New trifluoromethyl quinolone derivatives: Synthesis and investigation of antimicrobial properties

A series of quinolone derivatives, containing different heterocyclic amines were prepared. Synthesized compounds were evaluated for their in vitro antimicrobial activities against two Gram-positive bacteria, three Gram-negative bacteria as well as four fungi. All the derivatives showed good activity towards Gram-positive bacteria and less activity towards Gram-negative bacteria. They also showed moderate to comparable activity against Aspergillus niger and Candida albicans and low to moderate antifungal activity against Aspergillus fumigatus and Aspergillus flavus.
