Werkingsmechanisme
Dulaglutide
Dulaglutide consists of two modified GLP-1(7-37) sequences covalently linked to a human IgG4-Fc. The Fc fusion increases molecular weight substantially (~60 kDa), reduces renal filtration and extends the half-life to several days. GLP-1 receptor activation glucose-dependently stimulates insulin secretion, inhibits glucagon, delays gastric emptying and modulates central satiety signalling.
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.

Frequently asked questions
- What is the difference between Dulaglutide and Ecnoglutide?
- Dulaglutide is classified as "Metabool", while Ecnoglutide is classified as "Metabool". Dulaglutide: GLP-1 receptor agonist designed as a fusion protein of two modified GLP-1(7-37) sequences covalently linked to a human IgG4-Fc fragment. FDA-approved 2014 (Trulicity) for type 2 diabetes; EMA approval 2014. 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. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Dulaglutide or Ecnoglutide?
- The highest available evidence level is "Humane RCT" for Dulaglutide and "Humane RCT" for Ecnoglutide. 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 Dulaglutide and Ecnoglutide in Germany and the United States?
- Duitsland: Dulaglutide — Op recept, Ecnoglutide — Niet goedgekeurd. Verenigde Staten: Dulaglutide — Op recept, Ecnoglutide — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
