描述 | The RAS/RAF signaling pathway is an important mediator of tumor cell proliferation and angiogenesis. Sorafenib Tosylate, the tosylate form of Sorafenib, is a multitargeted inhibitor with IC50 values of 6nM, 22nM and 38nM for Raf-1, wt-BRAF and BRAF-V599E mutant, respectively, as well as less potent to mVEGFR2, mVEGFR3, mPDGFRβ, FLT3, c-Kit, VEGFR2 and FGFR1 with IC50 values of 15nM, 20nM, 57nM, 58nM, 68nM, 90nM and 580nM (measured by kinase assays), respectively. Sorafenib inhibited activation of the RAF/MEK/ERK pathway at concentration below 15μM, performing by suppressing p-Erk, in most of cell lines tested (like MDA-MB-231. Mia PaCa 2, HCT 116 and HT-29) independent of which mutation caused aberrant activation of the RAS/RAF pathway. Sorafenib targeted receptor tyrosine kinases and inhibited autophosphorylation of VEGFR-2 and PDGFR-β induced by VEGF165 (30ng/ml) in HUVECs/ NIH 3T3 cells and PDGF BB (10ng/ml) in HAoSMCs, respectively. Oral treatment with Sorafenib, at dose of 7.5-60mg/kg daily for 9 days, illustrated a spectrum of antitumor efficacy in a representative panel of tumor xenograft models in a dose-dependent manner, including MDA-MB-231, Colo-205, HT-29, DLD-1, NCI-H460 and A549. Sorafenib showed significant tumor angiogenesis activity, performing as daily oral administration of 30 or 60 mg/kg Sorafenib produced 50-80% inhibition of microvessel area and microvessel density compared with vehicle group in HT-29 tumors[1]. | ||
