against CYP1 enzymes, leading to the identification of fluorine-containing compound 15i as the most potent and selective CYP1B1 inhibitor (IC50 value of 0.07 nM), being 84-fold more potent than that of the template molecule ANF. Alternatively, the amino-substituted derivative 13h not only possessed a potent inhibitory effect on CYP1B1 (IC50 value of 0.98 nM), but also had a substantially increased water
细胞色素P450 1B1(CYP1B1)已被很好地验证为预防癌症和逆转耐药性的诱人靶标。为了继续关注这一领域,本文合成了一组在B环中不同的46个6,7,10-三甲氧基-α-萘黄酮衍生物,并针对CYP1酶进行了筛选,从而鉴定了含氟化合物15i作为最有效和选择性的CYP1B1抑制剂(IC 50值为0.07 nM),比模板分子ANF的效力高84倍。另外,氨基取代的衍生物13h不仅对CYP1B1具有强抑制作用(IC 50值(0.98 nM),但与铅ANF相比,其水溶性大大提高(13h为311μg/ mL,ANF为<5μg/ mL)。目前的研究扩大了CYP1B1抑制剂的结构多样性,化合物13h被认为是有希望的起点,具有进一步研究的巨大潜力。
