Comparison

Exenatide vs FOXO4-DRI

Function

While 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, FOXO4-DRI acts as a senolytic in preclinical models by promoting apoptosis of senescent cells, improving tissue function and healthspan measures in aged animals38.

Mechanism

While Exenatide works as 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, FOXO4-DRI is a D-retro-inverso peptide derived from a FOXO4 region that competes with endogenous FOXO4 for binding to p53, thereby releasing p53 to trigger apoptosis selectively in senescent cells38.

Length and Sequence

Exenatide is 39 amino acids long, whereas FOXO4-DRI is shorter as it has a length of amino acids. Exenatide is made up of a sequence of sequence data not available in the current dataset. FOXO4-DRI is made up of a sequence of sequence data not available in the current dataset.

Receptor

Exenatide

GLP-1 receptor (GLP1R) 6780

FOXO4-DRI

Intracellular target is the FOXO4–p53 protein–protein interaction interface; it does not signal via a traditional cell-surface receptor38

Organism or Origin

Exenatide

Originally from Heloderma suspectum (Gila monster) venom; now produced synthetically67

FOXO4-DRI

Synthetic peptide based on human FOXO4 transcription factor3898
