Synthesis and structure-activity relationship of non-peptidic antagonists of neuropilin-1 receptor

Bioorg Med Chem Lett. 2014 Sep 1;24(17):4254-9. doi: 10.1016/j.bmcl.2014.07.028. Epub 2014 Jul 17.

Abstract

Neuropilins (NRPs) are VEGF-A165 co-receptors over-expressed in tumor cells, and considered as targets in angiogenic-related pathologies. We previously identified compound 1, the first non-peptidic antagonist of the VEGF-A165/NRP binding, which exhibits in vivo anti-angiogenic and anti-tumor activities. We report here the synthesis and biological evaluations of new antagonists structurally-related to compound 1. Among these molecules, 4a, 4c and 4d show cytotoxic effects on HUVEC and MDA-MB-31 cells, and antagonize VEGF-A165/NRP-1 binding. This study confirmed our key structure-activity relationships hypothesis and paved the way to compound 1 'hit to lead' optimization.
