Conformational analysis of the 3-benzylpiperidine in CCR3 antagonist clinical candidate 1 (BMS-639623) predicts that the benzylpiperidine may be replaced by acyclic, conformationally stabilized, anti-1,2-disubstituted phenethyl- and phenpropylamines. Ab initio calculations, enantioselective syntheses, and evaluation in CCR3 binding and chemotaxis assays of anti-1-methyl-2-hydroxyphenethyl- and phe
CCR3拮抗剂临床候选药物1(BMS-639623)中3-苄基哌啶的构象分析预测,苄基哌啶可能会被无环,构象稳定的抗1,2-二取代苯乙胺和苯丙胺取代。从头算,对映选择性合成,以及在CCR3结合和抗-1-甲基-2-羟基苯乙基和苯丙胺的CCR3拮抗剂的趋化性分析中进行评估,都支持这种构象相关性。
