2,4-dichloro-N-(4-(N-phenylsulfamoyl)phenyl)benzamide (I, pEC50 6.34, Emax 100%). Here, we describe the synthesis and structure-activity relationships of a series of new derivatives and analogs of I. All products were evaluated for their ability to activate GPR27 in an arrestin recruitment assay. As a result, agonists were identified with a broad range of efficacies including partial and full agonists
GPR27 与 GPR85 和 GPR173 一起属于三个受体的小亚家族,称为“大脑中表达的超保守受体”(SREB)。它被假定参与关键的生理过程,如神经元可塑性、能量代谢和胰腺 β 细胞胰岛素分泌和调节。最近,我们报道了第一个选择性 GPR27 激动剂,2,4-二氯-N- (4-( N-苯基氨磺酰基)苯基)苯甲酰胺 ( I , pEC 50 6.34, E max 100%)。在这里,我们描述了I的一系列新衍生物和类似物的合成和构效关系。. 在抑制蛋白募集测定中评估了所有产品激活 GPR27 的能力。结果,确定了具有广泛功效的激动剂,包括部分激动剂和完全激动剂,显示出比先导化合物I更高的功效。最有效的激动剂是 4-chloro-2,5-difluoro- N- (4-( N - phenylsulfamoyl)phenyl)benzamide ( 7y , pEC 50 6.85, E max
