AICAR

🔬What Is AICAR

AICAR (5-Aminoimidazole-4-carboxamide ribonucleotide) is an adenosine monophosphate-activated protein kinase (AMPK) agonist that mimics the metabolic effects of exercise. By activating AMPK, AICAR enhances glucose uptake, fatty acid oxidation, and mitochondrial biogenesis without requiring physical exertion. This compound has demonstrated significant efficacy in preclinical models for improving endurance capacity, insulin sensitivity, and metabolic efficiency.

📊Clinical Studies & Results

AICAR (5-Aminoimidazole-4-carboxamide ribonucleoside) is the most well-characterized pharmacological AMPK activator and exercise mimetic:

• ▪AICAR activated AMPK and increased endurance by 44% in sedentary mice without exercise training (Narkar et al., Cell, 2008; PMID: 18674809)
• ▪Enhanced mitochondrial biogenesis through PGC-1α upregulation, increasing mitochondrial content by 50% in skeletal muscle fibers
• ▪AICAR-based exercise mimetic alleviated aging-induced memory impairment by improving mitochondrial quality control through AMPK activation (Liao et al., Food Sci Hum Wellness, 2024)
• ▪Improved glucose uptake in skeletal muscle independent of insulin signaling, via GLUT4 translocation to the cell membrane
• ▪Promoted fatty acid oxidation in both liver and muscle tissue, shifting cellular metabolism toward lipid utilization
• ▪Demonstrated cardioprotective effects by reducing infarct size and preserving cardiac function in ischemia-reperfusion models

AICAR remains the gold standard pharmacological AMPK activator, with demonstrated exercise-mimetic effects spanning endurance, metabolic regulation, neuroprotection, and cardioprotection in extensive preclinical research.
