SU 1498 is a selective inhibitor of the receptor tyrosine kinase VEGF receptor 2 (VEGFR2, aka FLK1; IC50 = 700 nM).

Flk-1 (IC50 = 700 nM)

| ln Vitro |
SU1498 encourages the build-up of phosphorylated extracellular kinases (ERKs) in human aortic and umbilical vein endothelial cells. This process is contingent upon the activity of B-Raf, MEK kinases, and the upstream elements of the MAPK pathway. SU1498 is ineffective on its own; the increased accumulation of phospho-ERKs is only seen in cells that have been stimulated with sphingosine 1-phosphate or protein growth factors[2]. In MS1 VEGF cells, SU1498 inhibits VEGFR2 signal transduction.Ets-1 expression levels are reduced in the presence of SU1498, indicating that VEGF-VEGFR-2 interactions supported baseline levels of Ets-1 expression and that disruption of this autocrine interaction with SU1498 resulted in decreased expression of Ets-1[3]. U87 cell apoptosis and proliferation are markedly impacted by SU1498 treatment. Glycerophosphocholine decreases and lipids increase significantly when exposed to SU1498. Consequently, the cytoplasm of U87 cells treated with SU1498 exhibits an accumulation of lipid droplets[4].

| Enzyme Assay |
Pipetted into tubes (1 μL each), the ERK1 or ERK2 solution is combined with 0–10 μL of 50 μM SU1498 (in kinase buffer without ATP). Buffered tube only receives buffer. The mixtures are incubated for 10 minutes at 25°C after the volume is adjusted to 11 μL using the same buffer. After that, 40 μL of the Elk1-ATP-buffer solution is added, and the incubations are kept going for 30 minutes at 30°C. After heating the mixture of 4× sample buffer mix for 10 minutes at 95°C, 20 μL is added to stop the reactions. SDS-PAGE is used to fractionate the samples (15 μL), and anti-phospho-Elk1 antibody is used for immunoblotting to identify phosphorylated Elk1[2].
|
| Cell Assay |
In order to perform the cell proliferation assay, 30,000 U87 cells are seeded in each well of a 24-well plate and left to attach overnight. Next, the cells are treated in triplicate wells for 24 or 72 hours at varying concentrations of either SU1498 (1 µM to 30 µM) or bevacizumab (10 ng/mL to 250 µg/mL). After that, the MTT test is used to evaluate the cell viability[4].

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.40 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2.5 mg/mL (6.40 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
