Research Overview

Exendin-4

Exendin-4 helped establish GLP-1 receptor biology in diabetes and remains a classic beta-cell protective peptide. Preclinical studies show reduced beta-cell apoptosis, improved insulin content, and better islet function under metabolic stress.

Insulin Degludec

Studies highlight prolonged action and lower glycemic variability compared with many other basal insulins. It is frequently used in research on ultra-long basal coverage and hypoglycemia reduction.
