human diseases. In a pilot study, novel muscarinic antagonists were synthesized and used as chemical probes to obtain additional information of the muscarinic pharmacophore. The design of these ligands made use of current orthosteric and allosteric models of drug–receptor interactions together with chemical motifs known to achieve muscarinic receptor selectivity. This approach has led to the discovery
已知毒蕈碱受体起重要的生物学作用,并且是几种人类疾病的药物靶标。在初步研究中,合成了新型毒蕈碱拮抗剂并将其用作化学探针,以获得毒蕈碱药效团的其他信息。这些配体的设计利用了目前的药物-受体相互作用的正构和变构模型以及已知可实现毒蕈碱受体选择性的化学基序。这种方法导致发现了几个非竞争性毒蕈碱配体,这些配体在次级受体位点强烈结合。发现这些化合物是非竞争性拮抗剂,在功能测定中完全消除了卡巴胆碱的活化。这些化合物中的几种在M 1处强烈拮抗对咔巴酚的功能响应和M 4高于其余的受体亚型。
