Kit-IN-1
Kit-IN-1 is a kinome-selective and orally active KIT inhibitor with a human IC50 value of 2.8 nM. Kit-IN-1 binds to KIT in an allosteric mode, stabilizes the inactive DFG-out conformation of KIT, and blocks the stem cell factor (SCF)-mediated KIT phosphorylation signaling pathway. Kit-IN-1 inhibits SCF-induced ear swelling in rats and prevents increased vascular permeability. Kit-IN-1 can be used in studies related to mast cell-driven chronic inflammation.

Biological Activity
Kit-IN-1 (compound 7) (0.70 μM; 1-120 min) potently inhibits purified KIT kinase, with an IC50 of 2.8 nM in HTRF assays and 0.89 nM in radiometric assays, and exhibits over 350-fold selectivity over ABL2 kinase[1].
Kit-IN-1 inhibits SCF-induced KIT phosphorylation in M07e cells with an IC50 of 0.16 μM[1].
Kit-IN-1 exhibits excellent selectivity against structurally related kinases, with over 1200-fold selectivity over all type III RTKs (PDGFRα, PDGFRβ, CSF1R, FLT3) and over 610-fold selectivity over DDR1/DDR2; at a concentration of 0.70 μM, its kinome selectivity score S50% is 0.003[1].
Kit-IN-1 exhibits favorable permeability in MDCK-II cells, with moderate efflux mediated by P-gp and BCRP transporters; it also shows good metabolic stability in human and rat hepatocytes[1].
