property-based design of bioactive compounds. Impacts on amine basicity are very pronounced for the β-equatorial functional groups and parallel basicity-lowering effects known for acyclic amine derivatives. For β-axial functional groups, the basicity-lowering effects are generally decreased, with the nitrile group as the only exception. Basicity and lipophilicity modulations observed for β-axial functional
合成了13个5个取代的N-哌啶基-3-苯基哌啶衍生物的差向异构对,以探索碱性,亲脂性,水溶性和膜渗透性(通过与胺单元成直角的赤道或轴向位置)的立体定向调节。尽管此综合数据集可增强对影响碱性和亲脂性的多种因素的洞察力,但它填补了重要的知识空白,为基于特性的生物活性化合物设计提供了参考框架。β-赤道官能团对胺碱性的影响非常显着,无环胺衍生物已知降低平行碱度的作用。对于β轴官能团,降低碱度的作用通常会降低,其中腈基是唯一的例外。就分子内氢键,偶极相互作用和特殊的溶剂化作用而言,针对β轴官能团观察到的碱度和亲脂性调节非常多样且合理化。参照亲脂性讨论了水溶性和(人工)膜渗透性。
