Nalidixic Acid_[M+H]+ (BioDeep_00000001809)1-Ethyl-7-methyl-4-oxo-1,4-dihydro-[1,8]naphthyridine-3-carboxylic acid
Formula: C12H12N2O3 (232.0847882)
SMILES:
CCN(C=1)c(n2)c(ccc(C)2)C(=O)C(C(O)=O)1
Nalidixic Acid is only found in individuals that have used or taken this drug. It is a synthetic 1,8-naphthyridine antimicrobial agent with a limited bacteriocidal spectrum. It is an inhibitor of the A subunit of bacterial DNA gyrase. [PubChem]Evidence exists for Nalidixic acid that its active metabolite, hydroxynalidixic acid, binds strongly, but reversibly, to DNA, interfering with synthesis of RNA and, consequently, with protein synthesis.

Nalidixic acid acts in a bacteriostatic manner in lower concentrations and is bactericidal in higher concentrations. Nalidixic acid inhibits a subunit of DNA gyrase and topoisomerase IV and reversibly blocks DNA replication in susceptible bacteria[1].
