We synthesized derivatives of baicalein, wogonin, and chrysin through alkylation at the 7-O-position of the A ring with lipophilic terphenyl or long chain n-alkyl groups, and studied the in vitro anticancer activity of the derivatives through the growth inhibition MTT assay. We discovered that baicalein and two of its derivatives were good free radical scavengers. Among the 20 synthesized derivatives
我们通过在具有亲脂性三联苯或长链正烷基的A环的7- O位上进行烷基化反应,合成了黄ical素,沃戈宁和菊花链素的衍生物,并通过生长抑制MTT分析研究了这些衍生物的体外抗癌活性。我们发现黄ical素及其两个衍生物是良好的自由基清除剂。在20种合成衍生物中,与黄ical苷相比,7- O-法呢基黄ical苷(5d)和7- O-十二烷基黄ical苷(5i)对人结肠癌SW480细胞具有更强的生长抑制作用,最大抑制浓度为一半(IC 50)值分别为1.15和1.57μM。此外,5d和5i剂量和时间依赖性抑制SW480细胞的生长。细胞周期分布分析表明5d和5i通过凋亡机制诱导SW480细胞停滞在S期,这与活性氧的产生增加有关。总之,黄ical素衍生物(5d和5i)的有效抗癌活性表明,这些衍生物是潜在的人类结肠癌抗癌药。
