Nalidixic Acid and the Metabolism of Escherichia coli.

Journal of bacteriology

Winshell EB, Rosenkranz HS.
PMID: 16559090
J Bacteriol. 1970 Dec;104(3):1168-75. doi: 10.1128/jb.104.3.1168-1175.1970.

Nalidixic acid (NAL) is bactericidal for E. coli B. Synthesis of deoxyribonucleic acid (DNA), ribonucleic acid and protein was necessary to initiate the lethal effect, but only protein synthesis was necessary to sustain it. NAL inhibited DNA synthesis specifically,...

Light-induced Enzyme Formation in a Chlorophyll-less Mutant of Euglena gracilis.

Plant physiology

Russell GK, Draffan AG.
PMID: 16660582
Plant Physiol. 1978 Nov;62(5):678-82. doi: 10.1104/pp.62.5.678.

A mutant strain, Y(9), of Euglena gracilis strain Z that is unable to produce protochlorophyll or chlorophyll has been isolated following treatment of wild type cells with nalidixic acid. Dark-grown cells of the mutant contain proplastids that show only...

Physicochemical Studies and Anticancer Potency of Ruthenium η-p-Cymene Complexes Containing Antibacterial Quinolones.

Organometallics

Kljun J, Bytzek AK, Kandioller W, Bartel C, Jakupec MA, Hartinger CG, Keppler BK, Turel I.

Organometallics. 2011 May 09;30(9):2506-2512. doi: 10.1021/om101180c. Epub 2011 Apr 06.

With the aim of exploring the anticancer properties of organometallic compounds with bioactive ligands, Ru(arene) compounds of the antibacterial quinolones nalidixic acid (2) and cinoxacin (3) were synthesized, and their physicochemical properties were compared to those of chlorido(η(6)-p-cymene)(ofloxacinato-κ(2)O,O)ruthenium(II) (1)....

A 9-year study of shigellosis in Northeast Malaysia: Antimicrobial susceptibility and shifting species dominance.

Zeitschrift fur Gesundheitswissenschaften = Journal of public health

Banga Singh KK, Ojha SC, Deris ZZ, Rahman RA.

Nalidixic acid (NA) and its main metabolite, 7-hydroximethylnalidixic acid (OHNA), are quinolones antibacterial used as agents used for the treatment of urinary tract infection. For both compounds an adsorption process on a hanging mercury electrode (HMDE). On this basis,...

Effect of enrofloxacin administration on excretion of Salmonella ententidis by experimentally infected chickens and on quinolone resistance of their Escherichia coli flora.

Avian pathology : journal of the W.V.P.A

Barrow PA, Lovell MA, Szmolleny G, Murphy CK.
PMID: 18484047

Chickens which had been experimentally-infected with a strain of Salmonella ententidis and treated by administration of enrofloxacin at commercially recommended concentrations in the drinking water, virtually eliminated this organism from the alimentary tract. However, an initially quinolone-sensitive Escherichia coli...
