Bivalent ligands represent useful tools to investigate the phenomenon of GPCR dimerization. We synthesized bivalent ligands based on (R)-apomorphine with variations in spacer length, and assessed these compounds in functional and binding assays at the dopamine D2 receptor. The results present novel SAR for bivalent ligands targeting the D2R, and identify a relationship for spacer length with ligand potency, efficacy and affinity.
双价配体是研究GPCR二聚化现象的有用工具。我们基于(R)-阿朴吗啡合成了不同间隔区长度的双价配体,并在多巴胺D2受体上通过功能性和结合试验评估了这些化合物。结果展示了针对D2R的双价配体的新型结构活性关系,并揭示了间隔区长度与配体效能、效力和亲和力之间的关系。
