leads ((R)-(+)-hyoscyamine and (p-chlorophenyl)propionic acid alpha-tropanyl ester), which show analgesic and nootropic activities as a consequence of increased central presynaptic ACh release, are reported. 2-Phenoxy- and 2-(phenylthio)alkanoic acid esters showed the best results. Several members of these classes possess analgesic properties which are comparable to that of morphine and at the same time
据报道,对铅的进一步修饰((R)-(+)-水苏胺和(对-氯苯基)丙酸α-托帕尼酯),由于增加的中央突触前ACh释放而显示出止痛和促智活性。2-苯氧基-和2-(苯硫基)链烷酸酯显示了最佳结果。这些类别中的几个成员具有与吗啡相当的镇痛作用,同时能够逆转由二环胺引起的健忘症。证实作用机制是由于中央毒蕈碱突触中ACh释放的增加所致,控制ACh释放的自体和异体受体极有可能参与其中。根据(R)-(+)-硫辛胺获得的结果,镇痛活性与立体化学有关,因为R-(+)-对映异构体总是比相应的S-(-)-one更有效。根据其效力和急性毒性,选择化合物(+/-)-28(SM21)和(+/-)-42(SM32)进行进一步研究。
