Quinolones, and derivatives, have also been isolated from natural sources (such as plants, animals and bacteria) and can act as natural antimicrobials and/or signalling molecules. The first quinolone was nalidixic acid-introduced in 1962 for treatment of urinary tract infections in humans.Nalidixic acid was discovered by George Lesher and coworkers in a distillate during an attempt at chloroquine synthesis.luoroquinolones can enter cells easily via porins and, therefore, are often used to treat intracellular pathogens such as Legionella pneumophila and Mycoplasma pneumoniae. For many gram-negative bacteria, DNA gyrase is the target, whereas topoisomerase IV is the target for many gram-positive bacteria.
