Abstract:

We synthesized derivatives with a selective reduction of the carboxyl group and the isolated carbonyl group for the first time, along with derivatives with an isomerized 27, 28 carbon-carbon double bond and several reductively aminated compounds, which have different acid-base properties than gambogic acid. The structures and absolute configurations of all the compounds were determined by means of NMR and IR spectroscopy and HRMS. In in vitro cell proliferation assays against three human cancer cell lines(HL-60, BEL-7402 and A-549), all the tested compounds showed similar inhibitory activity as that of gambogic acid, with low cytotoxicity to normal cells. This work may facilitate the development of structurally modified derivatives as potential anticancer drugs.

Key words: Gambogic acid, Aminated derivatives, Regioselective reduction, Antitumor activities, Cytotoxicity
