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.
Lixisenatide
Lixisenatide is a 44-amino-acid peptide based on exendin-4 (see exenatide) with six additional lysine residues at the C-terminus. This modification increases stability against DPP-4 degradation. The short half-life (~3 hours) and plasma peak around mealtime explain the predominantly prandial effect — stronger postprandial glucose action, weaker fasting glucose effect than weekly GLP-1 RAs.

Frequently asked questions
- What is the difference between Ecnoglutide and Lixisenatide?
- Ecnoglutide is classified as "Метаболизм", while Lixisenatide is classified as "Метаболизм". 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. Lixisenatide: Synthetic exendin-4 analog with a C-terminal lysine extension. Prandial GLP-1 RA focused on postprandial glucose. FDA-approved 2016 as Adlyxin; EMA-approved 2013 as Lyxumia. Sanofi discontinued US distribution in 2023. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Ecnoglutide or Lixisenatide?
- The highest available evidence level is "РКИ на людях" for Ecnoglutide and "РКИ на людях" for Lixisenatide. 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 Lixisenatide in Germany and the United States?
- Германия: Ecnoglutide — Не одобрено, Lixisenatide — Рецептурный. США: Ecnoglutide — Не одобрено, Lixisenatide — Не одобрено. These are factual summaries with source and review date on the individual pages.
