FOXO4-DRI 99%+ High Purity Cosmetic Raw Material 2460055-10-9

FOXO4-DRI (Forkhead Box O4 D‑Retro‑Inverso) is a synthetic peptide constructed entirely from D‑amino acids in a reversed sequence order relative to the native L‑isoform. Its molecular formula is C₂₂₈H₃₈₈N₈₆O₆₄, and its molecular weight is approximately 5358.06 g/mol. The D‑retro‑inverso configuration replaces each L‑amino acid with its D‑isomer counterpart while reversing the direction of the peptide chain. This architectural modification is employed in formulation research to evaluate how D‑amino acid substitution influences peptide stability, solubility, and interaction characteristics in topical vehicles.

In cosmetic formulation research, FOXO4-DRI is of interest for its unique D‑amino acid composition and high water solubility. As a research‑grade cosmetic raw material, it provides a well‑characterized model for studying the behavior of D‑configured peptides in water‑based formulation systems.
