SS-31 – COMPREHENSIVE RESEARCH PEPTIDE FOR MITOCHONDRIAL FUNCTION, OXIDATIVE STRESS, AND BIOENERGETIC STUDIES
Scientific Overview of SS-31
SS-31, also known as Elamipretide, is a synthetic tetrapeptide engineered to selectively target the inner mitochondrial membrane, where it interacts with cardiolipin to stabilize cristae structure and enhance electron transport efficiency. It has become a cornerstone compound in studies examining mitochondrial dysfunction, oxidative stress regulation, and cellular bioenergetics.
In in-vitro and in-vivo models, SS-31 has been investigated for its effects on:
• Mitochondrial Bioenergetics – evaluation of electron transport chain efficiency, ATP synthesis, and membrane potential stabilization (Szeto, 2008)
• Reactive Oxygen Species (ROS) Modulation – assessment of peptide-mediated reduction of mitochondrial oxidative stress and lipid peroxidation (Birk et al., 2013)
• Cellular Protection and Longevity – exploration of SS-31’s impact on mitochondrial integrity under ischemic, metabolic, and neurodegenerative conditions (Cho et al., 2017)
SS-31 serves as a key model peptide for mitochondrial-targeted therapeutic design, redox biology, and cellular resilience research. Its unique structure and lipophilic cationic properties allow for rapid mitochondrial uptake, making it indispensable in bioenergetic and aging-related studies.
