为了提高熊果酸(ursolic acid,UA)的保肝和抗肿瘤活性,设计并合成了8个在UA的C-3、C-11和C-28位进行取代的新型UA衍生物。其结构经IR、MS、1H-NMR和元素分析确证。通过标准MTT测定法评价它们对各种癌细胞系(HeLa、SKOV 3和BGC-823)的体外细胞毒性。其中,化合物13比熊果酸表现出更强的细胞毒性。
In an effort to improve potential hepatoprotective and anti-tumor activities, eight novel ursolic acid (UA) derivatives were designed and synthesized with substitution at positions of C-3, C-11and C-28 of UA. Their structures were confirmed using IR, MS and 1H-NMR and elemental analysis. Their in vitro cytotoxicity against various cancer cell lines (HeLa, SKOV3 and BGC-823) was evaluated by the standard MTT assay. Among them, compound 13 exhibited more potent cytotoxicity than ursolic acid.
