    A-769662 purchased from MCE. Usage Cited in: Mol Cell. 2017 Oct 19;68(2):336-349.e6.  [Abstract]

    AMPK DKO SV40-immortalized MEFs are electroporated with plasmids encoding Myc-tagged AMPK α1, Myc-tagged AMPK α2 and Myc-tagged AMPK α2 S > A. 48 hr later, MEFs are starved for 3 hr and treated for 2 hr with DMSO or 50 mM A769662 before protein extraction. Western blot analysis shows the A769662-induced ACC phosphorylation in transfected cells.

    Description

    A-769662 is a potent, reversible AMPK activator with EC50 of 0.8 μM.

    IC50 & Target[1]

    AMPK

    0.8 μM (EC50)

    In Vitro

    A-769662 is equally potent in activating the baculovirus expressed α1,β1,γ1 recombinant isoform of AMPK (EC50=0.7 μM). A-769662 and A-592107 activate AMPK purified from multiple tissues and species in a dose-responsive manner with modest variations in observed EC50s. EC50s determined for A-769662 using partially purified AMPK extracts from rat heart, rat muscle, or human embryonic kidney cells (HEKs) are 2.2 μM, 1.9 μM, or 1.1 μM, respectively[1]. A-769662 activates endogenous AMPK in LKB1-expressing (HEK293) and LKB1-deficient (CCL13) cells. A-769662 allosterically activates AMPK complexes containing γ1 harboring a substitution of arginine residue 298 to glycine (R298G). A-769662 inhibits dephosphorylation of Thr-172 in the mutant γ1-containing complexes to a similar degree as seen in the wild-type complexes[2]. A769662 (300 μM) has toxic effects on MEF cells. A769662 reversibly inhibits the proteasomal activity[3].

    In Vivo

    A-769662 (30 mg/kg, i.p.) significantly reduced the respiratory exchange ratio (RER) in the SD rat. There are 33% and 58% reductions of malonyl CoA levels in livers of animals treated with 30 mg/kg A-769662 (0.905 nmol/g) or 500 mg/kg metformin (0.574 nmol/g), respectively. A-769662 (30 mg/kg, b.i.d.) significantly decreases fed plasma glucose (30%-40% reduction), while the lower doses (3 and 10 mg/kg) of A-769662 had no effect on the in diabetic ob/ob mice[1].

    Kinase Assay
    [1]

    To assay glycogen phosphorylase b (GPb) activity, 1.5 μg/mL of rabbit GPb is added to a reaction mix containing 20 mM Na2HPO4 (pH 7.2), 2 mM MgSO4, 1 mM β-NADP (β-nicotinamide adenine dinucleotide phosphate), 1.4 U/mL G-6-PDH (Glucose-6-Phosphate-Dehydrogenase) and 3 U/mL PGM (phosphoglucomutase). AMP or test compounds are added to the assay medium at the specified concentrations followed by the addition of glycogen (final concentration 1 mg/mL) to initiate the reaction. After incubating 10 min at 25°C, GPb activity is assessed by measuring absorbance at 340 nm.

    Animal Administration
    [1]

    After acclimation ob/ob and lean mice are randomized to the various treatment groups by body weight and fed glucose levels (tail snip) at 8 AM. Baseline plasma insulin samples are also taken from a subset of the animals representing each treatment group (n=10 ob/ob and n=10 lean ob/+ littermates). Two separate ob/ob and lean littermate studies are completed: 1) an initial 5 day study, and 2) a 14 day study to examine efficacy and more completely characterize the body weight change observed in the 5 day study. Treatment groups for the 5 day study are as follows: ob/ob vehicle (0.2% hydroxypropyl methylcellulose [HPMC], i.p., b.i.d.), A-592107 (10 or 100 mg/kg, i.p., b.i.d.), A-769662 (3 or 30 mg/kg, i.p., b.i.d.), AICAR (375 mg/kg, s.c., b.i.d.), or metformin (450 mg/kg, p.o., q.d., with vehicle in PM), and lean littermates treated with vehicle (i.p., b.i.d.). Treatment groups for the 14 day ob/ob and lean littermate study are as follows: ob/ob vehicle (0.2% HPMC, i.p., b.i.d.), A-769662 (3, 10, or 30 mg/kg, i.p., b.i.d.), or metformin, and lean littermates treated with vehicle or 30 mg/kg of A-769662 (i.p., b.i.d.).

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
