The present invention relates to a novel class of halogenated tetraenyl prostaglandin compounds represented by the following general formula ##STR1## or a pharmaceutically acceptable salt thereof, wherein Y is --CH.dbd.CH-- or --CH.sub.2 --CH.sub.2 --; R.sub.1 is H or a lower alkyl of 1 to 6 carbons; n is an integer from 0 to 3; m is an integer from 0 to 3 and n+m=3; X is Cl or F provided that when X is Cl, n is 2 and m is 1; R.sub.2 and R.sub.3 are independently H, lower alkyl from 1 to 6 carbons, Cl, --CH.sub.2 Cl, --CH.sub.2 F, --CHCl.sub.2, --CCl.sub.3, or taken together form a cycloalkyl of 3 to 6 carbons; R.sub.4 is H, lower alkyl from 1 to 6 carbons, Cl, F or taken together with R.sub.3 form a cycloalkenyl of 4 to 6 carbons; and provided that at least one of --CH.sub.n X.sub.m, R.sub.2, R.sub.3 and R.sub.4 includes a chlorine or fluorine atom.
本发明涉及一种新型的卤代四烯基前列腺素化合物,其通式如下:##STR1## 或其药学上可接受的盐,其中,Y为--CH.dbd.CH--或--CH.sub.2--CH.sub.2--; R.sub.1为H或1至6个碳的低烷基;n为0至3的整数;m为0至3的整数,且n+m=3;X为Cl或F,但当X为Cl时,n为2,m为1;R.sub.2和R.sub.3独立地为H、1至6个碳的低烷基、Cl、--CH.sub.2Cl、--CH.sub.2F、--CHCl.sub.2、--CCl.sub.3,或共同形成3至6个碳的环烷基;R.sub.4为H、1至6个碳的低烷基、Cl、F或与R.sub.3共同形成4至6个碳的环烯基;并且至少包含--CH.sub.nX.sub.m、R.sub.2、R.sub.3和R.sub.4中的一个含有氯或氟原子。
