GtoPdb Ligand ID: 12316

Synonyms: Ac-Ala-Val-Ome
Compound class: Peptide
Comment: ZZL-7 is a novel di-peptide with rapid-onset anti-depressant activity in in vivo models [1]. It binds to the PDZ domain of neuronal NOS (nNOS) and blocks its interaction with the serotonin (5-HT) transporter (SERT; SLC6A4) in the dorsal raphe nucleus (DRN). This mechanism increases SERT translocation the cell surface, in turn increasing 5-HT transport out of the cell and into the intracellular space, with a resulting increase in firing of serotonergic neurons. ZZL-7 has been shown to readily cross the blood-brain barrier in mice following intravenous injection.

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.
