series of melatonin analogs obtained by the replacement of the ether methyl group with larger arylalkyl and aryloxyalkyl substituents was prepared in order to probe the melatonin receptors for MT1‐selectivity. The most MT1‐selective agents 11 and 15 were substituted with a Ph(CH2)3 or a PhO(CH2)3 group. Compounds 11 and 15 displayed 11.5‐fold and 11‐fold higher affinity for the MT1 receptors than for
制备了一系列通过用更大的芳烷基和芳氧基烷基取代基取代醚甲基获得的褪黑激素类似物,以探测褪黑激素受体的 MT1 选择性。大多数 MT1 选择性试剂 11 和 15 被 Ph(CH2)3 或 PhO(CH2)3 基团取代。化合物 11 和 15 对 MT1 受体的亲和力比对 MT2 亚型高 11.5 倍和 11 倍。有趣的是,在我们的结合测定中,11 和 15 显示出比参考配体二聚体阿戈美拉汀 1a 更高的 MT1 亲和力和选择性。
