A compound of formula I
wherein X, Y, X′ & Y′ are selected from hydrogen, halogen, substituted or unsubstituted alkyl (linear, branched or cyclo), aryl, alkyloxy and haloalkyl group; R1, R2, R3 & R4 are selected from hydrogen, substituted or unsubstituted alkyl groups (linear, branched or cyclo), aryl, heteroaryl groups or aralkyl groups, heterocycles containing one or more of hetero atoms (viz., N, S, O), substituted or unsubstituted alkenyl or alkynyl groups of carbon 2 to 6; wherein the substituents R1 & R2 on the piperazinyl moiety are either syn or anti to each other and optionally R3 and R4 together with the carbons to which they are attached form a monocyclic saturated or aryl or substituted aryl or heteroaryl or substituted heteroaryl ring containing one or more hetero atoms selected from N, S and O with a ring size ranging from 3 to 6; with a proviso that when R3 & R4 together do not form part of a ring they may exist in either E or Z configuration; R5 is (CH2)n—O—CH2—CO-Z wherein n is 1 to 6; Z is selected from OH, OR, NRR′, N(OR)R′, N(R)—N(R)R′and
wherein R & R′ are selected from hydrogen, substituted or unsubstituted alkyl groups (linear, branched or cyclo), aryl, heteroaryl groups or aralkyl groups, heterocycles containing one or more of hetero atoms (viz., N, S, O), substituted or unsubstituted alkenyl or alkynyl groups of carbon 2 to 6; and B is selected from —(CH2)n-(n is 1 to 6) and —(CH2)x-D-(CH2)y where D is O, NR, S or SO2, x and y are independently 1 to 6; and m is selected from 1 to 6; and pharmaceutically acceptable salts thereof.
化合物I的化学式,其中X、Y、X'和Y'从氢、卤素、取代或未取代的直链、支链或环烷基、芳基、烷氧基和卤代烷基中选择;R1、R2、R3和R4从氢、取代或未取代的直链、支链或环烷基、芳基、杂芳基或芳基烷基、含有一个或多个杂原子(即N、S、O)的杂环、取代或未取代的碳2至6的烯丙基或炔基中选择;其中哌嗪基上的取代基R1和R2可以是同构或异构的,可选地R3和R4与它们连接的碳原子一起形成一个饱和的单环、芳基、取代芳基、杂芳基或取代杂芳基环,其中包含一个或多个从N、S和O中选择的杂原子,环大小在3到6之间;但当R3和R4不形成环的一部分时,它们可以存在于E或Z构型中;R5为(CH2)n-O-CH2-CO-Z,其中n为1到6;Z从OH、OR、NRR'、N(OR)R'、N(R)-N(R)R'和中选择,其中R和R'从氢、取代或未取代的直链、支链或环烷基、芳基、杂芳基或芳基烷基、含有一个或多个杂原子(即N、S、O)的杂环、取代或未取代的碳2至6的烯丙基或炔基中选择;B从—(CH2)n-(n为1到6)和—(CH2)x-D-(CH2)y中选择,其中D为O、NR、S或SO2,x和y独立地为1到6;m从1到6中选择;以及其药学上可接受的盐。
