All compounds were active against <em>Staphylococcus aureus</em> (MIC=3.12-6.12µg/mL) and compounds 1a, 1c-e, 2a, and 3c(MIC=3.12µg/mL) exhibited excellent antibacterial activity in comparison to ciprofloxacin and norfloxacin (MIC=6.25µg/mL). Fluoroquinolone derivatives exhibited good activity against food borne bacteria and are appropriate candidates for food poisoning prevention. https://jsciences.ut.ac.ir/article_57001_0459e51e7ef6c2f71de6e26dce86cf22.pdf
