Product Detail

1. Product Introduction SS‑31 is a synthetic tetrapeptide composed of four amino‑acid residues. CAS No.: 736992‑21‑5 It is available for laboratory research on receptor binding characteristics and intracellular biochemical signaling under cell experimental systems. All related research data apply only to in vitro laboratory environments. This product is lyophilized powder, for laboratory research use only. It shall not be administered to human beings or used in clinical trials for any medical purposes.

2. Product Characteristic Features SS‑31 is manufactured via standard solid‑phase synthesis and HPLC purification process. The finished lyophilized powder maintains stable molecular conformation and good water solubility. Vacuum freeze‑drying process slows molecular degradation and keeps molecular structure stable during transportation and low‑temperature storage.

3. Main Research Application Directions For in vitro laboratory experimental research only: Fundamental study on interaction between polypeptide and receptor Exploration of peptide‑mediated intracellular signal transduction within cell models Research on molecular interaction of synthetic tetrapeptide Stability comparison test of polypeptide under different solvent and culture conditions Biochemical exploration for peptide‑related signal pathways

ECHEMI Editorial Reference

Elamipretide has been used in trials studying the treatment of Leber's Hereditary Optic Neuropathy.
Elamipretide, also known as MTP 131, is a mitochondria-targeted peptide antioxidant. Elamipretide decreases inflammation and protect against a variety of neurological illnesses. Elamipretide (SS-31) improves mitochondrial dysfunction, synaptic and memory impairment induced by lipopolysaccharide in mice. Elamipretide Promotes Mitophagosome Formation and Prevents Its Reduction Induced by Nutrient Excess in INS1 β-cells.
Elamipretide Synthetic is a single, non-glycosylated polypeptide chain containing 4 amino acids, having a molecular mass of 640 Dalton and a Molecular formula of C32H49N9O5 .

Research

Class:

Mitochondria-targeted tetrapeptide (Szeto-Schiller peptide)

Status:

FDA-approved (Forzinity) — Accelerated Approval 2025

Mechanism:

A cell-permeable, synthetic tetrapeptide (D-Arg-Dmt-Lys-Phe-NH₂) that selectively concentrates in the inner mitochondrial membrane and reversibly binds to cardiolipin, a phospholipid essential for electron transport chain (ETC) function. By stabilizing cardiolipin, SS-31 restores mitochondrial bioenergetics, reduces cytochrome c peroxidase activity, and prevents oxidative damage in cells with impaired mitochondrial function.

Activity note:

SS-31 does not act via traditional receptor agonism. It binds cardiolipin with high selectivity in the inner mitochondrial membrane. Functional EC₅₀ values are context-dependent (cell type, stress model). Key electrophysiology studies report mitochondrial membrane potential restoration at nanomolar concentrations.
