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 15μM.
Objective: To investigate the cytotoxicity of new naphthoquinones derivatives on MCF-7 cells.
Methods: 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.
