Met-Glu-His-Phe-Pro-Gly-ProMeccanismo d'azione
Linaclotid
Linaclotide activates the guanylate cyclase-C receptor on the luminal surface of the intestinal epithelium. This raises cyclic GMP (cGMP), increases secretion of chloride and bicarbonate into the lumen, raises stool fluid content and accelerates transit; pain signaling is also modulated.
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 Linaclotid and Semax?
- Linaclotid is classified as "Ricerca (altro)", while Semax is classified as "Ricerca (altro)". Linaclotid: Linaclotide is a 14-amino-acid peptide and guanylate cyclase-C (GC-C) agonist. It is approved for irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC). 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, Linaclotid or Semax?
- The highest available evidence level is "RCT sull'uomo" for Linaclotid 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 Linaclotid and Semax in Germany and the United States?
- Germania: Linaclotid — Su prescrizione, Semax — Non approvato. Stati Uniti: Linaclotid — Su prescrizione, Semax — Non approvato. These are factual summaries with source and review date on the individual pages.
