Biological Activity

Description SU1498, a powerful inhibitor of KDR (IC50 = 0.7 μM), stimulates accumulation of phosphorylated ERK1/2 in endothelial cells.
KDR [1]
In vitro

SU1498 accentuates accumulation of phosphorylated ERK in endothelial cells and inhibits its kinase activity while having no effect on phosphorylation of Akt. SU1498 does not affect phospho-ERK translocation to nucleus[1].

Protocol (from reference)

Cell Research:


  • Cell lines: HUVECs
  • Concentrations: 10 μM
  • Incubation Time: 15 min
  • Method:

    Cells are inoculated into the wells of 6-well culture plates (3 × 105 cells/well) and grown for 16 h in DMEM-based medium at 37 °C in the atmosphere of 5% CO2. After an overnight starvation (0.5% fetal bovine serum), the medium is removed, and the cells are washed with PBS and overlaid with 0.4 ml of DMEM. From this point on, all incubations are done at 25 °C. The inhibitors (SU1498, 10 μM; AG1433, 10 μM; AG1296, 25 μM; PD153035, 1 μM) are added and followed 15 min later by the growth factors: SPP, 1 μm; VEGF, 100 ng/ml; HGF, 100 ng/ml; bFGF, 10 ng/ml; EGF, 10 ng/ml. Forskolin (10 μm), a gratuitous inducer of adenylyl cyclase, is used as a control because of its known ability to enhance ERK phosphorylation. After a 10-min incubation, the medium is siphoned off, and the cells are lysed with 100 μl of lysis buffer. Samples (10 μl) of each lysate are fractionated by SDS-PAGE, and proteins are transferred to nitrocellulose and probed with anti-phospho-Akt or anti-phospho-ERK1/2 antibody. To show comparable loading, anti-actin antibody is used.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

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.
