Biological Activity

Description Sorafenib is a multikinase inhibitor of Raf-1 and B-Raf with IC50 of 6 nM and 22 nM in cell-free assays, respectively. Sorafenib inhibits VEGFR-2, VEGFR-3, PDGFR-β, Flt-3 and c-KIT with IC50 of 90 nM, 20 nM, 57 nM, 59 nM and 68 nM, respectively. Sorafenib induces autophagy and apoptosis and activates ferroptosis with anti-tumor activity.

In vitro Sorafenib inhibits both wild-type and V599E mutant B-Raf activity with IC50 of 22 nM and 38 nM, respectively. This compound also potently inhibits mVEGFR2 (Flk-1), mVEGFR3, mPDGFRβ, Flt3, and c-Kit with IC50 of 15 nM, 20 nM, 57 nM, 58 nM, and 68 nM, respectively. It weakly inhibits FGFR-1 with IC50 of 580 nM. This chemical is not active against ERK-1, MEK-1, EGFR, HER-2, IGFR-1, c-Met, PKB, PKA, cdk1/cyclinB, PKCα, PKCγ, and pim-1. It markedly inhibits VEGFR2 phosphorylation in NIH 3T3 cells with IC50 of 30 nM, and Flt-3 phosphorylation in HEK-293 cells with IC50 of 20 nM. This agent potently blocks MEK 1/2 and ERK 1/2 phosphorylation in most cell lines but not in A549 or H460 cells, while having no effect on inhibition of the PKB pathway. It inhibits the proliferation of HAoSMC and MDA-MB-231 cells with IC50 of 0.28 μM and 2.6 μM, respectively. In addition to inhibition of the RAF/MEK/ERK signaling pathway, this compound significantly inhibits the phosphorylation of eIF4E and down-regulates Mcl-1 levels in hepatocellular carcinoma (HCC) cells in a MEK/ERK-independent manner. It inhibits the proliferation of PLC/PRF/5 and HepG2 cells with IC50 of 6.3 μM and 4.5 μM, respectively, and leads to the significant induction of apoptosis.
In vivo Oral administration of Sorafenib (~60 mg/kg) demonstrates broad spectrum, dose-dependent anti-tumor activity against a variety of human tumor xenograft models including MDA-MB-231, Colo-205, HT-29, DLD-1, NCI-H460, and A549, with no evidence of toxicity. In association with the anti-tumor efficacy, this compound treatment potently inhibits MEK 1/2 phosphorylation and pERK 1/2 levels in HT-29 and MDA-MB-231 xenografts but not in Colo-205 xenografts, and significantly suppresses tumor microvessel area (MVA) and microvessel density (MVD) in MDA MB-231, HT-29 and Colo-205 tumor xenografts. This agent produces dose-dependent growth inhibition of PLC/PRF/5 tumor xenografts in SCID mice with TGIs of 49% and 78% at 10 mg/kg and 30 mg/kg, respectively, consistent with the inhibition of ERK and eIF4E phosphorylation, reduction of the microvessel area, and induction of tumor cell apoptosis. It sensitizes bax-/- cells to TRAIL in a dose-dependent manner, through a mechanism involving down-regulating NF-κB mediated Mcl-1 and cIAP2 expression. Combining this compound (30-60 mg/kg) with TRAIL (5 mg/kg) show dramatic efficacy in TRAIL-resistant HCT116 bax-/- and HT29 tumor xenografts.

Kinase Assay:

[1]
  • Biochemical assays

    Recombinant baculoviruses expressing Raf-1 (residues 305–648) and B-Raf (residues 409–765) are purified as fusion proteins. Full-length human MEK-1 is generated by PCR and purified as a fusion protein from Escherichia coli lysates. Sorafenib tosylate is added to a mixture of Raf-1 (80 ng), or B-Raf (80 ng) with MEK-1 (1 μg) in assay buffer [20 mM Tris (pH 8.2), 100 mM NaCl, 5 mM MgCl2, and 0.15% β-mercaptoethanol] at a final concentration of 1% DMSO. The Raf kinase assay (final volume of 50 μL) is initiated by adding 25 μL of 10 μM γ[33P]ATP (400 Ci/mol) and incubated at 32 °C for 25 minutes. Phosphorylated MEK-1 is harvested by filtration onto a phosphocellulose mat, and 1% phosphoric acid is used to wash away unbound radioactivity. After drying by microwave heating, a β-plate counter is used to quantify filter-bound radioactivity. Human VEGFR2 (KDR) kinase domain is expressed and purified from Sf9 lysates. Time-resolved fluorescence energy transfer assays for VEGFR2 are performed in 96-well opaque plates in the time-resolved fluorescence energy transfer format. Final reaction conditions are as follows: 1 to 10 μM ATP, 25 nM poly GT-biotin, 2 nM Europium-labeled phospho (p)-Tyr antibody (PY20), 10 nM APC, 1 to 7 nM cytoplasmic kinase domain in final concentrations of 1% DMSO, 50 mM HEPES (pH 7.5), 10 mM MgCl2, 0.1 mM EDTA, 0.015% Brij-35, 0.1 mg/mL BSA, and 0.1% β-mercaptoethanol. Reaction volumes are 100 μL and are initiated by addition of enzyme. Plates are read at both 615 and 665 nM on a Perkin-Elmer VictorV Multilabel counter at ~1.5 to 2.0 hours after reaction initiation. Signal is calculated as a ratio: (665 nm/615 nM) × 10,000 for each well. For IC50 generation, this compound is added before the enzyme initiation. A 50-fold stock plate is made with this compound serially diluted 1:3 in a 50% DMSO/50% distilled water solution. Final concentrations of this chemical range from 10 μM to 4.56 nM in 1% DMSO.

Effects of sorafenib or sunitinib on LicA-induced cell death, ER stress responses, PLCc1, Ca2+, and ROS in HepG2 cells. HepG2 cells were pretreated with sorafenib or sunitinib for 1 h, then treated with LicA or TG for 1 h (for P-eIF2a and P-PLCc1) or 24 h (for CHOP, ATF6a(p90), and caspase-4). The cell lysates were subjected to Western blot analyses using antibodies against CHOP, ATF6a(p90), caspase-4(C), P-eIF2a, and b-actin.

Sorafenib and PX-866 interact to suppress tumor growth in vivo. Mice were PO administered vehicle diluent, sorafenib (25 mg/kg), PX-866 (2 mg/kg), or the drug combination QD for 3 days. Animals were monitored daily and tumor volume determined every fifth day. Tumors from animals were isolated at day 15 and fixed, sectioned (10-um), and stained against proliferation (Ki67 staining), phospho-ERK1/2 and phospho-AKT staining, the levels of tumor cell apoptosis/cleaved caspase 3, as well as with H&E and 4′,6-diamidino-2-phenylindole (DAPI).
