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 Ar
1
and Ar
2
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 alkoxy carbonyl 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.
提供了一种血小板凝血抑制剂,它既不抑制COX-1也不抑制COX-2。该抑制剂是由通式(I)表示的化合物:其中Ar1和Ar2独立地表示一个5-或6-成员的芳香杂环基团,可选地取代1至3个取代基,或一个苯基,可选地取代1至3个取代基;R1表示较低的酰基,羧基,较低的烷氧羰基,较低的烷氧基,较低的烷基,可选地取代1或2个取代基的氨基甲酰基,可选地取代1或2个取代基的草酰基,可选地取代1或2个取代基的氧代草酰基,可选地取代1或2个取代基的氨基,可选地取代1或2个取代基的4-至7-成员脂环杂环基团,可选地取代1或2个取代基的苯基,或可选地取代1至3个取代基的5-或6-成员芳香杂环基团;R2表示氢原子,卤素基或类似物。
