Cabozantinib S-malate

The s-malate salt form of Cabozantinib is very potent orally available inhibitor of multiple receptor tyrosine kinases (RTK), specifically MET and VEGFR2. It also inhibits KIT, FLT3, Tie-2, RET and AXL. Cabozantinib shows dose-dependent inhibition of tumor growth and tumor regression, associated with disruption of the tumor vasculature, angiogenesis and extensive tumor cell apoptosis.
