- Developing ciprofloxacin analogues against plant DNA gyrase: A novel herbicide mode of action
-
Ciprofloxacin has been shown to exhibit potent herbicidal activity through action against plant DNA gyrase, presenting a novel mode of action. Analogues of ciprofloxacin have been prepared with increased herbicidal activity and diminished antibacterial activity, compared to ciprofloxacin, as demonstrated using model systems.

- Structure-Activity Relationships of Antibacterial 6,7- and 7,8-Disubstituted 1-Alkyl-1,4-dihydro-4-oxoquinoline-3-carboxylic Acids
-
Previous quantitative and qualitative structure-activity studies in antibacterial monosubstituted 1-ethyl-1,4-dihydro-4-oxoquinoline-3-carboxylic acids prompted us to synthesize the 6,7,8-polysubstituted compounds.In this paper, the preparation and antibacterial activity of the 6,7- and 7,8-disubstituted compounds and their derivatives are described.Among these compounds, 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)quinoline-3-carboxylic acid (34) possessed many significant activities and was more active than oxolinic acid (84) against Gram-positive andGram-negative bacteria.Structure activity relationships are discussed.
