1-(Ethyl-d5)-1,4-dihydro-7-methyl-4-oxo-1,8-naphthyridine-3-carboxylic Acid;|1,4-Dihydro-1-(ethyl-d5)-7-methyl-4-oxo-1,8-naphthyridine-3-carboxylic Acid; Betaxina-d5; Cybis-d5; Dixiben-d5; Eucistin-d5; NegGram-d5; Nelidix-d5; Win 18320-d5; Wintomylon-d5;

Inhibitor of bacterial DNA synthesis. Nalidixic acid is the first of the synthetic quinolone antibiotics. It is a naphthyridone, not a quinolone: its ring structure is a 1,8-naphthyridine nucleus that contains two nitrogen atoms, unlike quinoline, which has a single nitrogen atom.[1] Synthetic quinolone antibiotics were discovered by George Lesher and coworkers as a byproduct of chloroquine manufacture in the 1960s.[1] Used clinically from 1967.[1]

Nalidixic acid is effective against both gram-positive and gram-negative bacteria. In lower concentrations, it acts in a bacteriostatic manner; that is, it inhibits growth and reproduction. In higher concentrations, it is bactericidal, meaning that it kills bacteria instead of merely inhibiting their growth.
