Biochem/physiol Actions

A-769662 is a potent, β1 subunit-selective, allosteric drug and metabolite (ADaM) site AMPK activator (α1β1γ1 EC50/Emax = 0.15 μM/1.99 vs. 4.51 μM/2.19 with AMP) that promotes a Thr172 phosphorylation in a β1 carbohydrate binding module (CBM) Ser108 phosphorylation-dependent manner. A769662 synergizes with AMP as well as C2 (AMP mimetic) toward Thr172 dephosphorylated/Ser108 phosphorylated AMPK. A-769662 is widely employed in probing AMPK β1 complexes-mediated cellular signaling in cultures (conc range: 1 μM-1 mM) as well as AMPK-dependent physiological and pathological processes in mice and rats in vivo (dosing range: 1-30 mg/kg i.p.).

Nonalcoholic fatty liver disease is a highly prevalent component of disorders associated with disrupted energy homeostasis. Although dysregulation of the energy sensor AMP-activated protein kinase (AMPK) is viewed as a pathogenic factor in the development of fatty liver its role

Metformin, a hypoglycemic drug used for treatment of type 2 diabetes, regulates inflammatory pathways. By using several models of intestinal inflammation, we examined whether metformin exerts anti-inflammatory effects and investigated the basic mechanism by which metformin blocks pathologic signals.

Metformin is a first-line therapeutic option for the treatment of type 2 diabetes, even though its underlying mechanisms of action are relatively unclear. Metformin lowers blood glucose levels by inhibiting hepatic glucose production (HGP), an effect originally postulated to be

A wide variety of agents activate AMPK, but in many cases the mechanisms remain unclear. We generated isogenic cell lines stably expressing AMPK complexes containing AMP-sensitive (wild-type, WT) or AMP-insensitive (R531G) gamma2 variants. Mitochondrial poisons such as oligomycin and dinitrophenol
