to design new P2Y2R antagonist scaffolds. One P2Y2R antagonist scaffold retained millimolar affinity for the P2Y2R and upon further functionalization with terminal carboxylic acid groups affinity was improved over 100-fold. This functionalized P2Y2R antagonist scaffold was employed to develop new chemotype P2Y2R fluorescent ligands, that were attainable in a convergent five-step synthesis. One of these
P2Y 2受体 (P2Y 2 R) 是癌症、特发性肺纤维化和动脉粥样硬化等疾病的靶标。然而,没有足够的 P2Y 2 R 拮抗剂可用于验证 P2Y 2 R 功能和未来的药物开发。评价 ( R )-5-(7-氯-2-((2-乙氧基乙基)氨基)-4 H-苯并[5,6]环庚[1,2- d ]噻唑-4-基)-1 -methyl-4-thioxo-3,4-dihydropyrimidin-2(1 H )-one 是先前发表的 AR-C118925 的基于噻唑的类似物,在 P2Y 2 R 同源模型中结合,用于设计新的 P2Y 2 R 拮抗剂脚手架。一种P2Y 2 R拮抗剂支架保留了对P2Y 2 R的毫摩尔亲和力,并且在用末端羧酸基团进一步官能化后,亲和力提高了100倍以上。这种功能化的 P2Y 2 R 拮抗剂支架用于开发新化学型 P2Y 2 R 荧光配体,该配体可通过聚合五步合成获得。其中一种荧光配体表现出对分离细胞膜中
