摘要
Nineteen ursolic acid analogues were designed, synthesized, and evaluated for their antiproliferative activity against the Hela and MKN45 cell lines. Some compounds containing a piperazine moiety displayed moderate to high levels of antitumor activities against the tested cancer cell lines. The most potent compound shares the IC50 value of 2.1 mu M and 2.6 mu M for the Hela and MKN45 cell lines, respectively. Further mechanism studies and in vivo antitumor studies have shown that it decreased the apoptosis regulator (BCL2/BAX) ratio, disrupted mitochondrial potential and induced apoptosis, and suppressed the growth of Hela xenografts in nude mice.
