SS-31 (Elamipretide) — Research Overview

SS-31 (Elamipretide) is a synthetic water-soluble tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH₂, engineered to selectively target and accumulate within the inner mitochondrial membrane. Its mechanism of action centers on two distinct properties — its ability to bind to cardiolipin, a phospholipid essential to the structural integrity of mitochondrial cristae and electron transport chain function, and its capacity to scavenge reactive oxygen species at their primary site of generation through its dimethyltyrosine residue. This precise mitochondrial targeting distinguishes it from broad-spectrum antioxidants and has made it a compound of significant interest in research examining cellular bioenergetics, oxidative stress, apoptosis, and mitochondrial dysfunction across multiple tissue types. Available from 4-LD in 30mg lyophilized form, SS-31 is produced under quality-controlled conditions exclusively for qualified researchers and laboratory professionals conducting in-vitro research applications.

Areas of Active Research

SS-31 has been studied across several active research areas. In ischemia-reperfusion injury research, cell culture and animal models of kidney, cardiac, and neural tissue have examined its potential to prevent mitochondrial permeability transition pore opening and cytochrome c release during reperfusion events, with findings in renal and cardiac models documenting preservation of tissue function and reduced cell death markers following SS-31 treatment. In cardiac and cardiomyopathy research, primary cardiomyocyte and porcine models have investigated its effects on infarct size reduction, mitochondrial membrane potential preservation, and calcium handling under hypoxia and reoxygenation conditions. In neurological and age-related cellular research, studies have examined its effects on mitochondrial structure and function in neuronal models subjected to oxidative stressors including rotenone and amyloid-beta, with findings suggesting protection of cristae structure and improved ATP production capacity in aged and stressed cell models. In skeletal muscle and sarcopenia research, in-vitro studies using myotube models have explored its influence on mitochondrial content, ROS production, and expression of atrophy and biogenesis regulators under atrophic conditions. All findings referenced are from preclinical and in-vitro studies.
