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.).
Potent, β1-selective, allosteric drug and metabolite (ADaM) site AMP-activated protein kinase (AMPK) activator in cultures and in vivo.
The AMP-activated protein kinase (AMPK) is an alphabetagamma heterotrimer that plays a pivotal role in regulating cellular and whole-body metabolism. Activation of AMPK reverses many of the metabolic defects associated with obesity and type 2 diabetes, and therefore AMPK is
The metabolic stress-sensing enzyme AMP-activated protein kinase (AMPK) is responsible for regulating metabolism in response to energy supply and demand. Drugs that activate AMPK may be useful in the treatment of metabolic diseases including type 2 diabetes. We have determined

AMP-activated protein kinase (AMPK) plays a key role in maintaining energy homeostasis. Activation of AMPK in peripheral tissues has been shown to alleviate the symptoms of metabolic diseases, such as type 2 diabetes, and consequently AMPK is a target for

Here we report that 5'-monophosphate (AMP)-activated protein kinase (AMPK) agonist A-769662 inhibited hydrogen peroxide (H₂O₂)-induced viability loss and apoptosis of human and mouse osteoblast cells. H₂O₂-induced moderate AMPK activation in osteoblast cells, which was enhanced by A-769662. Inactivation of AMPK
AMP-activated protein kinase (AMPK) is a key sensor and regulator of intracellular and whole-body energy metabolism. We have identified a thienopyridone family of AMPK activators. A-769662 directly stimulated partially purified rat liver AMPK (EC50 = 0.8 microM) and inhibited fatty
