 Gleevec (imatinib mesylate) is a protein-tyrosine kinase inhibitor that blocks the constitutive abnormal tyrosine kinase, Bcr-Abl tyrosine kinase, that is created by the Philadelphia chromosome abnormality found in CML. In colony formation assays using ex vivo peripheral blood and bone marrow samples, imatinib shows inhibition of bcr-abl positive colonies from CML patients. In vivo, it inhibits tumor growth of bcr-abl transfected murine myeloid cells as well as bcr-abl positive leukemia lines derived from CML patients in blast crisis. Imatinib is also an inhibitor of the receptor tyrosine kinases for platelet-derived growth factor (PDGF) and stem cell factor (SCF), c-kit, and inhibits PDGF- and SCF-mediated cellular events. In vitro, imatinib inhibits proliferation and induces apoptosis in gastrointestinal stromal tumor (GIST) cells, which express an activating c-kit mutation.
