o-anisic acid (7) to give the N-phenylpiperazine 8. This substance was converted via ethyl ester 10 to 1-[2-(hydroxymethyl)phenyl]-4-methyl-2-(2-thienyl)piperazine (3), which was cyclized with polyphosphate ester to a 5:1 mixture of 2 and 12. The antidepressant potential of 2 maleate (CGS 11049A) and 12 fumarate (CGS 15413A) were compared with that of mianserin hydrochloride in a variety of biochemical and
mianserin的两个含噻吩类似物的合成,即1,2,3,4,10,13b-六氢-2-甲基哌嗪并[1,2-a]噻吩并[2,3-c] [1]苯并ze庚因( 2),并描述了相应的[3,2-c]异构体(12)。合成的关键步骤是1-甲基-3-(2-噻吩基)哌嗪(4)的N-硫代衍生物与邻茴香酸的恶唑啉衍生物(7)的亲核芳族取代反应,得到N -苯基哌嗪8.该物质经乙酯10转化为1- [2-(羟甲基)苯基] -4-甲基-2-(2-噻吩基)哌嗪(3),将其与聚磷酸酯环化成5:将2和12的1种混合物在各种生化和药理测试系统中与2种马来酸酯(CGS 11049A)和12种富马酸酯(CGS 15413A)的抗抑郁潜力与盐酸米安色林的抗抑郁潜力进行了比较。这三种物质显示出大致相似的轮廓。但是,结果表明2和12与棉兰素相比更牢固地结合到中央突触前α受体。
