N-[4-methoxy-3-(4-methylpiperazin-1-yl)phenyl] 2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)biphenyl-4-carboxamide (1; GR127935) as potent and selective 5-HT(1B/1D) antagonists were synthesized and evaluated pharmacologically. Their receptor binding profiles were comparable to that of 1. The 1,3,4-oxadiazole isomer 2 and the 4'-aminocarbonyl and 4'-amidinyl analogues (9 and 10) of 1 had higher affinities at the
N- [4-甲氧基-3-(4-甲基哌嗪-1-基)苯基] 2'-甲基-4'-(5-甲基-1,2,4-恶二唑-3-基的一系列新类似物)联苯胺4-羧酰胺(1; GR127935)作为有效的和选择性的5-HT(1B / 1D)拮抗剂,并进行了药理学评估。它们的受体结合特性与1相当。1,3,4-恶二唑异构体2和1的4'-氨基羰基和4'-ami基类似物(9和10)在大鼠5-HT( 1B)受体(IC(50)分别为0.93、1。3和0.5 nM)和5-HT(1D)小牛受体(IC(50)分别为37、10和3 nM)比1(大鼠5-HT(1B)和小牛5-HT(1D)受体分别为1.6和52 nM。在5-HT(1B / 1D)拮抗特性的功能性体外测试中,2,9,9,10,11b(2的O-去甲基衍生物),13a(2的O-甲基磺酰基类似物),16和16(与2个磺酰胺连接基不同)对豚鼠皮层中K(+)诱导的5-HT释放的作
