• 产品描述： Exendin-4 (Exenatide), a 39 amino acid peptide, is a long-acting glucagon-like peptide-1 receptor agonist with an IC50 of 3.22 nM.

• 靶点： IC50: 3.22 nM (glucagon-like peptide-1 receptor)

• 体内研究： Both low- and high-dose exendin-4 treatment in ob/ob mice improve serum ALT and reduce serum glucose, and calculated HOMA scores compared with control. Exendin-4-treated ob/ob mice sustain a marked reduction in the net weight gain in the final 4 weeks of the study period. Animals treated with exendin-4 have more pancreatic acinar inflammation, more pyknotic nuclei and weigh significantly less than control rats. Exendin-4 treatment is associated with lower leptin levels as well as lower HOMA values in rats. Exenatide causes dose-dependent relaxation of rat thoracic aorta, which is evoked via the GLP-1 receptor and is mediated mainly by H2S but also by NO and CO.
