Substituted benzoic acid esters of 1-methyl-4-piperidinol showed analgesic activity when assayed by the mouse hot-plate methods, the more potent ones falling in the morphine-codeine range. To understand how substituents on the aromatic ring affect the analgesic potency, quantitative structure-activity correlations were carried out on a series of 44 derivatives. Among the various substituent parameters
当用小鼠热板法测定时,被1-甲基-4-哌啶醇取代的苯甲酸酯显示出止痛活性,更有效的属于吗啡-可待因范围。为了理解芳环上的取代基如何影响止痛效果,对一系列44种衍生物进行了定量的构效关系。在研究中包括的各种取代基参数中,间位和对位的Lortho(邻位取代基的长度)和B1(取代基的最小宽度)或E8与效价呈负相关,而亲脂性(尤其是pi meta)和能力氢键受体的作用增强了效力。根据QSAR结果,为最佳活性定义了苯基的取代模式。
