描述 Imatinib Mesylate is the mesylate form of Imatinib. Imatinib is a multiple target inhibitor with IC50 values of 100nM, 100nM, 38nM, 25nM and 25nM for PDGFR, c-kit, v-Abl, c-abl and bcr-abl (measured by in vitro enzyme assays), respectively, usually used for treatment of chronic myelogenous leukemia (CML)[1][2][3]. In cellular study showed that treatment with Imatinib for 90min could selectively inhibited the autophosphorylation of v-AbI at concentration>3μM in PB-3c cI. 15 cells, PDGF-BB-induced autophosphorylation of PDGFR at concentration>0.3μM in BALB/c 313 cells[1], steel factor–dependent phosphorylation of c-kit and steel factor-dependent activation of Akt at concentration>1μM in M-07e cells, as well as autophosphorylation of an activated mutant form of c-kit and c-kit–dependent activation of MAP kinase/AKT at concentration>0.1μM in HMC-1 cells. Consistent with this, Imatinib showed anti- proliferative effect on HMC-1 cells by 90%-95% at concentration ranging in 0.1μM-10μM, which may due to the abrogation by Imatinib of antiapoptotic effect of mutant c-kit activation. [2]. Intraperitoneal injection with Imatinib at dose of 50mg/kg once daily for 30 days suppressed tumor growth in BALB/c AMuLV and BALB/c 3T3 v-sis cells xenograft mice[1].
作用机制 Imatinib can bind with the ATP binding site of BCR/ABL tyrosine kinase, thus keeps BCR/ABL in an inactive form[4].
