and N-(2,3-dichlorophenyl)piperazine analogs were prepared and their affinities for dopamine D(2), D(3), and D(4) receptors were measured in vitro. Binding studies were also conducted to determine if the compounds bound to sigma (sigma(1) and sigma(2)) and serotonin (5-HT(1A), 5-HT(2A), 5-HT(2B), 5-HT(2C), 5-HT(3), 5-HT(4), 5-HT(5), 5-HT(6), and 5-HT(7)) receptors. The results of the current study revealed
制备了一系列的N-(2-甲氧基苯基)哌嗪和N-(2,3-二氯苯基)哌嗪类似物,并在体外测量了它们对多巴胺D(2),D(3)和D(4)受体的亲和力。还进行了结合研究以确定化合物是否结合sigma(sigma(1)和sigma(2))和血清素(5-HT(1A),5-HT(2A),5-HT(2B),5- HT(2C),5-HT(3),5-HT(4),5-HT(5),5-HT(6)和5-HT(7))受体。当前研究的结果表明,许多化合物(12b,12c,12e和12g)对D(3)具有高亲和力(D(3)受体的K(i)范围从0.3到0.9 nM),而D (2)(D(2)受体的K(i)在40到53 nM之间)和log P值,表明它们应该容易越过血脑屏障(log P = 2.6-3.5)。在这项研究中评估的所有化合物都对5-羟色胺5-HT(1A)受体具有高亲和力。
