Dihydropyridine derivatives represented by formula (I):
wherein Ri, R2, R3 and R6, which may be the same or different, each represents an alkyl group, a cycloalkyl group or an alkoxyalkyl group; R4 and R5, which may be the same or different, each represents a hydrogen atom, a halogen atom, a nitro group, a halogenated alkyl group, an alkylsulfonyl group, a halogenated alkoxy group, an alkylsulfinyl group, an alkyl group, a cycloalkyl group, an alkoxy group, a cyano group, an alkoxycarbonyl group or an alkylthio group (provided that R4 and R5 are not hydrogen atoms at the same time); X represents a vinylene group or an azomethine group; A and B are each an alkylene group or an alkenylene group; R7 and Rs, which may be the same or different, each represents a hydrogen atom, an alkyl group, an alkenyl group, an aralkyl group, an aryl group, or a heterocyclic group (provided that R7 and R8 may combine with the adjacent nitrogen atom to form a hetero ring), and acid addition salts of the dihydropyridine derivative of formula (I), and use of the same in the preparation of a medicament for the treatment of vascular disorders.
由式(I)代表的二氢吡啶衍生物:
其中 Ri、R2、R3 和 R6(可以相同或不同)各自代表一个烷基、一个环烷基或一个烷氧基烷基;R4 和 R5(可以相同或不同)各自代表氢原子、卤素原子、硝基、卤代烷基、烷基磺酰基、卤代烷氧基、烷基亚磺酰基、烷基、环烷基、烷氧基、氰基、烷氧羰基或烷硫基(条件是 R4 和 R5 不能同时为氢原子);X 代表乙烯基或偶氮亚甲基;A 和 B 分别是亚烷基或烯基;R7和Rs可以相同或不同,各自代表氢原子、烷基、烯基、芳烷基、芳基或杂环基(条件是R7和R8可以与相邻的氮原子结合形成杂环),以及式(I)的二氢吡啶衍生物的酸加成盐,并将其用于制备治疗血管疾病的药物。
