The synthesis and H3 receptor ligand of a new series of lactam derivatives are reported. The new compounds were evaluated in vitro in H3 and H1 receptor-binding assays. The structure-activity relationship led us to the promising derivative 2-methyl-7-(3-morpholinopropoxy)-3,4-dihydroisoquinolin-1(2H)-one (11). The compound with highest affinity and greatest selectivity were further profiled, In addition
报道了一系列新的内酰胺衍生物的合成和H3受体配体。在H3和H1受体结合试验中对新化合物进行了体外评估。构效关系使我们获得了有前途的衍生物2-甲基-7-(3-吗啉代丙氧基)-3,4-二氢异喹啉-1(2H)-一(11)。进一步分析了具有最高亲和力和最大选择性的化合物。此外,化合物11在福尔马林试验中发挥了剂量依赖性的抗伤害感受作用。这些特征表明有效和选择性的化合物11可以是用于疼痛治疗的有效候选物。
