The human P2Y2 receptor ( hP2Y2R) is a G-protein-coupled receptor that shows promise as a therapeutic target for many important conditions, including for antimetastatic cancer and more recently for idiopathic pulmonary fibrosis. As such, there is a need for new hP2Y2R antagonists and molecular probes to study this receptor. Herein, we report the development of a new series of non-nucleotide hP2Y2R
人P2Y2受体(hP2Y2R)是一种G蛋白偶联受体,显示出有望作为许多重要疾病(包括抗转移性癌症以及最近用于特发性肺纤维化)的治疗靶标。因此,需要新的hP2Y2R拮抗剂和分子探针来研究该受体。本文中,我们报告了基于已知的非核苷酸hP2Y2R拮抗剂AR-C118925(1)的新系列非核苷酸hP2Y2R拮抗剂的开发,从而发现了一系列包含不同接头和荧光团的荧光配体。这些缀合物之一98在生物发光能量转移(BRET)分析中显示出对hP2Y2R的微摩尔亲和力(p Kd = 6.32±0.10,n = 17)。用该配体的共聚焦显微镜显示表达未标记hP2Y2R的星形细胞瘤细胞的可置换膜标记。这些特性使98成为研究hP2Y2R分布和组织的首批工具之一。
