derivatives of CAY10583 coupled to fluorescein resulted in a traceable ligand suitable for different fluorescence-based techniques. An HTRF-based displacement assay (Tag-lite) on stably transfected CHO-K1 cells was developed to characterize binding properties of diverse BLT2 ligands. Highly specific binding to the BLT2 receptor was demonstrated in staining experiments on mouse skin tissue, and specific
白三烯 B4 受体 2 (BLT2) 是由 12( S )-hydroxyheptadeca-5 Z ,8 E ,10 E激活的 G 蛋白偶联受体-三烯酸(12-HHT),已被提议作为糖尿病伤口愈合和胃肠道病变的有希望的治疗靶点。在本研究中,描述了基于合成 BLT2 激动剂 CAY10583 的荧光探针的合理设计。与荧光素偶联的几种 CAY10583 衍生物的合成产生了适用于不同荧光技术的可追踪配体。针对稳定转染的 CHO-K1 细胞开发了一种基于 HTRF 的置换测定法 (Tag-lite),以表征不同 BLT2 配体的结合特性。在小鼠皮肤组织的染色实验中证明了与 BLT2 受体的高度特异性结合,并且 BLT2 诱导的 cAMP 信号传导的特异性调节为受体结合和配体功能提供了进一步的证据。综上所述,
