SS-31 research in Canada investigates the mitochondria-targeted antioxidant properties of this synthetic tetrapeptide. SS-31 (D-Arg-Dmt-Lys-Phe-NH2, also known as Szeto-Schiller peptide 31 or elamipretide) is a cell-permeable peptide that selectively targets the inner mitochondrial membrane by binding cardiolipin. Canadian mitochondrial biology and cardiovascular researchers study SS-31 for its ability to scavenge reactive oxygen species (ROS) directly at the mitochondria and protect electron transport chain function.
Cardiolipin Binding and Mitochondrial Membrane Research
Cardiolipin is a unique phospholipid found almost exclusively in the inner mitochondrial membrane that is essential for electron transport chain (ETC) function. SS-31 binds cardiolipin with high affinity, which concentrates the peptide at the mitochondrial inner membrane — where most mitochondrial ROS are generated. Canadian researchers study how this targeted binding protects cardiolipin from oxidative damage and preserves ETC Complex I-IV function during stress conditions.
Cardiac and Renal Research Applications
SS-31 has been most extensively studied in cardiac ischemia-reperfusion injury and acute kidney injury models. Canadian cardiovascular researchers study SS-31’s ability to reduce mitochondrial ROS production, preserve cardiomyocyte membrane potential, and attenuate infarct size in animal models. Renal biology researchers investigate SS-31 protection against cisplatin nephrotoxicity and renal ischemia-reperfusion.
