GtoPdb Ligand ID: 5094

Synonyms: Demser® | DL-alpha-methyltyrosine | metyrosine
Approved drug
methyltyrosine is an approved drug (FDA (1979))
Compound class: Metabolite or derivative
Comment: The INN for this compound is racemetirosine, indicating that it is a racemic mix of its R and S enantiomers. We show the non-isomeric structure to represent this mixture. The website rxlist.com describes the approved drug, Demser, as (-)-α-methyl-L-tyrosine, but shows a non-stereo molecular structure. We have annotated both versions (racemic and S-enantiomer (L or α) with the same US FDA approval date, as the exact compostion of the approved drug is unclear.

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.
