Imatinib is a 2-phenylaminopyrimidine derivative neoplastic agent that belongs to the class of tyrosine kinase inhibitors. Although imatinib inhibits a number of tyrosine kinases, it is quite selective toward the BCR-ABL fusion protein that is present in various cancers. BCR-ABL pathway controls many downstream pathways that are heavily implicated in neoplastic growth such as the Ras/MapK pathway (cellular proliferation), Src/Pax/Fak/Rac pathway (cellular motility), and PI/PI3K/AKT/BCL-2 pathway (apoptosis pathway). Therefore, the BCR-ABL pathway is an attractive target for cancer treatment. Although normal cells also depend on these pathways for growth, these cells tend to have redundant tyrosine kinases to continually function in spite of ABL inhibition from imatinib. Cancer cells, on the other hand, can have a dependence on BCR-ABL, thus more heavily impacted by imatinib.

Imatinib mesylate is a protein-tyrosine kinase inhibitor that inhibits the BCR-ABL tyrosine kinase, the constitutively active tyrosine kinase created by the Philadelphia chromosome abnormality in CML.Although the function of normal BCR is still unclear, ABL activation is overexpressed in various tumors and is heavily implicated in cancer cells growth and survival. Imatinib inhibits the BCR-ABL protein by binding to the ATP pocket in the active site, thus preventing downstream phosphorylation of target protein. 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 GIST cells, which express an activating c-Kit mutation.
