Imatinib mesylate is a small molecule that inhibits the c-Abl protein-tyrosine kinase, a kinase specifically important for proliferation of chronic myelogenous leukemia (CML). A translocation event between chromosomes 9 and 22 generates the Philadelphia chromosome, which then produces the Bcr-Abl fusion protein with aberrant kinase activity that promotes rapid cell proliferation. Imatinib mesylate binds up this crucial kinase, halting CML related growth. Imatinib mesylate has further been displayed to inhibit PDGFR and tyrosine kinases associated with c-Kit. Formulations containing Imatinib mesylate have been used in the treatment of various cancers.

Imatinib mesylate is A tyrosine kinase inhibitor. Highly specific for BCR-ABL, the enzyme associated with chronic myelogenous leukemia (CML) and certain forms of acute lymphoblastic leukemia (ALL).  It’s a potent and selective v-Abl tyrosine kinase inhibitor (IC50 = 38 nM). Also inhibits PDGFR and c-kit. Exhibits selectivity for v-Abl over a panel of other tyrosine and serine/threonine protein kinases. Selectively inhibits PDGF-stimulated growth of v-abl-transformed PB-3 cells and v-sis-transformed BALB/c 3T3 cells in vitro. Exhibits antitumor effects in mice bearing AMuLV or BABL/c 3T3 v-sis cells. Inhibits replication of SARS-CoV and MERS-CoV in vitro (EC50 values are 9.823 and 17.689 μM, respectively).
