Common Name(s): R-(methionyl sh-polypeptide-58 decapeptide-40),r-(methionyl sh-polypeptide-58 decapeptide-40), signal peptide,anti-aging bioactive
CAS Number: N/a
DESCRIPTION
What It Does: Stimulates collagen i, iii, iv synthesis and inhibits mmp-1 collagen degradation โ providing clinically measurable wrinkle reduction and skin firmness at ppm concentrations.
Why It's Used: Precision peptide pharmacology: the defined sequence targets specific receptors (tgf-ฮฒ, egf, integrin, achr) with quantifiable binding kinetics enabling mechanism-based efficacy claims.
How It Works: Peptide-receptor binding โ kinase cascade (map kinase, smad, or pi3k-akt) โ col1a1/col3a1 upregulation and mmp-1/mmp-3 downregulation. spps synthesis provides >98% sequence purity for reproducible receptor binding.
Typically Found In: Anti-aging serums,peptide actives
