PS10
Based on 6 publication(s) in Google Scholar
PS10 is a novel, potent and ATP-competitive pan-PDK inhibitor, inhibits all PDK isoforms with IC50 of 0.8 μM, 0.76 μM, 2.1 μM and 21.3 μM for PDK2, PDK4, PDK1, and PDK3, respectively. PS10 shows high affinity for PDK2 (Kd= 239 nM) than for Hsp90 (Kd= 47 μM). PS10 improves glucose tolerance, stimulates myocardial carbohydrate oxidation in diet-induced obesity. PS10 has the potential for the investigation of diabetic cardiomyopathy.PDK: pyruvate dehydrogenase kinase

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: ≥ 6.25 mg/mL (19.33 mM); Clear solution
