PEPTIDE RESEARCH TRENDS TO WATCH IN 2026
Research VialsThe five biggest trends shaping peptide research in 2026 — from GLP-1 agonist evolution to mitochondrial peptides, AI-driven discovery, and the post-Peptide Sciences landscape.
ARD-101, A GUT-RESTRICTED TAS2R AGONIST, REDUCES HUNGER IN ADULTS AND PROMOTES WEIGHT LOSS IN DIO MICE WITH DPP-4 INHIBITION.
PubMed · Molecular metabolismZheng Z et al., Molecular metabolism · 2026 Apr. PMID 41833222.
METAVIA'S GLP-1/GCGR DUAL AGONIST HITS 9.1% WEIGHT LOSS IN 54 DAYS...
Longevity TechnologyMetaVia's DA-1726 — a once-weekly GLP-1R/GCGR (glucagon-like peptide-1 and glucagon receptor) dual agonist — produced average body weight reductions of 9.1% by day 54 in its highest-dose Phase 1 cohort. Waist circumference dropped nearly 6 cm in the same window. The data, presented at the American Diabetes Association 2026 Scientific Sessions, put DA-1726 in direct competition with the semaglutide and tirzepatide class — but with a dual-receptor mechanism that may hit fat tissue harder.
