mtp 131 peptide mitochondria-targeting tetrapeptide

Published October Oct 17, 2026 6:19 PM

In the evolving field of biochemical research, few compounds have captured as much interest as the MTP 131 peptide. Often referred to in scientific literature by its developmental names, such as SS-31 or Bendavia, this compound represents a fascinating area of study regarding cellular energy pathways. My journey into understanding this molecule began with a deep dive into its unique chemical structure and the specific way it interacts with cellular components.

Understanding the Molecule: What is MTP 131?

At its core, the MTP 131 molecule is a synthetic tetrapeptide. Its formal chemical structure, often identified as D-Arg-dimethyl-Tyr-Lys-Phe-NH2, gives it a cationic 3+ charge at physiological pH. This specific charge is crucial, as it allows the molecule to selectively concentrate over by S Russo·2022·Cited by 28—Chronic therapy with elamipretide (MTP-131), a novel mitochondria-targetingpeptide, improves left ventricular and mitochondrial function in Read more 1,000-fold in the inner mitochondrial membrane.

For those looking into the technical speci Elamipretide | C32H49N9O5 | CID 11764719 - PubChem - NIH fications, MTP 131 is a mitochondria-targeted peptide antioxidant. Unlike general antioxidants that disperse throughout the cell, this mitochondria-targeting peptide is designed to localize specifically where the energy production occurs. Many researchers observe that MTP-131 inhibits lipid peroxidation and prevents mitochondrial swelling, which are key markers of cellular stress.

Throughout my review of the available research, it becomes clear that SS-31 is a synthetic tetrapeptide that emerges as a promising candidate in combating mitochondrial dysfunction-related disorders. Because it is a small mitochondrially-targeted tetrapeptide, it possesses the necessary permeability to cross cell membranes efficiently.

Key Characteristics and Research Observations

When analyzing the data, several distinct features stand out:

* Targeted Delivery: It is a mitochondria-targeting tetrapeptide that acts as a cytochrome c peroxidase inhibitor.

* Antioxidant Properties: As SS-31, a mitochondria-targeting antioxidant, it serves a vital role in research models investigating the reduction of reactive oxygen species (ROS).

* Structural Classification: Often described as an oligopeptide, its specific amino acid sequence is what allows it to function effectively within the mitochondrial matrix.

Whether you are looking for MTP-131 raw powder for laboratory analysis or studying the broader applications of this mitochondrial-targeted peptide (MTP), the consistency in the literature is notable. It is frequently noted that elamipretide (MTP-131) has been studied for its potential to support cellular resilience.

Final Thoughts on Research Directions

It is important to distinguish that while elamipretide (MTP-131, SS-31) is a medication used for the treatment of Barth syndrome in clinical settings, the broader interest in the peptide community focuses on its role in basic science. MTP-131 is a mitochondrial-targeted tetrapeptide that continues to be a focal point for those interested in mitochondrial health.
