A series of N-sec- and N-tert-alkylnormorphines was synthesized and evaluated for analgesic potency, antagonist activity, and opiate receptor binding. Computer-assisted conformational analysis profiles were utilized to assist in the selection of compounds for synthesis and correlation of receptor events with in vivo observations. N-tert-Alkylnormorphines 5a-c were devoid of agonist activity; however
合成了一系列的N-仲和N-叔烷基
去甲吗啡,并评估了其止痛效果,拮抗剂活性和阿片受体结合。利用计算机辅助的构象分析概况来协助化合物的选择,以合成并与体内观察相关的受体事件。N-叔烷基正
吗啡5a-c没有激动剂活性;然而,一些仲烷基类似物表现出有趣的混合激动剂-
抑制剂作用。N-仲丁基-和N-(α-甲基)的
吗啡被分为R和S异构体,表现出定量的药理学差异。N-仲丁基S异构体10a的镇痛作用类似于
吗啡,具有纳洛啡样拮抗剂活性。初步测试表明该化合物对身体的依赖性很小。
