product name Brivanib Alaninate
Description: Brivanib is a potent and ATP-competitive inhibitor against VEGFR2 with IC50 of 25 nM, moderate potency against VEGFR-1 and FGFR-1, but >240-fold against PDGFR-β. Brivanib is the hydrolyzed form of Brivanib alaninate, which is a vascular endothelial growth factor receptor 2 (VEGFR2) inhibitor with potential antineoplastic activity. Brivanib strongly binds to and inhibits VEGFR2, a tyrosine kinase receptor expressed almost exclusively on vascular endothelial cells; inhibition of VEGFR2 may result in inhibition of tumor angiogenesis, inhibition of tumor cell growth, and tumor regression.

In vitro activity: BMS-582664 inhibits VEGF-stimulated and FGF-stimulated proliferating of HUVECs with IC50 of 40 nM and 276 nM. BMS-582664 (2 μM) significantly inhibits VEGFR2, FGFR1, ERK1/2 and Akt phosphorylation in VEGF- and bFGF-stimulated SK-HEP1 cells and HepG-2 cells, while BMS-582664 alone has little effect on levels of phosphorylated ERK1/2, Akt, VEGFR2, and FGFR1 in nonstimulated cells. BMS-582664 inhibits CYP2C19, CYP3A4(BFC) and CYP3A4 (BzRes) with IC50 of 2.4 μM, 0.51 μM and 1.6 μM, respectively. BMS-582664 exhibits high solid state stability (only 0.3% degradation at 50℃ with desiccant over a period of 12 weeks) and acceptable solution state stability up to pH 6.5. Kinase Assay: For the VEGFR2, Flk1 and FGFR1 kinase assays, BMS-582664 is dissolved in DMSO and diluted with water/10% DMSO to a final DMSO concentration of 2%. The kinase reactions consists of 8 ng of enzymes with GST tag, 75 μg/mL substrate, 1 μM ATP, and 0.04 μCi [γ-33P]ATP in 50 μL total reaction volume (kinase buffer: 20 mM Tris, pH 7.0, 25 μg/mL BSA, 1.5 mM MnCl2, 0.5 mM dithiothreitol). In all cases, the reactions are incubated for 60 min at 27℃ and terminated with the addition of cold trichloroacetic acid (TCA) to a final concentration of 15%. The percent inhibition from the kinase assays is determined by nonlinear regression analyses, and data are reported as the inhibitory concentration required to achieve 50% inhibition relative to control reactions (IC50). Cell Assay: Cells (HUVECs cell lines) are grown in 100 μL of minimal growth medium and 1.0% heat-inactivated fetal bovine serum in 96-well collagen IV coated plates at a density of 2 × 103 per well in a 37 ℃/5% CO2 environment. Twenty-four hours later, serum is adjusted to 10%, and BMS-582664 at various dilutions are added to each well in a final volume of minimal growth media that contains 10% serum. Forty-eight hours later, 0.5 μCi of [3H]thymidine is added in a volume of 20 μL of minimal media for 24 hours. Plates are washed once in PBS. Upon removal of PBS, Trypsin is added to cells which are subsequently harvested onto glass-fiber filters using an automated harvestor. Incorporated tritium is quantified using a β-counter. Dose−response curves are generated to determine the IC50 value, which is defined as the concentration of drug required to inhibit 50% of tritium incorporation when compared to untreated serum-stimulated cells. |
