Bosutinib, sold under the brand name Bosulif, is a small molecule BCR-ABL and src tyrosine kinase inhibitor used for the treatment of chronic myelogenous leukemia.Шаблон:Medcn
Originally synthesized by Wyeth, it is being developed by Pfizer.Шаблон:Cn
Mechanism
It is an ATP-competitive Bcr-Abl tyrosine-kinase inhibitor with an additional inhibitory effect on Src family kinases (including Src, Lyn and Hck).[1][2] It has also shown activity against the receptors for platelet derived growth factor and vascular endothelial growth factor.[3] Bosutinib inhibited 16 of 18 imatinib-resistant forms of Bcr-Abl expressed in murine myeloid cell lines, but did not inhibit T315I and V299L mutant cells.[1]
Bosutinib is metabolized through CYP3A4.
Medical uses
Bosutinib received US FDA and EU European Medicines Agency approval in September 2012, and March 2013, respectively for the treatment of adults with Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) with resistance, or intolerance to prior therapy.[4][5][6][7]
Contraindications
Bosutinib has two known absolute contraindications, which are: known hypersensitivity to bosutinib and liver impairment.[8][9]
Interactions
Bosutinib is both a substrate and an inhibitor of P-glycoprotein (P-gp) and CYP3A4.[1] Hence P-gp and CYP3A4 inhibitors may increase plasma levels of bosutinib.[1] Likewise CYP3A4 inducers may reduce plasma concentrations of bosutinib.[1] It may also alter the metabolism and uptake (into the GIT by means of its P-gp inhibitory effects) of other drugs that are substrates for P-gp and CYP3A4.[1]
