Synthesis and biological evaluation of new naphthoquinones derivatives

Abstract : New substituted 1,4-naphthoquinones have been prepared in good overall yields through the naphthol route. The cytotoxicity of these compounds was tested in vitro on MCF-7 breast tumor cells. The most active compound 14 displayed an IC50 of 15microM. OBJECTIVE: To investigate the cytotoxicity of new naphthoquinones derivatives on MCF-7 cells. METHOD: Synthesis of new naphtoquinones derivatives and in vitro evaluation of their cytotoxicity on MCF-7 cells (rezasurin cell-based assay). RESULTS: Starting from Ethyl 4-hydroxy-6,7-dimethoxy-2-naphthoate, four naphthoquinones were prepared and exhibited substantial cytotoxicity against MCF-7 cells. CONCLUSION: Preliminary studies of the structure-activity relationship have shown the influence of the structural parameters and in particular the nature of the naphthoquinone side chain.
