NVP-BHG712 (NVP BHG-712; NVP BHG712; BHG-712) is a selective and orally bioavailable EphB4 inhibitor with potential anticancer activity. It has an IC50 of 25 nM for EphB4 and IC50s of 0.40 μM, 1.27 μM, and 1.67 μM for c-Raf, c-Src, and c-Abl, respectively, for other kinases. When profiled against other kinases in biochemical as well as cell-based assays, NVP-BHG712 showed high selectivity for targeting the EphB4 kinase. It inhibits EphB4 kinase activity in the low nanomolar range. Following oral administration, BHG-712 exhibits excellent pharmacokinetic characteristics and effectively inhibits EphB4 autophosphorylation in tissues.
Targets |
EphA2 (IC50 = 3.3 nM); EphB4 (IC50 = 3 nM)

ln Vitro |
NVP-BHG712 treatment also inhibits RTK autophosphorylation in stable transfected A375 melanoma cells with an EC50 of 25 nM for EphB4 and 4.2 μM for VEGFR2, respectively. [1]
|
ln Vivo |
NVP-BHG712 (3 mg/kg, p.o.) significantly reduces VEGF-stimulated tissue formation and vascularization in a model of growth factor-induced angiogenesis by inhibiting EphB4 forward signaling. The potent reversal of VEGF-enhanced tissue formation and vessel growth is another benefit of NVP-BHG712 (10 mg/kg/kg, p.o.). The long-lasting exposure of NVP-BHG712 (3 mg/kg, p.o.) results in a long-lasting inhibition of EphB4 kinase activity in mice, with concentrations of around 10 μM in plasma as well as in lung and liver tissue for up to 8 hours.

|
Enzyme Assay |
NVP-BHG712 is a specific EphB4 inhibitor with an ED50 of 25 nM that distinguishes between EphB4 and VEGFR inhibition; it also exhibits activity against c-Raf, c-Src, and c-Abl with IC50 values of 0.395 μM, 1.266 μM and 1.667 μM, respectively.
|
Cell Assay |
NVP-BHG712 inhibited the autophosphorylation of different EphRs in Hek293 cells after transfection. EphB4 was more inhibited by NVP-BHG712 than EphB2, EphA2, EphB3, and EphA2.
|
Animal Protocol |
VEGF-mediated angiogenesis in vivo is induced in a growth factor implant model in mice.
≤30 mg/kg Administered via p.o. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
