Pyridyl alkane acid amides as cytostatics and immunosuppressives

Abstract
The invention relates to new pyridyl alkane acid amides according to general formula (I) as well as methods for their production, medicaments containing these compounds as well as their medical use, especially in the treatment of tumors or for immunosuppression.
Description




The invention relates to new pyridine compounds, methods for their production, medicaments containing these compounds as well as their use, especially in the treatment of tumor conditions and/or as cytostatic agents or as immunosuppressive agents.




A strong need exists for the enrichment of cytostatic therapy to provide pharmaceuticals and/or medicaments which not only possess a strong activity, but also exert diminished side effects in comparison to many classical cancerostatic agents, whereby treatment of a broad as possible spectrum of tumors should be made accessible. Furthermore, effective cytostatic agents for an efficient therapy should be made available. Active ingredients of this type should also be exceptionally suitable in the mentioned indications for a combination therapy, be it in connection with other cytostatic agents or with radiation (for example X-rays, radioactive elements, such as cobalt, or linear accelerator, etc.), with operative procedures, heat treatment, etc.




In this connection, a strong need also exists to enrich tumor therapy with new compounds for overcoming or preventing resistances for example.




This object was successfully solved in a completely suprising manner by raking available the pyridyl alkane acid amide derivatives defined below.




It was known that various pyridine compounds substituted in a specific manner have pharmacologically useful properties which lie however in completely different indication areas.




Thus, ω-pyridyl alkane and/or alkene amides with anti-allergic activity are described in EP 0 210 782 which are referred to as having a 5-lipoxygenase-inhibiting and anti-histamine action, wherein the amide components of these compounds contain a piperizine or homopiperizine ring and the pyridine ring can be linked together in the 2-, 3- or 4-position. JP 63,179,869 describes further pyridyl amides, ωn-pyridyl alkane and alkene amides as anti-allergic effective substances containing a substituted piperidine ring in the amine component. Such compounds with the same properties are mentioned in Chem. Pharm. Bull 37, 100-105 (1989) and in J. Med. Chem. 1989, 583-593.




Pyridyl ureas, pyridyl thioureas and pyridyl carbonamides, wherein the amide portion is bound over an aryl substituted alkyl chain with a piperidine ring or piprazine ring, are described for example in EP-A-0 428 434 or in EP-A-0 512 902 as antagonists of the neurokinin receptor and subtance P. Furthermore, pyridyl(alkyl)carbonamides, pyridyl(alkyl)sulfonamides and analogous ureas, wherein the amide portion is bound over an alkyl chain with a piperidine ring are disclosed in EP-A-0 479 601 as active ingredients with anti-arrhythmic properties.




In WO 91/15 485, the production of pyridine-3,5-dicarboxylic acid esters and amides as well as their use for the treatment of tumor conditions is described. These compounds differ from the compounds according to the invention described below in very important structural features, for example by the dicarboxyl grouping on the pyridine ring or the absence of the hydrocarbon chain between the pyridine ring and the amide grouping. The compounds disclosed in WO 89/07 443 in the form of optically pure R(−)-Ni-guldipine and further analogous dihydropyridines with cytotoxic activity have larger structural differences. However, the compounds according to the invention unexpectedly possess a better activity and a wider spectrum of action despite the large structural differences.




Structurally closely related compounds are represented by the antagonists of the histimine-H


1


-receptor generally described in EP-A-0 343 307 which constitute substituted piperidine derivatives. However, no particular 3-pyridyl substitutions derivatives are concretely described in this publication.




In view of this art, the finding that the compounds according to the general formula (I) defined below have activities which make them particularly suitable in an excellent manner for the therapy of tumor illnesses was completely unexpected. Equally unexpected was the pharmacological finding that the compounds according to the invention also possess immunosuppressive properties besides cytostatic activity.




Pharmacological test results as well as the concrete tumor indications and combination possibilities are detailed and illustrated in the last part of the description.




Therefore, subject-matter of the invention relates to compounds of formula (I)

SYNTHESIS METHODS




Further subject-matter of the invention are analogous methods for the production of the compounds of formula (I) according to the invention.




Method (A):




Compounds of formula (I) are




(a) obtained by reacting carboxylic acids of formula (II)











 in which R


1


, R


2


, R


3


, A and k have the meaning described above or their reactive derivatives are reacted with compounds of formula (III)











wherein D, E, G and R


4


also have the above described meanings.




Reactive derivatives of compound (II) can be, for example, activated esters, anhydrides, acid halides (especially acid chlorides) or simple low alkyl esters. Suitable activated esters are, for example, p-nitrophenyl ester, 2,4,6-trichlorophenyl ester, pentachlorophenyl ester, cyanomethyl ester, esters of N-hydroxysuccinimide, of N-hydroxyphthalimides, of 1-hydroxybenzotriazol, of N-hydroxypiperidine, of 2-hydroxypyridine or of 2-mercaptopyridine, etc. Anhydrides can be symmetric anhydrides or mixed, as they are obtained, for example, with pivaloyl chloride or with chloroformates. Aromatic (for example chloroformic phenyl ester), araliphatic (for example chloroformic benzyl ester) or aliphatic chloroformates (for example chloroformic methyl ester, -ethyl ester or -isobutyl ester) can be used for this.




Reaction of compounds (II) with compounds (III) can also be carried out in the presence of condensation agents such as dicyclohexylcarbodiimide, 1-ethyl-3-(3-di-methylaminopropyl)carbodiimide hydrochloride, N,N′-carbonyldiimidazol, 1-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline, etc. If carbodiimides are used as the condensation agent, reagents such as N-hydroxysuccinimide, N-hydroxyphthalimide, 1-hydroxybenzotriazol, N-hydroxypiperidine, etc. can be advantageously added.




Compounds of formula (III) can be used for reaction as free bases as well as in the form of their acid addition salts. For this, the salts of inorganic acids are to be preferred, i.e. hydrochlorides, hydrobromides or sulfates.




Reaction of compounds (II) or their reactive derivatives with compounds (III) are normally carried out in a suitable, preferably inert solvent. As examples, aromatic hydrocarbons such as benzene, toluene, xylene, halogenated hydrocarbons (for example dichloromethane, chloroform, 1,2-dichloroethane, trichloroethylene), ether (for example diethyl ether, tetrahydrofuran, dioxane, glycol dimethyl ether), ethyl acetate, acetonitrile or polar aprotic solvents such as, for example, dimethylsulfoxide, dimethylformamide or N-methylpyrrolidone are to be named. Pure solvents, as well as mixtures of two or more, can be used.




The reaction is optionally carried out in the presence of an auxiliary base. Suitable examples for this are alkali metal carbonates (sodium carbonate, potassium carbonate), alkali metal hydrogen carbonates (sodium hydrogen carbonate, potassium hydrogen carbonate), or organic bases such as, for example, triethylamine, ethyl diisopropylamine, tributylamine, N-methylmorpholine or pyridine. A suitable excess of compound (III) can also be used as a base. If compounds (III) are used in form of their acid addition salts, then it is appropriate to consider the amount of auxiliary base used as equivalent.




The reaction temperatures can - depending on reactivity of the educts—vary in a wide range. Generally, the reaction is carried out at temperatures between −40° C. and 180° C., preferably between −10° C. and 130° C., especially at the boiling point of the solvent used.




The starting compounds (II) and (III) are known and/or can be produced according to known methods in an analogous manner. Moreover, the production of representative examples is further described below.




Compounds of formula (I) can be




(b) produced by reaction of compounds of formula (I), wherein G is hydrogen, and which themselves also have the activities found according to the invention, with a compound of formula (IV),






L—G  (IV)






in which G has the meaning given above, with the exception of hydrogen, and L represents a suitable nucleofuge or reactive group. The type of nucleofuge or reactive group L and the conditions of the reaction are dependent of the nature of group G.




Compounds of formula (I), in which G, with the exception of hydrogen, has the meaning of (G1) according to the above definition can, aside from method (a), also be (c) produced by reacting compounds of formula (I), in which G is hydrogen, with a suitable alkylation agent and/or arylation agent of formula (IV), wherein G is an alkyl-, alkenyl-, alkinyl-, cycloalkyl-, aryl-, aralkyl-, heteroaryl- or heteroaralkyl residue and the leaving group L can represent a reactive derivative of an alkohol, for example, a halogen atom such as chlorine, bromine or iodine or a sulfonic acid ester, i.e. for example a methanesulfonyloxy-, trifluoromethanesulfonyloxy-, ethanesulfonyloxy-, benzenesulfonyloxy-, p-toluenesulfonyloxy-, p-bromobenzenesulfonyloxy- or m-nitrobenzenesulfonyloxy residue, etc. or a reactive group L can also be an epoxide group, wherein the reaction occurs under addition.




The reaction of compounds (I), in which G is a hydrogen, and (IV) is usually conducted in a suitably inert solvent. As solvents of this type, aromatic hydrocarbons (benzene, toluene, xylene), ethers (for example tetrahydrofuran, dioxane, glycol dimethyl ether), ethyl acetate, acetonitrile, ketones (acetone, ethyl methyl ketone), polar protic solvents such as alcohols (ethanol, isopropanol, butanol, glycol monomethyl ether) or polar aprotic solvents such as, for example, dimethylsulfoxide, dimethylformamide or N-methylpyrrolidone can be considered. Pure solvents as well as mixtures of two or more can also be used. Preferably, the reactions are carried out in the presence of bases, whereby said bases can be used as in method (a) above. If chlorides or bromides are used as compound (IV), the reaction can be accelerated by the addition of alkali metal iodides (sodium iodide, potassium iodide). The reaction temperatures can vary between 0° C. and 180° C. depending on the reactivity of the educts, but preferably lie between 20° C. and 130° C.




Compounds of formula (I), in which G represents an acyl residue, a carbamoyl residue, a sulfonyl residue or a phosphinoyl residue according to the above definition, can also be produced, aside from the above method (a),




(d) by reacting compounds of formula (I), wherein G is hydrogen, with a carboxylic acid, carbamic acid, sulfonic acid and/or phosphinic acid of formula (V),




 HO—G  (V)




wherein G is an acyl residue, carbamoyl residue, sulfonyl residue or phosphinoyl residue according to definition, or their derivatives capable of reaction. Preferred derivatives of carboxylic acids and/or sulfonic acids (V) which are capable of reaction are symmetric or unsymmetric carboxylic acid anhydrides and/or sulfonic acid anhydrides or acyl- and/or sulfonyl halides, especially acyl- and/or sulfonyl chlorides. Preferably, derivatives of carbamates and/or phosphinic acids which are capable of reaction are the carbamoyl halides and/or phosphinyl halides, especially carbamyl- and/or phosphinyl chlorides. The reaction of the acids (V) and/or their reactive derivatives with compounds (I), in which G is hydrogen, preferably occurs in the presence of auxiliary bases in solvents and under conditions as they are described in method (a).




Compounds of formula (I), wherein G represents a carbamoyl residue according to the definition (G2b) with the proviso that r=0, the grouping is











can also be produced, aside from the methods (a) and (d)




(e) by reacting compounds of formula (I), in which G is hydrogen with a carbonyl group transmitter to an intermediate product and subsequently reacting this directly with a primary or secondary amine with the formula (VI)






H—NR


13


R


15


  (VI)






wherein R


13


and R


15


and/or the grouping —NR


13


R


15


have the meanings according to the above definitions without having to purify or isolate the intermediate product.




To-trichloromethyl carbonate (triphosgene) and carbonyldiimidazol have been proven as particularly reactive carbonyl group transmitters. The reaction of compounds of formula (I), wherein G is hydrogen, with triphosgene and/or carbonyldiimidazol are typically conducted in an absolute, inert solvent in the presence of a tertiary organic amine as an auxiliary base in such a manner that the solution of compounds (I) and the auxiliary base are slowly poured into a solution of an equivalent amount of carbonyl group transmitter. Thereby, the reaction requires molar ratios of 1:1 for the reaction of compound (I) and carbonyldiimidazol, and, in contrast, a ratio of 1:0.35 for the use of triphosgene. After complete reaction of the components to the intermediate product, compound (VI) is added in stochiometric amounts or in excess as a solution or a solid and the reaction is typically completed at elevated temperature. Suitable inert solvents are, for example hydrocarbons such as hexane, heptane, benzene, toluene, xylene, chlorinated hydrocarbons (for example dichloromethane, chloroform, 1,2-dichloroethane, trichloroethylene), ethers (for example diethyl ether, tetrahydrofuran, dioxane), esters such as ethyl acetate, butyl acetate, acetonitrile or polar aprodic solvents such as formamide or dimethylformamide. Pure solvents as well as mixtures can be used diversely. Sometimes it is of advantage to carry out the first partial reaction at low temperature in a low-viscosity, highly-volatile solvent and to remove the solvent after formation of the intermediate and replace it by a higher boiling solvent.




Amines such as for example triethylamine, ethyl diisopropylamine, tributylamine, N-methylmorpholine or pyridine are suitable as auxiliary bases. If compounds (I) or (VI) are used as salts, the amount of the auxiliary base is increased accordingly. The reaction temperatures can lie in between −40° C. and 50° C. for the first partial reaction, preferably at 0° C. to 30° C., and between 0° C. and 150° C. for the second partial reaction, preferably at 20° C. to 120° C.




Compounds of formula (I), wherein G represents a carbamoyl residue according to the definition (G2b) with the proviso that r=0 and R


15


=hydrogen, the grouping is











can also be produced, aside from methods (a), (d) and (e)




(f) by reacting the compounds of formula (I) in which G is hydrogen, with an isocyanate of formula (VII) in which R


13


has the meaning according to the above definition






O═C═N—R


13


  (VII).






Reaction of the compounds of formula (I), in which G is hydrogen, with the isocyanates of formula (VII) are conducted thereby in an absolute, inert solvent which can be a hydrocarbon such as pentane, hexane, heptane, benzene, toluene, or xylene, chlorinated hydrocarbons (such as dichloromethane, chloroform, 1,2-dichloroethane, trichloroethylene), ethers (for example, diethyl ether, tetrahydrofuran, dioxane), esters such as ethyl acetate, butyl acetate, or polar aprotic solvents such as formamide or dimethylformamide. Mixtures of various solvents can also be used. Thereby, the reaction temperatures can vary in the region from −20° C. to 150° C., but preferably lie at 20° C. to 100° C.




As already mentioned, the compounds of formula (I), wherein G is hydrogen, are themselves compounds with tumor growth inhibiting activity and/or cytostatic and immunosuppressive effectiveness. However, independent of their therapeutic applicability, they also represent useful intermediate compounds for the production of a multitude of other compounds according to the invention corresponding to (c) to (f).




They themselves can, in principle, be produced according to method A by reacting a carboxylic acid of formula (II) with amines of formula (III) in which G is hydrogen as described above. However, since the compounds of formula (III) with hydrogen as G represent α,ω-diamines, the formation of product mixtures is always to be expected in their reaction with carboxylic acids (II) or their reactive derivatives making a subsequent separation necessary.




In contrast, compounds of formula (I), in which G is hydrogen, are essentially more advantageously produced from other compounds of formula (I), in which G is a selectively cleavable group under mild conditions, i.e. corresponds to a nitrogen protective group.




Among the compounds according to formula (I) with tumor growth inhibiting and/or cytostatic or immunomodulatory and/or immunosuppressive properties, are compounds in which G represents a 4-methoxybenzyl group, a triphenylmethyl group, a methoxy- and/or ethoxycarbonyl group, a tert-butoxycarbonyl group, an allyloxycarbonyl group or a trifluoroacetyl group.




Thus, compounds of formula (I) with benzyl-, diphenylmethyl-, triphenylmethyl-, or benzyloxycarbonyl groups as G are already catalytically converted at room temperature under mild conditions with elementary hydrogen or by transfer hydration in compounds of formula (I), wherein G is hydrogen.




Compounds of formula (I) with a 4-methoxybenzyl group are transformed into compounds of formula (I) wherein G is hydrogen by selective oxidation with ammonium-cer(IV)-nitrate.




The cleavage of simple alkoxycarbonyl groups such as the methoxy- or ethoxycarbonyl group as well as the trifluoroacetyl group as G in compounds of formula (I) succeed by alkali hydrolysis under mild conditions without cleaving the A and D linked amide function. This is suitably valid for the cleavage of the triphenylmethyl group and the tert-butoxycarbonyl group as G in compounds of formula (I), which occurs in acidic medium under mild conditions. Finally, compounds of formula (I) with an allyloxycarbonyl group as G can be converted into such with hydrogen as G in neutral medium with palladium catalyst.




The described methods are fully familiar to the person skilled in the art and are furthermore also documented in monographs (see for example Greene, Wuts, Protective Groups in Organic Synthesis, New York, 1991).




Compounds of formula (I), wherein R


4


is an alkyl, alkenyl, alkinyl or cycloalkyl residue according to the above definition can also be produced, aside from the methods (a) and (b),




(g) by reacting compounds of formula (I), wherein R


4


is hydrogen, with a suitable alkylation agent of formula (VIII)






L—R


4


  (VIII)






wherein R


4


is an alkyl, alkenyl, alkinyl or cycloalkyl residue according to the above definition and L is a suitable nucleofuge, i.e. for example a halogen atom such as chlorine, bromine or iodine or a sulfonic acid ester of an alcohol. Preferred sulfonic acid esters (VIII) contain a methylsulfonyloxy residue, trifluoromethanesulfonyloxy-, p-toluenesulfonyloxy-, p-bromobenzenesulfonyloxy- or m-nitrobenzenesulfonyloxy residue as L.




As an amide alkylation in the presence of tertiary amino groups, this reaction requires the use of strong auxiliary bases such as potassium-tert-butylate, sodium hydride, potassium hydride or butyl lithium in aprotic, inert solvents. Such solvents can be for example aliphatic or aromatic hydrocarbons (pentane, hexane, heptane, benzene, toluene), ethers (for example, tetrahydrofuran, dioxane) or polar solvents such as dimethylsulfoxide, dimethylformamide or N-methylpyrrolidone. Depending on the reactivity of the educts, the reaction temperatures can lie between −40° C. and 140° C. preferably between −20° C. and 80° C.




The compounds of formula (I) produced according to the methods (a) to (g) can be isolated and purified in a known manner, for example by subjecting the residue after distillation of the solvent to partition, extraction, re-precipitation or re-crystallization or another purification method. For this, column chromatography on a suitable support or preparative, middle or high pressure liquid chromatography are preferred for this.




The compounds (I) are first normally obtained in form of their free bases or their hydrates or solvates, depending on the type of isolation and purification. Their addition salts with pharmaceutically suitable acids are obtained in a typical manner by converting the base with the desired acid in a suitable solvent. Depending on the number of basic centers of compound (I), one or more equivalent acids per mole of base can be bound.




Suitable solvents are, for example, chlorinated hydrocarbons such as dichloromethane or chloroform; ethers such as diethyl ether, dioxane or tetrahydrofuran; acetonitrile; ketones such as acetone or ethyl methyl ketone; esters such as methyl acetate or ethyl acetate or low molecular alcohols such as methanol, ethanol or isopropanol; and water. Pure solvents as well as mixtures of two or three solvents can also be used. The salts can be isolated by crystallization, precipitation or the evaporation of the solvent. Thereby, they optionally accumulate as hydrates or solvates.




The bases can be recovered from the salts by alkalization, for example with aqueous ammonia solution, alkali carbonate or diluted sodium hydroxide solution.




The following listed compounds and/or their pharmaceutically acceptable salts are particularly preferred.

2.47 g (16.3 mmol) 3-(3-pyridyl)-propionic acid are suspended in 40 ml absolute dichlormethane and cooled to ca. 0° C. in an ice bath under moisture exclusion after addition of three drops pyridine. 1.90 ml (22.3 mmol) oxalyl chloride are slowly added, and the mixture is first stirred for 30 min under ice cooling and then at RT overnight. Subsequently, the solvent and excess oxalyl chloride are distilled on a rotary evaporator. In order to completely remove the oxalyl chloride, the colorless residue is dried for two hours under high-vacuum. The acid chloride obtained in this manner is suspended in 50 ml absolute dichloromethane without further purification and cooled to ca. 0° C. in an ice bath under moisture exclusion. 5.0 g (14.8 mmol) 5-(1-diphenylmethyl-piperidin-4-yl)-pentylamine are dissolved in 40 ml absolute dichloromethane and added dropwise to this suspension. After complete addition, the ice bath is removed, and the reaction is stirred for two hours at RT. The mixture is subsequently concentrated, taken up in 10% sodium hydroxide solution and extracted three times with acetic acid ethyl ester. The combined organic phases are washed with saturated NaCl-solution, dried over sodium sulfate and the solvent is removed under vacuum.

The invention also relates to the use of the compounds according to formula (I) for treatment in the above indications.




The production of the respective suitable medicaments as well as a series of examples of medicinal forms are described in the following for better understanding of the invention.




Therapeutic Administration Forms




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 adjuvents 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 amono the most important systemically 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.




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, polyarnino 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 adjuvents such as for example gelatin, 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 sulfite and stabilizers, such as for example EDTA, are suitable as adjuvents 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 adjuvents, 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 gelatin 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 gelatin 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 gelatin capsules.




Anti-stick and lubricant and separating agents, dispersion agents such as flame dispersed silicone dioxide, disintegrants, 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 adjuvents for the production of compressives, such as for example tablets or hard and soft gelatin 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, aluminum stearate, calcium stearate, talc, siliconized talc, stearic acid, acetyl alcohol and hydrated fats are 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 tabs, both of which represent immediately drinkable instant medicinal forms which are quickly dissolved or suspended in water are among the perorally administratable compressives. Among the perorally administratable 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 inspisated 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 ingestable 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 gelatin or other carriers.




Hardened fat, such as for example Witepsol®, Massa Estarinum®, Novata®, coconut fat, glycerol-gelatin 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 systemically 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 adjuvents and carriers. Aside from suitable adjuvents 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 adminstration installation 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 adminstration 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 celluolose derivatives, such as for example guar or xanthene gum, inorganic gel builders, such as for example aluminum hydroxides or bentonites (so-called thixotropic gel builder), polyacrylic acid derivatives, such as for example Carbopol®R, polyvinylpyrolidone, microcrystalline cellulose or carboxymethylcellulose are suitable as adjuvents 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, sulfanated 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, Tris-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 aglomerates.




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 administeration 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 adjuvents, such as for example isopropyl myristate, polyoxyethylene sorbitan fatty acid ester, sorbitan trioleate, lecithins or soya lecithin.




For regional application in situ, solutions for installation, 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.

PHARMACEUTICAL EXPERIMENTAL SECTION




1. Growth Inhibition of Human Tumor Cells




The tumor growth inhibiting activity of the substances was determined on human tumor cells in standardized in vitro test systems. In the screening tests, the substances gave IC


50


-values in a concentration range of 0.1 nM to 10 μM.




Example




HepG2 cells plated at a density of 20,000 cells/ml in 12-well plastic dishes. Cultivation occurred in Richters IMEM-ZO nutrient medium with 5% fetal calf serum (FCS) in a tissue culture incubator with a gas mixture of 5% CO


2


and 95% air at a temperature of 37° C. One day after plating, the culture medium was aspirated from the cells and replaced by fresh medium which contained the respective concentrations of the test substance. For the individual concentrations and the controls without test substances, three-fold batch were done for each. Three days after the beginning of treatment, the medium was again renewed with the test compounds. After six days of substance incubation, the test was ended and the protein amount in the individual wells was determined with the sulforhodamin-B-method (according to P. Skehan et al.: New Colorimetric Cytotoxicity Assay for Anticancer-Drug Screening. J. Natl. Cancer Inst. 82: 1107-1112, 1990). The IC


50


-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.

2. Indications




The compounds of formula (I) and their salts permit a therapeutic use in malignant illness of human and animals through their excellent inhibition of the growth of tumor cells. The anti-neoplastic activity of the described substances can be used for prophylactic, adjunct, palliative, and curative treatment of solid tumors, leukemic illnesses and lymphomas as well as for decreasing or preventing metastasis formation in humans and animals. The therapeutic use is possible in the following illnesses for example: gynecological tumors, such as of the uterus or the vagina, ovarian carcinomas, testicle tumors, prostate carcinomas, skin cancer, kidney cancer, bladder tumors, esophagus carcinomas, stomach cancer, rectal carcinomas, pancreas carcinomas, thyroid cancer, adrenal tumors, leukemia and lymphomas, such as 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 leukemias. Thereby, benign papillomatosis tumors are also considered for therapy. The broad activity of the new compounds was tested in vitro on various human tumor cells. Thereby, the following IC

values were obtained for compound Nr. 54:

The novel structural class of compounds possesses an independent activity profile in the effectiveness against the various tumor types. Thus, tumors which are resistant to customary cytostatic agents, for example, respond entirely to these substances. In addition, based on the independent characteristics, combinations of the new compounds with known chemo-therapeutically used pharmaceuticals or other methods of treatment are considered, wherein their various properties are complimented in a suitable manner. The integration of the presently used compounds with their specific structures in a therapy scheme is successful with one or more substances from the following classes for example: anti-metabolites (for example cytarabine, 5-fluorouracil, 6-mercaptopurine, methotrexate), alkylating agents (for example busulfan, carmustine, cisplatin, carboplatin, cyclophosphamide, dacarbazine, melphalane, thiotepa), DNA-intercalating substances and topoisomerase inhibitors (for example actinomycin D, daunorubicin, doxorubicin, mitomycin C, mitoxantrone, etoposide, teniposide, topotecan, irinotecan), spindle poisons (for example vincristine, navelbin, taxol, taxoter), hormonally active agents (for example tamoxifen, flutamide, formestan, goserelin) or other cytostatic agents with complex modes of action (for example L-asparaginase, bleomycin, hydroxyurea). Resistant tumor cells can be made sensitive again by interaction of the new compounds with a mechanism of resistance for common cytostatic agents (for example P-glycoprotein, MRP, glutathione-S-transferase, metallothionein). A combination is also suitable with radiation therapy, hyperthermia or immunotherapy.




3. Immuno Suppressing Activity




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. Therefore, a use of the main compounds, optionally in combination with other compounds effective for these indications is suitable in diseases such as psoriasis or autoimmune diseases. In order to test the possibility for a therapeutic use in illnesses of this type, the substance activity 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% fetal 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% CO


2


. 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, IC


50


-values were calculated which were also employed in the following Tables for the characterization of the individual substances:

Furthermore, the independent class of the compounds used according to the invention also permits a combination with known immunosuppressive agents such as for example cyclosporin A, tacrolimus, rapamycin, azathioprin and glucocorticoids.




The invention is in no way limited to the present respective concretely named active ingredient concentrations, dosages, combinations with one or more other cytostatic agents, tumor inhibitors, cancerostatic agents, immunosuppressive agents or further medicinal agents suitable for the respective specific indications or the type of tumor to treated or immunological illness, etc.
