Compound guide

SS-31

A pathway-focused guide to molecular mechanisms, published evidence, and the limits of interpretation.

Overview

A Summary:SS-31

SS-31, also called elamipretide, is a short mitochondria-targeting tetrapeptide studied for its interaction with cardiolipin in the inner mitochondrial membrane.

Its cardiolipin interactions are investigated for effects on membrane organization, respiratory-chain efficiency, ATP production, and oxidative-stress responses.

SS-31 has substantial preclinical literature and has entered clinical trials in selected disorders, but findings are indication-specific and do not establish a general consumer benefit.

Research model

Cellular & MolecularHow SS-31 Is Studied

These receptors, enzymes, and signaling networks define the primary laboratory questions associated with this research material.

01Mitochondrial targeting

Cardiolipin membrane binding

At the cellular or molecular level

SS-31 associates with cardiolipin, a negatively charged phospholipid concentrated in the inner mitochondrial membrane. Cardiolipin helps organize membrane shape and respiratory proteins.

02Respiratory efficiency

Electron-transport organization

At the cellular or molecular level

Preclinical work suggests cardiolipin interactions can support cristae structure and the arrangement of electron-transport proteins, including the relationship between cardiolipin and cytochrome c.

03Oxidative-stress response

Redox balance

At the cellular or molecular level

By influencing membrane and electron-transport behavior, SS-31 is proposed to reduce excessive reactive-oxygen-species formation and downstream oxidative damage in stressed cells.

One important note

Educational Notice

SS-31 has been tested in human mitochondrial-disease trials. Early studies reported selected signals, while the larger MMPOWER-3 trial did not improve its primary walking-distance or fatigue endpoints.
