Nitroxoline is a broad-spectrum antimicrobial and antiprotozoal drug for the treatment of urinary tract infections. Nitroxoline selectively inhibits the synthesis of bacterial DNA, forms complexes with metal-containing microbial cell enzymes and acts as a gram-positive microorganism: Staphylococcus spp. (including S.aureus), Streptococcus spp. (including beta-hemolytic streptococci, Streptococcus pneumoniae, Enterococcus faecalis), Corynebacterium spp., Bacillus subtilis; and gram-negative microorganisms: N.gonorrhoeae, E.coli, Proteus spp., Klebsiella spp., Salmonella spp., Shigella spp., Enterobacter spp.
Nitroxoline is also active against Mycobacterium tuberculosis, Trichomonas vaginalis, some species of fungi (Candida spp., Dermatophytes, molds, some causative agents of deep mycoses).
