Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	VEGFR2 ^[1] (Cell-free assay) 6.5 nM VEGFR3 ^[1] (Cell-free assay) 15 nM EphB2 ^[1] (Cell-free assay) 24 nM VEGFR1 ^[1] (Cell-free assay) 30 nM PDGFRα ^[1] (Cell-free assay) 40 nM PDGFRβ ^[1] (Cell-free assay) 49 nM c-Kit ^[1] (Cell-free assay) 78 nM Tie-2 ^[1] (Cell-free assay) 78 nM EphB4 ^[1] (Cell-free assay) 480 nM FGFR1 ^[1] (Cell-free assay) 530 nM c-Met ^[1] (Cell-free assay) 550 nM Abl ^[1] (Cell-free assay) 620 nM
In vitro	AV-951 is a novel quinoline-urea derivative. AV-951 blocks VEGF-dependent activation of mitogen-activated protein kinases and proliferation of endothelial cells. ^[1]
Kinase Assay	Kinase Assays
Kinase Assay	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 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. ^[1] 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. ^[2]

Frequently Asked Questions

Question 1:
Would you please provide a little bit more detail regarding how to prepare it for in vivo treatment and the storage condition?

Answer:
For in vivo formula, we recommend to use 2% DMSO+30% PEG 300+ddH2O up to 1mg/mL. Once dissolved in solution, please make small aliquots and store them at -80C up to 6 months without repeated thawing and refreezing.
