showed more potent PR-antagonistic activity than lead compounds 5 (IC50: 500 nM) and 6 (IC50: 65 nM) in alkaline phosphatase (AP) assay. Compound 9b showed solvent-dependent fluorescence intensity, exhibiting strong fluorescence in the presence of PR LBD only in buffer solution. On the other hand, 10b showed a solvent-dependent shift of the fluorescence maximum wavelength in the presence of PR LBD. These
孕酮通过与孕酮受体(PR)结合而参与多种生理过程,包括雌性生殖。我们已经开发了6-芳基香豆素(例如5和6)作为具有受体结合依赖性荧光的非甾体PR拮抗剂。在这项研究中,我们研究了带有杂环芳族部分的香豆素衍生物的结构活性关系和荧光性质。在这些衍生物中,7C(IC 50:34纳米)和图10b(IC 50:24 nM)的显示更有效的PR拮抗活性比铅化合物5(IC 50:500nM的)和6(IC 50:65 nM)在碱性磷酸酶(AP)分析中。化合物9b显示出溶剂依赖性的荧光强度,仅在缓冲液中在PR LBD存在下显示出强荧光。另一方面,在PR LBD的存在下,10b显示出荧光最大波长的溶剂依赖性移动。这些结果表明6-芳基香豆素将是用于PR拮抗剂和靶向PR的荧光探针的有用支架。
