| Biological Activity | This peptide is the C‑terminal fragment (residues 18‑36) of human Neuropeptide Y. It retains binding affinity for NPY receptors, with reported activity primarily at the Y₂ subtype, and is commonly used as a tool to study Y₂‑mediated functions such as presynaptic inhibition and feeding behavior. Activity should be validated in Y₂ receptor binding or functional assays. |
| Storage Conditions | Lyophilized powder: Store desiccated at –20 °C or below, protected from light, for long‑term stability. Reconstituted solution: Aliquot and store at ≤ –20 °C; avoid repeated freeze‑thaw cycles. |
| Stock Location | Stock in USA |
| MOQ | 1g |
1.MECHANISM OF ACTION
Neuropeptide Y (18-36) functions as a Y₂ receptor-preferring agonist, binding to NPY Y₂ receptors and coupling to Gi/o proteins to inhibit adenylate cyclase and reduce intracellular cAMP levels. This signaling cascade activates inwardly rectifying potassium channels and inhibits voltage-gated calcium channels, leading to presynaptic inhibition of neurotransmitter release (e.g., glutamate, GABA). The resulting hyperpolarization and reduced neuronal excitability modulate synaptic transmission, contributing to effects on feeding behavior, anxiety-like responses, and autonomic nervous system regulation, making it a selective probe for Y₂ receptor-specific pathways.
2.PRODUCT INDICATIONS
This human NPY fragment is indicated exclusively for research applications focused on Y₂ receptor pharmacology and truncated NPY fragment studies. It is employed in Y₂-selective receptor binding and competition assays, functional studies of presynaptic inhibition and neurotransmitter release, appetite and feeding behavior research with emphasis on Y₂-mediated effects, anxiety and stress response models, and autonomic function investigations. The product serves as a reference ligand for validating Y₂ receptor expression, screening Y₂-selective compounds, and comparing the activity of different NPY C-terminal fragments in obesity, anxiety, and cardiovascular research. It is not intended for diagnostic, therapeutic, or clinical use.
3.CLINICAL EFFICACY OF PRODUCT
As a research reagent, Neuropeptide Y (18-36), human has no established clinical efficacy or safety profile for therapeutic applications. The peptide has not undergone clinical trials, regulatory approval, or safety evaluation for any medical indication. While it contributes to fundamental understanding of Y₂ receptor biology and may inform the development of future therapeutic agents targeting Y₂ receptors for obesity, anxiety, or autonomic disorders, its utility remains confined to preclinical research. Any clinical translation would require development of entirely distinct therapeutic agents with comprehensive preclinical and clinical testing.
