Two coumarins, inhibitors of the B subunit of DNA gyrase, and six quinolones, inhibitors of the A subunit, were tested against Escherichia coli topoisomerase I-catalyzed DNA relaxation. Coumarins had no effect, whereas quinolones were inhibitors of the enzyme. This inhibition was compared with that of DNA gyrase and calf thymus topoisomerase I. The 50% inhibitory concentrations for E. coli topoisomerase I were about one order of magnitude higher than the corresponding values for E. coli DNA gyrase but were far lower than the known values for calf thymus topoisomerase I. There was a good relationship between inhibition of the two prokaryotic topoisomerases and MICs for E. coli, and the quinolones could be ranked in the same order in the three cases.

D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
