The present invention relates to novel isomers of PGAs, PGDs, PGEs, PGFs, 6-keto-PGE.sub.1 s, 6-keto-PGF.sub.1 s, PGI.sub.2 s, 6,9.alpha.-nitrilo-PGI.sub.1 s and 6,9.alpha.-methano-PGI.sub.2 s, having a specific steric configuration, which are replaced by an alkyl (C.sub.1 to C.sub.8)-substituted cycloalkyl (C.sub.4 to C.sub.7) group in 1S,S) form, in 1S,R) form or in cis form at the 15-, 16- or 17-position of the PG skeleton, and, alkyl esters thereof, non-toxic salts thereof, non-toxic acid addition salts thereof and cyclodextrin clathrates thereof, possessing more potent PG-like pharmacological activity than other isomers.
本发明涉及一种新型的PGAs、PGDs、PGEs、PGFs、6-酮基-PGE1s、6-酮基-PGF1s、PGI2s、6,9α-亚硝基-PGI1s和6,9α-甲基-PGI2s的异构体,具有特定的立体构型,在PG骨架的15、16或17位点以1S,S)形式、1S,R)形式或顺式形式被烷基(C1至C8)取代的环烷基(C4至C7)群,以及其烷基酯、无毒盐、无毒酸加成盐和环糊精包合物,比其他异构体具有更强的PG样药理活性。
