  Synthesis and cytotoxicity evaluation of oleanolic acid derivatives

  摘要：

  Twelve derivatives of oleanolic acid (1) have been synthesized and evaluated for their inhibitory activities against the growth of prostate PC3, breast MCF-7, lung A549, and gastric BGC-823 cancer cells by MU assays. Within these series of derivatives, compound 17 exhibited the most potent cytotoxicity against PC3 cell line (IC50 = 0.39 mu M) and compound 28 displayed the best activity against A549 cell line (IC50 = 0.22 mu M). SAR analysis indicates that H-donor substitution at C-3 position of oleanolic acid may be advantageous for improvement of cytotoxicity against PC3, A549 and MCF-7 cell lines. (C) 2013 Elsevier Ltd.

  A series of pentacyclic triterpene 3β-ester derivatives were designed, synthesized and evaluated as a new class of cholesteryl ester transfer protein (CETP) inhibitors for the treatment of dyslipidemia. In vitro screening assay showed that 5 out of 30 compounds displayed moderate inhibiting human CETP activity with IC50s less than 10 μM. Among them, compound 20 (IC50 = 2.3 μM) had the most potent biological
