Biochem/physiol Actions

Imatinib mesylate is a tyrosine kinase inhibitor with antineoplastic activity. Imatinib is a potent inhibitor of the Bcr-Abl kinase encoded by the bcr-abl oncogene as well as receptor tyrosine kinases encoded by c-kit and platelet-derived growth factor receptor (PDGFR) oncogenes. Imatinib mesylate inhibition of Bcr-Abl tyrosine kinase created by the Philadelphia chromosome abnormality found in CML decreases proliferation and enhances apoptosis in leukemias CML and ALL. Inhibition of c-kit tyrosine activity inhibits mast-cell and cellular proliferation in those diseases overexpressing c-kit such as gastrointestinal stromal tumor (GIST).
