FOXO4-DRI is a synthetic D-retro-inverso peptide derived from the FOXO4 sequence that engages the p53 binding interface within senescent cells. It is one of the original “senolytic” tool peptides, developed to selectively eliminate senescent cells.
FOXO4-DRI disrupts the FOXO4–p53 interaction in senescent cells, freeing p53 to translocate to mitochondria and trigger apoptosis selectively in cells under senescence-associated stress. Healthy cells lacking this FOXO4–p53 dependency are largely spared in preclinical models.

Reconstitution
Bacteriostatic water (0.9% benzyl alcohol) or sterile water. Add diluent slowly along the vial wall — do not inject directly onto the lyophilized cake. Swirl gently until fully dissolved.
Storage
Lyophilized: −20°C long term; 2–8°C short term (weeks). Protect from light.Reconstituted: 2–8°C, generally up to 14–28 days depending on compound.
Quality
≥99% purity by HPLC. Identity confirmed by mass spectrometry. Independent third-party verification on every lot. COA available per lot.
Handling notes —Avoid repeated freeze–thaw cycles. Do not shake vigorously after reconstitution.
