The metabolites of 6-[4-(1-cyclohexyl-1H-5-tetrazolyl) butoxy]-2-oxo-1, 2, 3, 4-tetrahydroquinoline (OPC-13013) (1), which has a potent inhibitory activity toward blood platelet aggregation and a cerebral vasodilating activity, were synthesized to confirm their structures and to examine their inhibitory activity. The structures of four major metabolites (2a-c and 3) and a specific metabolite (4) found only in man were identified unequivocally by means of comparisons with the synthetic compounds. The inhibitory activity of 3, 4-dehydro-OPC-13013 (3) was about three times higher than that of 1, whereas two metabolites (2a and 2c) had activity almost equal to that of 1.
6-[4-(1-环己基-1H-5-四唑基)丁氧基]-2-氧代-1,2,3,4-四氢喹啉(OPC-13013)(1)的代谢产物,该化合物具有强效的血小板聚集抑制活性和脑部血管舒张活性,被合成以确认其结构并检测其抑制活性。通过与合成化合物进行比较,明确鉴定出四种主要代谢产物(2a-c和3)和一个仅在人体中发现的具体代谢产物(4)的结构。3,4-去氢-OPC-13013(3)的抑制活性约为1的三倍,而两种代谢产物(2a和2c)的活性与1几乎相等。
