Comparison

FOXO4-DRI vs Hexarelin

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, Hexarelin is investigated for effects on GH secretion, cardiac protection, and muscle metabolism, with higher GH secretory potency than earlier GHRPs1929.

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, Hexarelin is a potent synthetic hexapeptide (examorelin) that agonizes GHSR-1a to stimulate GH release and also binds CD36, influencing cardiovascular and metabolic pathways19212996.

Length and Sequence

FOXO4-DRI is amino acids long, whereas Hexarelin is longer as it has a length of 6 amino acids. FOXO4-DRI is made up of a sequence of sequence data not available in the current dataset. Hexarelin is made up of a sequence of Histidine, Tryptophan, Alanine, Tryptophan, Phenylalanine, Lysine.

Receptor

FOXO4-DRI

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

Hexarelin

Primary: GHSR-1a (ghrelin receptor); also binds the scavenger receptor CD36 in vascular and macrophage tissues192129

Synthetic peptide based on human FOXO4 transcription factor3898

Hexarelin
