title: Synthesis and evaluation for biological activity of 3-alkyl and 3-halogenoalkyl-quinoxalin-2-ones variously substituted. Part 4.
abstract: A new series of 3-isopropyl-, 3-trifluoromethyl- and 3-bromomethylquinoxaline-2-ones variously substituted on the benzo-moiety were synthesized and submitted to a preliminary in vitro evaluation for antibacterial, antifungal and anti-HIV activities. Furthermore, all compounds were also tested for cytotoxicity. Results of the screening showed that compound 10 exhibits moderate antimicrobial activity against Staphylococcus aureus (MIC = 33 microM), and that 25 and 26 showed interesting cytotoxicity versus mock-infected MT-4 cells. All the other compounds were inactive.
