GtoPdb Ligand ID: 7055

Synonyms: Antepsin® | Carafate®
Approved drug
sucralfate is an approved drug (FDA (1981))
Compound class: Synthetic organic
Comment: Sucralfate is a complex of sucrose, sulfate and aluminum which is basic in nature and has an overall negative charge.

Note that this is a complicated chemical complex. Different chemical databases represent this compound in different ways, all of which are valid. The ChEMBL compound is represented by the entry CHEMBL2367706, with separate aluminium hydroxide ions, whereas the structure we show has these ions in association with the sulphites on the core disaccharide sugar. PubChem CID 70789197 also represents the aluminium hydroxide groups in a different way.

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 CDK toolkit. 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.

Bioactivity Comments
This drug attaches non-specifically to proteins in ulcerated tissue (such as albumin and fibrinogen). Acid-induced cross-linking creates a viscous, paste-like material which acts as a protective barrier. This drug therefore has no 'primary' molecular target.
