Patent Application
20220153685
The present subject matter relates generally to compounds that prevent the ubiquination and subsequent degradation of AMP-activated protein kinase (AMPK). AMPK, also known as 5′ AMP-activated protein kinase or 5′ adenosine monophosphate-activated protein kinase, is an enzyme that plays a role in cellular energy homeostasis. AMPK functions as a metabolic fuel gauge and master metabolic regulator that is activated in response to environmental stressors to restore cellular energy balance. Upon metabolic stress, AMPK suppresses anabolic and promotes catabolic processes to regain energy homeostasis. In the heart, AMPK coordinates the activation of glucose and fatty acid metabolic pathways to ensure increased production of myocardial ATP when required, such as during cardiac ischemia/reperfusion and hypertrophy, causing an increase in AMPK activity that can be viewed as both protective and maladaptive.
AMPK exists as an obligate heterotrimer, composed of three subunits: catalytic kinase α subunit and two associated regulatory subunits, β and γ (subunits), that together make a functional enzyme. It is expressed in a number of tissues, including the liver, brain, and skeletal muscle. Winder W W, Hardie D G, Am. J. Physiol., 277 (1 Pt 1): E1-10 (1999).
AMPK acts as a metabolic master switch regulating several intracellular systems including the cellular uptake of glucose, the (3-oxidation of fatty acids and the biogenesis of glucose transporter 4 (GLUT4) and mitochondria. Thomson et al., Am. J. Physiol. Endocrinol. Metab., 292(1): E196-202 (2007); Ojuka E O, Proc. Nutr. Soc., 63(2): 275-8 (2004); Durante et al., Am. J. Physiol. Endocrinol. Metab., 283(1): E178-86 (2002); Bergeron et al., Am. J. Physiol., 276 (5 Pt 1): E938-44 (1999); Winder W W, J. Appl. Physiol., 91(3): 1017-28 (2001). A recent paper on mice at Johns Hopkins has shown that when the activity of brain AMPK was pharmacologically inhibited, the mice ate less and lost weight. When AMPK activity was pharmacologically raised the mice ate more and gained weight. Gabriele et al., J. Neurochem., 109 Suppl 1: 17-23 (2009). Research in hibernators has also shown that activation of AMPK induces arousal from hibernation and stimulates food intake. Florant, et al., JEB, 213: 2031-2037 (2010). Research in Britain has shown that the appetite-stimulating hormone ghrelin also affects AMPK levels. Wang et al., FEBS letters, 584:1503-8 (2010). The antidiabetic drug metformin (Glucophage) acts by stimulating AMPK (Zhou et al., J. Clin. Invest., 108 (8): 1167-74 (2001); Musi et al., Diabetes, 51(7):2074-81 (2002)), leading to reduced glucose production in the liver and reduced insulin resistance in the muscle. (Metformin usually causes weight loss and reduced appetite, not weight gain and increased appetite, which is opposite of what might be expected given the Johns Hopkins mouse study results.) Recent research has implicated overproduction of AMPK in the genesis of Alzheimer's disease. Polleux, F., “Scripps Research Institute scientists help unravel central mystery of Alzheimer's disease,” Press Release dated 10 Apr. 2013, from www.eurekalert.org (EurekAlert!). This has raised theoretical concern over the safety of Metformin.
AMPK is the master regulator of metabolic homeostasis by sensing cellular energy status. When intracellular ATP levels decrease during energy stress, AMPK is initially activated through AMP or ADP binding and phosphorylation of a threonine residue (Thr-172) within the activation loop of its kinase domain. It has recently been reported that ubiquitination on AMPKα blocks AMPKα phosphorylation by LKB1. The deubiquitinase USP10 specifically removes ubiquitination on AMPKα to facilitate AMPKα phosphorylation by LKB1. Under energy stress, USP10 activity in turn is enhanced through AMPK-mediated phosphorylation of Ser76 of USP10. Thus, USP10 and AMPK form a key feedforward loop ensuring amplification of AMPK activation in response to fluctuation of cellular energy status. Disruption of this feedforward loop leads to improper AMPK activation and multiple metabolic defects. Deng et al., Mol. Cell, 67:614-624 (2016).
Degradation of AMPK by a cancer-specific ubiquitin ligase has been reported in the literature. Cancer cells can occasionally suppress the growth-restrictive AMPK pathway by mutation of an upstream regulatory kinase. A mechanism to suppress AMPK through its ubiquitination and degradation by the cancer-specific MAGE-A3/6-TRIM28 ubiquitin ligase is described in Pineda et al., Cell, 160(4):715-728 (2015). Pineda et al. report that MAGE-A3/6 are necessary for cancer cell viability and are sufficient to drive tumorigenic properties of non-cancerous cells. Screening for targets of MAGE-A3/6-TRIM28 revealed that it ubiquitinates and degrades AMPKα1.
There is a need in the art for compounds that prevent the ubiquination and subsequent degradation of AMPK. The present subject matter satisfies this need.
