This review article explores recent advances in the use of AMPK (AMP-activated protein kinase) activation as a therapeutic approach to anti-inflammation. AMPK, a key sensor of cellular energy status, plays a crucial role in regulating energy homeostasis and glycolipid metabolism. The article highlights the anti-inflammatory effects of various compounds that activate AMPK, including lactones, terpenoids, sesquiterpene lactones, polyphenols, and their derivatives.
**Lactones:**
- **Melatonin:** A natural hormone that regulates sleep-wake cycles and has anti-inflammatory properties. It improves necrotizing enterocolitis (NEC) by increasing antioxidant enzyme activity and reducing oxidative stress.
- **Corosolic Acid (CA):** A pentacyclic triterpene that protects against myocardial hypertrophy through AMPK-dependent autophagy and reduces obesity-associated chronic inflammation.
- **Ilexgenin A (IA):** A pentacyclic triterpene that enhances LKB1-dependent AMPK activity, ameliorates endoplasmic reticulum (ER) stress, and inhibits the NLRP3 inflammasome.
- **Cryptotanshinone (CT):** A quinone diterpene that attenuates ethanol-induced liver injury by inhibiting lipogenesis, oxidative stress, and inflammation through AMPK/SIRT1 and Nrf2 signalling.
**Terpenoids:**
- **Atractylenolide III (AT III):** A sesquiterpene that inhibits pro-inflammatory factors and prevents ulcerative colitis by stimulating the AMPK/SIRT1 signalling pathway.
- **Isovitexin:** A flavone that suppresses pro-inflammatory M1 microglia and enhances anti-inflammatory M2 microglia, providing a strategy for treating inflammation-associated depressive disorders.
- **Nobiletin:** A flavonoid that upregulates autophagy and inhibits the NLRP3 inflammasome, offering potential for enhancing cognitive performance and mental well-being.
- **Luteolin:** A flavonoid that activates the PI3K/Akt/mTOR signalling pathway and protects endothelial cells from oxidative damage via the AMPK pathway.
- **Dihydroricyetin (DHM):** A bioactive polyphenol that counteracts inflammation-induced muscle atrophy through the CaMKK/AMPK pathway.
- **Baicalin:** A flavonoid that inhibits the NLRP3 inflammasome and protects against cerebral ischemia-reperfusion injury by regulating the AMPK/Mfn-2 axis.
- **Mangiferin:** A xanthone that reduces ER stress-related oxidative stress and protects against NAFLD by activating the AMPK/NLRP3 inflammasome pathway.
- **Curcumin:** A compound with excellent anti-inflammatory and antibacterial abilities that inhibitsThis review article explores recent advances in the use of AMPK (AMP-activated protein kinase) activation as a therapeutic approach to anti-inflammation.
