Comparison

Dulaglutide vs Exenatide

Function

While Dulaglutide is a once-weekly GLP-1RA for type 2 diabetes that lowers HbA1c and body weight by enhancing glucose-dependent insulin secretion and reducing appetite6668, Exenatide is used for type 2 diabetes treatment to improve glycemic control and modestly reduce body weight through GLP-1–like insulinotropic and glucagonostatic effects6768.

Mechanism

While Dulaglutide works as a recombinant fusion protein consisting of two disulfide-linked GLP-1(7–37) analogs each covalently fused via a linker to an IgG4 Fc fragment, yielding a large, long-acting GLP-1 receptor agonist protected from DPP-4 degradation66, Exenatide is a 39-amino-acid exendin-4 peptide originally isolated from Gila monster venom that acts as a long-acting GLP-1 receptor agonist resistant to DPP-4 degradation67.

Length and Sequence

Dulaglutide is amino acids long, whereas Exenatide is longer as it has a length of 39 amino acids. Dulaglutide is made up of a sequence of sequence data not available in the current dataset. Exenatide is made up of a sequence of sequence data not available in the current dataset.
