齐墩果酸衍生物的合成及抗肿瘤活性研究
摘 要 目的:以齐墩果酸为先导化合物,设计并合成一系列基于MEK激酶靶点的齐墩果酸衍生物。方法:利用计算机辅助药物设计技术,确定能和关键位点结合的活性基团。以齐墩果酸为起始原料,经过C-28位酯化、C-3位引入酰胺基得到目标产物。结果:合成了4个新型齐墩果酸衍生物Ⅰ1~Ⅰ4,其结构经MS、1H-NMR、13C-NMR确证,体外研究显示它们的抗肿瘤活性显著高于母体齐墩果酸,其中Ⅰ4对HepG2细胞显示出较强的抑制活性(IC50值为19.12 μmol/L)。结论:Ⅰ4有成为新型MEK抑制剂的潜力。关键词 齐墩果酸衍生物 合成 抗肿瘤活性 计算机辅助药物设计
