Novel compounds represented by the formula:
wherein R₁ represents an alkyl group having 1 to 3 carbon atoms, R₂ represents an amino group or a group of formula
in which R₄ represents an alkyl group having 1 to 3 carbon atoms, R₅ represents an alkyl group having 1 to 3 carbon atoms or may combine with R₆ to form a five or six membered ring containing 4 to 5 carbon atoms, R₆ represents a hydrogen atom or may combine with R₅ to form a five or six membered ring containing 4 to 5 carbon atoms, R₃ represents a hydrogen atom, an alkyl group having 1 to 3 carbon atoms or a halogen atom, X represents a carbonyl group or a methylene group, Y represents a sulfur atom or a vinylene group and pharmaceutically acceptable salts thereof which exhibit a vasodilating activity and inhibitory activity for platelet aggregation.
Thus, they are useful as therapeutic agents for treatment of angina pectoris, hypertension, thrombosis and the like.
由以下式子表示的新型化合物
其中 R₁ 代表具有 1 至 3 个碳原子的烷基,R₂ 代表氨基或式中的基团
其中 R₄ 代表具有 1 至 3 个碳原子的烷基,R₅ 代表具有 1 至 3 个碳原子的烷基或可与 R₆ 结合形成含有 4 至 5 个碳原子的五或六元环,R₆ 代表氢原子或可与 R₅ 结合形成含有 4 至 5 个碳原子的五或六元环、R₃代表氢原子、具有 1 至 3 个碳原子的烷基或卤素原子,X 代表羰基或亚甲基,Y 代表硫原子或乙烯基及其药学上可接受的盐,它们具有血管扩张活性和血小板聚集抑制活性。
因此,它们可用作治疗心绞痛、高血压、血栓形成等疾病的治疗剂。
