Une angiogenèse exacerbée est une des caractéristiques (« hallmarks ») du cancer, définies par Hanahan et Weinberg1. Cependant, le ciblage de la voie de signalisation du VEGF (vascular endothelial growth factor) ou de ses récepteurs a montré ses limites thérapeutiques. Après un bénéfice thérapeutique indéniable pour les patients, les tumeurs...

DNA inevitably undergoes a high number of damages throughout the cell cycle. To preserve the integrity of the genome, cells have developed a complex enzymatic machinery aimed at sensing and repairing DNA lesions, pausing the cell cycle to provide more time to repair, or induce apoptosis if damages are too severe. This so-called DNA-damage...

In cancers, hypoxia inducible factor 1 (HIF-1) is an over-expressed transcription factor, which regulates a large set of genes involved in tumour vascularization, metastases, and cancer stem cells (CSCs) formation and self-renewal. This protein has been identified as a relevant target in oncology and several HIF-1 modulators are now marketed or...

Analogs of glutamic acid were synthesized through the asymmetric Michael reaction using chiral acyclicβ-enaminoesters and various Michael acceptors. The influence of the alkoxy group of the enaminoesters andalso the nature of the olefins in the presence or not of zinc chloride on yield and enantioselectivity areexplored.

This review describes the formation of six-membered heterocyclic compounds and their fused analogues under microwave activation using modern organic transformations including cyclocondensation, cycloaddition, multicomponents and other modular reactions. The review is divided according to the main heterocycle types in order of increasing...

This review describes the recent advances in the microwave-assisted synthesis of 7-membered and larger heterocyclic compounds. Several types of reaction for the cyclization step are discussed: Ring Closing Metathesis (RCM), Heck and Sonogashira reactions, Suzuki-Miyaura cross-coupling, dipolar cycloadditions, multi-component reactions (Ugi,...

The therapeutic management of age-related macular degeneration (AMD) is a major public health issue. One of its two late forms, neovascular AMD, is currently treated by intravitreal injections of pharmaceutical active ingredients. Although it is very effective in treating pathologies of the posterior segment of the eye, the intravitreal route...
