Resumo
In a search for cancer chemopreventive agents from natural sources, chemical constituents of two kinds of Garcinia plants, Garcinia neglecta and Garcinia puat, collected in New Caledonia, were examined. Five new depsidones, garcinisidone-B (2), -C (3), -D (4), -E (5), and -F (6), were isolated, and their structures were determined by spectrometric analyses. Inhibitory effects of these depsidones on EBV-EA activation induced by TPA in Raji cells were also demonstrated.
