types. In particular, derivatives B2 and C1 (RSC4) exhibit notable affinity for 5-HT7R (Ki = 9.08 and 0.85 nM, respectively) and selectivity over the 5-HT1AR (254- and 48-fold, respectively). The structure-affinity relationships for these three new classes of 5-HT7R ligands are discussed and, in order to rationalize and deeply investigate the observed results, molecular modeling studies were performed
本文介绍了三个(苯并)噻吩并嘧啶酮新系列(AC)的5-羟色胺5-HT7和5-HT1A受体的合成及其结合特性。所有系列在杂环支架的2位上都显示一个碱性部分,例如A系列的N,N-二烷基氨基烷硫基链和B和C系列的苯基哌嗪,苄基哌嗪或苄基哌啶烷基链。化合物在5时具有最佳结合性能-HT7R属于B和C类型。尤其是,衍生物B2和C1(RSC4)对5-HT7R表现出显着的亲和力(分别为Ki = 9.08和0.85 nM)和对5-HT1AR的选择性(分别为254和48倍)。讨论了这三类新的5-HT7R配体的结构亲和性关系,为了合理化和深入研究观察到的结果,进行了分子建模研究。特别地,通过将合成的化合物对接在通过同源性建模适当建立的两种受体蛋白中来研究它们的结合姿势。计算出的结合能与实验测得的Ki值具有极好的一致性,进一步验证了模型的质量。
