<dcterms:abstract xml:lang="fr">Les cancers représentent un problème majeur de santé public d'où la nécessité de rechercher de nouvelles classes de médicaments. Parmi les pistes pour développer de nouveaux traitements, deux ont retenu notre attention et celle de nos collaborateurs : la modulation de l’épissage par des composés comme le NVS-SM2, et l’inhibition de l’oncogène KRAS par des dérivés de produits naturels, les flavaglines. Dans ce contexte, nous avons développé la première synthèse robuste du NVS-SM2, qui peut satisfaire la demande globale de cet agent pour examiner en détail son potentiel thérapeutique dans différents types d’affection. En outre, la stratégie de synthèse rapportée ici pourrait être étendue à de nouveaux analogues de ce composé. D’autre part, nous avons synthétisé de nouvelles flavaglines qui sont en cours d'étude pour leurs effets sur l’inhibition de KRAS. Au cours de cette étude, nous avons découvert de nouvelles réactions, notamment une inversion de configuration d’amines induite par du chlorure de diméthylcarbamoyle.</dcterms:abstract>
