Comparison
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, Selank is a peptide developed in Russia as an anxiolytic and nootropic; in animal models it reduces anxiety-like behavior and modulates immune parameters under stress39.
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, Selank is a synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro, that combines a tuftsin fragment with a Pro-Gly-Pro motif and is reported to modulate GABAergic neurotransmission and cytokine balance while being resistant to proteolytic degradation39.
FOXO4-DRI is amino acids long, whereas Selank is longer as it has a length of 7 amino acids. FOXO4-DRI is made up of a sequence of sequence data not available in the current dataset. Selank is made up of a sequence of Threonine, Lysine, Proline, Arginine, Proline, Glycine, Proline.
FOXO4-DRI
