Oxo quinoline derivatives

A quinoline derivative of the formula STR1 wherein Z is an amino group or a halogen atom, and R1, R2 and R3 are the same or different and each represents a hydrogen atom or a lower alkyl group having 1 to 5 carbon atoms, and an ester thereof and a salt of the derivative or the ester and processes for preparation thereof. These compounds show excellent antibacterial activity and are useful as antibacterial agents.

Synthesis and Structure-Activity Relationships of 5-Substituted 6,8-Difluoroquinolones, Including Sparfloxacin, a New Quinolone Antibacterial Agent with Improved Potency

A series of 5,7-disubstituted 1-cyclopropyl-6,8-difluoro-4(1H)-oxoquinoline-3-carboxylic acids (10-36) were prepared; the C-5 substituent in these compounds comprised halo, hydroxy, mercapto, and amino groups and the C-7 functional group included variously substituted piperazines.In vitro antibacterial screening results indicated that the amino group was optimal among the C-5 substituents.A combination of the C-5 amino group and the C-7 3,5-dimethylpiperazinyl appendage in this series conferred the best overall antibacterial property with lack of adverse drug interactions.Compound 36k was superior to ciprofloxacin in both in vitro and in vivo potency and hence was selected as a promising candidate for an improved therapeutic agent.
