Pharmacol. 1988, 34, 42-53) and used to develop 3-dimensional quantitative structure-activity relationships (3-D QSARs) for these compounds at the 5-HT1A and 5-HT2 receptor sites, by the method of comparative molecular field analysis (CoMFA). Since the previous study included several conventional QSARs obtained by Hansch analysis, and the new compounds in some cases fall within the congeneric
合成了一系列新的3-(1,2,5,6-四氢吡啶-4--4-基)吲哚(4-THPI)衍生物,它们在5-HT1A和5-HT2血清素(5-已经确定了HT)受体亚型。新数据与先前报道的一组相关THPI类似物的结合数据相结合(Taylor等人,Mol。Pharmacol。1988,34,42-53),并用于建立三维定量结构-活性关系(3-通过比较分子场分析(CoMFA)方法,将这些化合物在5-HT1A和5-HT2受体位点的D QSARs)。由于先前的研究包括通过Hansch分析获得的几种常规QSAR,并且在某些情况下新化合物属于这些分析所用的同类系列,我们能够使用相同的训练和测试数据集直接比较CoMFA和Hansch分析的预测能力。两种方法对活动的实际预测的总体质量似乎大致相同,这是通过实际pKi值与预测pKi值之间的均方根(rms)残差进行评估的。一方面,Hansch分析最难预测的化合物是34、3
