Synthesis, and antimycobacterial and cytotoxic evaluation of certain fluoroquinolone derivatives

Certain 1-ethyl- and 1-aryl-6-fluoro-1,4-dihydroquinol-4-one derivatives were synthesized and evaluated for antimycobacterial and cytotoxic activities. Preliminary results indicated that, for 1-aryl-6-fluoroquinolones, both 7-(piperazin-1-yl)- and 7-(4-me
