Escherichia coli were harvested by centrifugation and resuspended in HEPES buffer (20 mM HEPES, 300 mM NaCl, pH 7.4)
Triple agonist: By combining these three signaling pathways, retatrutide differs from GLP-1 receptor agonists such as semaglutide or liraglutide and from dual-acting active ingredients such as tirzepatide
The peptide is structurally derived from native human GLP-1(7-37) with two amino acid substitutions (Aib at position 8 for DPP-IV resistance, Arg substitution at position 34) and a C18 fatty diacid moiety conjugated via a Glu-(AEEA) linker enabling reversible albumin binding and an extended pharmacokinetic profile compatible with once-weekly dosing
