Disclosed are a piperazine compound of the formula below or a pharmaceutically acceptable salt thereof, medical uses thereof, and processes for preparing the same: ##STR1## wherein each of R and R' is --OH, a lower alkoxy, a halo, H, a di(lower alkyl) hydrogenphosphate residue or a group --OR" (R" is an aralkyl group, etc.), etc., Y is --CH.dbd.CH-- or --(CH.sub.2).sub.m -- (m is 0, 1 or 2), and Y.sub.1 is a group of the formula ##STR2## (wherein A is --NH-- or --O--, A.sub.1 is a methylene or a carbonyl, n is 6-20, X is --OH, H or a lower alkoxycarbonyl, and X.sub.1 is an optionally halo-substituted phenyl or H) or a group of the formula ##STR3## (wherein X and n are as defined above), provided that when Y.sub.1 is the group of the formula (3), each of R and R' is an --OH group.
本发明涉及下式的哌嗪化合物或其药学上可接受的盐,其医药用途以及其制备方法:##STR1## 其中R和R'中的每一个都是--OH,较低的烷氧基,卤素,H,二(较低的烷基)氢氧根残基或--OR"(其中R"是芳基烷基等),Y是--CH.dbd.CH--或--(CH.sub.2).sub.m--(m为0、1或2),Y.sub.1是下式的基团##STR2##(其中A是--NH--或--O--,A.sub.1是亚甲基或羰基,n为6-20,X是--OH,H或较低的烷氧羰基,X.sub.1是一个可选的卤代苯基或H)或下式的基团##STR3##(其中X和n的定义如上),但当Y.sub.1是式(3)的基团时,R和R'中的每一个都是--OH基团。
