CYP1B1 inhibitory capacity. Among these derivatives, compounds 9e and 9j were identified as the most potent two selective CYP1B1 inhibitors with IC50 values of 0.49 and 0.52 nM, respectively, which were 10-fold more potent than the lead compound ANF. In addition, molecular docking and a reasonable 3D-QSAR (three-dimensional quantitative structure-activity relationship) study were performed to provide a
细胞色素P450 1B1(CYP1B1)被公认为是预防癌症和逆转耐药性的重要靶标。为了获得有效和选择性的CYP1B1抑制剂,合成了一系列41种α-萘黄酮(ANF)衍生物,进行了表征,并评估了其对CYP1B1,CYP1A1和CYP1A2的抑制活性。封闭结构对CYP1B1抑制作用的活性关系研究表明,修饰ANF的C环会降低CYP1B1的抑制能力,而在B环的不同位置引入取代基会产生类似的变化CYP1B1的抑制能力。在这些衍生物中,化合物9e和9j被确定为最有效的两种选择性CYP1B1抑制剂,IC50值分别为0.49和0.52 nM,其效力比先导化合物ANF强10倍。此外,进行了分子对接和合理的3D-QSAR(三维定量结构-活性关系)研究,以更好地理解影响CYP1B1抑制活性的关键结构特征。这项研究中获得的结果将为将来开发选择性,有效,低毒和水溶性CYP1B1抑制剂奠定基础。
