Placement of alkyl substituents on the C-7 piperazine ring of fluoroquinolones: dramatic differential effects on mammalian topoisomerase II and DNA gyrase.
Several substituted analogs of 7-(cis-3,5-dimethylpiperazinyl)-6,8-difluoro-5-amino-1-cyclopropyl quinolone were prepared and tested in a DNA cleavage assay with calf thymus topoisomerase II. Positioning of the methyl groups on the C-7 piperazine ring influenced potency against the mammalian enzyme;...
