Naphthyridine derivatives {NOVEL NAPHTHYRIDINE DERIVATIVES} Cerebrovascular disorders such as stroke, myocardial infarction, etc., which are the leading causes of death in developed countries, all develop atherosclerosis as a basic disease. The results of epidemiologic studies indicate that hypercholesterolemia is one of the risk factors for atherosclerosis, and antihyperlipidemic drugs that lower blood cholesterol are mainly used for the prevention and treatment of the same disease, but the effect is not critical. In recent years, it has been observed that cells derived from macropurge in the pathogenesis of atherosclerosis are localized with cholesterol esters within the cells and foamed, and are deeply involved in the development of the lesions (Arteriosclerosis 10, 164). To 177, 1990). In addition, it has been reported that cholesterol esters accumulate in the blood vessel wall due to an increase in the ACAT activity of the vessel wall of the atherosclerotic lesion (Biochem. Biophys. Acta 617, 458 to 471, 1980). Therefore, the inhibitor of ACAT, which is an esterification enzyme of cholesterol, can suppress the formation of the arteriosclerosis lesions by inhibiting the foaming of the macro purge and inhibiting the accumulation of cholesterol esters in the lesion site. Cholesterol in plants, on the other hand, is absorbed in intestinal epithelial cells in a free form, then esterified by ACAT and released into the blood in chiromicron form. Thus, inhibitors of ACAT inhibit the intestinal absorption of cholesterol in plants and also inhibit the reabsorption of cholesterol released into the intestine, thereby lowering blood cholesterol (J. Lipid. Research, 34, 279 to 294, 1993).
