Baicalein, an important active constituent of the traditional Chinese herb Scutellaria baicalensis, exhibited antitumor activity and inhibitory activity against P‐gp 170. The syntheses of 25 baicalein derivatives, 2–26 (Table), are described here (Scheme 1). These compounds were systematically modified with O‐alkylation and O‐acylation at HOC(5), HOC(6), and HOC(7), singly or in combination, on
黄ical素是传统中草药黄cut的重要活性成分,具有抗P-gp 170的抗肿瘤活性和抑制活性。这里描述了25种黄ical素衍生物2 – 26的合成(表1)(方案1)。这些化合物进行了系统的修饰ö烷基化和ö酰化在HO C(5),HO C(6),和HO C(7),单独或组合,在环甲为了评价这样的修改对他们的抑制活性对耐多药的肿瘤细胞系和P-gp的作用的黄芩素170在110的高选择性,高效的烷基化全乙酰化的黄芩素C(7)是关键的区别HO C(6)和HO 黄芩素的C(7)。
