    Product Description

    AICAR is an activator of AMP-activated protein kinase (AMPK).1 It increases AMPK kinase activity in isolated hepatocytes (EC50 = ~500 μM) and reduces HMG-CoA reductase activity and fatty acid and sterol synthesis in these cells. AICAR (0.5 mM) inhibits insulin-stimulated glucose uptake to 62% of control cells and reduces GLUT4 translocation by 2.5-fold in 3T3-L1 adipocytes.2 In astrocyte-enriched glial cells, AICAR (1 mM) prevents increases in protein levels of inducible nitric oxide synthase (iNOS), COX-2, and manganese superoxide dismutase (MnSOD) induced by LPS and amyloid-β (Aβ) (25-35) and expression of TNF-α, IL-1β, and IL-6 induced by LPS and Aβ42.3 AICAR inhibits autophagy in rat hepatocytes (IC50 = 0.3 mM) and induces apoptosis in rat β cells in a concentration-dependent manner.4,5
