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).

|Description||Sorafenib is a multikinase inhibitor of Raf-1, B-Raf and VEGFR-2 with IC50 of 6 nM, 22 nM and 90 nM in cell-free assays, respectively.|
Sorafenib inhibits both wild-type and V599E mutant B-Raf activity with IC50 of 22 nM and 38 nM, respectively. Sorafenib 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. Sorafenib weakly inhibits FGFR-1 with IC50 of 580 nM. Sorafenib tosylate is not active against ERK-1, MEK-1, EGFR, HER-2, IGFR-1, c-Met, PKB, PKA, cdk1/cyclinB, PKCα, PKCγ, and pim-1. Sorafenib 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. Sorafenib 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. Sorafenib 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, Sorafenib significantly inhibits the phosphorylation of eIF4E and down-regulates Mcl-1 levels in hepatocellular carcinoma (HCC) cells in a MEK/ERK-independent manner. Sorafenib 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, Sorafenib 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.  Sorafenib treatment 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.  Sorafenib 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 Sorafenib (30-60 mg/kg) with TRAIL (5 mg/kg) show dramatic efficacy in TRAIL-resistant HCT116 bax-/- and HT29 tumor xenografts. |
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, Sorafenib tosylate is added before the enzyme initiation. A 50-fold stock plate is made with Sorafenib tosylate serially diluted 1:3 in a 50% DMSO/50% distilled water solution. Final Sorafenib tosylate concentrations range from 10 μM to 4.56 nM in 1% DMSO.

* 1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
