as an anchor by fixing the pendant phenyl group in a desirable orientation for receptor binding, and (iii) since compounds with aromatic rings (2) and those with aliphatic rings (3) as ring B both show good potency, this ring does not seem to be essential for receptor recognition. Among the compounds synthesized, the tetrahydropyridine derivatives 3a, 3b and 3f exhibited excellent inhibitory effects
在异喹诺酮(1a)和吡啶并[3,4-b]吡啶(2a)的A和B环上修饰的各种N- [3,5-双(三氟甲基)苄基] -N-甲基氨基甲酰基杂环(1、2和3)制备细胞核并评估NK1受体拮抗活性。关于该系列的构效关系研究以及构象分析表明,(i)对于A环,6元杂环优于5元杂环(效力相差约300倍),(ii) 6元环似乎可以通过将侧基苯基固定在受体结合所需的方向上来充当锚,并且(iii)因为带有芳环(2)和带有脂环(3)作为环B的化合物都显示具有良好的效能,该环似乎并不是受体识别所必需的。在合成的化合物中,
