Ki20227 is an orally active and highly selective c-Fms tyrosine kinase (CSF1R) inhibitor with IC50s of 2 nM, 12 nM, 451 and 217 nM for CSF1R, VEGFR2 (vascular endothelial growth factor receptor-2), c-Kit (stem cell factor receptor) and PDGFRβ (platelet-derived growth factor receptor β). Ki20227 suppresses osteoclast differentiation and osteolytic bone destruction[1].
Ki20227 (0.1-1000 nM; 72 hours) with 100 and 1,000 nM almost suppresses M-NFS-60 cell growth and HUVEC cell growth, respectively[1].
Ki20227 (0.1-1000 nM; 1 hour) suppresses M-CSF-dependent c-Fms phosphorylation in a dose-dependent manner[1].
Ki20227 (orally;10-50 mg/kg/d for 20 days) of 50 mg/kg/d of Ki20227 for 20 days markedly decreases the osteolytic lesion areas[1].
ki20227 during global ischemia led to a significant deficit in microglial density in the CNS in mice, and CSF1R-inhibition led to a significant reduction in the neuronal density of mice[2].
