Description

Amino Acid Sequence

Ac-Glu-Glu-Met-Gln-Arg-Arg-NH2

Biochem/physiol Actions

Ac-EEMQRR-NH2 is a SNAP25 N-terminal-derived peptide that inhibits the SNARE complex and possibly blocks neuronal exocytosis. Ac-EEMQRR-NH2 exhibits anti-inflammatory and anti-wrinkle activity. It is used as anti-wrinkle cosmetics ingredient.

Ac-EEMQRR-NH2 trifluoroacetate salt is considered 4000 times less toxic than botulin toxin. It has restricted transdermal penetration and hence has limited application for topical usage.
