A strain of yeast rendered repair deficient by the conditional expression of the RAD52 locus was used to search for natural products capable of damaging DNA. Four ellagic acid derivatives, namely 3,3′-dimethyl-4′-O-β-D-glucopyranosyl ellagic acid (1), 3,3′,4-trimethyl-4′-O-β-D-glucopyranosyl ellagic acid (2), 3′-methyl-3,4-O,O-methylidene ellagic acid (3) and 3′-methyl-3,4-O,O-methylidene-4′-O-β-D-glucopyranosyl ellagic acid (4), were identified by this assay as DNA damaging natural principles from several plants, including Alangium javanicum, Anisophyllea apetala, Crypteronia paniculata, Mouririi sp. and Scholtzia parviflora. Although none of the isolated principles mediated frank strand scission of DNA in vitro, all of them potently inhibited the growth of yeast in the absence of expression of RAD52.
