pharmacophore hypothesis which was consistent with the affinity and selectivity measured at 5-HT1D and 5-HT2A receptors. This pharmacophore is composed of a protonated amine site, an aromatic site, a hydrophobic pocket, and two hydrogen-bonding sites. A "selectivity site" was also identified which, if occupied, induced sensitivity for 5-HT1D over 5-HT2A in this series of molecules. The development and use
描述了一系列对5-HT1D具有药理活性的新型5-取代色胺和其他单胺受体的设计和合成。合成了N位和C位连接的(主要是乙内酰脲)类似物在5位上的结构修饰,并利用其药理活性推导了5-HT1D和5-HT2A受体亚型的显着空间和静电需求。计算了活性分子的构象,当它们重叠时,提出了药效基团假说,该假说与在5-HT1D和5-HT2A受体上测得的亲和力和选择性一致。该药效团由质子化的胺位点,芳族位点,疏水口袋和两个氢键位组成。还确定了一个“选择性位点”,如果被占领,在这一系列分子中对5-HT1D的敏感性高于5-HT2A。描述了药效团模型在化合物设计中的开发和使用。另外,讨论了有效口服吸收所需的分子大小和疏水性的物理化学约束。利用药效团模型结合分子大小和log DpH7.4的物理化学约束条件,导致了311C90(6)的发现,311C90是一种新型的选择性5-HT1D激动剂,具有良好的口服吸收能力,可用于治疗偏头痛。
