A series of 4′‐N‐substituted (aminomethyl)benzoate derivatives of scutellarein were designed and synthesized. Evaluation of their physiochemical properties showed that the designed target compounds 5a–e exhibit higher chemical stability and aqueous solubility than scutellarin and scutellarein. The permeability (P app AP to BL ) of 5c–e in Caco‐2 cells were 2.8, 8.1, and 12.6 times higher than that
设计并合成了一系列黄cut素的4'- N-取代(氨基甲基)苯甲酸酯衍生物。对它们的理化性质的评估表明,所设计的目标化合物5a–e与黄cut苷和黄cut苷相比,具有更高的化学稳定性和水溶性。Caco-2细胞中5c–e的渗透率(P app AP 对 BL)分别比黄素高2.8、8.1和12.6倍,比黄re素高1.3、4.1和6.0倍。特别是5e具有最高的P app AP到BL值(7.19±0.31×10 -6 cm / s)和最低的ER(P app BL to AP / P app AP to BL)值0.17。体外抗氧化评估结果表明5e可以通过减轻线粒体膜电位损失并减少H 2 O 2诱导的活性氧(ROS)的产生来防御H 2 O 2诱导的PC12细胞的氧化损伤。
