Met-Glu-His-Phe-Pro-Gly-ProMeccanismo d'azione
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.
Semax
Semax is a tetracosactide fragment analog without hormonal activity at MC2R. Proposed mechanisms include elevation of BDNF and NGF in hippocampus and striatum (in animal models), modulation of dopamine metabolism, and neuroprotective effects via anti-apoptotic pathways. A clear primary receptor is not established.

Frequently asked questions
- What is the difference between Plecanatid and Semax?
- Plecanatid is classified as "Ricerca (altro)", while Semax is classified as "Ricerca (altro)". 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). Semax: Synthetic heptapeptide derived from the N-terminal fragment of adrenocorticotropic hormone (ACTH 4-10). Approved in Russia for ischaemic stroke, cognitive function and ADHD in children. Western phase-3 trials absent. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Plecanatid or Semax?
- The highest available evidence level is "RCT sull'uomo" for Plecanatid and "Studio sull'uomo" for Semax. 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 Plecanatid and Semax in Germany and the United States?
- Germania: Plecanatid — Non approvato, Semax — Non approvato. Stati Uniti: Plecanatid — Su prescrizione, Semax — Non approvato. These are factual summaries with source and review date on the individual pages.
