A cell-permeable 4-hydroxy-2-oxo quinoline carboxamide that acts as an agonist of AMPK signaling. It is shown to reduce fat storage in C. elegans (EC50 ~0.1uM) and reduce the expression level of fat-7 (a C. elegans ortholog of mammalian stearoyl-CoA desaturase-1), through aak-1 (an ortholog for the AMPK-a1 catalytic subunit) and K08F8.2 (a transcription factor) dependent mechanisms. In addition, it markedly reduces the number of lipid droplets in HepG2 human hepatocarcinoma cells at 25uM, and elicits the phosphorylation and inactivation of acetyl coenzyme A carboxylase (ACC, the enzyme that catalyzes the rate-limiting step in de novo fatty acid synthesis). F17-induced ACC phosphorylation can be abrogated by simultaneous treatment with an AMPK inhibitor compound C.
Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
