Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/18085662

KI20227 is a potent and orally active inhibitor of c-Fms tyrosine kinase (M-CSFR, CSF1R) (IC50 values are 2, 12, 217 and 451 nM for c-Fms, VEGFR-2, PDGFRβ and c-Kit respectively). Ki20227 suppresses osteoclast differentiation and osteolytic bone destruction in a bone metastasis model. Ki20227 inhibits disease progression in a collagen-induced arthritis mouse model. Ki20227 suppresses experimental autoimmune encephalomyelitis. Ki20227 may be a useful therapeutic agent for osteolytic disease associated with bone metastasis and other bone diseases. Ki20227 and its derivatives may also be candidate drugs for the treatment of human multiple sclerosis. Ki20227 is currently in the preclinical developlent stage.
