8-OCH3 ciprofloxacin methylene and ethylene isatin derivatives with remarkable improvement in lipophilicity were synthesized in this study. These derivatives were evaluated for their in vitroactivity against some mycobacteria. All of the synthesized compounds were less active than the parent 8-OCH3 ciprofloxacin against Mycobacteriumsmegmatis CMCC 93202, but most of the methylene isatin derivatives
