The synthesis and intravenous analgesic activity of a series of 3-methyl-4-(N-phenyl amido)piperidines, entries 34-79, is described. The methoxyacetamide pharmacophore produced a series of compounds with optimal analgesic potency and short duration of action. cis-42 was 13,036 times more potent than morphine and 29 times more potent than fentanyl; however, the corresponding diastereomer 43 was only
描述了一系列3-甲基-4-(N-苯基酰胺基)哌啶(条目34-79)的合成和静脉镇痛活性。甲氧基乙酰胺药效基团产生了一系列具有最佳止痛效果和较短作用时间的化合物。顺式42的功效是吗啡的13036倍,是芬太尼的29倍。然而,相应的非对映异构体43的效力分别仅为2778和6倍。化合物40、43、47和57具有极短的作用;它们均具有约2分钟的作用时间,相当于小鼠热板试验中芬太尼作用时间的1/5,相当于ED50镇痛剂量的2倍。在表现出出色镇痛活性的许多化合物中,作用持续时间是选择候选药物进行进一步药理研究的主要因素之一。目前,顺式-1- [2-(4-乙基-4,5-二氢-5-氧代-1H-四唑-1-基)乙基] -3-甲基yl-4- [N-处于平衡状态2-氟苯基)甲氧基乙酰胺基]哌啶盐酸盐(40)(Anaquest,A-3331.HCl,Brifentanil)正在临床评估中。具有作用时间短的阿片类镇痛药
