Side-by-side comparison of key properties, dosing, and research.

AICAR
Summary
PNC-27 is a synthetic peptide derived from the p53 tumor suppressor protein, containing both an HDM2-binding domain and a transmembrane penetratin sequence. It selectively kills cancer cells by binding MDM2/HDM2 overexpressed on the plasma membrane of malignant cells, inducing membranolysis without harming normal cells.
AICAR is a cell-permeable AMP analog that activates AMPK (AMP-activated protein kinase) — the master metabolic switch that triggers fat burning, mitochondrial biogenesis, and adaptations normally only achieved through exercise. It has been called the 'exercise in a pill' compound.

Key Benefits
  • Selective cytotoxicity against cancer cells overexpressing HDM2/MDM2
  • Spares normal cells lacking surface HDM2 expression
  • Membranolytic mechanism bypasses intracellular resistance pathways
  • Demonstrated activity against breast, pancreatic, leukemia, and melanoma cell lines
  • Potential for combination with conventional chemotherapy
  • Novel non-genotoxic anticancer mechanism
  • AMPK activation mimics aerobic exercise adaptations
  • Increased fat oxidation and endurance
  • Mitochondrial biogenesis (PGC-1alpha)
  • Improved insulin sensitivity and glucose metabolism
  • Anti-inflammatory effects
  • Potential cardiac protection during ischemia
  • Synergistic with actual exercise training
  • Reduces hepatic glucose production
Side Effects
  • Limited human clinical data; largely in vitro and animal studies
  • Potential immunogenic reactions (foreign peptide)
  • Systemic toxicity at high doses not well characterized
  • Unknown interactions with current chemotherapy agents
  • Hypoglycemia risk
  • Lactic acidosis at high doses (animal data)
  • Injection site irritation
