pubmed:abstractText |
AMP-activated protein kinase (AMPK) is an energy-sensing enzyme that is implicated as a key factor in controlling whole body homeostasis, including fatty acid oxidation and glucose uptake. We report that a synthetic structural isomer of dihydrocapsiate, isodihydrocapsiate (8-methylnonanoic acid 3-hydroxy-4-methoxy benzyl ester) improves type 2 diabetes by activating AMPK through the LKB1 pathway. In L6 myotube cells, phosphorylation of AMPK and acetyl-CoA carboxylase (ACC) and glucose uptake were significantly increased, whereas these effects were attenuated by an AMPK inhibitor, compound C. In addition, increased phosphorylation of AMPK and ACC by isodihydrocapsiate was significantly reduced by radicicol, an LKB1 destabilizer, suggesting that increased glucose uptake in L6 cells with isodihydrocapsiate treatment is predominantly accomplished by a LKB1-mediated AMPK activation pathway. Oral administration of isodihydrocapsiate to diabetic (db/db) mice reduced blood glucose levels by 40% after a 4-week treatment period. Our results support the development of isodihydrocapsiate as a potential therapeutic agent to target AMPK in type 2 diabetes.
