  In vitro and in vivo anticancer activity evaluation of ursolic acid derivatives

  摘要：

  Twenty-three ursolic acid (1) derivatives 2-24 (ten novel compounds 8-10, 14-17 and 22-24) modified at the C-3 and the C-28 positions were synthesized, and their structures were confirmed by IR, (1)H NMR, MS, and elemental analysis. The single crystals of compounds 15 and 17 were obtained. The cytotoxic activity of the derivatives was evaluated against HepG2, BGC-823, SH-SY5Y, HeLa and HELF cells by the MTT assay. The induction of apoptosis and affects on the cell cycle distribution with compound 14 were assessed by fluorescence microscopy, flow cytometry and the activity of caspase-3 in HepG2 cells. Compounds 14-17 had more significant antiproliferative ability against the four cancer cell lines and low cytotoxicity to human embryonic lung fibroblast cells (HELF). Compounds 11, 14-16, 21 and 23 were particularly active against HepG2 cell growth. Compound 14 was selected to investigate cell apoptosis and cell cycle distribution. Flow cytometric analysis and morphologic changes of the cell exhibited that treatment of HepG2 cells with compound 14 led to cell apoptosis accompanied by cell cycle arrest at the S phase in a dose-dependent manner. Furthermore, the activity of the caspase-3 enzyme was increased in the treated cells. In vivo studies using H22 xenografts in Kunming mice were conducted with compound 14 at doses of 50, 100 and 150 mg/kg body weight The results revealed that the medium dosage group (100 mg/kg) showed significant anticancer activity (45.6 +/- 4.3%) compared to the control group.

  摘要：

  合成了F16缀合的五环三萜类化合物，桦木素和桦木酸，熊醛，齐墩果酸和甘草次酸衍生物的第一个代表。三萜核在С-3，С-28或С-30位置与一个或两个靶向线粒体的离域亲脂性阳离子F16连接通过丁烷或三甘醇间隔基。使用人类癌细胞系U937（白血病单核细胞淋巴瘤），K562（慢性髓细胞性白血病）和Jurkat（T淋巴细胞白血病）以及人类非恶性成纤维细胞系来评估产品的细胞毒活性。与亲本桦木酸相比，大多数获得的缀合物显示出显着的抗肿瘤作用增强（约100-200倍），并且相对于健康的成纤维细胞，其对肿瘤细胞系的细胞毒性作用明显更高。在一系列测试化合物中，具有桦木素和桦木酸6、8和11的F16缀合物具有最高的选择性，显示出可接受的选择性指数值（≥10）。
