Quinoxalin-2-ones. Part 5. Synthesis and antimicrobial evaluation of 3-alkyl-, 3-halomethyl- and 3-carboxyethylquinoxaline-2-ones variously substituted on the benzo-moiety.
A new series of 3-alkyl-, 3-trifluoromethyl-, 3-carboxyethyl- and 3-bromomethylquinoxaline-2-ones and 2,3-bis(bromomethyl)quinoxalines bearing Cl, CF3, morpholine on the benzo-moiety, were synthesised and submitted to a preliminary in vitro evaluation for antibacterial and anticandida activities. Results of the screening showed that compounds 9b, 14b and 19b (MIC=62.5 microg/ml) and 10b (MIC=15.6 microg/ml) were the most active against Vibrio alginolyticus.
