Meccanismo d'azione

Elamipretide

Elamipretide is a cell-permeable tetrapeptide with alternating aromatic and basic residues that selectively concentrates on cardiolipin — a phospholipid found almost exclusively in the inner mitochondrial membrane that is important for cristae curvature and the organisation of the respiratory-chain complexes. By binding cardiolipin, elamipretide is proposed to stabilise cristae architecture, support electron transport and ATP production, and reduce the formation of reactive oxygen species. These mechanistic models derive largely from cell and animal models and biophysical work; the extent to which they explain clinical efficacy in humans is, given the mixed trial results, a matter of ongoing research.

Plecanatid

Plecanatide is structurally analogous to the body's own uroguanylin and, like it, activates the GC-C receptor at the gut surface, raising cGMP and fluid secretion. Its pH-dependent activity shifts the effect toward the proximal small intestine.

Frequently asked questions

What is the difference between Elamipretide and Plecanatid?: Elamipretide is classified as "Ricerca (altro)", while Plecanatid is classified as "Ricerca (altro)". Elamipretide: Elamipretide (SS-31, MTP-131, formerly Bendavia) is a synthetic, mitochondria-targeting tetrapeptide (sequence D-Arg-Dmt-Lys-Phe-NH2) that binds cardiolipin on the inner mitochondrial membrane and is proposed to stabilise cristae structure and support mitochondrial bioenergetics. It was investigated clinically by Stealth BioTherapeutics across several indications, including primary mitochondrial myopathy, Barth syndrome, heart failure, and dry age-related macular degeneration (geographic atrophy). The trial record is mixed, with several pivotal studies missing their primary endpoints. In September 2025 elamipretide (brand name Forzinity) received accelerated FDA approval in the United States solely for the ultra-rare Barth syndrome; for all other investigated indications it remains investigational and it is not approved as a medicine outside the United States. Plecanatid: Plecanatide is a 16-amino-acid analog of the body's own uroguanylin and a guanylate cyclase-C (GC-C) agonist. It is approved for chronic idiopathic constipation (CIC) and IBS with constipation (IBS-C). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Elamipretide or Plecanatid?: The highest available evidence level is "RCT sull'uomo" for Elamipretide and "RCT sull'uomo" for Plecanatid. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
What is the legal status of Elamipretide and Plecanatid in Germany and the United States?: Germania: Elamipretide — Non approvato, Plecanatid — Non approvato. Stati Uniti: Elamipretide — Su prescrizione, Plecanatid — Su prescrizione. These are factual summaries with source and review date on the individual pages.
