Certain substituted phenylpiperazine compounds suitable for use an antihypertensive agents are described, as are processes for their preparation. The novel compounds have the formula:
wherein A is
n is 2, 3 or 4; and R1 is a hydrogen atom, an alkyl radical having from one to six carbon atoms or an alkoxy radical having from one to six carbon atoms; or a pharmaceutically acceptable salt thereof; with the provisos that: when A is A1 and n is 3, R1 is not 3-OCH3; when A is A2 and n is 3, R1 is not 2-OCH3 or 4-OCH3; and, when A is A2 and n is 4, R1 is not 4-CH3 or 4-OCH3.
本文描述了某些适用于抗高血压药物的取代苯基哌嗪化合物及其制备方法。这些新型化合物的化学式如下
其中 A 是
n为2、3或4;且R1为氢原子、具有1至6个碳原子的烷基或具有1至6个碳原子的烷氧基;或其药学上可接受的盐;但条件是:当A为A1且n为3时,R1不是3-OCH3;当A为A2且n为3时,R1不是2-OCH3或4-OCH3;且当A为A2且n为4时,R1不是4-CH3或4-OCH3。
