describes the synthesis and structure-activity relationships as kappa opioid analgesics of a novel class of 1-(arylacetyl)-2-(aminomethyl)piperidine derivatives. The active conformation of the pharmacophore, with a torsional angle (N1C2C7N8) of 60 degrees, was defined with computational studies and 1H NMR. A quantitative structure-activity relationship study of the arylacetic moiety substitution indicated
本文描述了新型的1-(芳基乙酰基)-2-(氨基甲基)哌啶衍生物的合成和构效关系,作为κ阿片类镇痛药。通过计算研究和1H NMR定义了具有60度扭转角(N1C2C7N8)的药效团的活性构象。芳香族部分取代的定量结构-活性关系研究表明,对位和/或间位存在吸电子和亲脂性取代基是良好的镇痛活性和κ亲和力所必需的。铅化合物(2S)-1-[((3,4-二氯苯基)乙酰基] -2-(吡咯烷-1-基甲基)哌啶盐酸盐和(2S)-1- [4-(三氟甲基)苯基]乙酰基] -2 -(吡咯烷-1-基甲基)哌啶盐酸盐的Kappa / mu选择性最高(分别为6500:1和4100:1)以及迄今为止鉴定出的最有力的(κκ0.24和0.57 nM)κ配体。在抗伤害感受的小鼠甩尾模型中,化合物14(ED50 = 0.05 mg / kg sc)的效力是吗啡的25倍,效力是标准Kappa配体U-50488的16倍。
