Dovitinib (CHIR-258) (TKI258, CHIR258) is a multitargeted RTK inhibitor, mostly for class III (FLT3/c-Kit, IC50: 1/2 nM), also effective to class IV (FGFR1/3) and class V (VEGFR1-4) RTKs (IC50: 8-13 nM), less potent to EGFR, InsR, EphA2, c-Met, IGF-1R, Tie2, and HER2.

Dovitinib lactate (TKI-258 lactate)(TKI258) lactate is a potent inhibitor of fibroblast growth factor receptor 3 (FGFR3) (IC50 :5 nM).

Dovitinib lactate hydrate (TKI258) is the Lactate of Dovitinib, which is a multitargeted RTK inhibitor, mostly for class III (FLT3/c-Kit) with IC50 of 1 nM/2 nM, also potent to class IV (FGFR1/3) and class V (VEGFR1-4) RTKs with IC50 of 8-13 nM, less potent to InsR, EGFR, c-Met, EphA2, Tie2, IGFR1 and HER2. Phase 4.
