Abstract: Optimization of novel azetidine compounds, which we had found as colony stimulating factor-1 receptor (CSF-1R) Type II inhibitors, provided JTE-952 as a clinical candidate with high cellular activity (IC50 = 20 nM) and good pharmacokinetics profile. JTE-952 was also effective against a mouse collagen-induced model of arthritis (mouse CIA-model). Additionally, the X-ray co-crystal structure of JTE-952 with CSF-1R protein was shown to be a Type II inhibitor, and the kinase panel assay indicated that JTE-952 had high kinase selectivity.
