Sulfonamido- and sulfonamidocarbonylpyridine-2-carboxamides and their pyridine-n-oxides, process for their preparation and their use as pharmaceuticals

The invention relates to sulfonylamino- or sulfonylaminocarbonyl carbonylpyridine-2-carboxamides and their pyridine-N-oxides, and to their use as pharmaceuticals against fibrotic diseases.
Compounds which inhibit the enzymes proline hydroxylase and lysine hydroxylase, effect very selective inhibition of collagen biosynthesis by affecting the collagen-specific hydroxylation reactions. In the course thereof, protein-bound proline or lysine is hydroxylated by the enzymes proline hydroxylase or lysine hydroxylase. If this reaction is suppressed by inhibitors, an under-hydroxylated collagen molecule which is not capable of functioning is formed, which can be released into the extracellular space by the cells only in a small amount. The underhydroxylated collagen can additionally not be incorporated into the collagen matrix and is very easily degraded proteolytically. As a result of these effects, the total amount of extracellularly deposited collagen is reduced.
Inhibitors of proline hydroxylase are therefore suitable substances in the therapy of diseases in which the deposition of collagens decisively contributes to the clinical picture. These include, inter alia, fibroses of the lungs, liver and skin (scleroderma) and atherosclerosis.
It is known that the enzyme proline hydroxylase is effectively inhibited by pyridine-2,4- and -2,5-dicarboxylic acid (K. Majamaa et al., Eur. J. Biochem. 138 (1984) 239-245). However, these compounds are only effective as inhibitors in cell culture at very high concentrations (Tschank, G. et al., Biochem. J. 238 (1987) 625-633).
DE-A 3,432,094 describes pyridine-2,4- and -2,5-dicarboxylic acid diesters having 1-6 carbon atoms in the ester alkyl moiety as pharmaceuticals for the inhibition of proline hydroxylase and lysine hydroxylase.
However, these lower alkyl diesters have the disadvantage that they are cleaved too rapidly in the body to give the acids and do not reach their site of action in the cell in sufficiently high concentration and are thus less suitable for possible administration as pharmaceuticals.
DE-A 3,703,959, DE-A 3,703,962 and DE-A 3,703,963 described in general form mixed esters/amides, and higher alkyl diesters and diamides of pyridine-2,4- and -2,5-dicarboxylic acid which effectively inhibit collagen biosynthesis in the animal model.
The object, then, was to seek compounds which are more strongly antifibrotic than the compounds known to date.

The invention furthermore relates to the use of compounds of the formula I and the physiologically tolerable salts for the production of a pharmaceutical against fibrotic diseases, in particular of the liver.
Finally, the invention relates to the compounds of the formula I for use as pharmaceuticals.
The invention relates in particular to the compounds of the formula I for use as fibrosuppressants.
The invention furthermore relates to a process for the preparation of compounds of the formula I.
Compounds of the formula I in which X is a single bond were prepared by
i) reacting the pyridine-2-carboxylic acid ester derivatives of the formula 3 or the pyridine-2-carboxylic acid derivatives of the formula 4 with the amines of the formula 5, or
ii) reacting the pyridine-2-carboxamide derivatives of the formula 6 with the sulfonic acid derivatives of the formula 2, cf. Scheme 1.
Scheme 1 illustrates the preparation of compounds of the formula Ia or Ib, in which X is a single bond: ##STR3##
5-Aminopyridine-2-carboxylates of the formula 1 are reacted with sulfonic acid derivatives or carboxylic acid derivatives of the formula 2, in which Z is a hydroxy group or a leaving group which can be detached nucleophilically and is in particular F, Cl, Br, I or tosylate. This reaction is carried out in an aprotic organic solvent or a solvent mixture. The following solvents may be mentioned in particular: dichloromethane, tetrachloromethane, butyl acetate, ethyl acetate, toluene, tetrahydrofuran, dimethoxyethane, 1,4-dioxane, acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, nitromethane and/or pyridine, if appropriate with the addition of an acid binder, such as ammonia, triethylamine or tributylamine, at a reaction temperature from 0.degree. to 180.degree. C., preferably from 0.degree. to 180.degree. C. If Z is a hydroxy group, the condensation methods known from peptide chemistry are suitable.
The compounds of the formula Ia are finally either obtained by hydrolyzing the compounds of the formula 3 to give the pyridine-2-carboxylic acids 4 and reacting these with the appropriate amines 5 according to the known methods of peptide chemistry or by reacting the compounds of the formula 3 directly with the amines 5. If desired, oxidation to give the pyridine-N-oxides of the formula Ib is additionally carried out immediately afterwards.
A general procedure for this oxidation method is also described, for example, in "E. Klinsberg, Pyridine and its Derivatives, Interscience Publishers, New York, 1961, Part 2, p. 93".
The oxidation with hydrogen peroxide is described, for example, in "E. Ochiai, J. Org. Chem. 18, 534 (1953)".
The process conditions can be taken in detail from German Patent Application P 38 26 471.4, 38 28 140.6, 39 24 093.2, 40 01 002.3 and DE-A-3,703,959, 3,703,962 and 3,703,963.
The preparation of the compounds of the formula 1 is described by N. Finch et al., J. Med. Chem. (1978), Vol. 21, page 1269 and Schneider and Harris, J. Org. Chem. (1984), Vol. 49, page 3683.
The reaction sequence according to Scheme 1 described above for the preparation of compounds of the formulae Ia and Ib having a sulfonamide group in the 5-position can also be used for the preparation of those compounds which have this sulfonamide group in the 4-position. The reaction is then started with compounds of the formula 1': ##STR4##
Compounds of the formula I in which X is a bond, Y is SO.sub.2, R.sup.4 is hydrogen and R.sup.5 is a hydroxyalkyl radical, an alkoxyalkyl radical or a derivative thereof, were prepared from the correspondingly substituted sulfonic acid derivatives of the formula 2, and methyl 4-(or 5)-aminopyridine-2'-carboxylates of the formula 1 and subsequent aminolysis of the compounds of the formula 3 (Scheme 1) with the appropriate amines.
Compounds of the formula I in which
X is --CO-- and
Y is SO.sub.2,
were prepared by
i) reacting the pyridine-2-carboxylic acid derivatives or the corresponding esters of the formula 11 with the amines of the formula 5, or
ii) reacting the pyridine-5-carboxylic acid derivatives of the formula 12 with the sulfonamide derivatives of the formula 9, or
iii) reacting the pyridine-5-carboxamide derivatives of the formula 13 with the sulfonic acid derivatives of the formula 2, cf. Scheme 2,
where the compounds of the formulae 12 and 13 were for their part prepared from the compounds of the formula 7 by the known methods.
Scheme 2 illustrates the preparation of compounds of the formula Ia or Ib, in which X is --CO-- and Y is SO.sub.2 : ##STR5##
According to CA: Vol 68, 1968, 68840 h, the pyridine-2-carboxylic acid ester 5-carboxylates of the formula 8 can be prepared from the substituted pyridine-2,5-dicarboxylic acids of the formula 7 under esterification conditions. Suitable conditions are, for example, esterification with methanol in the presence of sulfuric acid, the reaction time being selected such that complete esterification to give the diester product only takes place to an insignificant extent, or the diester products can be removed as by-products.
The compounds of the formula 11 are prepared from the compounds of the formula 8 and the sulfonamide derivatives of the formula 9 (Y=SO.sub.2), it possibly being expedient to activate both reactants with auxiliary reagents (Houben-Weyl: Methoden der Organischen Chemie (Methods of Organic Chemistry), Volume IX, Chapter 19, pages 636-637).
By way of reagents for carboxylic acid activation, the substances known to the person skilled in the art, such as thionyl chloride, oxalyl chloride, pivaloyl chloride or chloroformic acid ester derivatives, can be used. It is not always necessary to isolate these activated derivatives of the compounds of the formula 8. It is usually expedient to react them after preparation in situ or as a crude product with the sulfonamide derivatives of the formula 9.
Expediently, the compounds of the formula 9 are first caused to react with an inorganic or organic base, such as, for example, the hydroxide, carbonate, alkoxide, hydride or amide of sodium or potassium, ammonia, triethylamine, tributylamine or pyridine at -20.degree. to +150.degree. C., preferably at 0.degree.-80.degree. C. and this reaction mixture is reacted with a compound of the formula 8 or its activated form. The reaction is carried out in an inert solvent, such as, for example, methylene chloride, methanol, ethanol, acetone, ethyl acetate, toluene, tetrahydrofuran, acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, nitromethane, dimethyl sulfoxide or mixtures of these solvents. Alternatively, the esters of the formula 11 can be prepared with the aid of the customary condensation reagents (such as, for example, N,N'-dicyclohexylcarbodiimide/4-N,N-dimethylaminopyridine).
The reaction of the pyridine-2-carboxylic acid esters 11 with amines HNR.sup.4 R.sup.5 leads to the compounds of the formula Ia' according to the invention.
Alternatively, for the preparation of the compounds of the formula Ia', the compounds 11 (R=lower alkyl) can be hydrolyzed to give the pyridine-2-carboxylic acid derivatives 11 (R=H) and these can then be coupled with the amines HNR.sup.4 R.sup.5 by the customary methods of peptide chemistry to give the compounds of the formula Ia' according to the invention.
The further reaction of the pyridine-N-oxides of the formula Ib' is already illustrated in Scheme 1 (reaction of compound Ia to give compound Ib).
The reaction sequence according to Scheme 2 described above for the preparation of compounds of the formulae Ia' or Ib' having a carbonylsulfonamide group in the 5-position can also be used for the preparation of those compounds which have a carbonylsulfonamide group in the 4-position. The reaction is then started with compounds of the formula 7': ##STR6##
Compounds of the formula I, in which X is CO, Y is SO.sub.2, R.sup.4 is hydrogen and R.sup.5 is a hydroxyalkyl radical, an alkoxyalkyl radical or a derivative thereof, were prepared from the correspondingly substituted sulfonamides of the formula 9 and 2-methoxycarbonylpyridine-4-(or 5)-carboxylic acid and subsequent aminolysis of the compounds of the formula 11 (R=lower alkyl; Scheme 2) with the corresponding amines.
For the preparation of the compounds of the formula I in which NR.sup.4 R.sup.5 is a glycyl residue, the compounds of the formulae 3 and 11 (R=lower alkyl) were hydrolyzed to give the pyridine-2-carboxylic acid derivatives of the formulae 4 and 11 (R=H) and these were condensed with the corresponding glycine derivatives.
The free glycyl amides, in which NR.sup.4 R.sup.5 is NHCH.sub.2 CO.sub.2 H, were obtained by hydrolysis of the (glycyl ester) amides or by catalytic hydrogenation of the glycyl benzyl esters.
For the preparation of compounds of the formula I (Ia, Ib, Ia', Ib') according to the Schemes 1 and 2, compounds are employed in which R.sup.6 is hydrogen. Salt formation, after which R.sup.6 is a physiologically utilizable cation, is preferably carried out subsequently. Suitable salt-forming agents are preferably N-alkylamines, (hydroxyalkyl)amines and (alkoxyalkyl)amines, such as, for example, 2-ethanolamine, 3-propanolamine, 2-methoxyethylamine, 2-ethoxyethylamine and .alpha.,.alpha.,.alpha.-tris(hydroxymethyl)methylamine (=tris buffer, tromethamine) or alternatively basic amino acids, such as, for example, histidine, arginine and lysine.
The compounds of the formula I according to the invention have useful pharmacological properties and in particular exhibit antifibrotic activity.
The antifibrotic action can be determined in the carbon tetrachloride-induced liver fibrosis model. For this purpose, rats are treated twice weekly with CCl.sub.4 (1 ml/kg)--dissolved in olive oil. The test substance is administered daily, if necessary even twice daily, orally or intraperitoneally--dissolved in a suitable, tolerable solvent. The extent of liver fibrosis is determined histologically and the content of collagen in the liver is analyzed by hydroxyproline determination--as described by Kivirikko et al. (Anal. Biochem. 19, 249 et seq. (1967)). The fibrogenesis activity can be determined by radioimmunological determination of collagen fragments and procollagen peptides in the serum. The compounds according to the invention are active in this model at a concentration of 1-100 mg/kg.
The fibrogenesis activity can be determined by radioimmunological determination of the N-terminal propeptide of collagen type III or of the N- or C-terminal cross-linking domain of collagen type IV (7s collagen or type IV collagen NC.sub.1) in the serum.
For this purpose, the hydroxyproline, procollagen III peptide, 7s collagen and type IV collagen NC concentrations were measured in the liver of
a) untreated rats (control)
b) rats to whom carbon tetrachloride was administered (CCl.sub.4 control)
c) rats to whom first CCl.sub.4 and then a compound according to the invention were administered
(this test method is described by Rouiller, C., experimental toxic injury of the liver; in The Liver, C. Rouiller, Vol. 2, 5. 335-476, New York, Academic Press, 1964).
The compounds of the formula I can be used as medicaments in the form of pharmaceutical preparations which contain them, if appropriate together with tolerable pharmaceutical excipients. The compounds can be used as medicines, for example in the form of pharmaceutical preparations which contain these compounds in a mixture with a pharmaceutical, organic or inorganic excipient suitable for enteral, percutaneous or parenteral administration, such as, for example, water, gum arabic, gelatin, lactose, starch, magnesium stearate, talc, vegetable oils, polyalkylene glycols, petroleum jelly etc.
They can be administered orally for this purpose in doses of 0.1-25 mg/kg/day, preferably 1-5 mg/kg/day or parenterally in doses of 0.01-5 mg/kg/day, preferably 0.01-2.5 mg/kg/day, in particular 0.5-1.0 mg/kg/day. The dosage can also be increased in severe cases. In many cases, however, lower doses are also adequate. These data relate to an adult having a weight of about 75 kg.
The invention furthermore comprises the use of the compounds according to the invention in the production of pharmaceuticals which are employed for the treatment and prophylaxis of the abovementioned metabolic disorders.
The invention furthermore relates to pharmaceuticals which contain one or more compounds of the formula I according to the invention and/or their physiologically tolerable salts.

The 2-methoxycarbonylpyridine-5-carbonyl chloride prepared from 4.0 g (22 mmol) of 2-methoxycarbonylpyridine-5-carboxylic acid, as described in Example 1 c), was added in 50 ml of anhydrous 1,4-dioxane at 40.degree. C. to the reaction mixture of 7.4 g (20 mmol) of 2-(((2-chloro-5-methoxybenzoyl)amino)ethyl)benzenesulfonamide (prepared from 4-(2-aminoethyl)benzenesulfonamide and 2-chloro-5-methoxybenzoic acid) and 2.3 g (20 mmol) of potassium tert-butoxide in 150 ml of anhydrous 1,4-dioxane (had been stirred at 50.degree. C. for 15 min to form the sulfonamide sodium salt).
The reaction mixture was stirred at 60.degree. C. for 90 min, then under reflux for 2 h, the solvent was distilled off in vacuo, the residue was treated with water and the mixture was brought to pH 1-2 using aqueous HCl and extracted with dichloromethane. The residue was treated with hot ethyl acetate, filtered off with suction and washed with ethyl acetate. The crude product thus obtained (2.8 g) was treated with 100 ml of cold water, then with 100 ml of hot water, and the colorless crystalline product was filtered off with suction. 2.6 g were obtained, M.p. 187.degree.-190.degree. C.
b) 0.85 g (1.6 mmol) of the above methyl ester was stirred at 80.degree. to 90.degree. C. for 1 h in 150 ml of 2-aminoethanol. After cooling, excess reagent was distilled off in vacuo, the residue was dissolved in 20-30 ml of water, the solution was brought to pH 1 with conc. aqueous HCl, and the crystalline product was filtered off with suction, washed with water, treated with hot ethyl acetate and again filtered off with suction. 0.65 g of the title compound was obtained, M.p. 135.degree.-137.degree. C.
