Approved drug
trofinetide is an approved drug (FDA (2023))
Compound class: Peptide or derivative
Comment: Trofinetide (NNZ-2566), a synthetic analogue of the amino‐terminal tripeptide of insulin-like growth factor 1 (IGF-1; GPE). It was developed as a neuroprotective agent, for potential application in neurodegenerative diseases of the central nervous system, and traumatic brain injury.
The endogenous glycine-proline-glutamate tripeptide (GPE, Glypromate) is present in the brain [7], and it has been demonstrated to partially reverse core symptoms in Mecp2-deficient mice that are a model of human Rett syndrome [8]. Trofinetide has been modified to offer a longer half-life than GPE.

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.
