Description General description A cell-permeable diarylsulfonamide (DASA) compound that acts as a potent and selective activator of tumor-specific M2 isozyme of pyruvate kinase (PKM2; AC50 = 65 nM). Pretreatment of A549 (adenocarcinomic human alveolar basal epithelial cells) with DASA-10 (~10 µM) prevents hydrogen peroxide, diamide, and hypoxia-induced inactivation of PKM2. DASA treatment is shown to cause a diminution in cellular glutathione levels, and higher oxidative stress-induced cell death. Packaging 10 mg in Glass bottle Packaged under inert gas Warning Toxicity: Standard Handling (A) Reconstitution Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 6 months at -20°C. Other Notes Anastasiou, D., et al. 2011. Science334, 1278. Boxer, M.B., et al. 2010. J. Med. Chem.53, 1048.
