This invention relates to 4,5,6,7-tetrahydro-thieno[2,3-c]- and [3,2-c]-pyridines having the formulae: ##STR1## in which R.sup.1 is selected from hydrogen and halogen; R.sup.2 is selected from hydrogen and hydroxy; R.sup.3 and R.sup.4, which may be the same or different, are each selected from hydrogen, C.sub.1-6 alkyl, phenylalkyl having 1-6 carbon atoms in the alkyl moiety, and phenyl-C.sub.1-6 alkyl substituted on the phenyl nucleus with at least a substituent selected from halogen, C.sub.1-6 alkyl, C.sub.1-6 alkoxy, hydroxy, nitro, cyano and trifluoromethyl; and their acid addition salts. Said derivatives possess therapeutically useful anti-sludge, anti-thrombosis and blood-platelet aggregation inhibiting properties.
本发明涉及具有以下式子的4,5,6,7-四氢噻吩[2,3-c]-和[3,2-c]-吡啶:##STR1## 其中R.sup.1从氢和卤素中选择;R.sup.2从氢和羟基中选择;R.sup.3和R.sup.4,可以相同也可以不同,分别从氢、C.sub.1-6烷基、苯基烷基(烷基中含有1-6个碳原子)、苯基-C.sub.1-6烷基中选择,苯基在苯环上至少有一个取代基,所述取代基从卤素、C.sub.1-6烷基、C.sub.1-6烷氧基、羟基、硝基、氰基和三氟甲基中选择;以及它们的酸加成盐。这些衍生物具有治疗上有用的抗沉淀、抗血栓形成和抑制血小板聚集的特性。
