AMPK, adenosine monophosphate-activated protein kinase: Click to Expand ⟱
Source:
Type:
AMPK: guardian of metabolism and mitochondrial homeostasis; Upon changes in the ATP-to-AMP ratio, AMPK is activated. (AMPK) is a key metabolic sensor that is pivotal for the maintenance of cellular energy homeostasis. It is well documented that AMPK possesses a suppressor role in the context of tumor development and progression by modulating the inflammatory and metabolic pathways.

-Activating AMPK can inhibit anabolic processes and the PI3K/Akt/mTOR pathway reducing glycolysis shifting toward Oxidative Phosphorlylation.


AMPK activators:
-metformin or AICAR
-Resveratrol: activate AMPK indirectly
-Berberine
-Quercetin: may stimulate AMPK
-EGCG: thought to activate AMPK
-Curcumin: may activate AMPK

-Ginsenosides: Some ginsenosides have been associated with AMPK activation -Beta-Lapachone: A natural naphthoquinone compound found in the bark of Tabebuia avellanedae (also known as lapacho or taheebo). It has been observed to activate AMPK in certain models.
-Alpha-Lipoic Acid (ALA): associated with AMPK activation
