CP-1S — Acylated GLP-1 Receptor Agonist for Advanced Peptide Research
CP-1S is an acylated GCG-like peptide-1 (GLP-1) receptor agonist research compound engineered through systematic lipidation chemistry to achieve an extended pharmacokinetic profile of approximately 165–184 hours. As a 31-amino acid synthetic analog of human GLP-1(7-37) with 94% sequence homology to the endogenous hormone, CP-1S represents the culmination of iterative structure-activity relationship (SAR) studies spanning fatty acid chain lengths from C-12 to C-20, multiple linker chemistries, and strategic amino acid substitutions — all designed to optimize the balance between albumin binding affinity and GLP-1 receptor (GLP-1R) activation potency. This research compound is supplied exclusively as a high-purity lyophilized powder for in vitro and preclinical laboratory investigation. For research use only. Not for human consumption.
CP-1S occupies a unique position in peptide research due to its well-characterized structural biology, with high-resolution cryo-electron microscopy (cryo-EM) structures of the compound bound to the GLP-1R–Gs protein complex now available in the Protein Data Bank (PDB: 7KI0). This structural detail, combined with extensive published literature on the compound’s intracellular signaling profile, receptor dynamics, and activity across diverse preclinical metabolic models, makes CP-1S an exceptionally well-documented tool compound for investigators studying GLP-1 receptor pharmacology, acylated peptide drug design, incretin biology, and metabolic pathway modulation in laboratory settings.
