In the search for nicotinic acetylcholine receptor (nAChRs) agonists with a selective affinity for the homomeric α7 channels, we carried out the virtual screening of a test set of potential nicotinic ligands, and adopted a simplified MM-PBSA approach to estimate their relative binding free energy values. By means of this procedure, previously validated by a training set of compounds, we reached a realistic
在寻找对同型α7通道具有选择性亲和力的烟碱乙酰胆碱受体(nAChRs)激动剂时,我们对潜在的烟碱配体测试集进行了虚拟筛选,并采用简化的MM-PBSA方法估计其相对游离结合力。能量值。通过该程序,该程序先前已通过一组训练的化合物验证,我们在计算精度和计算速率之间达成了现实的折衷方案,并挑选出一小组新颖的结构相关衍生物,其特征在于对α7亚型的有希望的理论亲和力。其中,合成了五种新化合物,并在神经元α7和α4β2nAChRs的结合实验中进行了测定。
