Biochem/physiol Actions
Cabozantinib (XL184; BMS‐907351) is an orally active, potent inhibitor against multiple receptor tyrosine kinases, notably VEGFR2/KDR (IC50 = 35 pM), MET (IC50 = 1.3 nM/wt, 3.8 nM/Y1248H, 11.8 nM/D1246N, 14.6 nM/K1262R), KIT, RET, AXL, TIE2, and FLT3 (IC50 = 4.6, 5.2, 7, 14.3, and 11.3 nM, respectively). Cabozantinib inhibits MET-driven proliferation in cancer cultures (IC50 = 9.9 nM/Hs746T, 19 nM/SNU-5) and simultaneously suppressing metastasis, angiogenesis and tumor growth in vivo (3-100 mg/kg via single or daily p.o. to mice with human MDA-MB-231 xenograft, 1-60 mg/kg via single or daily p.o. to rats with C6 rat glioma).
Orally active, potent receptor tyrosine kinase inhibitor against VEGFR2 (KDR), MET, KIT, RET, AXL, TIE2, and FLT3 with anti-tumor efficacy in vivo.
