Multifaceted roles of vascular endothelial growth factor (VEGF)-neuropilin-1 (NRP1) interaction have been implicated in cancer, but reports on small-molecule inhibitors 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 binding model was obtained. We found that the “aromatic box” enclosed by Tyr297, Trp301 and Tyr353 of NRP1 is critical for NRP1-1 binding. Further structure modification of 1 based on the binding model derived from MD simulations resulted in the identification of 12a with significantly improved activity.

An efficient one-pot synthesis of 2-amino-1,3,4-thiadiazoles from easily available aldehydes and thiosemicarbazide using TBHP as an oxidant has been described. Notably, these reactions were carried out at room temperature using ethanol as solvent. This is the first example for one-pot synthesis of 2-amino-1,3,4-thiadiazole derivatives from aldehydes. This new synthetic methodology provides a simple procedure utilizing a safer oxidizing system that affords the target products in mild reaction condition with satisfactory yields and wide substrate scope.
