SNAP-8 Peptide

🧪 What Is SNAP-8 Peptide? The Verified Molecular Identity

SNAP-8 (Acetyl Octapeptide-3; CAS 868844-74-0) is a synthetic octapeptide engineered as a competitive inhibitor of the SNARE complex—the conserved ternary protein machinery responsible for vesicle docking and neurotransmitter exocytosis at the neuromuscular junction .

THIS IS THE CORRECT MOLECULAR ENTITY FOR SNARE COMPLEX INHIBITION RESEARCH.

Molecular Definition:

Why SNAP-8 Is Scientifically Distinct:

SNAP-8 represents the engineered evolution of neurotransmitter-inhibiting peptide technology :

The Structural Rationale:

The addition of C-terminal Alanine-Aspartic acid (Ala-Asp) extends the SNAP-25 mimetic domain, potentially providing additional binding contacts with Syntaxin and VAMP within the SNARE complex assembly site . This elongation enhances competitive displacement of native SNAP-25 without increasing cytotoxicity .

What SNAP-8 IS (Verified):

• ✅ A synthetic octapeptide mimic of the N-terminal domain of SNAP-25
• ✅ A competitive inhibitor of SNARE complex assembly
• ✅ A neurotransmitter release modulator (acetylcholine)
• ✅ A non-invasive, non-neurotoxic research tool for neuromuscular junction studies
• ✅ A 30% more potent analog compared to first-generation hexapeptides

What SNAP-8 IS NOT:

• ❌ NOT Botulinum toxin (does NOT enzymatically cleave SNARE proteins)
• ❌ NOT a muscle relaxant (does NOT block postsynaptic acetylcholine receptors)
• ❌ NOT interchangeable with Argireline (different sequence, different efficacy profile)
• ❌ NOT a collagen-stimulating matrix peptide
• ❌ NOT a copper-binding peptide

⚠️ STRICT RESEARCH USE ONLY: Not for human consumption, injection, topical application, or cosmetic formulation. For in vitro and ex vivo laboratory experimentation exclusively.

🔬 How Does SNAP-8 Work? The SNARE Complex Inhibition Mechanism

SNAP-8 operates via a competitive inhibition mechanism targeting the SNARE (Soluble N-ethylmaleimide-sensitive factor Attachment Protein Receptor) complex—the conserved molecular machinery responsible for vesicle docking and neurotransmitter exocytosis .

1. 🧲 Molecular Mimicry: The SNAP-25 N-Terminal Domain

SNAP-8 is rationally engineered to precisely mimic the N-terminal domain of SNAP-25 (Synaptosomal-Associated Protein of 25 kDa) —a critical t-SNARE protein localized to the presynaptic plasma membrane .

The Native SNARE Complex:

• Proteins Involved: VAMP (vesicle-associated membrane protein; on vesicle membrane), Syntaxin (on target membrane), and SNAP-25 (on target membrane)
• Assembly: These three proteins coil into a stable four-helix bundle that physically pulls the vesicle and plasma membranes together
• Outcome: Membrane fusion → neurotransmitter (acetylcholine) release into synaptic cleft → muscle contraction

2. ⚡ Competitive Inhibition: Displacement of Native SNAP-25

SNAP-8 functions as a competitive antagonist :

1. Recognition: The octapeptide sequence is recognized by Syntaxin and VAMP as a legitimate binding partner
2. Occupation: SNAP-8 occupies the spatial position and binding sites normally filled by native SNAP-25
3. Destabilization: The truncated peptide cannot fully stabilize the four-helix bundle, resulting in a partially formed, dysfunctional SNARE complex
4. Functional Consequence: Reduced vesicle fusion efficiency → attenuated acetylcholine release → decreased muscle contraction amplitude

📌 Critical Mechanistic Distinction:

3. 🧪 Quantitative Efficacy: 30% Enhancement Over Hexapeptide

Peer-reviewed comparisons demonstrate:

"SNAP-8 was developed as an elongation of Argireline, with the addition of two amino acids. This structural modification was investigated for its potential to increase the peptide's ability to disrupt the SNARE complex… some research suggesting that SNAP-8 may be approximately 30% more active than its parent peptide."

Clinical Documentation:

• Wrinkle depth reduction: Up to 63.13% in clinical studies
• Time course: Significant reduction observed at 28–30 days
• Dose-response: Formulations containing 3–10% SNAP-8 demonstrate efficacy

4. 🧬 Molecular Architecture & Stability Features

N-Terminal Acetylation:

• Neutralizes positive charge at N-terminus
• Enhances proteolytic resistance to aminopeptidases
• Mimics native protein conformation

C-Terminal Amidation:

• Removes negative charge at C-terminus
• Increases membrane penetration potential
• Extends experimental half-life

Methionine Residue:

• Oxidation-sensitive (Met → Met sulfoxide)
• Requires nitrogen-purged storage and reducing conditions for long-term stability

❓ Frequently Asked Questions (FAQs)

1. Is SNAP-8 the same as Argireline (Acetyl Hexapeptide-3)?

NO. THIS IS A CRITICAL DISTINCTION. 🚫

SNAP-8 IS THE ENGINEERED ELONGATION OF ARGIRELINE. The addition of Ala-Asp confers enhanced competitive inhibition. They are NOT interchangeable.

2. Is SNAP-8 the same as Botox?

NO. FUNDAMENTALLY DIFFERENT MECHANISMS.

SNAP-8 DOES NOT CLEAVE OR DEGRADE SNAP-25. It reversibly competes for binding sites. It is non-neurotoxic, non-paralytic, and fully reversible .

3. What purity do I need for SNARE complex binding assays?

≥98% IS MANDATORY FOR PUBLICATION-QUALITY DATA.

Lower-purity batches (95–97%) from non-verified sources consistently contain:

• Oxidized methionine (Met(O)) → altered conformation → reduced binding affinity
• Deletion sequences → competitive inhibition heterogeneity → confounded EC₅₀
• Truncated fragments → partial agonist activity → unreproducible data

Our ≥98% specification with documented oxidation control ensures you are testing the INTENDED molecular entity.

4. How do I reconstitute SNAP-8?

EXCELLENT AQUEOUS SOLUBILITY. Unlike acylated lipopeptides, SNAP-8 is hydrophilic and freely soluble in aqueous buffers.

Reconstitution protocol:

1. Centrifuge vial briefly (5,000 × g, 10 sec) to ensure pellet at bottom.
2. Add sterile HPLC-grade water, PBS (pH 7.4), or cell culture media (10 mg/mL).
3. Vortex gently 30–60 seconds until optically clear.
4. Aliquot immediately into single-use vials.
5. Store at -80°C for long-term stability (>6 months).
6. AVOID freeze-thaw cycles. Discard unused working solution.

LC-MS/MS diluent: HPLC-grade water containing 0.1% formic acid .

5. How stable is reconstituted SNAP-8?

• Lyophilized powder: 24 months at -20°C (desiccated, light-protected, nitrogen-purged)
• In water/PBS (frozen): 6 months at -80°C; 1 month at -20°C (single-use aliquots)
• In water/PBS (4°C): <7 days (risk of bacterial growth; peptide stable but solution not sterile)
• At room temperature: <24 hours
• Critical: Methionine oxidation accelerates in solution. Minimize oxygen exposure. Use reducing agents (DTT, TCEP) if compatible with assay.

6. What is the documented wrinkle reduction percentage?

UP TO 63.13% in clinical studies .

"One study noted a maximal reduction in wrinkle depth of up to 63.13% in subjects."
