Axitinib Chemical Properties,Usage,Production
FDA approved axitinib use of treating advanced kidney cancer
January 27, 2012, the FDA approved axitinib for the treatment of advanced kidney cancer (renal cell carcinoma) which other drugs unanswer . Inlyta is manufactured and sold by Pfizer,and is a oral pill taken twice a day.
Renal cell carcinoma is a type of tumor originating from the tubular endothelial cells. Axitinib can prevent certain protein called kinases playing a role in tumor growth and metastasis .
Axitinib is a small molecule tyrosine kinase inhibitor, effective against multiple targets, including VEGF receptors 1, 2 and 3.
Dr. Richard Pazdur, hematology and oncology drugs office director of FDA Drug Evaluation and Research Centre, said: "This is the seven kind of drugs allowed treating metastatic or advanced renal cell carcinoma since 2005 . Overall, during this time ,record level of drug development has dramatically changed the treatment of metastatic renal cell carcinoma paradigm, and offers a variety of treatment options for patients. "
In recent years, the drug has been approved for the treatment of kidney cancer include sorafenib (2005), sunitinib (2006), temsirolimus(2007), everolimus (2009), bevacizumab(2009) and pazopanib(2009).
The above information is edited by the chemicalbook of Tian Ye.
Binding Mode
In the co-crystal structure of axitinib bound to VEGFR2 DFG-out inactive conformation, the indazole scaffold forms two hydrogen bonds with the hinge: one between the indazole NH and the backbone carbonyl of Glu917 and the other between the indazole nitrogen the amide NH backbone of Cys919. The styryl group penetrates through the narrow tunnel and extends toward the solvent front. The phenyl sulfide is positioned slightly higher and deeper into the back pocket as compared to other type II inhibitors. The carboxamide forms one H-bond to the NH backbone of Asp1046 and a second H-bond to the carboxylate side chain of Glu885. The indazole head group substantially complements the full length of the channel, contributing to the high affinity with both polar charge stabilization and hydrophobic interactions. It has also been shown that axitinib binds (in a different conformation from the VEGFR2 binding) to the BCR-ABL fusion protein, specifically inhibiting the drug-resistant T315I mutant isoform.
Description
In January 2012, the US FDA approved axitinib (also referred to as AG-013736) for the treatment of advanced renal cell carcinoma (RCC) for patients who have not responded to prior therapy. Axitinib is a pan VEGF inhibitor and functions by binding to the intracellular tyrosine kinase catalytic domain of VEGF leading to blockade of signaling through this angiogenic pathway. Axitinib is50–400 times more potent for VEGF (enzyme Ki and cellular IC50s for VEGF 1, 2, and 3 are ～0.1 nM) than first-generation inhibitors like sorafenib and sunitinib. Axitinib also inhibits c-Kit and PDGFR(α/β) with enzyme Ki's of ～2 nM and was selective when tested against a broad panel of other protein kinases. Axitinib was discovered by a structure-based drug design approach and binds to the kinase domain of VEGF in a DFG-out conformation. Axitinib blocks VEGF-2 phosphorylation up to 7 h postdose in vivo and inhibits endothelial cell proliferation in xenograft tumors implanted in mice. Synthetic routes to axitinib employing a Migita coupling to form the diaryl sulfide and a Heck reaction to install the 2-styrylpyridine moiety have been reported.
Description
Axitinib is a VEGFR inhibitor (IC50s = 1.2, 0.25, and 0.29 nM for VEGFR1, -2, and -3, respectively). It also inhibits c-Kit and PDGFRβ (IC50s = 1.7 and 1.6 nM, respectively). It inhibits VEGF-induced migration of and tube formation by human umbilical vein endothelial cells (HUVECs). Axitinib (1-100 mg/kg) reduces microvessel density, a marker of angiogenesis, and tumor growth in MV522 colon carcinoma, A375 melanoma, SN12C-GFP renal carcinoma, and U87 glioma mouse xenograft models in a dose-dependent manner. Formulations containing axitinib have been used in the treatment of renal cell carcinoma.

Definition
ChEBI: An indazole substituted at position 3 by a 2-(pyridin-2-yl)vinyl group and at position 6 by a 2-(N-methylaminocarboxy)phenylsulfanyl group. Used for the treatment of advanced renal cell carcinoma after failure of a first line systemic tr atment.
brand name
Inlyta
Biochem/physiol Actions
Axitinib (AG-013736) is an orally available, potent (picomolar) and selective tyrosine kinase inhibitor that blocks VEGF receptors 1, 2 and 3. The drug blocks VEGF-mediated endothelial cell survival, tube formation, and downstream signaling through endothelial nitric oxide synthase, Akt and extracellular signal-regulated kinase.
Clinical Use
Sold under the brand name Inlyta® by Pfizer, Inc., axitinib was approved by the FDA in January 2012 for the treatment of advanced renal cell carcinoma (RCC), specifically after the failure of other systemic treatments. Axitinib slows cancer cell proliferation by inhibition of the vascular endothelial growth factor (VEGF)/VEGF receptor tyrosine (RTK) signaling pathway. In particular, axitinib is a potent inhibitor of VEGF/RTK 1-3, which selectively slows angiogenesis, vascular permeability, and blood flow in solid tumors.
Side effects
The side effects that you should report to your doctor include:
allergic reactions like skin rash, itching or hives, swelling of the face, lips, or tongue;
high blood pressure;
seizures;
signs and symptoms of bleeding such as bloody or black, tarry stools; red or dark-brown urine; spitting up blood or brown material that looks like coffee grounds; red spots on the skin; unusual bruising or bleeding from the eye, gums, or nose;
signs and symptoms of a blood clot such as breathing problems; changes in vision; chest pain; severe, sudden headache; pain, swelling, warmth in the leg; trouble speaking; sudden numbness or weakness of the face, arm, or leg;
stomach pain.
The side effects that usually do not require medical attention include constipation cough, diarrhea, loss of appetite, nausea, and vomiting.
Synthesis
Numerous patents and papers have been disclosed on the synthesis of axitinib, a recently published manuscript details the development of the manufacturing route, and this route is depicted in the scheme. The synthesis began with Migita coupling of commercial iodide 17 with thiophenol 18. Interestingly, this transformation?ˉs efficiency relied upon attention to the number of equivalents of base and an inert atmosphere in the reaction vessel, conditions which minimized catalyst poisoning during the reaction. Without isolation, indazole 19 was iodinated to afford diarylthioether 20 in 85-90% yield over the two steps. Protection of the indazole within 20 as its acetamide preceeded a Heck reaction with 2-vinylpyridine, and then subsequent removal of the indazole protection followed by a series of recrystallizations yielded axitinib (IV) in a combined 62% yield over the final 4 steps.
Drug interactions
Potentially hazardous interactions with other drugs
Antipsychotics: avoid with clozapine (increased risk
of agranulocytosis); avoid with pimozide.
Concomitant use with strong CYP3A4/5 inhibitors:
avoid; however, if concomitant use cannot be avoided
then reduce the dose of axitinib by approximately
half; subsequent doses can be increased or decreased
based on individual safety and tolerability; if
CYP3A4/5 inhibitor is discontinued, then increase
the axitinib dose used prior to initiation of the
strong inhibitor after 3-5 half-lives of the inhibitor
(strong CYP3A4/5 inhibitors include ketoconazole,
itraconazole, clarithromycin, atazanavir, indinavir,
ritonavir, saquinavir, and voriconazole).
Metabolism
Axitinib is metabolised primarily in the liver by CYP3A4/5 and to a lesser extent by CYP1A2, CYP2C19, and UGT1A1. Most of the drug is excreted via the faeces and urine as metabolites.
storage
Store at +4°C
