GtoPdb Ligand ID: 12332

Synonyms: NA-1 | Tat-NR2B9c
Compound class: Peptide or derivative
Comment: Nerinetide (NA-1) is a peptide that was designed to target the PDZ domain of the PSD-95 protein (gene symbol DLG4) [1] to prevent its interaction with N-methyl-D-aspartate receptors (NMDARs) and neuronal nitric oxide synthase (nNOS) and block assembly of the tri-peptide complex that is a therapeutic target for the treatment of acute ischemic stroke [2-3]. Structurally, nerinetide is a 20 amino acid linear peptide that comprises nine residues derived from the COOH-terminal of the NR2B NMDAR (GluN2B; GRIN2B; that directly interacts with PSD-95's PDZ2 domain) fused to 11 amino acid cell-membrane transduction domain of the HIV-1 Tat protein (Tyr-Gly-Arg-Lys-Lys-Arg-Arg-Gln-Arg-Arg-Arg; to create a cell permeable peptide). The NMDAR/nNOS/PSD-95 complex mediates neurotoxic signaling, and disruption of this function provides a neuroprotective effect that ameliorates ischemic brain damage, without inducing the negative consequences that can arise through NMDAR blockade.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.
