Werkingsmechanisme
Ecnoglutide
Ecnoglutide is a modified GLP-1(7-37) peptide with an alanine-to-valine substitution at position 8 and an 18-C fatty-acid conjugation at the lysine-30 side chain. It is a so-called biased agonist: at the GLP-1 receptor it preferentially induces cAMP formation while β-arrestin recruitment is reduced. In preclinical models this has been linked to lower receptor internalisation and desensitisation. GLP-1 receptor activation is mechanistically associated with enhanced glucose-dependent insulin secretion, delayed gastric emptying and satiety signalling. The fatty-acid conjugation enables weekly administration via albumin binding.
Petrelintide
As an amylin analogue, petrelintide acts through amylin receptors, promoting satiety and slowed gastric emptying — a satiety pathway independent of the GLP-1 axis.

Frequently asked questions
- What is the difference between Ecnoglutide and Petrelintide?
- Ecnoglutide is classified as "Metabool", while Petrelintide is classified as "Metabool". Ecnoglutide: Ecnoglutide (XW003) is a long-acting, cAMP-signalling-biased GLP-1 analogue from Sciwind Biosciences. Derived from GLP-1(7-37) with an alanine-to-valine substitution at position 8, it activates the GLP-1 receptor selectively via the cAMP pathway over β-arrestin recruitment. Investigated for weight management and in type 2 diabetes. Petrelintide: Petrelintide is a long-acting amylin analogue (Zealand Pharma, with Roche) for once-weekly subcutaneous use — developed for weight management with a focus on strong tolerability. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Ecnoglutide or Petrelintide?
- The highest available evidence level is "Humane RCT" for Ecnoglutide and "Humane RCT" for Petrelintide. 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 Ecnoglutide and Petrelintide in Germany and the United States?
- Duitsland: Ecnoglutide — Niet goedgekeurd, Petrelintide — Niet goedgekeurd. Verenigde Staten: Ecnoglutide — Niet goedgekeurd, Petrelintide — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
