SS-31 HA - 50MG

SS-31

SS-31 (elamipretide) is a synthetic mitochondria-targeted tetrapeptide (D-Arg–dimethylTyr–Lys–Phe–NH₂) that localizes to the inner mitochondrial membrane, binding cardiolipin to modulate bioenergetics and redox status.^[1] SS-31 shows potent antioxidant, anti-inflammatory, and cytoprotective effects across preclinical and translational models.

Mechanism of Action

• Interacts with cardiolipin and oxidative-phosphorylation proteins to stabilize mitochondrial structure/function and enhance ATP production.^[1][2][3]
• Reduces mitochondrial ROS, preserves ΔΨ_m, and prevents mtDNA release and apoptosis.^{[4][2][5][6][7]}
• Activates Nrf2 and PGC-1α pathways, upregulating antioxidant enzymes and promoting mitochondrial biogenesis/repair.^[5]

Key Effects & Clinical Implications

• Oxidative stress & inflammation: Lowers oxidative markers, raises SIRT1, and suppresses NF-κB/TNF-α signaling in models of diabetes, cardiovascular, and renal disease.^{[4][8][9][10]}
• Neuroprotection: Reduces microglial activation, inhibits Fis1-mediated fission, and limits neuronal apoptosis/BBB disruption in neuroinflammation and subarachnoid hemorrhage models.^[5][11][3]
• Metabolic & cardiovascular disease: Prevents atherosclerotic plaque development, improves endothelial function, and decreases systemic inflammation/lipid accumulation; improves renal function and reduces proteinuria in diabetic nephropathy with CD36/oxidative-stress pathway downregulation.^[9][8]
• Tissue protection & recovery: Ameliorates burn-induced hepatic injury via mtDNA/STING pathway inhibition; protects nucleus pulposus cells from apoptosis/pyroptosis by maintaining mitochondrial dynamics and inhibiting NLRP3 inflammasome activation.^[6][7]
• Respiratory disease: Suppresses cigarette smoke–induced airway inflammation, reduces pro-inflammatory cytokines, and restores mitochondrial function in bronchial epithelium.^[10]
• Tolerability: Generally well tolerated in preclinical studies with no significant toxicity at therapeutic doses.^[2][9][8]

Summary

SS-31 (10 mg) is a mitochondria-targeted antioxidant peptide that stabilizes mitochondrial structure, reduces ROS, and modulates Nrf2/PGC-1α/SIRT1 signaling. It demonstrates efficacy across metabolic, neurodegenerative, cardiovascular, renal, hepatic, and respiratory models, supporting translational potential for disorders involving mitochondrial dysfunction.^{[4][2][12][5][11][6][9][3][8][10][1][7]}

Storage & Handling (Research Use)

• Lyophilized (dry) peptide: Store sealed at −20 °C (long-term). Short-term storage up to 2–3 weeks at 2–8 °C is acceptable.
• After reconstitution: Store at 2–8 °C and use within 7 days, or aliquot into sterile vials and freeze at −20 °C for up to 3 months.
• Light & moisture: Protect from light; keep container tightly closed to avoid moisture uptake.
• Freeze–thaw: Avoid repeated freeze–thaw cycles (use aliquots).
• Solvent compatibility: Choose sterile solvent compatible with your protocol; filter-sterilize if required by your procedures.
• Labeling: Clearly label aliquots with concentration, solvent, and date of preparation.

Storage guidance is general for research peptides and may be adjusted per your lab SOP.
