| Description | Regorafenib monohydrate is a multi-target inhibitor for VEGFR1/2/3, PDGFRβ, Kit, RET and Raf-1 with IC50s of 13/4.2/46, 22, 7, 1.5 and 2.5 nM, respectively.In Vitro:Regorafenib potently inhibits VEGFR2 autophosphorylation in NIH-3T3/VEGFR2 cells with an IC50 of 3 nM. In HAoSMCs, regorafenib inhibits PDGFR-β autophosphorylation after stimulation with PDGF-BB, with an IC50 of 90 nM. Regorafenib inhibits the proliferation of VEGF165-stimulated HUVECs, with an IC50 of 3 nM[1]. Regorafenib causes a concentration-dependent decrease in Hep3B cell growth, having 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[3].In Vivo:Regorafenib effectively inhibits growth of the Colo-205 xenografts in the dose range of 10-100 mg/kg reaching a TGI of 75% at day 14 at the 10 mg/kg dose. In the MDA-MB-231 model, regorafenib is highly efficacious at a dose as low as 3 mg/kg, resulting in a significant TGI of 81%, which increases to 93% at doses of 10 and 30 mg/kg, where tumor stasis is reached[1].

Regorafenib monohydrate is a multitargetedinhibitor of tyrosine kinase with IC50 values of 13nM, 4.2nM, 46nM, 2.5nM, 28nM, 19nM, 202nM, 22nM, 7nM, 1.5nM and 311nM, respectively for VEGFR-1, mVEGFR-2, mVEGFR-3, Raf-1, BRAF WT, BRAFV600E, FGFR-1, PDGFR-β, c-KIT, RETand TIE2 [1].
Regorafenib is a multikinase inhibitor of both intracellular and membrane-bound RTKs. It shows potent inhibition of angiogenic and stromal RTKs like VEGF receptors-1-3, PDGFR-β and FGF receptor-1 with IC50 values ranging from4.2 to 311nM in biochemical assays. It also inhibits oncogenic RTKs, such as RET and c-KIT, with IC50 values ranging from 1.5 to 28nM in cellular assays [1].
Regorafenib is reported to have anti-tumor efficacy to various tumors including breast, pancreas, thyroid, melanoma, GIST, and CRC with a mean IC50 value less than 1μM. These inhibition effects of tumor growth are also found in mouse xenograft models after the treatment of regorafenib at dose ranging from 10 to 100 mg/kg [1].

Comparison of the crystal structures of the potent anticancer and anti-angiogenic agent regorafenib and its monohydrate.[Pubmed:27045179]
Acta Crystallogr C Struct Chem. 2016 Apr;72(Pt 4):291-6.
Regorafenib {systematic name: 4-[4-({[4-chloro-3-(trifluoromethy)phenyl]carbamoyl}amino)-3-fluorophenoxy]-1-met hylpyridine-2-carboxamide}, C21H15ClF4N4O3, is a potent anticancer and anti-angiogenic agent that possesses various activities on the VEGFR, PDGFR, raf and/or flt-3 kinase signaling molecules. The compound has been crystallized as polymorphic form I and as the monohydrate, C21H15ClF4N4O3.H2O. The regorafenib molecule consists of biarylurea and pyridine-2-carboxamide units linked by an ether group. A comparison of both forms shows that they differ in the relative orientation of the biarylurea and pyridine-2-carboxamide units, due to different rotations around the ether group, as measured by the C-O-C bond angles [119.5 (3) degrees in regorafenib and 116.10 (15) degrees in the monohydrate]. Meanwhile, the conformational differences are reflected in different hydrogen-bond networks. Polymorphic form I contains two intermolecular N-H...O hydrogen bonds, which link the regorafenib molecules into an infinite molecular chain along the b axis. In the monohydrate, the presence of the solvent water molecule results in more abundant hydrogen bonds. The water molecules act as donors and acceptors, forming N-H...O and O-H...O hydrogen-bond interactions. Thus, R4(2)(28) ring motifs are formed, which are fused to form continuous spiral ring motifs along the a axis. The (trifluoromethyl)phenyl rings protrude on the outside of these motifs and interdigitate with those of adjacent ring motifs, thereby forming columns populated by halogen atoms.
