Comparison

FOXO4-DRI vs Tirzepatide

Function

While FOXO4-DRI acts as a senolytic in preclinical models by promoting apoptosis of senescent cells, improving tissue function and healthspan measures in aged animals38, Tirzepatide is approved for type 2 diabetes and obesity, producing larger HbA1c and body-weight reductions than semaglutide in head-to-head trials24.

Mechanism

While FOXO4-DRI works as 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, Tirzepatide is a 39-amino-acid synthetic peptide primarily based on GIP sequence with C20 fatty diacid conjugation that acts as a dual agonist at GIP and GLP-1 receptors, enhancing glucose-dependent insulin secretion, suppressing glucagon, delaying gastric emptying, and reducing appetite24.

Length and Sequence

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

Receptor

FOXO4-DRI

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

Tirzepatide

Glucose-dependent insulinotropic polypeptide receptor (GIPR) and GLP-1 receptor (GLP1R) 24
