Kit-IN-2
Kit-IN-2 is an orally active and highly selective KIT inhibitor. Kit-IN-2 stabilizes the inactive (DFG-out) conformation of KIT. Kit-IN-2 inhibits mast cell-mediated inflammatory responses by blocking stem cell factor-induced ear swelling and vascular permeability in rats. Kit-IN-2 exhibits favorable pharmacokinetic properties in rats. Kit-IN-2 can be used for studies related to acute allergy.

Biological Activity
Description
In Vitro
Kit-IN-2 (compound 7) potently inhibits the activity of purified KIT kinase in HTRF assays, with an IC50 of 2.8 nM; it suppresses phosphorylated KIT protein in SCF-induced M07e cells, with an IC50 of 14 nM; under physiologically relevant 100% human serum conditions, its IC50 is 0.16 μM[1].
Kit-IN-2 exhibits excellent kinome selectivity, with a selectivity score S (50%) of 0.003 across 371 wild-type kinases, and shows over 350-fold higher selectivity for KIT than ABL2, its only significant off-target kinase[1].
Kit-IN-2 exhibits low potential for drug-drug interactions, with no significant direct or time-dependent inhibitory effects on major human CYP subtypes[1].
Kit-IN-2 (5 μM) exhibits favorable cell permeability and low efflux mediated by P-gp and BCRP[1].
