Description

LC553 (SNAP-8)

SNAP-8 | Acetyl Octapeptide-3 | Cosmetic & Peptide Research Compound

LC553 is used as a product code for SNAP-8, also known as Acetyl Octapeptide-3. The compound is a synthetic octapeptide associated with research into SNARE-complex activity, neuronal signaling, peptide–protein interactions, and cosmetic skin-aging pathways. Chemical databases identify LC553 and SNAP-8 as synonyms and list CAS No. 1253115-75-1.

SNAP-8 is designed as a peptide sequence related to the N-terminal region of SNAP-25. Experimental research has examined its ability to interact with components involved in the SNARE complex, a protein system important for vesicle fusion and neurotransmitter release.

Key Characteristics

  • Product Name: LC553
  • Common Name: SNAP-8
  • Chemical Name: Acetyl Octapeptide-3
  • CAS Number: 1253115-75-1
  • Category: Synthetic peptide
  • Primary Research Areas: Peptide chemistry, SNARE-complex research, cellular signaling, and cosmetic formulation research
  • Intended Application: Laboratory, analytical, and formulation research

Research Profile

SNAP-8 is a synthetic peptide designed to model part of the molecular region involved in SNAP-25/SNARE-complex interactions. Research has focused on how peptide interaction with this system can influence vesicle-fusion mechanisms at the cellular level.

The compound is also widely discussed in cosmetic peptide research because of its proposed relationship to mechanisms involved in facial muscle contraction and the appearance of expression-related lines. These cosmetic claims should be distinguished from clinical claims about botulinum toxin, as SNAP-8 does not function in the same way as botulinum neurotoxin.
