El avance de los fármacos GLP-1 redefine el tratamiento de la obesidad en Estados Unidos - Infobae
The evolutionary path from venom to synthetic drug The progression from exendin-4 to modern GLP-1 medications followed three generations of engineering: Generation 1: Direct venom analog (2005) Exenatide (Byetta, Bydureon) Synthetic copy of exendin-4 with minimal modification Twice-daily injection initially, later extended-release weekly version Half-life: 2.4 hours (immediate-release), 2 weeks (extended-release) Still contains the 39-amino-acid exendin-4 sequence Generation 2: Modified human GLP-1 (2010-2014) Liraglutide (Victoza, Saxenda) Dulaglutide (Trulicity) Started with human GLP-1 sequence, not exendin-4 Added fatty acid side chains to bind to albumin in blood, preventing DPP-4 access Half-life: 13 hours (liraglutide), 5 days (dulaglutide) Daily or weekly injection depending on formulation Generation 3: Optimized synthetic analogs (2017-present) Semaglutide (Ozempic, Wegovy, Rybelsus) Tirzepatide (Mounjaro, Zepbound) Further modifications to human GLP-1 structure Semaglutide: 94% identical to human GLP-1, with three amino acid substitutions and a fatty acid chain Half-life: 7 days (semaglutide), 5 days (tirzepatide) Weekly injection or daily oral tablet Each generation moved further from the original Gila monster peptide
