AICAR, aminoimidazole carboxamide ribonucleotide, acts as an agonist to AMP-activated protein kinase; AMP-activated protein kinase, also known as AMPK, is an enzyme with an important role in cellular homeostasis and energy regulation.[1] AMPK acts through a variety of means to ultimately stimulate liver fatty oxidation, ketogenesis, beta-cell modulation of insulin secretion, and other functions within the body. AICAR has been shown to stimulate glucose uptake and reduce apoptosis by reducing reactive oxygen compounds within cells.[2][3]
