of the nicotinic acetylcholine receptors. The results reveal that hydrogen bonding from both hydrogens on the protonated amine and from the pyridine nitrogen to a water molecule as well as van der Waals interactions between the substituent bearing the protonated amine and the receptor is of importance for ligand affinity. The combination of 3D-QSAR and homology modeling proved successful for the interpretation
在以前的计算研究结果的基础上,合成了一系列对烟碱乙酰胆碱受体α4β2亚型具有亲和力的哌嗪,二氮杂pan,重氮azo,重氮杂双环壬烷和重氮杂双环癸烷。使用GRID / GOLPE方法开发了预测性3D-QSAR模型(R2 = 0.94,Q2 = 0.83,SDEP = 0.34)。SAR是根据PLS系数的轮廓图和烟碱型乙酰胆碱受体的alpha4beta2亚型的同源性模型来解释的。结果表明,从质子化胺上的氢和从吡啶氮到水分子的氢键以及带有质子化胺的取代基和受体之间的范德华相互作用对于配体亲和力都是重要的。
