Synonyms: Gantanol® | RO 4-2130 | RO-42130 | SMX | STX-608
Approved drug PDB Ligand
sulfamethoxazole is an approved drug (FDA (1965))
Compound class: Synthetic organic
Comment: Sulfamethoxazole is a sulfonamide antibacterial that has bacteriostatic activity. It inhibits the bacterial dihydropteroate synthase pathway which generates the folic acid that is essential for bacterial growth. It is active against Gram-negative and Gram-positive bacteria including Listeria monocytogenes and E. coli.

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
Sulfamethoxazole is used to treat bacterial urinary tract infections, bronchitis, and prostatitis. It is principally used in combination with trimethoprim (SMX-TMP, Co-Trimoxazole). Co-Trimoxazole is authorised for use in the UK. SMX-TMP is on the WHO Model List of Essential medicines as a first-line medicine for urinary tract infections.
