hebaines were designed, synthesized, and assayed, leading to the discovery of a benzylamine derivative (compound 4, SLL-039) as a highly selective and potent κ opioid agonist (κ, Ki = 0.47 nM, κ/μ = 682, κ/δ = 283), which was confirmed by functional assays in vitro and antinociceptive assays in vivo. The in vivo effect could be blocked by pretreatment with the selective κ antagonist nor-BNI. Moreover
有效和安全的镇痛药代表了对急,慢性疼痛的医疗需求未得到满足。设计,合成和分析了一系列N-环丙基甲基-7α-苯基-6,14-内乙基四氢北丁醚,从而发现了苄胺衍生物(化合物4,SLL-039),它是一种高度选择性和有效的κ阿片激动剂( κ,Ki = 0.47 nM,κ/μ= 682,κ/δ= 283),已通过体外功能测定和体内抗伤害感受测定得到证实。体内作用可以通过用选择性κ拮抗剂nor-BNI预处理来阻断。此外,与U50,488H相比,该化合物在其镇痛剂量下不会诱导镇静作用,这是κ阿片受体激动剂的常见剂量限制作用。
