AICAR

Research ChemicalExtensive Research

Also known as: Acadesine · AICA Ribonucleotide · ZMP

An AMPK activator known as an 'exercise mimetic' that triggers the same metabolic pathways as endurance exercise, enhancing fat oxidation and glucose uptake.

Overview

AICAR (5-Aminoimidazole-4-carboxamide ribonucleotide) is an analog of adenosine monophosphate (AMP) that activates AMP-activated protein kinase (AMPK), the master metabolic sensor and regulator of cellular energy homeostasis. AMPK is the same pathway activated during exercise, caloric restriction, and metabolic stress. When AICAR activates AMPK, it triggers a cascade of metabolic effects: increased fatty acid oxidation, enhanced glucose uptake into muscle cells (independent of insulin), mitochondrial biogenesis, and improved endurance capacity. In landmark studies by the Salk Institute, AICAR-treated sedentary mice showed a 44% increase in running endurance without any exercise training, earning it the nickname 'exercise in a pill.' AICAR has been banned by WADA due to its performance-enhancing effects.

Mechanism of Action

Enters cells and is phosphorylated to ZMP, which mimics AMP and allosterically activates AMPK. Activated AMPK phosphorylates ACC (increasing fatty acid oxidation), stimulates GLUT4 translocation (increasing glucose uptake), activates PGC-1alpha (promoting mitochondrial biogenesis), and inhibits mTORC1.
