Understanding APGWamide: The Conserved Molluscan Neuropeptide

APGWamide (Ala-Pro-Gly-Trp-NH₂) is a tetrapeptide that was first purified from the ganglia of the African giant snail (Achatina fulica) . Despite its small size, this peptide plays significant roles in nervous system function and reproductive development across multiple species.

Key Characteristics

• Sequence: H-Ala-Pro-Gly-Trp-NH₂ (APGW-NH₂)

• Molecular Formula: C₂₁H₂₈N₆O₄

• Molecular Weight: 428.48 g/mol

• CAS Number: 126675-52-3

• Structure: Synthetic tetrapeptide with C-terminal amidation

Biological Activity

Research has demonstrated that APGWamide functions as an inhibitory neurotransmitter in molluscan neurons . It produces hyperpolarization of neurons through increased membrane permeability to potassium ions (K⁺), resulting in outward current and reduced neuronal excitability . The peptide has an ED₅₀ of approximately 6.2 × 10⁻⁶ M in neuronal assays .
