Abstract

Neuropilin-1/-2 (+33 NRPs), VEGF-A165 co-receptors, are over-expressed during cancer progression. Thus, NRPs targeted drug development is challenged using a multistep in silico/in vitro screening procedure. The first fully non-peptidic VEGF-A165/NRPs protein-protein interaction antagonist (IC50=34μM) without effect on pro-angiogenic kinases has been identified (compound-1). This hit showed breast cancer cells anti-proliferative activity (IC50=0.60μM). Compound-1 treated NOG-xenografted mice significantly exerted tumor growth inhibition, which is correlated with Ki-67low expression and apoptosis. Furthermore, CD31+/CD34+ vessels are reduced in accordance with HUVEC-tube formation inhibition (IC50=0.20μM). Taking together, compound-1 is the first fully organic inhibitor targeting NRPs.
