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 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
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
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

AMP-activated protein kinase (AMPK) is a crucial metabolic regulator with profound modulatory activities on inflammation. Although the anti-inflammatory benefits of AMPK activators were well documented in experimental studies, the pathological significance of endogenous AMPK in inflammatory disorders largely remains unknown.
