Background:

Regorafenib (BAY 73-4506) is a novel and orally active multikinase inhibitor of receptor tyrosine kinases VEGFR1, VEGFR2, VEGFR3, PDGFRβ, Kit, RET, Raf-1, B-RAF and B-RAFV600E with IC50 values of 13 nM/4.2 nM/46 nM, 22 nM, 7 nM, 1.5 nM, 2.5 nM, 28 nM and 19 nM [1].

VEGFR1/2/3 are vascular endothelial growth factor receptor plays an important role in the formation of normal and tumor vasculature. platelet-derived growth factor receptor-β (PDGFRβ) is a receptor for the platelet-derived growth factor family. Kit, RET and B-RAF are both receptor tyrosine kinases that encoded by proto-oncogenes [1].

Regorafenib (BAY 73-4506) is a novel and orally active receptor tyrosine kinases inhibitor. In NIH-3T3/VEGFR2 cells, regorafenib potently inhibited VEGFR2 autophosphorylation with IC50 value of 3 nM. Regorafenib also inhibited TIE2 and PDGFR-β autophosphorylation with IC50 values of 31 and 90 nM. Regorafenib potently inhibited KITK642E and RETC634W with IC50 values of
