i.e. TMECG, synthesis of a trimethoxy derivative of epicatechin-3-gallate, which shows high antiproliferative and proapoptotic activity against melanoma. It is a prodrug that is selectively activated by the specific melanocyte enzyme tyrosinase. Upon activation, the compound generates a stable quinone methide product that strongly inhibits dihydrofolate reductase in an irreversible manner. The treatment of melanoma cells affects cellular folate transport and the gene expression of DHFR
