A novel series of melatonin receptor ligands, characterized by a N-(substituted-anilinoethyl)amido scaffold, along with preliminary structure-activity relationships (SARs), is presented. MT1 and MT2 receptor binding affinity and intrinsic activity have been modulated by the introduction of different substituents on the aniline nitrogen, on the benzene ring, and on the amide side chain. Modulation of
提出了一系列新型的褪黑激素受体配体,其特征在于N-(取代的苯胺基乙基)酰胺基支架,以及初步的结构-活性关系(SAR)。通过在苯胺氮,苯环和酰胺侧链上引入不同的取代基,可以调节MT1和MT2受体的结合亲和力和内在活性。通过应用先前开发的SAR模型已经实现了新合成化合物的固有活性和MT2选择性的调节,从而提供了具有不同结合和固有活性特征的化合物。具有庞大的ss-萘基的化合物3d表现为具有亚nM亲和力的MT2选择性拮抗剂。如在非选择性N-甲基-苯胺基激动剂3i中那样,取代基的尺寸减小增强了内在活性。
