Substituted heterocyclic carboxamide esters, their preparation and their use as pharmaceuticals

Description

The invention relates to substituted heterocyclic carboxamide esters, to their preparation and to their use for inhibiting collagen biosynthesis, and to their use as pharmaceuticals for treating fibrotic diseases.
Compounds which inhibit the enzymes proline hydroxylase and lysine hydroxylase bring about a very selective inhibition of collagen biosynthesis by their influence on the collagen-specific hydroxylation reactions. In the course of these reactions, protein-bound proline or lysine is hydroxylated by the enzymes proline hydroxylase. or lysine hydroxylase, respectively. If this reaction is prevented by inhibitors, there then arises a non-functional, subhydroxylated collagen molecule which can only be secreted by the cells into the extracellular space in small quantities. Furthermore, the subhydroxylated collagen cannot be incorporated into the collagen matrix and is very readily degraded proteolytically. These effects result in a diminution of the overall quantity of collagen which is deposited extracellularly.
Inhibitors of prolyl hydroxylase are therefore suitable substances for use in the therapy of diseases in which the deposition of collagens makes a substantial contribution to the clinical picture. These diseases include, inter alia, fibroses of the lung, liver and skin (scleroderma and cicatrizations following burns, injuries and surgical intervention) and also atherosclerosis.
It is known that the enzyme proline hydroxylase is efficiently inhibited by pyridine-2,4-dicarboxylic acid and pyridine-2,5-dicarboxylic acid (K. Majamaa et al.,
Eur. J. Biochem. 138 (1984) 230-245). However, these compounds are only active as inhibitors in cell culture at very high concentrations (Tschank, G. et al., Biochem. J. 238 (1987) 625-633).
Prodrugs of pyridine-2,4(5)-dicarboxylates are also known. These are described in the relatively old German Applications P 42 33 124.2, P 42 38 506.7 and P 42 09 424.0.
N-Oxalylglycines which are inhibitors of prolyl-4-hydroxylase are disclosed in J. Med. Chem. 1992, 35, 2652-2658 (Cunliffe et al.) and EP-A-0 457 163.
Hydroxyisoquinolinecarboxylic acid glycyl amides and hydroxycinnolinecarboxylic acid glycyl amides are disclosed in Biochem. Soc. Trans. 1991, 19, 812-815 (Franklin et al.). 3-Benzyloxypyridine-2-carboxylic acid (L-threonyl methyl ester) amide, 3-benzyloxypyridine-2-carboxylic acid (L-threonyl(Fmoc-Phg) tert-butyl ester) amide, 3-benzyloxypyridine-2-carboxylic acid (L-threonyl tert-butyl ester) amide and 3-benzyloxypyridine-2-carboxylic acid (D-allothreonyl methyl ester) amide are disclosed in Liebigs Ann. Chem., 1986, 1-20, Kessler et al.
In addition, 3-benzyloxypyridine-2-carboxylic acid (glycyl ethyl ester) amide is described in J. Org. Chem. 31, 636-638 (1966).
It has now been found, surprisingly, that heterocyclic carboxamides of the formula I having an ether substituent, a thioether substituent or an amino substituent in the ortho position to the amide function have a strong inhibitory action on collagen biosynthesis in vivo.
The compounds are ester prodrugs of the corresponding carboxylic acids of the formula I in which B is a carboxyl group.
The compounds of the formula I are cleaved in the living organism (in vivo) and in cell cultures (in vitro) to form compounds of the formula I in which B is a carboxyl group or its salts.
Once the compounds of the formula I have been administered, they bring about the inhibition, which is to be observed in vivo and in vitro, of collagen biosynthesis by forming compounds of the formula I in which B is a carboxyl group or its salts. These compounds inhibit prolyl-4-hydroxylase and therefore lead to an inhibition of collagen biosynthesis.

In general, aryl is understood to mean carbocyclic and heterocyclic aromatic ring systems. In particular, it is understood to include phenyl-substituted, biphenyl-substituted, naphthyl-substituted or unsubstituted 5- and 6-membered heteroaromatic rings having 1, 2 or 3 nitrogen and/or oxygen and/or sulfur atoms, such as derivatives of pyridyl, pyridazyl, pyrimidyl, pyrazyl, imidazolyl, triazolyl, thienyl, oxazolyl and thiazolyl, and their benzo-fused derivatives.
The invention also embraces salts of the compounds of the formula I.
The formation of salts with basic reagents can take place once, twice or three times on the acidic groups of the compounds of the formula I (i.e. radicals B, R.sup.1, R.sup.2, R.sup.3 and R.sup.4), in particular on the radical R.sup.2.
Examples of reagents being used are alcoholates, hydroxides, carbonates, hydrogen carbonates, hydrogen phosphates, organometallic compounds of the alkali and alkaline earth elements, the elements of the third and fourth main groups of the periodic system, and the elements of the transition metals, amines, optionally substituted 1 to 3 times by (C.sub.1 -C.sub.8)-hydroxyalkyl, (C.sub.1 -C.sub.4)-alkoxy-(C.sub.1 -C.sub.8)-alkyl, phenyl, benzyl or (C.sub.1 -C.sub.8)-alkyl, which can be substituted 1 to 3 times by hydroxyl or (C.sub.1 -C.sub.4)-alkoxy, for example tromethane (Tris buffer), 2-aminoethanol, 3-aminopropanol, hydroxylamine, dimethylhydroxylamine, 2-methoxyethylamine, 3-ethoxypropylamine, and basic amino acids and amino derivatives, such as amino acid esters, histidine, arginine and lysine, and their derivatives, and also pharmaceuticals which contain a basic group, such as, for example, .RTM.Amiloride, .RTM.Verapamil and beta blockers.
The invention also relates to the compounds according to Formula I, plus 3-benzyloxypyridine-2-carboxylic acid (L-threonyl methyl ester) amide, 3-benzyloxypyridine-2-carboxylic acid (L-threonyl(Fmoc-Phg) tert-butyl ester) amide, 3-benzyloxypyridine-2-carboxylic acid (L-threonyl tert-butyl ester) amide and 3-benzyloxypyridine-2-carboxylic acid (D-allothreonyl methyl ester) amide for use as pharmaceuticals.

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 fibrosuppressive agents.
The invention also relates to a process for preparing compounds of the formula I.
The compounds of the formula I, in which A is a substituted alkylene moiety, B is CO.sub.2 G, Y is CR.sup.3 and m is 0 or 1, are prepared by
i1.) reacting pyridine-2-carboxylic acids of the formula II (R.sup.23 is H) with the amino esters of the formula III to form the amide esters of the formula I, or
i2.) reacting pyridine-2-carboxylic esters of the formula II (R.sup.23 is (C.sub.1 -C.sub.16)-alkyl) to form the compounds of the formula I under the conditions of aminolysis; or
ii) esterifying the compounds of the formula IV with the alcohol GOH; or
iii) alkylating the compounds of the formula V with R.sup.4 X, and, where appropriate,
iv) converting the compounds of the formula I, provided Q is O or NR', into their pyridine N-oxides (Formula I'). ##STR9## R.sup.23 is H or (C.sub.1 -C.sub.16)-alkyl, X is a leaving group, in particular: halogen, OSO.sub.2 Me or OSO.sub.2 phenyl, inter alia.
The methods of carboxyl activation and the condensation reactions known from peptide chemistry are suitable processes for the amide formation (reaction i1).
The substances which are known to the person skilled in the art, such as thionyl chloride, oxalyl chloride, pivaloyl chloride, chloroformate derivatives, or N,N'-carbonyldiimidazole, can be used as reagents for the carboxylic acid activation. The activated derivatives of the compounds of the formula II are prepared in situ and then reacted with the amide derivatives of the formula III.
An example of a suitable condensing agent is the combination of N,N'-dicyclohexylcarbodiimide/N-hydroxy-1H-benzotriazole and N-ethylmorpholine.
Suitable solvents are dichloromethane, tetrachloromethane, butyl acetate, ethyl acetate, toluene, tetrahydrofuran, dimethoxyethane, 1,4-dioxane, acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, dimethylsulfoxide, nitromethane and/or pyridine.
The compounds of the formula I, in which R.sup.1 and R.sup.3 are hydrogen and R.sup.2 is a carboxyl substituent, a carbamoyl substituent or an ester substituent, were prepared as outlined in schemes 1, 2 and 3.
Scheme 2 illustrates the preparation of the compounds of the formula II in which R.sup.2 is a carboxylic acid substituent, or its derivative, and R.sup.1 and R.sup.3 are hydrogen.
The 3-substituted 5-carboxypyridine-2-carboxylic esters of the formula XI and their isomers of the formula XII are prepared from the pyridine-2,5-dicarboxylic diesters of the formula VII.
The oxidation of the pyridine-2,4-dicarboxylates of the formula VII is described in J. Chem. Soc. Perkin Trans. 2, 1978, 34-38 and in J. Org. Chem. 25 (1960) 565 to 568 (M. L. Peterson).
The halogenation (chlorination) of the pyridine N-oxides of the formula VIII with thionyl chloride and the reaction of the 3-chloropyridine-2,5-dicarboxylic diester (Formula IX) with alcoholates (Q is O or S) can be carried out in analogy with the process described in the patent specification CH 658 651 (LONZA), where M is a singly charged or doubly charged metal ion, preferably from the first or second main group of the periodic system.
In analogy with the known literature (CA: vol. 68, 1968, 68 840 h), the monoesters of the formula XII are prepared, under hydrolysis conditions, from the substituted pyridine-2,5-dicarboxylic diesters of the formula Xb.
Selective hydrolysis using Cu(II) salts, J. Delarge in Pharmaceutica Acta Helvetiae 44, 637-643, 1969, represents another process for preparing the compounds of the formula XII from the diesters of the formula Xb.
The compounds of the formula XII thus obtained are reacted with the amino esters of the formula III to form the compounds of the formula IV (Scheme 2).
The pyridine-2-carboxylic acid ester-5-carboxylates of the formula XI can be prepared, under esterification conditions, from substituted pyridine-2,5-dicarboxylic acids of the formula Xa (see CA: vol. 68, 1968, 68840 h). Suitable conditions are, for example, esterification with methanol in the presence of sulfuric acid, it being necessary to choose the reaction time so that complete esterification to form the diester product only takes place to a secondary extent, or so that the diester products can be separated off as by-products.
The compounds of the formula XI are converted with amines or alcohols into the 5-carboxylic acid derivatives of the formula XIV (Scheme 3).
These are then hydrolysed to form the compounds of the formula II (R.sup.23 is H), which compounds are subsequently reacted in analogy with Scheme 1. ##STR10##
The 2-hydroxymethylpyridines of the formula VIa, which are disclosed in EP-A-0 304 732, EP-A-0 321 385 and EP-A-0 208 452, can be used as intermediates for preparing derivatives (R.sup.1) which are substituted in the 4 position. ##STR11##
The 3--O-benzyl derivatives of the formula VIb were also obtained in an analogous manner, as described in these documents.
The compounds of the formulae VIa and VIb were reacted with an oxidizing agent, preferably with KMnO.sub.4 in aqueous alkaline medium, to form the pyridine-2-carboxylic acid derivatives of the formula II.
The preparation of substituted pyridine-2-carboxylic acids is, for example, disclosed in DE-A-353 046, and for 3-(3-chlorophenoxy)pyridine-2-carboxylic acid and 3-(3-methylphenoxy)pyridine-2-carboxylic acid in J.

The novel compounds of the formula I possess valuable pharmacological properties and exhibit, in particular, antifibrotic activity.
The antifibrotic effect can be determined using the model of carbon tetrachloride-induced hepatic fibrosis. For this, rats are treated twice a week with CCl.sub.4 (1 ml/kg)--dissolved in olive oil. The substance under test is administered daily, where appropriate even twice a day, per os, or intraperitoneally--dissolved in a suitable tolerated solvent. The extent of the hepatic fibrosis is determined by histology, and the proportion of collagen in the liver is analyzed by means of determining hydroxyproline--as described in Kivirikko et al. (Anal. Biochem. 19, 249 f. 1967)). The fibrogenic activity can be measured by the radioimmunological determination of collagen fragments and procollagen peptides in the serum. In this model, the novel compounds are active at a concentration of from 1 to 100 mg/kg.
The fibrogenic activity can be measured by radioimmunological determination of the N-terminal propeptide of collagen type III or of the N-terminal or C-terminal crosslinking domain of collagen type IV (7s collagen or type IV collagen NC.sub.1) in the serum.
For this purpose, measurements were made of the concentrations of hydroxyproline, procollagen III peptide, 7s collagen and type IV collagen NC in the liver of
a) untreated rats (control)
b) rats which were administered carbon tetrachloride (CCl.sub.4 control)
c) rats which were first administered CCl.sub.4 and then a novel compound (this test method is described by Rouiller, C., Experimental toxic injury of the liver; in The Liver, C. Rouiller, vol. 2, 5. 335 to 476, New York, Academic Press, 1964).
The novel compounds can also be demonstrated to be active in the following systems.
Inhibition of hepatic prolyl-4-hydroxylase in vivo:
This model is used to demonstrate the acute inhibition of prolyl-4-hydroxylase in vivo. For this, rats of both sexes (healthy or with induced hepatic fibrosis) are administered (intraperitoneally, intravenously or per os) the substance under test or the corresponding vehicle and, after this, are given .sup.14 C-L-proline (250 .mu.Ci/kg of body weight), which is administered intraperitoneally. There then follows a second intraperitoneal administration of .sup.14 C-L-proline (250 .mu.Ci/kg of body weight). Finally, the animals are exsanguinated under pentobarbital anesthesia and the livers removed. The hepatic collagen was purified by digestion with pepsin and fractional ammonium sulfate precipitation in conformity with published protocols (Ref. 1 and 2). The purified liver collagen was hydrolyzed and the content of .sup.14 C-hydroxyproline and .sup.14 C-proline was determined by means of amino acid analysis using ion exchange chromatography. Inhibition of prolyl-4-hydroxylase is shown by a decrease in the quotient .sup.14 C-hydroxyproline/[.sup.14 C-hydroxyproline+.sup.14 C-proline]. 2,2'-Dipyridyl is used as the reference substance. (1: Chojkier, M. 1986, Hepatocyte collagen production in vivo in normal rats, J. Clin. Invest. 78: 333-339 and 2: Ogata I., et al. 1991, Minor contribution of hepatocytes to collagen production in normal and early fibrotic livers, Hepatology 14: 361-367).
Inhibition of prolyl-4-hydroxylase in cell cultures: The following cell types are used for testing inhibitors of prolyl-4-hydroxylase in cell cultures:
Normal human skin fibroblasts, (NHDF), rat liver epithelial cells (ref. 1) and primary fat storing cells from rat liver (ref. 2). For this, the cells are cultivated in the presence of inhibitors. At the same time, the collagen which is newly synthesized during this period is metabolically labelled with 4-.sup.3 H-L-proline and .sup.14 C-proline. The influence of the test substances on the degree of hydroxylation of the collagen is then determined in accordance with the method of Chojkier et al (ref. 3). 2,2'-Dipyridyl is employed as the reference substance. (1.: Schrode, W., Mecke, D., Gebhard, R. 1990, Induction of glutamine synthetase in periportal hepatocytes by co-cultivation with a liver epithelial cell line, Eur. J. Cell. Biol. 53: 35-41; 2. Blomhoff, R., Berg T. 1990, Isolation and cultivation of rat liver stellate cells, Methods Enzymol. 190: 59-71; and 3.: Chojkier, M. Peterkofsky, B. Bateman, J. 1980, A new method for determining the extent of proline hydroxylation by measuring changes in the ration of [4-.sup.3 H]:[.sup.14 C]proline in collagenase digests, Anal. Biochem. 108: 385-393).
The compounds of the formula I may be used as medicaments in the form of pharmaceutical preparations, which contain the compounds, where appropriate together with tolerated pharmaceutical excipients. The compounds can be used as medicines, for example in the form of pharmaceutical preparations which contain these compounds in a mixture together with a pharmaceutical, organic or inorganic excipient which is suitable for enteral, percutaneous or parenteral administration, such as, for example, water, gum arabic, gelatin, lactose, starch, magnesium stearate, talc, vegetable oils, polyalkylene glycols, vaseline, etc.
For this purpose, they can be administered orally in doses of from 0.1 to 23 mg/kg/day, preferably of from 1 to 5 mg/kg/day, or parenterally in doses of from 0.01 to 5 mg/kg/day, preferably of from 0.01 to 2.5 mg/kg/day, in particular of from 0.5 to 1.0 mg/kg/day. The dosage can also be increased in severe cases. In many cases, however, smaller doses are also Sufficient. These data refer to an adult of about 75 kg in weight.
The novel compounds of the formula I are designated substituted heterocyclic carboxylic acid (amino acid ester) amides, preferably pyridine-2-carboxylic acid (glycyl ester) amides, in the examples described below. This mode of designation is understood to mean, for example, substituted pyridine-2-carboxylic acid N-((alkoxycarbonyl)methyl)amides.
Another option is to classify them as substituted N-(pyridyl-2-carbonyl)glycines.
