Application of sunitinib in cancer treatment and analysis of its synthetic route

Abstract

Sunitinib, also known as the free base of sunitinib malate, is an innovative oral agent used in the treatment of tumors. It functions by inhibiting various members of the receptor tyrosine kinase (RTK) family, which possess a split kinase structural domain. These members include vascular endothelial growth factor receptors (VEGFR) 1, 2, and 3, platelet-derived growth factor receptors (PDGFR) and , stem cell factor receptors, FMS-like tyrosine kinase 3, colony-stimulating factor 1 receptor, and BCR/ABL fusion genes. This paper briefly introduces the research background, pharmacological activity and toxicity of sunitinib, sorting out the incidence and pathogenesis of the diseases it is targeted to treat, and its regulatory mechanism in treating the diseases, etc., summarising several synthetic routes of sunitinib researched by the previous researchers, and at the same time analysing and evaluating the synthetic routes and suggesting the synthetic routes, summing up and proposing the outlook of its subsequent research contents and directions, providing references and help to the research on sunitinib afterward.
