FOXO4-DRI is a groundbreaking D-amino acid retro-inverso peptide developed by Peter de Keizer’s group at Erasmus MC. It selectively disrupts the FOXO4-p53 interaction that protects senescent cells from apoptosis, inducing their targeted clearance while sparing healthy cells. First published in 2017, it demonstrated dramatic lifespan extension and tissue rejuvenation in progeroid and naturally aged mice. This research-grade lyophilized peptide is synthesized under strict quality controls and provided with full analytical documentation, making it the gold-standard tool for senolytics, longevity, and age-related disease research.
