生物活性

Decapeptide-12, a small oligopeptide, is a tyrosinase inhibitor that interacts with C-terminal residue of tyrosinase (Kd: 61.1 μM). Decapeptide-12 is a competitive inhibitor of mushroom tyrosinase (IC50: 40 μM). Decapeptide-12 also increases transcription of SIRT. Decapeptide-12 reduces melanin content in melanocytes. Decapeptide-12 is used for the research of melanogenesis, senescence, inflammation [1][2][3].

IC50 & Target

IC50: 40 µM (Tyrosinase)[1], Kd: 61.1 μM (Tyrosinase)[2].

体外研究
(In Vitro)

Decapeptide-12 (P4, 0.01-10 mΜ) dose-dependently inhibits mushroom tyrosinase with an IC50 value of 40 μM, and inhibits human tyrosinase by 25-35% at 100 μM[1].
Decapeptide-12 (100 μM, 7 days) leads to 43% reduction in melanin content in melanocytes with no effect on cell proliferation[1].
Decapeptide-12 (peptide P4, 0-400 μM) inhibits the monophenolase reaction with an IC50 value of 123 μM[2].
Decapeptide-12 interact with tyrosinase with a Kd value of 61.1 μM[2].
Decapeptide-12 (100 μM, 72 h) increases transcription of SIRT1, SIRT3, SIRT6, and SIRT7 with reduced cytotoxicity in human neonatal keratinocyte progenitors[3].
Decapeptide-12 (0-1 mM, 72 h) reduces Phytohemagglutinin (PHA)-stimulated PBMC cells proliferation[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
