Research Overview
Oxyntomodulin
Human studies showed acute reductions in food intake and modest weight loss, helping establish the GLP-1 and glucagon co-agonism concept. It remains a foundational peptide for obesity and satiety research.
Lixisenatide
Lixisenatide produces small but measurable weight loss in diabetes trials while improving postprandial glucose excursions. Its shorter half-life makes it a useful reference compound for first-generation incretin mimetics.
