5-HT7 receptor (5-HT7R) agonists and antagonists have been reported to be used for treatment of neuropathic pain and depression, respectively. In this study, as a novel scaffold for 5-HT7R modulators, we designed and prepared a series of biphenyl-3-yl-methanamine derivatives with various amino groups. Evaluation of functional activities as well as binding affinities of the title compounds identified
据报道,5-HT 7受体(5-HT 7 R)激动剂和拮抗剂分别用于治疗神经性疼痛和抑郁症。在这项研究中,作为5-HT 7 R调节剂的新型支架,我们设计并制备了一系列具有各种氨基的联苯-3-基-甲胺衍生物。对标题化合物的功能活性和结合亲和力的评估确定了部分激动剂(EC 50 = 0.55-3.2μM)和完全拮抗剂(IC 50 = 5.57–23.1μM),具体取决于氨基取代基。分子对接研究表明,基于配体的功能活性从激动剂到拮抗剂的转换是由于氨基的大小以及与5-HT 7 R的不同结合方式所致。特别是配体与5-HT的Arg367相互作用已显示7 R区分激动剂和拮抗剂。在药效基团模型研究中,两个不同的药效基团模型可以判断配体是激动剂还是拮抗剂。总之,这项研究为设计具有针对5-HT 7 R的选择性激动或拮抗特性的新型化合物提供了有价值的信息。
