SS-31 (D-Arg-Dmt-Lys-Phe-NH₂) is a novel, synthetically produced tetrapeptide that targets the inner mitochondrial membrane with remarkable specificity . Developed by researchers at Cornell University and the National Institutes of Health, SS-31 was designed to selectively interact with cardiolipin, a unique phospholipid found exclusively in the inner mitochondrial membrane that is critical for maintaining mitochondrial architecture and function. Buy SS-31 Peptide EU & UK

The amino acid sequence of SS-31 is D-Arg-2′,6′-dimethyltyrosine-Lys-Phe-NH₂, with a molecular weight of approximately 639.8 g/mol . The peptide incorporates a dimethyltyrosine (Dmt) residue that confers antioxidant properties, and the use of D-amino acids enhances stability against proteolytic degradation . This unique structure allows SS-31 to concentrate in mitochondria with a thousand-fold higher accumulation compared to the cytoplasm, enabling it to protect mitochondria from oxidative damage at the site where reactive oxygen species (ROS) are generated. Be s t p syc h e d e l i c t h e r a p y e x p l a i n e d

SS-31 binds with high affinity to cardiolipin, the signature phospholipid of the inner mitochondrial membrane that maintains the structural integrity of the electron transport chain complexes .

The Scientific Foundation of SS-31 Peptide Research

Discovery and Development

SS-31 (Elamipretide) was developed through a rational drug design approach targeting the mitochondrial inner membrane . The peptide belongs to a class of compounds known as Szeto-Schiller (SS) peptides, named after the researchers who pioneered their development . SS-31 is the lead compound in this class, demonstrating the most favorable pharmacological properties .

Mechanism of Action: Cardiolipin Targeting and Mitochondrial Stabilization

SS-31 exerts its effects through a unique mechanism involving selective targeting of cardiolipin, the signature phospholipid of the inner mitochondrial membrane .

Cardiolipin Binding: Cardiolipin is a unique dimeric phospholipid found exclusively in the inner mitochondrial membrane that is essential for maintaining the structural integrity of the electron transport chain . SS-31 binds to cardiolipin with high affinity, protecting it from oxidative damage .

Stabilization of Mitochondrial Architecture: By binding to cardiolipin, SS-31 preserves the organization of mitochondrial cristae and prevents the disassembly of electron transport chain supercomplexes . This stabilization is critical for maintaining efficient oxidative phosphorylation .

Reduction of ROS Production: Oxidized cardiolipin can dissociate from electron transport chain complexes, leading to increased ROS generation and further mitochondrial damage . SS-31 protects cardiolipin from oxidation, thereby reducing ROS production at its source .

Restoration of ATP Synthesis: By preserving electron transport chain integrity, SS-31 restores ATP synthesis capacity in mitochondria that have been compromised by oxidative stress or disease .

Selectivity and Distribution

SS-31 demonstrates remarkable selectivity for mitochondria, with a thousand-fold higher accumulation in mitochondria compared to the cytoplasm . This selectivity is achieved through a combination of electrostatic interactions with the mitochondrial membrane potential and specific binding to cardiolipin .
