G protein‐coupled receptor (GPCR) activation and signaling processes. In this context, muscarinic acetylcholine receptors (mAChRs) are highly relevant due to their exemplary role in the study of allosteric modulation. In this work, we compare and discuss two sets of putatively dualsteric ligands, which were designed to connect carbachol to different types of allosteric ligands. We chose derivatives of TBPB [1‐(1′‐(2‐tolyl)‐1
最近,对变构机制的研究已经使人们对G蛋白偶联受体(GPCR)的激活和信号传导过程有了更深入的了解。在这种情况下,毒蕈碱型乙酰胆碱受体(mAChRs)由于在变构调节研究中具有示范作用,因此具有很高的相关性。在这项工作中,我们比较和讨论了两组推定的双空间配体,这些配体旨在将卡巴胆碱与不同类型的变构体配体连接。我们选择了TBPB [1-(1'-(2-甲苯基)-1,4'-双哌啶-4-基)-1 H-苯并[ d ]咪唑-2-2 (3 H)-one]的导数作为M 1。选择性推定的双向配体,以及苄基喹诺酮羧酸(BQCA)的M 1衍生物正变构调节剂,改变变构和正构构件之间的距离。萤光素酶蛋白质互补测定法表明,必须仔细选择接头长度才能产生激动剂或拮抗剂行为。这些发现可能有助于设计偏向的信号传导和/或不同程度的功效。
