Acetilhexapéptido-1

Synonyms: Ac-Tyr-Arg-OH, N-Acetyl-L-tyrosyl-L-arginine, Acetyl Dipeptide-2, N-Acetyl-Tyrosyl-Arginine, Ac-Di peptide-2

Acetyl Hexapeptide-1 is a synthetic dipeptide composed of N-acetylated L-tyrosine and L-arginine. The acetylation of the N-terminus enhances its enzymatic stability, while the guanidinium group of arginine provides a positive charge at physiological pH, facilitating interaction with negatively charged cell membranes and contributing to its biological activity.

As a member of the peptide family, Acetyl Hexapeptide-1 is primarily used in cosmetic formulations aimed at skin conditioning and anti-aging. Its small molecular size allows for good skin penetration, and it functions as a signaling peptide to support collagen synthesis and improve skin elasticity. In research settings, it serves as a model compound for studying peptide-membrane interactions and the role of dipeptides in cellular processes.

Mecanismo de acción

• Collagen synthesis: Stimulates fibroblasts to produce type I collagen, improving skin firmness.
• Defensa antioxidante: The tyrosyl moiety can scavenge free radicals, reducing oxidative stress in skin cells.
• Membrane interaction: The cationic arginine residue binds to anionic phospholipids in cell membranes, enhancing cellular uptake.
• Transducción de señales: Modulates matrix metalloproteinase (MMP) activity, reducing collagen breakdown.
