| 4-[4-[[[[4-Chloro-3-(trifluoromethyl)phenyl]amino]carbonyl]amino]-3-fluorophenoxy]-N-methyl-2-pyridinecarboxamide hydrate Usage And Synthesis |
| Uses | 4-[4-[[4-Chloro-3-(trifluoromethyl)phenyl]carbamoylamino]-3-fluorophenoxy]-N-methylpyridine-2-carboxamide Hydrate can be used as an anti-tumor drug. | | Biological Activity | 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]. | | Clinical Use | Regorafenib was approved by the U.S. Food and Drug Administration (FDA) in September 2012 for
the treatment of metastatic colorectal cancer in patients who have previously undergone
fluoropyrimidine-, oxaliplatin-, and irinotecan-based therapies. The FDA expanded the approved use
of the drug to include patients with advanced gastrointestinal stromal tumors (GIST) that cannot be
surgically removed and no longer respond to imatinib and sunitinib, two other drugs approved for
treatment of GIST. Regorafenib, marketed under the trade name Stivarga®, was discovered and
developed by Bayer Pharmaceuticals and marketed jointly with Onyx Pharmaceuticals. The active
metabolites of the drug inhibit multiple targets within a variety of kinase families including those in the RET, VEGF, FGFR, PTK, and Abl pathways. | | Synthesis | Among several published synthesis, the most likely process scale synthesis will be highlighted
from the two published syntheses, and this is described in the scheme. Commercially available
picolinic acid (148) was heated with thionyl chloride to provide the crude intermediate 4-chloro-2-
pyridyl acid chloride which was subsequently reacted with aqueous methyl amine in toluene to give 4-
chloro-2-methylcarboxamide as its hydrochloride salt 149 in quantitative yield after treatment with
acetyl chloride in toluene and ethanol. The hydrochloride salt was free based with sodium hydroxide
and then immediately reacted with imine 150 (formed upon exposure to 4-amino-3-fluorophenol (153)
in refluxing 3-methyl 2-butanone) in base to provide diaryl ether 151 in 84% yield. Reaction of amine
151 with the commercially available isocyanate 152 ultimately delivered regorafenib hydrate (XXIII) in
83% yield. | | references | [1] crona dj, keisler md, walko cm.regorafenib: a novel multitargeted tyrosine kinase inhibitor for colorectal cancer and gastrointestinal stromal tumors.ann pharmacother. 2013 dec;47(12):1685-96. |
