Compound are described of the general formula
wherein
R¹ is a hydrogen atom or a C1-4 alkyl group;
R² is a naphthyl, thienyl or β-styryl group or a group Ar(CH₂)p- where p is zero or an integer from 1 to 3 and Ar is phenyl or phenyl substituted by one or more halogen atoms or C1-4 alkyl, C1-4 alkoxy, hydroxyl, trifluoromethyl, nitro or amino groups;
m is an integer 1 or 2;
n is an integer from 1 to 4;
and the physiologically acceptable salts thereof.
These compounds inhibit blood platelet aggregation, bronchoconstriction and vasoconstriction and thus of interest in the treatment of occlusive vascular diseases and asthma.
所述化合物为通式,其中 R¹ 为氢原子或 C1-4 烷基;R² 为萘基、噻吩基或 β-苯乙烯基或 Ar(CH₂)p- 基团,其中 p 为零或 1 至 3 的整数,Ar 为苯基或被一个或多个卤素原子或 C1-4 烷基、C1-4 烷氧基、羟基、三氟甲基、硝基或氨基取代的苯基;m 为 1 或 2 的整数;n 为 1 至 4 的整数;及其生理上可接受的盐类。 这些化合物可抑制血小板聚集、支气管收缩和血管收缩,因此在治疗闭塞性血管疾病和哮喘方面具有重要意义。
