A platelet coagulation inhibitor which inhibits neither COX-1 nor COX-2 is provided. The inhibitor is a compound represented by general formula (I):
wherein Ar1 and Ar2 independently represent a 5- or 6-membered aromatic heterocyclic group optionally substituted with 1 to 3 substituents, or a phenyl group optionally substituted with 1 to 3 substituents; R1 represents a lower acyl group, carboxyl group, a lower alkoxycarbonyl group, a lower alkoxy group, a lower alkyl group optionally substituted with 1 or 2 substituents, a carbamoyl group optionally substituted with 1 or 2 substituents, an oxamoyl group optionally substituted with 1 or 2 substituents, an amino group optionally substituted with 1 or 2 substituents, a 4- to 7-membered alicyclic heterocyclic group optionally substituted with 1 or 2 substituents, a phenyl group optionally substituted with 1 to 3 substituents, or a 5- or 6-membered aromatic heterocyclic group optionally substituted with 1 to 3 substituents; and R2 represents hydrogen atom, a halogeno group, or the like.
提供了一种既不抑制 COX-1 也不抑制 COX-2 的血小板凝固抑制剂。该抑制剂为通式 (I) 所代表的化合物:
其中 Ar1 和 Ar2 独立地代表任选被 1 至 3 个取代基取代的 5 或 6 元芳香杂环基团,或任选被 1 至 3 个取代基取代的苯基;R1 代表低级酰基、羧基、低级烷氧羰基、低级烷氧基、任选被 1 或 2 个取代基取代的低级烷基、任选被 1 或 2 个取代基取代的氨基甲酰基、任选被 1 或 2 个取代基取代的草酰基、任选被 1 或 2 个取代基取代的氨基,任选被 1 或 2 个取代基取代的 4 至 7 元脂环杂环基团,任选被 1 至 3 个取代基取代的苯基,或任选被 1 至 3 个取代基取代的 5 或 6 元芳香杂环基团;R2 代表氢原子、卤素基团或类似物。
