comprising the design, synthesis, and pharmacological evaluation of a focused library of 3-substituted 2-arylindoles. In a FRET-based inositol monophosphate (IP1) assay we identified compounds 7, 13e, and 34b as antagonists at the GPRC6A receptor in the low micromolar range and show that 7 and 34b display >9-fold selectivity for the GPRC6A receptor over related GPCRs, making 7 and 34b the most potent and
G蛋白偶联受体(GPCR)代表了在药物治疗中至关重要的生物学目标类别。所述GPRC6A受体是新deorphanized C类GPCR,我们最近报道了基于2-arylindole特权结构支架上的第一变构拮抗剂(例如,1 - 3)。在此,我们介绍了针对2-芳基吲哚拮抗剂3的第一个结构-活性关系研究,包括3-取代的2-芳基吲哚的聚焦文库的设计,合成和药理学评估。在基于FRET的肌醇单磷酸(IP 1)测定法,我们鉴定的化合物7,13E,和34b的作为低微摩尔范围内GPRC6A受体的拮抗剂,表明7和34b对GPRC6A受体的选择性是相关GPCR的> 9倍,这使7和34b成为迄今为止报道的最有效和选择性的GPRC6A受体拮抗剂。
