Semaglutide

Overview

Researchers planning incretin-pathway investigation can buy Semaglutide research peptide from Advanced Peptide Science at 99%+ HPLC-verified purity. Semaglutide is a 31-amino-acid GLP-1 receptor agonist (94% homology to native human GLP-1) extensively investigated in preclinical insulin secretion, CNS appetite regulation, and cardiovascular research models.

Bacteriostatic Water (BAC Water) 30ml is required for reconstitution of this lyophilized compound. Available separately: Bacteriostatic Water 30ml.

Research Background

Semaglutide emerged from second-generation GLP-1 analogue research lineages building on Liraglutide. The structural modification of α-aminoisobutyric acid (Aib) at position 8 confers DPP-4 protease resistance, while the C18 fatty-diacid linker attached via Lys26 enables strong albumin binding and a substantially extended preclinical half-life relative to native GLP-1. The compound has become a comparative standard in metabolic peptide research.

Mechanism of Action (Research Context)

Mechanism research investigates Semaglutide’s high-affinity binding at the GLP-1 receptor (GLP-1R), a class B GPCR coupled to Gs/cAMP signalling. Downstream pathways under investigation include glucose-dependent insulin secretion from pancreatic beta cells, glucagon suppression, delayed gastric emptying, and central appetite-circuit modulation via GLP-1R expression in the arcuate nucleus, area postrema, and nucleus tractus solitarius.

Research Applications

• GLP-1 receptor pharmacology and signalling cascade research
• Glucose-dependent insulin secretion and beta-cell function studies
• CNS appetite-circuit modulation in preclinical models
• Cardiovascular risk marker investigation in metabolic models
• Comparative incretin research vs Tirzepatide and Retatrutide
