KY-226
Based on 2 publication(s) in Google Scholar
KY-226 is a potent, selective, orally active and allosteric protein tyrosine phosphatase 1B (PTP1B) inhibitor with an IC50 of 0.25 μM, and without PPARγ agonist activity. KY-226 exerts anti-diabetic and anti-obesity effects by enhancing insulin and leptin signaling, respectively. KY-226 also protects neurons from cerebral ischemic injury.

Biological Activity
IC50: 0.25 μM (Protein tyrosine phosphatase 1B (PTP1B))[2]
In human hepatoma-derived cells (HepG2), KY-226 (0.3-10 μM) increases the phosphorylated insulin receptor (pIR) produced by insulin[1].
KY-226 (1 μM; 24 hours; bEnd.3 cells) treatment rescues lipopolysaccharide-induced reduction of mRNA and protein levels of ZO-1. KY-226 treatment restores phosphorylation of pAkt (T308) and its downstream target forkhead box protein O1 (FoxO1) (S256) in bEnd.3 cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:bEnd.3 cells stimulated with LPS
-
Concentration:1 μM
-
Incubation Time:24 hours
-
Result:Rescued lipopolysaccharide-induced reduction of mRNA and protein levels of ZO-1.
KY-226 attenuates plasma glucose elevations in the oral glucose tolerance test. KY-226 also increases pIR and phosphorylated Akt in the liver and femoral muscle[1].

Solvent & Solubility
DMSO : 250 mg/mL (519.03 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.32 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (4.32 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
