Abstract

Méthode de préparation en phase solide d'une série combinatoire d'analogues structurels du produit naturel qu'est le balanol (ophiocordine, azépinostatine), cette série étant un inhibiteur de la protéine kinase C (PKC) et de la protéine kinase A (PKA). Cette méthode prévoit la synthèse en phase solide de variants analogues du balanol avec introduction d'une grande diversité moléculaire. Le schéma de synthèse est basé sur une analyse rétrosynthétique de la structure native ayant fait apparaître trois blocs principaux comme modèles appropriés de modification. La fraction dicarboxy-fonctionnelle peut être immobilisée par rapport au support polymère soit comme ester monoallyle ou comme anhydride interne. Les séries obtenues selon ce procédé se révèlent particulièrement appropriées pour une présélection à haut rendement de candidats potentiels pour le traitement de mammifères supérieurs, notamment de l'être humain.
