Substituted thienyl-acetic acid esters of the formula: ##STR1## in which R.sub.1 and R.sub.2 each, independently is H, CH.sub.3, C.sub.2 H.sub.5, C.sub.3 H.sub.7, OCH.sub.3, SCH.sub.3, Cl Br or NO.sub.2, R.sub.3 is phenyl or cyclohexyl and R.sub.4 is H, or R.sub.3 and R.sub.4 together are cyclohexylidene, n is 2 or 3, and A is monoalkylamino or dialkylamino, each alkyl radical having 1 to 4 carbon atoms, or amino derived from a cycloalkylamine of 5 to 7 chain members which may contain an additional hetero-atom, provided that each of R.sub.1 and R.sub.2 is not H if R.sub.3 is phenyl or cyclohexyl and R.sub.4 is H, racemates, optical isomers, and their pharmaceutically acceptable acid addition salts and quaternary ammonium salts obtained with alkyl halides, have marked activity as peripheral vasodilators, platelet aggregation inhibitors, spasmolytic agents, coronary and cerebral vasodilators, and papaverine-like activity.
公式为:##STR1##中的噻吩乙酸酯,其中R.sub.1和R.sub.2各自独立地为H、CH.sub.3、C.sub.2 H.sub.5、C.sub.3 H.sub.7、OCH.sub.3、SCH.sub.3、Cl、Br或NO.sub.2,R.sub.3为苯基或环己基,R.sub.4为H,或者R.sub.3和R.sub.4一起为环己基亚甲基,n为2或3,A为单烷基胺或双烷基胺,每个烷基基团含有1至4个碳原子,或者来自含有5至7个链成员的环烷胺的氨基,该环烷胺可能包含额外的杂原子,前提是如果R.sub.3为苯基或环己基且R.sub.4为H,则R.sub.1和R.sub.2中的每一个都不是H,其外消旋体、光学异构体及其与烷基卤化物得到的药用可接受酸盐和季铵盐具有显著的周围血管扩张剂、血小板聚集抑制剂、解痉剂、冠脉和脑血管扩张剂以及类似阿片类的活性。
