生物活性:
Regorafenib (BAY 73-4506) mesylate 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 mesylate shows very robust antitumor and antiangiogenic activity.

体内研究:
Regorafenib mesylate (10 mg/kg, Orally, single dose or daily for 4 days) inhibits tumor vasculature and tumor growth in a rat GS9L glioblastoma model.Regorafenib mesylate (0-100 mg/kg, Orally, qd × 9) exhibits antitumorigenic and antiangiogenic effects in the Colo-205, MDA-MB-231 and 786-O model.Animal Model:Rat GS9L glioblastoma xenograft
Dosage:10 mg/kg
Administration:Orally, single dose or daily for 4 days
Result:Inhibited tumor vasculature and tumor growth in a rat GS9L glioblastoma model.
Animal Model:Female athymic NCr nu/nu mice, Multiple xenograft models, including models derived from CRC (Colo-205), BC (MDA-MB-231) and RCC (786-O) tumors
Dosage:0, 3, 10, 30, 100 mg/kg
Administration:Orally, qd × 9
Result:Effectively inhibited growth of the Colo-205, MDA-MB-231 and 786-O model. Significantly reduces tumor MVA, effectively inhibited the RAF/MEK/ERK signaling cascade, and drastically inhibited tumor cell proliferation.

体外研究:
Regorafenib mesylate (0-10 μM, 96 h) shows anti-proliferation activity in GIST 882, Thyroid TT, MDA-MB-231, HepG2, A375 and SW620 cells.Regorafenib mesylate (0-3000 nM, 30 min) inhibits the autophosphorylation of VEGFR2, TIE2 and PDGFR-β, and inhibits FGFR and pERK1/2.Regorafenib mesylate 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.
