Imatinib mesylate is a tyrosine kinase inhibitor IC50 value of 100 nM, 100 nM, 600 nM for v-Abl, c-kit, PDGFR, respectively [1].
Tyrosine kinase is an enzyme which is a subclass of protein kinase and plays an important role in transferring a phosphate group from ATP to a protein in cells. It is shown that tyrosine kinase plays a pivotal role in the management of disorders in which activation of c-Abl, PDGFR, or c-Kit signaling. Recently, the role of tyrosine kinases in the modulation of growth factor signaling are received more and more attention and gradually become an especial important target [2].
Imatinib Mesylate is a specific tyrosine kinase (abl, c-kit, and PDGFR) inhibitor and is reported to sensitize cells to radio- or chemo-therapy. When tested with Y-79 and WERI-RB-1 Rb cell lines, imatinib mesylate treatment decreased the cell proliferation and invasion with the concentration of 10 μM [3]. In osteoblast cells, administration of imatinib mesylate decreased osteoclast development via stimulating differentiation, inhibiting proliferation and survival [4].
In dog model with mast cell tumor, administration of imatinib mesylate at a dose of 10 mg/kg daily for 1-9 weeks reduced tumor growth via inhibiting tyrosine kinase [5].
