200-fold selectivity for the h5-HT1D receptor over the h5-HT1B receptor. Unlike other h5-HT1D-selective series, several propylpiperazines demonstrate good oral bioavailability. The optimum compound was 1-(3-[5-(1,2, 4-triazol-4-yl)-1H-indol-3-yl]propyl)-4-(2-(3-fluorophenyl)ethyl)p ipe razine (7f) which has excellent selectivity for h5-HT1D receptors over other 5-HT receptor subtypes and good oral bioavailability
临床上有效的抗偏头痛药物,例如舒马曲坦,对h5-HT1D和h5-HT1B受体具有相似的亲和力。在寻找作为抗偏头痛药物的h5-HT1D选择性激动剂中,合成了一系列新的3-(丙基哌嗪基)吲哚并在h5-HT1D和h5-HT1B受体上进行了评估。这类化合物为亚纳摩尔级,完全有效的h5-HT1D激动剂提供了比h5-HT1B受体高200倍的选择性。与其他h5-HT1D选择系列不同,几种丙基哌嗪具有良好的口服生物利用度。最佳化合物为1-(3- [5-(1,2,4-三唑-4-基)-1H-吲哚-3-基]丙基)-4-(2-(3-氟苯基)乙基)p ipe raazine(7f)对h5-HT1D受体具有优于其他5-HT受体亚型的选择性,并且在三种物种中具有良好的口服生物利用度。
