Carnosine
Summary
SLU-PP-332 is a small molecule exercise mimetic that activates estrogen-related receptors ERRalpha and ERRdelta (ERRa/d), transcription factors that drive oxidative metabolism programs. In animal studies it significantly enhanced endurance capacity and metabolic fitness without exercise, mimicking many of the cardiovascular and metabolic adaptations of aerobic training.
Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
Half-Life
Not established in humans; rodent pharmacokinetics suggest hours
~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
Admin Route
Oral (research), Subcutaneous (research)
Oral, Topical
Research
Typical Dose
Not established for humans; rodent studies used ~100 mg/kg/day
1,000–2,000 mg
Frequency
Once daily in rodent studies
Once to twice daily with meals
Key Benefits
  • Significant enhancement of aerobic endurance capacity
  • Increases mitochondrial density and oxidative metabolism in muscle
  • Promotes beneficial shift toward oxidative muscle fiber phenotype
  • Improves cardiac efficiency and cardiovascular fitness markers
  • Potential for obesity, metabolic syndrome, and heart failure treatment
  • Exercise mimetic for populations unable to exercise (disability, frailty, disease)
  • Potent anti-glycation (prevents protein cross-linking/aging)
  • Broad-spectrum antioxidant in muscle and brain
  • Extends cell lifespan and protects telomeres
  • Improves muscle performance and delays fatigue (pH buffering)
  • Neuroprotective against Alzheimer's amyloid-beta
  • Wound healing acceleration
  • Anti-cataract properties (eye health)
  • Improves diabetes complications via AGE prevention
  • Chelates excess copper and zinc
Side Effects
  • Limited human data; all studies are preclinical (rodent)
  • Unknown cardiovascular effects with long-term or high-dose use in humans
  • Potential hormonal interactions via ERR pathway (ERRs modulate estrogen-related signaling)
  • Off-target effects not fully characterized
  • Very well tolerated
  • Rare: mild GI discomfort at high doses
  • No significant adverse effects in human studies
