In order to seek promising cancer chemopreventive agents, we assessed the antitumor promoting activities of 3-O-octanoyl- or 3-O-(2-methyloctanoyl)-(--)-epigallocatechins, inhibiting markedly the activation of Epstein-Barr virus early antigen, in a two-stage mouse skin carcinogenesis assay. As a result, these derivatives inhibited a papilloma formation 1.3-1.6-fold more strongly than (--)-epigallocatechin gallate well established as anti-tumor promoter.
