[FR] L'invention concerne des composés présentant une létalité spécifique pour les cellules cancéreuses. Plus particulièrement, elle concerne des composés et des compositions létaux à sélectivité RAS. L'invention se rapporte en outre à des méthodes de criblage de ces composés ainsi qu'à des méthodes de traitement d'une pathologie chez un mammifère par administration à ce mammifère d'une dose thérapeutiquement efficace de ces composés ou de ces compositions.
Synthesis, Cytotoxic Activity Evaluation and Quantitative Structure-ActivityAnalysis of Substituted 5,8-Dihydroxy-1,4-naphthoquinones and Their O- and S-Glycoside Derivatives Tested against Neuro-2a Cancer Cells
increase in the cytotoxicactivity of acetylated thioglycosidesof NQs, which was partially retained for their deacetylated derivatives. Thiomethylglycosides of 2-hydroxy-1,4-NQs with OH and MeO groups in quinone core at positions 6 and 7, resprectively formed a nontoxic set of compounds with EC50 > 100 μM. A quantitative structure-activity relationship (QSAR) model of cytotoxicactivity of 22 1,4-NQ derivatives
