multiple scaffolds useful to antagonize the cancer‐relevant protein–protein interaction p53/Hdm2 is described. The new method is based on the tightly interwoven interplay of multicomponent reaction chemistry, structural biology, computational chemistry, and high‐content NMR‐based screening.

MDM2 and MDM4 proteins prevent apoptosis of cancer cells by negatively regulating the transcription factor p53. Compounds according to Formula I
are selective antagonists of MDM2 and MDM4 proteins, disrupting the p53/MDM2 and p53/MDM4 complex. These compounds therefore are candidate therapeutics for treating cancer as well as other cell proliferative disease states.

A fragment-based strategy, involving “multicomponent reaction chemistry” (MCR), can identify novel chemotypes that disrupt the p53/MDM2 or p53/MDM4 complex employs. This approach uses high resolution structural information to delineate the region of a first protein or a ligand that is nestled within the binding pocket of a second target protein. The identified region is imported into a database containing MCR scaffolds to generate a virtual library of compounds, which subsequently are docked into the binding pocket of the target protein. Results from docking then are used to select compounds for synthesis and screening. A complementary, NMR-based methodology allows for screening the ability of compounds, selected using MCR, to disrupt the p53/MDM2 or p53/MDM4 complex.

[FR] L'invention concerne une stratégie fondée sur des fragments qui utilise la chimie des réactions multicomposants (MCR) et qui permet d'identifier de nouveaux chimiotypes qui perturbent le complexe p53/MDM2 ou p53/MDM4. Cette approche utilise des informations structurales de haute résolution qui délimitent la région d'une première protéine ou d'un ligand qui est niché dans la poche de liaison d'une seconde protéine cible. La région identifiée est importée dans une base de données qui contient des échafaudages de MCR pour générer une bibliothèque virtuelle de composés qui sont ensuite placés dans la poche de liaison de la protéine cible. Les résultats sont ensuite utilisés pour sélectionner des composés pour la synthèse et le criblage. Un procédé complémentaire fondé sur la RMN permet de cribler la capacité de composés sélectionnés par MCR à perturber le complexe p53/MDM2 ou p53/MDM4.
