ECHEMI Editorial Reference

Semaglutide (CAS: 910463‑68‑2) is a synthetic lipid‑modified peptide analogue, consisting of a 31‑amino‑acid backbone with a covalently attached C18 fatty di‑acid side‑chain via a hydrophilic spacer. It shares 94% amino‑acid sequence homology with native human GLP‑1 peptide. The substance appears as white to almost white hygroscopic powder, with molecular formula C₁₈₇H₂₉₁N₄₅O₅₉ and molecular weight of 4113.58 g/mol. Structural modifications grant it resistance against DPP‑4 enzymatic degradation and enable reversible binding to serum albumin, contributing to its extended in‑vivo half‑life property.

Class:

GLP-1R agonist

Status:

FDA-approved (Ozempic / Wegovy / Rybelsus)

Mechanism:

Long-acting, selective glucagon-like peptide-1 (GLP-1) receptor agonist with 94% sequence homology to human GLP-1. Engineered for extended half-life (~1 week) via albumin binding (fatty acid acylation at Lys26) and resistance to DPP-4 degradation (Aib substitution at position 8). Promotes insulin secretion, inhibits glucagon release, delays gastric emptying, and reduces appetite via central nervous system GLP-1R activation.

Activity note:

Potent, selective GLP-1R agonist. Reported binding affinity Ki = 0.38 ± 0.06 nM. Semaglutide is a human GLP-1 analog with structural modifications for albumin binding (C18 fatty diacid at Lys26) and enzymatic stability (Aib8 substitution).
