A novel series of tetrahydroisoquinoline quaternary derivatives 4 were synthesized as peripheral κ-opioid receptor agonists. All the target compounds were evaluated in κ-opioid receptor binding assays, and compounds 4l, 4m, and 4n exhibited high affinity for κ-opioid receptor. Furthermore, compound 4l (κKi=0.94nM) produced potent antinociceptive activity in the mouse acetic acid-induced writhing assay
合成了一系列新的四氢异喹啉季衍生物4作为外围的κ阿片受体激动剂。所有目标化合物均通过κ阿片受体结合试验进行了评估,化合物4l,4m和4n对κ阿片受体表现出高亲和力。此外,化合物4l(κKi= 0.94nM)在小鼠乙酸诱导的扭体试验中产生了强大的抗伤害感受活性,镇静性副作用低于母体化合物MB-1c。
