About Liraglutide
Liraglutide — the active ingredient in Victoza® and Saxenda® (CAS 204656-20-2) — is a long-acting GLP-1 receptor agonist with a C16 fatty acid chain (palmitoyl) attached via a glutamic acid linker to Lys²⁶, enabling reversible albumin binding and an extended half-life of ~13 hours (versus ~2 minutes for native GLP-1). It is supplied as a laboratory-grade lyophilized powder intended strictly for analytical and non-clinical research applications.
Unlike native GLP-1(7-37), liraglutide is resistant to DPP-4 degradation due to Arg³⁴Lys and Lys²⁶ modifications. It activates GLP-1R (a Gs-coupled GPCR) to stimulate glucose-dependent insulin secretion, suppress glucagon, and delay gastric emptying. As the first once-daily GLP-1 agonist approved for both T2DM and obesity, liraglutide has extensive characterization across pancreatic β-cell, hypothalamic appetite circuit, and hepatic metabolic signaling research. Researchers use liraglutide in MIN6, INS-1, and primary islet models for β-cell GLP-1R/cAMP/PKA signaling studies, and in hypothalamic neuronal models (N41 cells) for appetite circuit mapping comparative to semaglutide and other next-generation GLP-1RAs.
COMMON RESEARCH APPLICATIONS
GLP-1R Pharmacology & β-Cell Signaling
Used in MIN6, INS-1E, and HEK293-GLP1R models to study GLP-1R agonist-driven cAMP/PKA/CREB pathway activation, glucose-stimulated insulin secretion (GSIS) augmentation, β-arrestin recruitment, and receptor desensitization under once-daily dosing simulation protocols.Incretin Axis & Glucagon Suppression Research
Tool compound for studying GLP-1R-mediated glucagon suppression in α-cell (αTC1-6) models and insulin/glucagon co-secretion dynamics in isolated islet models; used to map incretin axis signaling under normoglycemic vs. hyperglycemic challenge conditions.Hypothalamic Appetite Circuit Research
Used in N41, GT1-7, and primary hypothalamic neuron models to study GLP-1R-driven POMC/CART pathway activation, NPY/AgRP suppression, and appetite-regulatory neural signaling at the arcuate nucleus level.Comparative GLP-1R Agonist Benchmarking
First-generation long-acting GLP-1RA reference standard for comparing receptor activation kinetics, cAMP response magnitude, and β-arrestin bias ratios against semaglutide (C18 diacid), dulaglutide (IgG fusion), and next-generation GLP-1RAs in head-to-head receptor pharmacology studies. -
