- Synthesis and cancer chemopreventive activity of zapotin, a natural product from Casimiroa edulis
-
An efficient method has been developed to synthesize zapotin (5,6,2′,6′-tetramethoxyflavone), a component of the edible fruit Casimiroa edulis, on a multigram scale. The synthesis utilizes a regioselective C-acylation of a dilithium dianion derived from a substituted o-hydroxyactophenone to afford a β-diketone intermediate that can be cyclized to zapotin in good overall yield, thus avoiding the inefficient Baker-Venkataraman rearrangement pathway. Zapotin was found to induce both cell differentiation and apoptosis with cultured human promyelocytic leukemia cells (HL-60 cells). In addition, the compound inhibits 12-O-tetrade-canoylphorbol 13-acetate (TPA)-induced ornithine decarboxylase (ODC) activity with human bladder carcinoma cells (T24 cells), and TPA-induced nuclear factor-kappa B (NF-κB) activity with human hepatocellular liver carcinoma cells (HepG2 cells). These data suggest that zapotin merits further investigation as a potential cancer chemopreventive agent.
