説明
Pazopanib Hydrochloride is the hydrochloride salt of a small molecule inhibitor of multiple protein tyrosine kinases with potential antineoplastic activity. It is an oral second-generation multitarget TKI developed by GSK and approved for marketing by the FDA in 2009 and the EMA in 2010. It targets the VEGFR, platelet-derived growth factor receptor, and c-kit, key proteins responsible for tumor growth and survival. It is used to treat patients with advanced RCC and advanced soft tissue sarcoma who have experienced chemotherapy. Pazopanib Hydrochloride has a role as an antineoplastic agent, a vascular endothelial growth factor receptor antagonist, a tyrosine kinase inhibitor, and an angiogenesis-modulating agent.

臨床応用
Pazopanib is a potent and selective multi-targeted receptor
tyrosine kinase inhibitor of VEGFR-1, VEGFR-2, VEGFR-3,
PDGFR-a/b, and c-kit that blocks tumor growth and inhibits angiogenesis.
It was approved for renal cell carcinoma by the U.S. Food
and Drug Administration in 2009 and is marketed under the trade
name Votrient by the drug’s manufacturer, GlaxoSmithKline.

副作用
Pazopanib is synthesized in five chemical steps
starting from 3-methyl-6-nitroindazole, which is converted to the corresponding
2,3-dimethylindazole analog via N-methylation with trimethyloxonium
tetrafluoroborate. Subsequent reduction of the nitro group to
the amino group using tin chloride followed by condensation with 2,4dichloropyrimidine
yields a chloropyrimidinylaminoindazole intermediate.
The final two steps leading up to pazopanib consist of an N-methylation
reaction using iodomethane and cesium carbonate followed by
condensation with 5-amino-2-methylbenzenesulfonamide.
