MT(1) and MT(2) affinities, whereas the 4-nitro isomer (5) shows very high affinity (nanomolar) and selectivity for the MT(3) binding sites. N-Methylation of the indole nucleus of compound 5 potentiates these effects and affords the most potent and selective MT(3) ligand (17). The 2-iodo derivatives (12 and 10) of compounds 5 and 17 have also been synthesized to evaluate their binding profile with a
这项研究的目的是合成褪黑素能亚型受体的选择性配体,以阐明褪黑激素的生理作用(N-乙酰基-5-甲氧基色胺,1)。因此,我们首先研究了硝基取代基在吲哚杂环的4、6或7位中的作用。与褪黑激素相比,在6或7位(6和22)进行硝化的类似物失去MT(3),但保留良好的MT(1)和MT(2)亲和力,而4-硝基异构体(5)显示MT(3)结合位点的非常高的亲和力(纳米)和选择性。化合物5的吲哚核的N-甲基化作用增强了这些作用,并提供了最有效和最具选择性的MT(3)配体(17)。
