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 nonfunctional, 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. <br><br> 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 aad surgical intervention) and also atherosclerosis. <br><br> 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.. <br><br> # <br><br> - 2 <br><br> 264 82 1 <br><br> Eur. J. Biochem. 138 (1984) 239-245) . However, these compounds are only active as inhibitors in cell culture at very high concentrations (Tschank, G. et al., Biochem. J. 238 (1987) 625 to 633). <br><br> 5 Prodrugs o£ pyridine-2,4(5)-dicarboxylates are also known.

The inhibition of this enzyme was determined as described by Kaule and Qdnzler in Annal. 10 Biochem. 184, 219 to 297 (1990) . <br><br> The novel compounds of the formula I possess valuable pharmacological properties and exhibit, in particular, antifibrotic activity. <br><br> The antifibrotic effect can, for example, be determined 15 using the model of carbon tetrachloride-induced hepatic fibrosis. For this, rats are treated twice a week with CC14 (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 20 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. <br><br> (Anal. Biochem. 19, 249 f. (1967)). The fibrogenic ac-25 tivity 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. <br><br> The fibrogenic activity can be measured by radioimmuno-30 logical 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 NCX) in the serum. <br><br> For this purpose, measurements were made of the <br><br> 47 - <br><br> 264 82 1 <br><br> concentrations of hydroxyproline, procollagen III peptide, 7s collagen and type IV collagen NC in the liver of a) untreated rats (control) <br><br> 5 b) rats which were administered carbon tetrachloride (CC14 control) <br><br> c) rats which were first administered CC14 and then a novel compound (this test method is described by Rouiller, C., Experi-10 mental toxic injury of the liver; in The Liver, C. Rouiller, vol. 2, 5. 335 to 476, New York, Academic Press, 1964) . <br><br> The novel compounds can also be demonstrated to be active in the following systems. <br><br> 15 Inhibition of hepatic prolyl-4-hydroxylase in vivo: <br><br> This model is used to demonstrate the acute inhibition of prolyl-4-hydroxylase in vivo. For thl?, rats of both sexes (healthy or with induced hepatic fibrosis) are administered (intraperitoneally, intravenously or per os) 20 the substance under test or the corresponding vehicle and, after this, are given "C-L-proline (250 pCi/kg of bodyweight), which is administered intraperitoneally. There then follows a second intraperitoneal administration of 14C-L-proline (250 pCi/kg of bodyweight) . 25 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 30 liver collagen was hydrolyzed and the content of 14C-hydroxyproline and 14C-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 l4C-hydroxyproline/ [14C-hydroxy-35 proline+14C-proline] . 2,2' -Dipyridyl is used as the reference substance.

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). <br><br> Inhibition of prolyl-4-hydroxylase in cell cultures: <br><br> The following cell types are used for testing inhibitors of prolyl-4-hydroxylase in cell cultures: <br><br> 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 iis metabolically labelled with 4-sH-L-proline and X4C-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.
