sigma 1 over sigma 2 receptor. The crystal structures of 2a and 2b were shown, by X-ray crystallography, to be similar except for the one torsional angle of their propylene parts. Quantitative structure-activity relationship study suggested the affinity of the compounds to the sigma 1 receptor was dependent on the electronic feature, Swain-Lupton's R or Sz that was derived by molecular orbital method
合成了一组在其苯基上具有不同取代基(R1,R2)的标题化合物,以发现σ受体结合亲和力。在这些化合物中,2b(R1 = R2 = Cl)具有最强的sigma 1结合活性,而2a(R1 = R2 = H,SA4503)对sigma 1的选择性比sigma 2受体高。通过X射线晶体学显示2a和2b的晶体结构相似,除了它们的丙烯部分具有一个扭转角。定量构效关系研究表明,化合物与sigma 1受体的亲和力取决于R1和R2的电子特征,即分子轨道方法衍生的Swain-Lupton R或Sz。
