Research record
Overview
Compound name: AICAR
Alternative names: AICA riboside; 5-Aminoimidazole-4-carboxamide ribonucleotide (intracellular active form)
Compound classification: Small-molecule nucleoside analog; AMPK activator
Brief factual description:
AICAR is a synthetic nucleoside analog that is metabolized intracellularly to ZMP, an AMP analog. It is widely used in research to activate AMP-activated protein kinase (AMPK), a central regulator of cellular energy balance.
Mechanism of Action
Primary biological targets: AMP-activated protein kinase (AMPK)
Affected systems: Metabolic, muscular, cardiovascular, cellular energy regulation
Receptor selectivity: Enzyme signaling modulation rather than receptor binding
Downstream signaling effects:
Activation of AMPK via accumulation of ZMP
Increased glucose uptake and fatty acid oxidation
Inhibition of anabolic, ATP-consuming pathways
