A 769662 Usage And Synthesis

Description

A-769662 is a small molecule thienopyridone that activates AMPK directly in cell-free assays (EC₅₀ = 116 nM) and intact cells by allosterically activating AMPK and inhibiting its dephosphorylation on Thr¹⁷². A-769662 specifically activates β1 subunit-containing AMPK heterotrimers, and its effects are independent of kinases upstream of AMPK. A-769662 has been used to stimulate CYP450-mediated fatty acid oxidation, inhibit adipocyte differentiation, explore glucose uptake in skeletal muscle, and promote endothelial cell survival during metabolic stress.

Uses

A 769662 is an AMP-activated protein kinase (AMPK) activiator. A 769662 selectively activates cardiac AMPK heterotrimeric complexes contg. α2/β1-subunits.

Definition

ChEBI: 4-hydroxy-3-[4-(2-hydroxyphenyl)phenyl]-6-oxo-7H-thieno[2,3-b]pyridine-5-carbonitrile is a member of biphenyls.

Biological Activity

Potent, reversible AMP-activated protein kinase (AMPK) activator (EC 50 = 0.8 μ M) that displays selectivity towards β 1 subunit-containing heterotrimers. Inhibits fatty acid synthesis (IC 50 = 3.2 μ M) and decreases plasma glucose and triglyceride levels in vivo .

storage

+4°C
