affect H1 affinity. In contrast, analogous meta-substitution for the 6-APTs increases H1 affinity up to 100-fold. The new APTs do not activate H1 receptor-linked intracellular signaling and apparently are competitive H1 antagonists. A new model that establishes structural parameters for binding to the human H1 receptor by APTs and other ligands was developed using 3-D QSAR (CoMFA). The model predicts
本文报道了一系列新的(+/-)-2-二甲基氨基-5和6-苯基-1,2,3,4-四氢萘衍生物(5-和6-APT)的合成,以及相应的亲和力,针对人类组胺H1受体的药物设计的功能活性和分子模型研究。5-APT具有比内源性激动剂组胺高2至4倍的H1受体亲和力。5-APT侧链苯基部分上的间位取代基的化学性质不会显着影响H1亲和力。相反,6-APT的类似间位取代将H1亲和力提高了100倍。新的APT不会激活H1受体相关的细胞内信号传导,显然是竞争性H1拮抗剂。使用3-D QSAR(CoMFA)开发了一种新模型,该模型建立了通过APT和其他配体与人H1受体结合的结构参数。与先前报道的模型相比,该模型预测H1配体的结合具有更高的外部可预测性。还检查了APT对人血清素5-HT2A和5-HT2C受体的活性,这在系统发育上与H1受体密切相关。5-APT和m-Cl-6-APT被确定为选择性激活5-HT2C受体的新
