Exenatide acetate (Exendin-4 Acetate), a bioactive peptide composed of 39 amino acids, is antidiabetic medication acting as a long-acting glucagon-like peptide-1 receptor agonist with an IC50 of 3.22 nM. Exenatide, a synthetic version of endogenous glucagon-like peptide-1, suppresses hunger, inhibits the release of glucagon, increases insulin secretion, and slows stomach emptying. It is therefore utilized as supplemental therapy for diabetes mellitus.

ln Vitro |
Exendin-4 dramatically and dose-dependently raises NO production, phosphorylation of endothelial NO synthase (eNOS), and GTP cyclohydrolase 1 (GTPCH1) in human umbilical vein endothelial cells[2]. MCF-7 breast cancer cells exhibit cytotoxic effects from exendin-4, with an IC50 of 5 μM after 48 hours[3].
|
ln Vivo |
Exendin-4 treatment, at both low and high doses, improves serum ALT and lowers serum glucose levels in ob/ob mice as well as computes HOMA scores in comparison to control. In the last four weeks of the study, the net weight gain of the ob/ob mice treated with extendin-4 is significantly reduced[4]. The Exendin-4-treated animals weigh a great deal less than the control rats and exhibit increased pyknotic nuclei and pancreatic acinar inflammation. Rats treated with extendin-4 have lower HOMA values and lower levels of leptin[5]. The rat thoracic aorta relaxes in response to exenatide in a dose-dependent manner. This relaxation is mediated primarily by H2S but also by NO and CO, and it is evoked through the GLP-1 receptor[6].

Animal Protocol |
Rats: 20 Sprague-Dawley male rats, ten of which are treated with exendin-4 (10 μg/kg) and ten of which are used as controls. There are 75 days in the study period. Pancreatic tissue and serum are extracted for histological and biochemical analysis. The two groups' levels of blood glucose, lipase, amylase, and adipocytokines are compared[5].
Mice: For the first 14 days, 10 μg/kg is administered to the exendin-4 treatment groups every 24 hours. This therapy is the initiating stage. Every 24 hours, the corresponding control mice (lean and ob/ob) are given saline. Exendin-4-treated mice are split into two groups at random after 14 days: the first group is given a high dose of exendin-4 (20 μg/kg) every 12 hours, while the second group is given a low dose of exendin-4 (10 μg/kg) every 12 hours. Every twelve hours, saline is still given to the control mice. Every day for the duration of the 60-day treatment, the mice are weighed[4]. |
