GtoPdb Ligand ID: 7248

Synonyms: Axid® | LY-139037
Approved drug
nizatidine is an approved drug (FDA (1988))
Compound class: Synthetic organic
Comment: Nizatidine is a histamine H2 receptor antagonist. It is structurally related to ranitidine but has a thiazole ring substitution in place of the furan ring in ranitidine. Nizatidine was the last new histamine H2 receptor antagonist to be approved prior to proton pump inhibitors reaching the clinic.

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.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the Chemistry Development Kit (CDK) (Willighagen EL et al. Journal of Cheminformatics vol. 9:33. 2017, doi:10.1186/s13321-017-0220-4; https://cdk.github.io/). All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

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.

Summary of Clinical Use Click here for help
Used to treat peptic ulcer disease (PUD) and gastroesophageal reflux disease. in January 2020 Mylan voluntarily recalled prescription nizatidine medications after excess levels of the hepatotoxic and carcinogenic chemical N-nitrosodimethylamine (NDMA) were detected in the capsules. FDA authorisation for all ranitidine medications was withdrawn in April 2020 for the same reason.
