Antitumor agents 200.1 cytotoxicity of naturally occurring resveratrol oligomers and their acetate derivatives
摘要:
Eleven resveratrol oligomers and six acetylated derivatives were evaluated for in vitro cytotoxicity against a panel of human tumor cell lines. The acetate of (-)-ampelopsin A (12) showed potent and selective cytotoxic activity with ED50 values of 0.6, 0.7 and 2.0 mu g/mL against KB, 1A9 and MCF-7 cells, respectively. Hopeaphenol (10) and pallidol hexaacetate (13) also showed significant cytotoxicity against KB cells with ED50 values of 1.2 and 1.6 mu g/mL, respectively. (C) 1999 Elsevier Science Ltd.

Horseradish Peroxidase (HRP) is a commercially available and prevalently used peroxidase with no specific substrate binding domain. However, after being incorporated with different metal cations, new catalytic functions were found in biomimetic oxidation of resveratrol. Based on the results of screening, Ca, Cu, Fe and Mn incorporated enzymes showed distinctive effects, either decomposition or dimerization products were observed.

The simple synthesis of (±)-parthenostilbenins A and B and (±)-quadrangularins A and B, as well as several unnatural resveratrol dimers, was successfully accomplished for the first time. Moreover, (±)-restrytisols B, (±)-leachianols F and G were efficiently prepared with higher yields compared with those in the literatures.
