The invention concerns novel 1-benzyl-1,2,5,6-tetrahydropyridine-3-carboxylic acid derivates of the tormuta:-
wherein R1 is hydroxy, amino, (1-4C)alkylamino, di-[(1-4C)alkyl]amino, benzyloxy optionally substituted by halogeno, or (1-6C)alkoxy optionally substituted by (1- '4C)alkoxy, morpholino or di-[(1-4C)alkyl]amino; and benzene ring A bears one or two substituents selected from halogeno, (1-4C)alkyl, cyano, carboxamido, trifluoromethyl and hydroxy; and their pharmaceutically acceptable salts; together with pharmaceutical compositions thereof; and analogy processes for their manufacture.
The compounds of formula I are inhibitors of the aggregation of blood platelets and may be of application in the treatment or prophylaxis of thrombosis or occlusive vascular disease. A representative compound of the invention is 1-(2-chlorobenzyl)-1,2,5,6-tetrahydropyridine -3-carboxylic acid.
本发明涉及新型 1-苄基-1,2,5,6-四氢吡啶-3-羧酸衍生物,其结构式为:- 1-苄基-1,2,5,6-四氢吡啶-3-羧酸衍生物
其中 R1 是羟基、氨基、(1-4C)烷基氨基、二[(1-4C)烷基]氨基、任选被卤素取代的苄氧基或任选被(1-'4C)烷氧基取代的(1-6C)烷氧基、吗啉基或二[(1-4C)烷基]氨基;和苯环 A 带有一个或两个选自卤素、(1-4C)烷基、氰基、羧酰胺基、三氟甲基和羟基的取代基;及其药学上可接受的盐;连同其药物组合物;以及类比的制造工艺。
式 I 的化合物是血小板聚集的抑制剂,可用于治疗或预防血栓形成或闭塞性血管疾病。本发明的代表性化合物是 1-(2-氯苄基)-1,2,5,6-四氢吡啶-3-羧酸。
