Description
DERIVATIVE OF PIRIDINE AND PHARMACEUTICAL COMPOSITION CONTAINING THE SAME
TECHNICAL FIELD
The present invention relates to a novel pyridine derivative or to a salt thereof, which inhibits the synthesis of collagen, and to a pharmaceutical composition containing said compound, which is useful for the prophylaxis or treatment of fibrosis. 10 PREVIOUS TECHNIQUE * r
In the present, it is said that there are 130 types of diseases or more called fibrosis, among which strange diseases are included.
The typical fibrosis disease includes, for example, pulmonary fibrosis, hepatic fibrosis, glomerulosclerosis, etc. Pulmonary fibrosis generally refers to a syndrome in which lung function has been lost due to a reconstituted lesion in the alveolar region, that is, an alveolar structure is broken by the reaction
inflammatory cell that causes the growth of fibroblasts and an excessive increase of the extracellular matrix composed mainly of collagen, which results in pulmonary sclerosis.
On the other hand, hepatic fibrosis refers to the condition of the diseases in which the necrosis of the hepatocytes is caused by various liver diseases such as chronic viral hepatitis, alcoholic liver disease, etc. and, therefore, the extracellular matrix increases to recruit for the site, which generates hepatic fibrogenesis. The terminal state of this disease condition leads to liver cirrhosis where all the liver tissue atrophies and sclerose. Conventional drugs that inhibit hepatic fibrogenesis described above include, for example, the penicillamine known 10 as a remedy for Wiikinson's disease that occurs due to the accumulation of copper in the liver as a result of a metabolism.
»Abnormal copper, Lufironil that has been studied as an inhibitor of proline hydroxylase, etc. However, these drugs are not enough as a drug
to prevent hepatic fibrogenesis in view of side effects and validity. At present, a remedy (or therapy) that is effective for fibrosis represented by hepatic fibrogenesis has not been established, and the production of fibrogenesis has been specifically inhibited. As described in the foregoing, it has been known that it is generated
an excessive increase of the extracellular matrix composed mainly of collagen in the production of fibrogenesis in lung tissues and hepatocytes. It has also been known that an increase in the extracellular matrix in hepatocytes is generated mainly in a Disse space of the sinusoidal wall and that Ito cells such as the mesenchymal cells of the liver constitute an important source of production. Accordingly, it is important that an excessive increase in the extracellular matrix (i.e., collagen) is inhibited in order to inhibit fibrogenesis of the liver, lung, etc. Thus, an object of the present invention is to provide a novel compound that has a greater inhibitory effect on the production of collagen, and a pharmaceutical composition with content thereof, useful for the prophylaxis or treatment of fibrosis.

The tablets obtained are coated with a film coating agent containing TC-5, polyethylene glycol-6000, castor oil and ethanol to produce film-coated tablets of the aforementioned composition.
Test Example The pyridine derivatives (test compounds) obtained in examples 1 -2, 9-10, 21, 25, 29, 33-37, 39, 42, 44 and 46 were subjected to the following synthesis test of Collagen [Test for the inhibition of collagen synthesis] (Preparation of plasma-derived serum (PDS)) The plasma obtained from the centrifugation of rabbit blood was again subjected to centrifugation to remove the platelets, and the dialysis of the supernatant was carried out against a Phosphate buffered saline solution (PBS) with 0.01% (w / v) calcium chloride and 0.01% (w / v) magnesium chloride. Then, another centrifugation was performed to remove the residue and the resulting supernatant was immobilized for 30 minutes at 56 ° C. The immobilized supernatant was sterilized by means of a filter (0.22 μM) to prepare the serum derived from the plasma (PDS).
(Method for determination) Cultured human "Ito" cells (LOO) were inoculated into a modified Eagle medium of DULBECCO (DMEM) with 10% fetal bovine serum and cultured in an incubator with 5% carbon dioxide (C02) during 24 hours at 37 ° C, and subsequently washed with PBS and cultured in Eagle's minimal essential medium (MEM) containing 2% PDS for another 3 days. The cultured cells were washed with PBS and cultured together with the test compounds in MEM with 10 PM hTGF (transforming growth factor) ß-? (with 2% of PDS on the basis of total MEM) for 16 hours. Subsequently, culture L190 was washed with PBS and marked Rl (radioisotopes) in MEM with 3H proline as radioactivated compound and 0.25 mM ascorbic acid for 24 hours. This cultivated supernatant was precipitated with trichloroacetic acid (TCA), and then the radioactivity was measured in an acid soluble fraction and the resulting measured value was considered as the activity of collagen synthesis. When comparing the radioactivity in the cultured supernatant containing the test compound with the radioactivity in the cultured supernatant that did not contain the test compound (control), the inhibition activity of collagen synthesis (T / C) was calculated by the following equation: T / C = (the radioactivity in the supernatant grown with test compound) / (the radioactivity in the supernatant cultured control). IC50 was determined as the concentration (μM) at which the synthesis of collagen can be inhibited by 50% (concentration of the test compound where IC5o = T / C corresponds to 0.5). These test results are found in Table 1.
