factor (VEGF)-neuropilin-1 (NRP1) interaction have been implicated in cancer, but reports on small-moleculeinhibitors of VEGF-NRP1 interaction are scarce. Herein, we describe the identification of 1, a novel nonpeptide small-molecule NRP1 antagonist with moderate activity via structure-based virtual screening. Ensemble docking and molecular dynamics (MD) simulations of 1 were carried out and an interesting
