Semaglutide emerged from Novo Nordisks systematic GLP-1 analogue optimisation programme as the successor to liraglutide , incorporating structural modifications addressing the three principal pharmacokinetic vulnerabilities of native GLP-1: DPP-IV susceptibility at position 8 addressed by Aib8 alpha-aminoisobutyric acid substitution, proteolytic cleavage at position 34 addressed by Arg34Lys substitution, and the short half-life of unmodified GLP-1 analogues addressed by the C18 fatty diacid conjugation providing tighter albumin binding and longer half-life than liraglutides C16 fatty acid, producing the approximately one-week half-life enabling once-weekly subcutaneous administration
Indeed, the potential promise of GLP-1(2836) as a synthetic peptide that enables GLP-1Rindependent, MTP-dependent, sAC-mediated cytoprotective cAMP signaling, with no effect on HR, is worthy of further exploration
Comparing them is not about declaring a winner, but about understanding how research evolves from a generalist agonist to a targeted one
