In the rapidly evolving landscape of advanced biochemical research, MTP 131—frequently referred to as SS-31 or Elamipretide—has emerged as a focal point for those interested in cellular bioenergetics. As an enthusiast documenting my own exploration into research compounds, I find the science behind this specific molecule to be one of the most fascinating development 13 Apr 2026—MTP-131 and SS-31 are the exact same peptide. A mitochondrial-targeting tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH₂. The naming Read more s in recent years. Whether you are searching for MTP-131 for laboratory study or are simply curious about how these compounds function, understanding the nuances of this mitochondria-targeted peptide MTP-131 is essential.
What Exactly is MTP 131?
At its core, MTP 131 is a small peptide, specifically a synthetic tetrapeptide with a cationic 3+ charge at physiological pH. This unique chemical structure is what allows it to selectively accumulate within the inner mitochondrial membrane. For those unfamiliar with the terminology, it is important to note that MTP-131 and SS-31 are the exact same peptide. It is also known by the development name Elamipretide (formerly MTP 131).
When I first began researching this compound, I learned that it is a tetrapeptide compound being developed by Stealth Therapeutics. The primary interest among researchers is its role as an efficacious antioxidant that is a mitochondria-targeting What Is MTP-131 Same as SS-31? (Mitochondrial Research peptide. By localizing specifically to the mitochondria, it helps in restoring mitochondrial superoxide levels with Elamipretide (MTP-131), which is critical for maintaining cellular homeostasis.
The Role of Mitochondria-Targeted Technology
The interest in peptides—and specifically this class of mo Mitochondrial Targeted Therapy with Elamipretide (MTP-131 lecules—stems from their ability to interact with cellular structures at a granular level Serendipity and the Discovery of Novel Compounds That . Many researchers are drawn to the potential of these compounds because they emerge as a promising candidate in combating mitochondrial dysfunction-related disorders.
In my own review of the literature, I have observed that MTP 131 is a mitochondria-targeted peptide antioxidant that has been studied in various contexts. For example, it is currently being investigated in several Phase 2 clinical trials for heart failure. Furthermore, it is noteworthy that there is a Global Phase 3 Clinical Program for Elamipretide currently underway, highlighting the significant investment in this technology.
Practical Considerations for Research Use
If you are looking into sourcing these compounds, it is clear that SS-31 peptide, also known as Elamipretide, Bendavia, or MTP-131, is available for research purposes from multiple suppliers. As someone who values quality, I always emphasize that the integrity of the peptide sequence (D-Arg-Dmt-Lys-Phe-NH2) is paramount for any experimental outcome.
It is interesting to follow the regulatory journey of these molecules. We have seen news regarding the FDA approval of Stealth's mitochondria-targeted therapy, which has sparked widespread discussion about the future of Stealth BioTherapeutics' pipeline. While Elamipretide (MTP-131, SS-31) has been recognized for its potential, it is also 17 Jul 2020—This randomized, double-blind, placebo-controlled, crossover study screened 32 subjects with primary mitochondrial myopathy (PMM) to important to remember that it is a medication used for the treatment of Barth syndrome, which underscores the serious nature of the research being conducted.
Final Thoughts on the Future of MTP 131
The fascination with 131 and its related compounds will likely continue as more data is published. My experience with these peptides has shown me that the precision with which they target the "powerhouse of the cell" is what set 9 Oct 2025—FDA approval of Stealth's mitochondria-targeted therapycould pave the way for a host of longevity biotech companies. s them apart from conventional antioxidants. Whe 1238 MTP131, a cardiolipintargeting peptide, improves ther it is through the lens of longevity research or the study of metabolic efficiency, the work surrounding MTP remains at the forefront of modern biochemical inquiry.
As with any advanced research material, ensure you are sourcing from reputable suppliers who provide high-purity, verified products. Understanding that MTP-131 is a specialized tool for mitochondrial research is the first step toward a deeper appreciation of this complex and evolving field.
