Regorafenib (BAY 73-4506) monohydrate is an orally active and potent multi-targeted receptor tyrosine kinase inhibitor, with IC50 values of 13/4.2/46, 22, 7, 1.5 and 2.5 nM for VEGFR1/2/3, PDGFRβ, Kit, RET and Raf-1, respectively. Regorafenib monohydrate shows very robust antitumor and antiangiogenic activity.

体外研究(In Vitro) |
Regorafenib monohydrate (0-10 μM, 96 h) shows anti-proliferation activity in GIST 882, Thyroid TT, MDA-MB-231, HepG2, A375 and SW620 cells.
Regorafenib monohydrate (0-3000 nM, 30 min) inhibits the autophosphorylation of VEGFR2, TIE2 and PDGFR-β, and inhibits FGFR and pERK1/2.
Regorafenib monohydrate causes a concentration-dependent decrease in Hep3B cell growth, with an IC50 of 5 μM. Regorafenib subsequently increases the levels of phospho-c-Jun, a JNK target, but not total c-Jun in Hep3B cells.
Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
