We report the discovery of a novel azetidine scaffold for colony stimulating factor-1 receptor (CSF-1R) Type II inhibitors by using a structure-based drug design (SBDD) based on a docking model. The work leads to the representative compound 4a with high CSF-1R inhibitory activity (IC 50 = 9.1 nM). The obtained crystal structure of an azetidine compound with CSF-1R, which matched our predicted docking model, demonstrates that the azetidine compounds bind to the DFG-out conformation of the protein as a Type II inhibitor.
