摘要：

Twenty oleanolic acid and ursolic acid derivatives were prepared by a modification at C-28 position via introduction with 1,5-pentanedioic acid and glycolic acid followed by amidation with amines, such as morpholine, N-methyl piperazine and N-Boc-ethylenediamine. Their in vitro anticancer activities towards A549, MCF-7 and HepG2 cell lines were evaluated by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide (MTT) method. The results indicated that the anticancer activities of olean-2,12-diene-28-oic acid [1-(2-amino-ethylamino)-1-oxo]ethyl ester (OA-9d), urs-2,12-diene-28-oic acid [1-(2-amino-ethylamino)-1-oxo]ethyl ester (UA-9d) against A549, MCF-7 and HepG2 cells are obviously better than those of lead compounds. The ability of UA-9d to inhibit the expression of hypoxia inducible factor-1 alpha (HCF-1 alpha) in hepatocellular carcinoma Hep3B cells was determined by hypoxia response element (HRE)-dependent molecular assay. The results showed that UA-9d could effectively inhibit the expression of HIF-1 alpha.
