AICAR
AICAR (CAS 2627-69-2)is a cell-permeable, allosteric activator of AMP-activated protein kinase (AMPK). AMPK is a heterodimeric protein serine/threonine kinase that regulates the energy status of cells to protect cell from metabolic stress. AMPK phosphorylates various metabolic enzymes to activate catabolic pathways (e.g. ketogenesis) and block anabolic pathways (e.g. protein synthesis).AICAR demonstrates extensive research value in energy metabolism regulation, the treatment of metabolic diseases, and cellular stress protection by activating the core pathway AMPK.
