di-, or triglycerides, paraffin oil or vegetable oils, hardened castor oil or coconut oil, pig fat, synthetic fats, for example based on acrylic, caprinic, lauric and stearic acid, such as for example Softisan® or triglyceride mixtures such as Miglyol® are employed as lipids in the form of fat and/or oil and/or wax-like components for the production of ointments, creams or emulsions.

Osmotically effective acids and bases, such as for example hydrochloric acid, citric acid, sodium hydroxide solution, potassium hydroxide solution, monosodium carbonate, further buffer systems, such as for example citrate, phosphate, tries-buffer or triethanolamine are used for adjusting the pH value.

Preservatives, for example such as methyl- or propyl benzoate (parabenes) or sorbic acid can be added for increasing stability.

Pastes, powders or solutions are to be mentioned as further topically applicable forms. Pastes often contain lipophilic and hydrophilic auxiliary agents with very high amounts of fatty matter as a consistency-giving base.

Powders or topically applicable powders can contain for example starch varieties such as wheat or rice starch, flame dispersed silicon dioxide or silica, which also serve as diluents, for increasing flowability as well as lubricity as well as for preventing agglomerates.

Nose drops or nose sprays serve as nasal application forms. In this connection, nebulizers or nose creams or ointments can come to use.

Furthermore, nose spray or dry powder formulations as well as controlled dosage aerosols are also suitable for systemic administration of the active ingredients.

These pressure and/or controlled dosage aerosols and dry powder formulations can be inhaled and/or insufflated. Administration forms of this type also certainly have importance for direct, regional application in the lung or bronchi and larynx. Thereby, the dry powder compositions can be formulated for example as active ingredient-soft pellets, as an active ingredient-pellet mixture with suitable carriers, such as for example lactose and/or glucose. For inhalation or insufflation, common applicators are suitable which are suitable for the treatment of the nose, mouth and/or pharynx. The active ingredients can also be applied by means of an ultrasonic nebulizing device. As a propellant gas for aerosol spray formulations and/or controlled dosage aerosols, tetrafluoroethane or HFC 134a and/or heptafluoropropane or HFC 227 are suitable, wherein non-fluorinated hydrocarbons or other propellants which are gaseous at normal pressure and room temperature, such as for example propane, butane or dimethyl ether can be preferred. Instead of controlled dosage aerosols, propellant-free, manual pump systems can also be used.

The propellant gas aerosols can also suitably contain surface active adjuvants, such as for example isopropyl myristate, polyoxyethylene sorbitan fatty acid ester, sorbitan trioleate, lecithins or soya lecithin.

For regional application in situ, solutions for instillation, for example for transurethral administration in bladder tumors or genital tumors, or for profusion in liver tumors or other organ carcinomas are suitable.

The respective suitable medicinal forms can be produced in accordance with the prescription and procedures based on pharmaceutical-physical fundamentals as they are described for example in the following handbooks and are included in the present inventive subject-matter with respect to the production of the respective suitable medicaments:

1.4 Inhalation Therapeutic Agent

Further subject-matter of the use according to the invention are pharmaceutical formulations which are characterized in that they contain one or more cancerostatic agents used according to the invention as a base or a physiologically acceptable salt thereof together with carriers and/or diluents customary for this and suitable for administration by means of inhalation.

In this connection, particularly suitable physiologically acceptable salts of the active ingredients are, as already illustrated in the description section, acid addition salts derived from inorganic or organic acids such as for example especially hydrochloride, hydrobromide, sulfate, phosphate, maleate, tartrate, citrate, benzoate, 4-methoxybenzoate, 2- or 4-hydroxybenzoate, 4-chlorobenzoate, p-tosylate, methane sulfonate, ascorbate, salicylate, acetate, formate, succinate, lactate, glutarate, gluconate or tricarballylate. The administration of the cancerostatic agents used according to the invention by means of inhalation occurs in conventional ways customary for administrations of this type, for example in the form of a commercial controlled dosage aerosol or in combination with a spacer. In controlled dosage aerosols, a metering valve is delivered with whose help, a dosed amount of the composition is administered. For spraying, the present compositions can be formulated for example as aqueous solutions or suspensions and be administered by means of an atomizer. Aerosol spray formulations in which the active ingredient is either suspended with one or two stabilizers in a propellant as a carrier and/or diluent, for example tetrafluoroethane or HFC 134a and/or heptafluoropropane or HFC 227 can equally be used, whereby however, non-fluorinated hydrocarbons or other propellants which are gaseous at normal pressure and room temperature, such as propane, butane or dimethyl ether, can be preferred. Thereby, propellant-free manual pump systems or dry powder systems as described below can also be used.

Suitably, the propellant aerosols can also contain surface active adjuvants, such as for example isopropyl myristate, polyoxyethylene sorbitan fatty acid ester, sorbitan trioleate, lecithins, oleic acid.

For administration by means of inhalation and/or insufflation, the medicaments with an amount of compounds according to the invention can also be formulated in the form of dry powder compositions, for example as active ingredient-soft pellets or as an active ingredient-powder mixture with a suitable carrier, such as for example lactose and/or glucose. The powder compositions can be formulated and administered as single doses or as multiple doses.

The cancerostatic agent and/or tumor inhibitors according to the invention are preferably administered by means of a controlled dosage aerosol or in the form of a dry powder dosage formulation, wherein the latter preferably contains glucose and/or lactose as a carrier substance.

As applicators for inhalation of the pharmaceutical formulations containing one or more of the cancerostatic agents used according to the invention, all applicators are generally suitable which are suitable for controlled dosage aerosols and/or a dry powder dosage formulation, such as for example usual applicators for the nose, mouth and or pharynx, or also devices standing under propellant gas for the delivery of a spray (as controlled dosage aerosol or dry powder dosage formulation) as they are also used for inhalations in the nose, mouth and/or pharynx.

A further embodiment can also consist of an aqueous solution of the cancerostatic agents considered which also optionally contains further active ingredients and/or additives that are applied by means of an ultrasound atomizer.

The corresponding suspension is dispersed by means of a suitable stirring system (for example high performance mixer or ultrasound mixer) until an ultra-fine dispersion results. The suspension is then continuously held in flux in a filling apparatus suitable for cold propellants or pressure fillings. Alternatively, the suspension can also be produced in a suitable cooled stabilizer solution in HFC 134a/227.

E. Combination of Different Tumor Inhibitors and/or Cytostatic Agents or Cancerostatic Agents with the Vitamin PP Compounds

As already mentioned above, further cancerostatic agents, optionally as sole cytostatic agents or immunosuppressive agents for example in the form of the following compounds or compound groups can be formulated, in addition to the anti-tumor compounds especially those of the general formula (I) into the above given examples for the use of the vitamin PP compounds according to the invention and/or the combinations according to the invention with an amount of these compounds:

Alkylizing, cytostatic agents (alkylanizers), for example, derivatives without nitrogen such as cyclophosphamide, trofosfamide, ifosfamide, melphalane, mechloroethamine, chlorambucil as well as ethylenimine derivatives (aziridines) such as thiotepa; further alkylizing compound would be for example busulfane; additionally, among these exemplified alkylating cytostatic agents are carmustine, lomustine or nimustine, which can be considered in a wider sense as belonging to this compound group of alkylanizers as N-nitroso-urea derivatives; procarbazine and dacarbazine are also mentioned as belonging to this series; diaziquone, hexamethylmelamine, trimelamole or temozolamide are also referred to with respect to the group of alkanizers.

Examples for cancerostatic anti-metabolites are folic acid antagonists, such as methotrexate, edatrexate, trimetrexate or its ethyl derivative 10-ethyl-10-desaza-aminopterine as well as purine and pyrimidine base antagonists or antagonists with other points of attack, for example, 6-mercaptopurine and 6-thioguanine, 5-fluorouracil, floxuridine, ara-c, hydroxyurea, desoxycoformycine, triazofurine, acivicine, PALA, pyrazofurine as well as cytarabine, vidarabine, fludarabine, desoxycoformycine, 2-chloro-2′-desoxy-adenosine or tiazofurine.

In this connection, various IFN compounds, IL2 or leucovorine are particularly considered as synergists.

A further important group of cancerostatic agents are represented by the platinum complexes such as cisplatin and carboplatin. Podophyllotoxins or epipodophyllotoxins as antimitotic agents such as etoposide or teniposide have achieved certain importance as cancerostatic agents. This is true in a similar manner for vinca alkaloids, for example vinblastin, vincristin, vindesin, navelbin or 17-desacetylvinblastin.

Cytostatically effective antibiotics capable of being combined are also considered in connection with the invention such as, for example, actinomycins, such as dactinomycin or actinomycin D, anthracyclines such as daunorubicin, doxorubicin, rubidazone, detorubicin, epirubicin, carminomycin, aclacinomycin A, marcellomycin, AD-32, THP-doxorubicin, esorubicin, idarubicin, menogaril, or mitoxantrone or bleomycin as well as mitomycin C with comparable antibiotic effects. Morpholinyl derivatives with the name MRA, MFA-MO, MRA-CN or MRD-nr-CN or the morpholinyl anthracycline derivative MX2 also belong to these.

The series of the cancerostatic agents from different compound groups can be extended with newer compounds such as L-alanosine, amonafide, amsacrine, mafosfamide, bisantrene, carbethimer, desoxyspergualine, α-difluoromethylornithine, mitolactol, didemnine B, echinomycin, ellipticiniumacetate, gallium nitrate, optionally, cimetidine or retinoids, homoharringtonine, razoxane, indicin-N-oxide, lonidamine, menogaril, mitiguazone, N-methylformamide, mitozolamide, piritrexime, spirogermanium, spiromustin, suramin, taxol, taxoter, teroxirone, hydroxyurea, 1,2,4-triglycidylurazole, 1-asparaginase, lentinane, vinzolidine or radioactive isotopes such as ³²P, ⁹⁰Y, ²¹¹At or ¹³¹I, which can each be coupled to an antibody for targeting purposes.

An important group of cancerostatic agents are represented by hormonal compounds, i.e. hormones themselves such as androgens/anti-androgens, glucocorticoids or estrogens/anti-estrogens, depot estrogens, gestagens as well as hormone antagonists/hypothalamus hormones, estrogen receptor antagonists or aromatase inhibitors. Among others, examples of compounds of this type are mentioned in the following: busereline, gosereline, leuproreline, triptoreline, such as for example, stilbestrol, diethylstilbestrol, megestrol(acetate), diethyl-stilbestrol diphosphate, estradiol(undecylate), gonadoliberine, fosfestrol, estramustine, tamoxifene, drostanolone(propionate), fluoxymesterone, testolactone, aminoglutethimide, mitotane, medroxiprogesterone(acetate) flutamide, megestrol(acetate), aminoglutethimide, 4-hydroxyandrostendione, plumestane, exemestane, pyridoglutethimide, fadrazole, arimidex, vorazole, flutamide, cyproterone, mifepristone, hydroxyprogesterone, progesterone or ethinylestradiol, For immunosuppressive therapies cyclosporin can be used for example, whereby corticosteroids, such as for example, prednisone or methylprednisolol as well as methotrexate and azathioprine or cyclophosphamide can also be applied. A known combination of immunsuppressive agents of this type is the combined use of cyclosporine or prednisone together with azathioprine.

The preferred single doses of the cancerostatic agents and/or immunosupressive agents are oriented in accordance with customary therapeutic recommendations given in the literature and company information. Depending on effectiveness and the therapeutic spectrum of the cytcostatic agents, they range for example from 0.1 mg up to 10 000 mg. Expressed in absolute dosage units, the unit doses can be 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 75, 100, 150, 200, 300, 400, 500, 600, 750, 800, 900, 1000, in individual cases up to 1 200, 1 500, 2 000, 5 000 or 10 000 mg. In the case of the use of interferon compounds, the administered dosage amounts expressed in units are for example 1, 2, 3, 4, 5, 10, 15, 20, 25, 30 40 or 50 million units. This is also true in a similar manner for cancerostatic enzymes, such as for example, asparaginases, which can be administered in an amount of 1000, 6000 or 10 000 units per m²body surface. The given dosage units also extend to the application of pyridylcarboxamide compounds according to the general formula (I), which can lie in the range between 0.1 mg, 1, 10 mg up to 5000 or 10 000 mg individual doses as discussed above. Depending on the existence of a synergistic, super-additive effect combination of two or more cancerostatic agents, the customary dosages can also be reduced. Therewith, the side-effects associated with the administration of cancerostatic agents can be further reduced. Conversely, if need be, considerably higher dose of cancerostatic agents can be administered without danger for patients in the case that the vitamin PP compounds reduce the side-effects in accordance with the invention.

The above discussion of the respective suitable cancerostatic agents merely has an exemplifying character and no limiting character in any way because it cannot be complete as a result of the incalculable abundance of known medicaments; further customary cancerostatic agents and carrier systems for this are to be taken from relevant handbooks such as for example M. Peckham, H. Pinedo and U. Veronesi: Oxford Textbook of Oncology Vol. 1 & Vol. 2, Oxford University Press, Oxford, N.Y., Tokyo (1995) or W. Forth, D. Henschler, W. Rummel, K. Starke: General and specific pharmacology, SPEKTRUM, Heidelberg, Berlin Oxford, 7. Edition (1996) or E. Mutschler: Medicament activities, textbook of pharmacology & toxicology, WVG, Stuttgart, 6. Edition (1991) or other compendia and the remaining literature or the art on anti-tumor agents.

Pharmacological
Experimental Portion

In the following examples, an anti-tumor substance was used which was synthesized by Klinge Pharma GmbH under the label K22.097 and is described in the publication PCT/EP97/03243=WO97/48695 as substance Nr.54 (production example 4 in the form of N-[4-(1-diphenylmethylpiperidin-4-yl)-butyl]-3-(pyridin-3-yl)-propionamide.

1. Neutralization of the Growth-Inhibiting Effect of Anti-Tumor Substances by Nicotinic Acid and Nicotinamide in Human Leukaemia Cells.

THP-1 cells derived from a human monocytic leukaemia plated at a density of 200,000 cells/ml in 96-well plastic dishes. Cultivation occurred in RPMI 1640 nutrient medium with 10% foetal calf serum (FCS) in a tissue culture incubator with a gas mixture of 5% CO₂and 95% air at a temperature of 37° C. For the individual concentrations and the controls without test substances as well as for the background with nutrient medium but without cells, three-fold batches were done for each. After four days of substance incubation 20 μl WST-1 reagent (Boehringer Mannheim) was respectfully pipetted in each individual well. After 30 to 60 minute incubation in the tissue culture incubator at 37° C. and 5% CO₂, the light extinction was measured in an ELISA reader at 450 nm wave length. The backgrounds were each subtracted from the typical measured valves. (The IC₅₀-values (defined as that concentration in which the cell growth was inhibited by 50%) was taken from the dose-response curves and given as a comparative measurement for the activity of the test compounds.

The measured values obtained in this manner are given in the following Table 1:

As can be seen from Table 1, the growth-inhibiting effect of K22.097 is abrogated by nicotinic acid as well as by nicotinamide.

2. Neutralization of the Growth-Inhibiting Effect of Anti-Tumor Substances by Nicotinic Acid and Nicotinamide in Normal Lymphocytes

Many cytostatic agents and radiation therapies as well have a cytcotoxic effect not only on tumor cells but also on the blood cell system. This leads to a weakening of the immune defence which can lead to life threatening infections. In addition, this can result in a so-called tumor lyse syndrome which can, lead to the death of the patient by the relatively quick death of large cell masses. In order to test the possibility for a therapeutical use of nicotinic acid and/or nicotinamide for preventing such life threatening conditions by massive cell death, the effect of the substance was tested on freshly isolated lymphocytes as follows:

The spleen of a Swiss mouse served as a lymphocyte source.

The lymphocyte population was isolated from the spleen cell suspension over a ficoll gradient and taken up in IMEM-ZO culture medium with 0,1% dextran 70,000 and 2% foetal calf serum. The cells were plated at a density of ca. 500,000 cells/well/ml in a 12-well plate, 1 ml doubly concentrated test substance solution was pipetted per well and this was subsequently incubated in a tissue culture incubator at 37° C. and 5% CO₂. After 2 days, a 1 ml-aliquot with 5 μl of the fluorescent dye solutions propidium iodide (8 mg/ml) and 3,3′-dihexyloxacarbocyanin iodide (40 μg/ml) each was added per well, and incubated for 3 minutes at room temperature. Subsequently, 10,000 cells per each sample were measured on a flow-through cytometer and the percentage amount of vital cells in the population was determined. By means of the dose-response curves, IC₅₀-values were calculated which were also employed in the following Tables for the characterization of the individual substances:

3. Neutralization of Growth-Inhibiting Effect of Anti-Tumor Substances by Nicotinic Acid in Nicotinamide in Primary Intestine Cells.

Cryptic cells of the large intestine were isolated according to the method of Booth et al. (1995) with slight modifications. The removed large intestine was cut into pieces, the parts were finally cut after several-fold washing and digested with collagenase and dispase. Subsequently, the larger tissue pieces remaining in the suspension were sedimented, the supernatant was decanted and stored. The pellet was digested again under vigorous shaking with medium in order to release additional cryptic cells. After sedimentation, the supernatant was poured off again, combined with the first fraction and the cryptic cells were centrifuged at 50×g. After a further washing step, the centrifuge cryptic cells were suspended in culture medium and seeded at a density of 800 cells per well in 24-well-cultured dishes which were previously coated with collagen. The cells were incubated at 37° C. in a saturated water vapour atmosphere with 92.5% air and 7.5% CO₂. 50% of the nutrient medium was renewed every two days. The test substances were added 48 hours after the plating of the cryptic cells; the treatment with them lasted a total of 4 days.

The growth of the culture was photometrically quantified after staining with crystal violet as a measure for the cell number and the vitality of the cells was determined with the MTT-test whose reaction depends on living cells with active mitochondria. Based on dose response curves, the IC₅₀-values were calculated which are also used in the following Table 3 for characterization of the individual substance activity:

4. Neutralization of the Toxic Effect of Anti-Tumor Substances by Nicotinamide in NMRI Mice

Groups of 6 mice each were treated over 4 days with different doses of the anti-tumor substance K22.097 orally administered twice daily. Parallel to this, 500 mg/kg nicotinamide was simultaneously intraperitoneally administered each to the individual dosage groups. 7 days after the beginning of treatment, the blood picture of the individual animals was examined. The results are summarized in following Table 4:

The results of Table 4 show that the cases of death caused by the anti-tumor substance as well as the strong reduction of leucocyte cells could be completely prevented.

It is evident from the experimental results represented in Tables 1-4 that the use of compounds of the vitamin PP group according to the invention is capable of suppressing the unavoidable side-effects of anti-tumor substances or is at least capable of elevating these and/or neutralizing the cancerostatic activity in a surprising manner in unexpected threatening incidents. This result was not to be expected in view of the known, sensitivity-increasing and effect-increasing activities of nicotinic acid and/or its amide discussed at the beginning.

As already discussed in the above mentioned publications and also the older patent applications of the applicant not yet published at the present application date, the tumorstatic agents according to the general formula (I) are especially suitable also in connection with the invention subject matter described herein, preferably in the chemotherapy of malignant diseases of humans and animals. The anti-neoplastic effect of the described substances of formula (I) can be used for prophylactic, adjuvant, palliative and curative treatment of solid tumors, leukeamic diseases and lymphomas, as well as for reducing or preventing metastases formation in humans and animals. The therapeutic use is possible in the following illnesses for example: gynaecological tumors, ovarian carcinomas, testicle tumors, prostate carcinomas, skin cancer, kidney cancer, bladder tumors, oesophagus carcinomas, stomach cancer, rectal carcinomas, pancreas carcinomas, thyroid cancer, adrenal tumors, leukaemia and lymphomas, Hodgkin's disease, tumor illnesses of the CNS, soft-tissue sarcomas, bone sarcomas, benign and malignant mesotheliomas, but especially intestine cancer, liver cancer, breast cancer, bronchial and lung carcinomas, melanomas, acute and chronic leukaemias. Benign papillomatosis tumors can also be limited in their growth with the named substances.

The use according to the invention and the medicaments according to the invention for neutralization of acute side-effects or reduction of side-effects can also be performed with these substances according to general formula (I) in tumors which are resistant against customary cytostatic agents. In addition, as already mentioned above, combinations of these tumor inhibitors with other known pharmaceutical agents which are used in chemotherapy are promising due to their independent characteristics as long as their properties are complemented in a suitable manner.

The integration of these pyridylcarboxamides in a therapy scheme can be particularly successful for example with one or more substances from the following classes:

anti-metabolites (for example cytarabine, 5-fluorouracil, 6-mercaptopurine, methotrexate), alkylating agents (for example busulfane, carmustine, cisplatin, carboplatin, cyclophosphamide, dacarbazine, melphalane, thiotepa), DNA-intercalating substances and topoisomerase inhibitors (for example actinomycin D, daunorubicin, doxorubicin, mitomycin C, mitoxantrone, etoposide, teniposide, topotecane, irinotecane), spindle poisons (for example vincristine, nayelbine, taxol, taxoter), hormonally active agents (for example tamoxifene, flutamide, formestane, gosereline) or other cytostatic agents with complex modes of action (for example L-asparaginase, bleomycin, hydroxyurea). Resistant tumor cells can be made sensitive again for example by interaction of the new compounds with a mechanism of resistance for common cytostatic agents (for example P-glycoprotein, MRP, glutathione-S-transferase, metallothionein).

Many anti-tumor agents have not only a cytotoxic effect on tumor cells, but also on the blood cell system. This leads to a weakening of the immune defence, which can, in turn, be specifically employed to suppress the rejection reaction after an organ transplantation for example. The use in immunological disease such as for example psoriasis or autoimmune diseases is therefore also possible. Hence, the independent structural class of the preferred compounds from the group of substituted 3-pyridylcarboxyl amides also makes possible a combination with other known immunosuppressive agents such as for example, cyclosporine A, tacrolimus, rapamycin, azathioprine and glucocorticoids.

Furthermore, the anti-tumor substance Nr.159 with the internal label K22.175 according to the publication PCT/EP97/03245=WO97/48696 in the form of N-[4-(1-benzoylpiperidin-4-yl)-butyl]-3-(pyridin-3-yl)-acrylamide synthesized by the applicant was included in the experimental examinations. The results obtained therefrom confirm the above described finding on the useful effect according to the invention of the vitamin PP compounds. The results corresponding to the method used in Example 1, Table 1, are given in Table 5 as follows:

As already mentioned at the beginning, the use according to the invention and the medicaments produced and applied according to the invention also relate to the combination of cancerostatic chemotherapy with radiation and/or radiotherapy, whereby hypothermia as a heat irradiation treatment or other physical tumor therapies are included within the invention.
