Overview

FOXO4-DRI is classified as a senolytic peptide peptide. Senescent cell elimination (senolytics), longevity, tissue rejuvenation, SASP reduction.

D-retro-inverso peptide that disrupts the interaction between FOXO4 and p53 in senescent cells. In normal cells, FOXO4 retains p53 in the nucleus preventing apoptosis — a mechanism senescent cells exploit for survival. FOXO4-DRI competitively binds FOXO4, freeing p53 to migrate to mitochondria, triggering apoptosis selectively in senescent cells. Results in clearance of senescent cell burden, reduction of the senescence-associated secretory phenotype (SASP), and tissue rejuvenation markers in aged mice.

How Does FOXO4-DRI Work?

D-retro-inverso peptide that disrupts the interaction between FOXO4 and p53 in senescent cells. In normal cells, FOXO4 retains p53 in the nucleus preventing apoptosis — a mechanism senescent cells exploit for survival. FOXO4-DRI competitively binds FOXO4, freeing p53 to migrate to mitochondria, triggering apoptosis selectively in senescent cells. Results in clearance of senescent cell burden, reduction of the senescence-associated secretory phenotype (SASP), and tissue rejuvenation markers in aged mice.

At the molecular level, FOXO4-DRI operates through pathways characteristic of the Senolytic Peptide class, interacting with target receptors and downstream signaling cascades to produce its observed effects.

Safety Profile

⚠ EXPERIMENTAL COMPOUND. NO HUMAN CLINICAL TRIALS. Mechanism is potent and irreversible (apoptosis induction). Selective for senescent cells in mouse models but human selectivity profiles are unknown. Aggressive Herxheimer-like inflammatory response from SASP release possible during senescent cell clearance. DO NOT USE without comprehensive medical supervision.

Side EffectIncidenceSeverity
SASP inflammatory responseUnknown in humansmoderate
Unknown off-target apoptosisUnknownrare
