The invention relates to carbacyclins of general Formula I ##STR1## wherein R.sub.1 is the residue CH.sub.2 OH or ##STR2## with R.sub.2 meaning a hydrogen atom, an alkyl, cycloalkyl, aryl residue, a ##STR3## or heterocyclic residue, or R.sub.1 is the residue ##STR4## with R.sub.3 meaning an alkanoyl or alkanesulfonyl residue of respectively 1-10 carbon atoms or the residue R.sub.2, or R.sub.1 is the residue ##STR5## wherein m is the number 1 or 2, X is an oxygen atom or a CH.sub.2 -group, A is a trans--CH.dbd.CH- or --.tbd.C--group, W is a free or functionally modified hydroxymethylene group wherein the OH-group can be in the .alpha.- or .beta.- position, n is the number 1, 2, or 3, D is a straight-chain alkylene group of 1-5 carbon atoms, E is a --C.tbd.C---bond or a --CR.sub.6 =CR.sub.7 --group wherein R.sub.6 and R.sub.7 are different from each other and mean a hydrogen atom or an alkyl group of 1-5 carbon atoms or a hydrogen atom or a halogen atom, preferably chlorine, R.sub.4 is an alkyl, cycloalkyl, or optionally substituted arly group, or a heterocyclic group, R.sub.5 is a free or functionally modified hydroxy group, and if R.sub.2 means a hydrogen atom, the salts thereof with physiologically compatible bases; to processes for the preparation thereof, and to the use thereof as blood-pressure-lowering agents.
本发明涉及一般式I的碳环素,其中R1是残基CH2OH或 ##STR2## R2表示氢原子,烷基,环烷基,芳基残基, ##STR3## 或杂环残基,或R1是残基 ##STR4## 其中R3分别为1-10个碳原子的脂肪酰基或烷基磺酰基残基或残基R2,或R1是残基 ##STR5## 其中m是数字1或2,X是氧原子或CH2-基团,A是反式-CH=CH-或-.tbd.C-基团,W是自由或功能修饰的羟甲基基团,其中OH基团可以处于.alpha.-或.beta.-位置,n是数字1,2或3,D是1-5个碳原子的直链烷基基团,E是--C.tbd.C---键或--CR6=CR7--基团,其中R6和R7不同且表示1-5个碳原子的氢原子或烷基基团或氢原子或卤原子,优选为氯,R4是烷基,环烷基或可选取代的芳基基团或杂环基团,R5是自由或功能修饰的羟基团,如果R2表示氢原子,则与生理兼容的碱盐,其制备过程以及作为降低血压药物的用途。
