On-chip angiogenesis assay. Fluorescence imaging of Tg(fli1a:EGFP) embryos at 64 hpf. Transgenic embryos were arrayed and immobilized at 16 hpf and continuously perfused with E3 media containing vehicle control (dimethyl sulfoxide) or selected small-molecule antiangiogenic drugs (Sunitinib and Tivozanib). Right panel: microscopic visualization of patterns of ISV. White arrows: normal ISV growth; blue arrows: partial ISV growth inhibition; and red arrows; complete ISV growth inhibition.

After serum-starvation for 24 h, the MCF7 cells were co-treated with 10 nM TPA and the indicated doses VEGFR inhibitor, Tivozanib, for 24 h. The levels of fibronectin, p-PKC-α, p-ERK, p-AKT, t-AKT and β-actin protein expression were analyzed by western blotting. The levels of fibronectin mRNA were analyzed by real-time PCR. The results are representative of three independent experiments. The values shown are the means ±SEM. * P < 0.05, ** P < 0.01 vs. control. # P < 0.05, ## P < 0.01 vs. TPA-treated cells. Con: control.

Reversal effect of Tivozanib on the sensitivity of HEK/ABCB1 cells to vincrstine. The figure showes the survival curves of cells at different concentrations of vincristine with or without Tivozanib. Cell viability was determined by MTT Assay. HEK293 is human embryonic kidney cell line while HEK/ABCB1 is ABCB1-transfected cell line. Verapamil was used as a positive control of ABCB1 inhibitor.

Figure 7 shows the effect of Tivozanib on the accumulation of [3H]-mitoxantrone. The accumulation of [3H]-mitoxantrone in empty vector transfected HEK293/pcDNA3.1, ABCG2 vector transfected wild-type ABCG2-482-R2, mutant ABCG2-482-G2 and mutant ABCG2-482-T7 cells was measured by the Accumulation Assays. Columns are the mean of triplicate determinations; bars, SD. *P<0.05, **P<0.01 versus the control group. Fumitremorgin C (FTC) was used as a positive control of ABCG2 inhibitor.

|Description||Tivozanib (AV-951) is a potent and selective VEGFR inhibitor for VEGFR1/2/3 with IC50 of 30 nM/6.5 nM/15 nM, and also inhibits PDGFR and c-Kit, low activity observed against FGFR-1, Flt3, c-Met, EGFR and IGF-1R. Phase 3.|
AV-951 is a novel quinoline-urea derivative. AV-951 blocks VEGF-dependent activation of mitogen-activated protein kinases and proliferation of endothelial cells. 
|In vivo||In vivo studies show that AV-951 also decreases the micro vessel density and suppresses VEGFR2 phosphorylation levels in tumor xenografts, especially at a concentration of 1mg/kg (p.o. administration). AV-951 shows almost complete inhibition of tumor xenografts growth (TGI>85%) in athymic rats.  Another study in rat peritoneal disseminated tumor model shows that AV-951 could prolong the survival of the tumor-bearing rats with the MST of 53.5 days. AV-951 displays antitumor activity against many human tumor xenografts including lung, breast, colon, ovarian, pancreas and prostate cancer. |
Kinase Assays:Cell-free kinase assays are done in quadruplicate with 1 μM ATP to determine the IC50 values of AV-951 against a variety of recombinant receptor and nonreceptor tyrosine kinases including VEGFR1, VEGFR2, VEGFR3, c-Kit, PDGFRβ, Flt-3 and FGFR1.
|In vitro||DMSO||20 mg/mL (43.96 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+ddH2O
For best results, use promptly after mixing.
* 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 (mg) = Concentration (mM) × Volume (mL) × 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.

Frequently Asked Questions
Would you please provide a little bit more detail regarding how to prepare the Tivozanib for in vivo treatment and the storage condition?
For in vivo formula, we recommend to use 2% DMSO+30% PEG 300+ddH2O up to 1mg/mL. Once dissolved it in solution, please make small aliquots and store them at -80C up to 6 months without repeated thawing and refreezing.
