In the realm of biochemical research and the pursuit of enhanced cellular health, peptides have emerged as fascinating molecules with profound therapeutic potential. Among these, SS-31, also known by its developmental names Elamipretide or MTP-131, has garnered significant attention for its unique ability to target and protect mitochondria. As a leading supplier of high-quality research peptides, we are proud to offer SS-31 and delve into the science that makes it a critical component for studies in mitochondrial health, aging, and various physiological processes.

Understanding Mitochondria: The Powerhouses of Our Cells

Mitochondria are often described as the powerhouses of the cell, responsible for generating the majority of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy. Their function is critical for overall cellular health, energy production, and the regulation of various cellular processes, including metabolism, cell signaling, and apoptosis. As we age, or under conditions of stress and disease, mitochondrial function can decline, leading to reduced energy production, increased oxidative stress, and contributing to age-related diseases.

SS-31: A Targeted Approach to Mitochondrial Protection

SS-31 is a synthetic peptide belonging to the Szeto-Schiller (SS) family, specifically designed to target the inner mitochondrial membrane. Its unique structure allows it to accumulate in this critical cellular component. The primary mechanism of action for SS-31 involves binding to cardiolipin, a vital phospholipid found exclusively in the inner mitochondrial membrane. Cardiolipin plays a crucial role in maintaining the structural integrity of the mitochondrial membrane and organizing the electron transport chain, which is essential for efficient ATP production.

Key Benefits and Mechanisms of SS-31:

  • Mitochondrial ROS Scavenging: SS-31 acts as a potent antioxidant within the mitochondria, effectively scavenging reactive oxygen species (ROS). By reducing oxidative stress, it protects mitochondrial DNA and proteins from damage, thereby preserving mitochondrial function.
  • Improved Mitochondrial Respiration and ATP Production: By stabilizing cardiolipin and optimizing the electron transport chain, SS-31 enhances mitochondrial respiration, leading to increased ATP synthesis. This translates to improved cellular energy production.
  • Inhibition of Mitochondrial Permeability Transition Pore (MPTP) Opening: Under conditions of cellular stress, the MPTP can open, leading to mitochondrial swelling and cell death. SS-31 has been shown to inhibit MPTP opening, thus preventing this damaging cascade.
  • Protection Against Age-Related Decline: Preclinical studies suggest that SS-31 can combat age-related mitochondrial dysfunction, improving exercise tolerance and muscle function in aged models.
  • Neuroprotection: Research indicates SS-31's potential to protect neurons from damage in models of neurodegenerative diseases by reducing oxidative stress and inflammation in the brain.

Applications in Research and Beyond
