A series of novel quinolin-2(1H)-one derivatives were synthesized and characterized by IR, 1H NMR, 13C NMR, and MS spectral data. All the new compounds were screened for their antimicrobial activities against six trains of bacteria and five fungi in vitro by twofold serial dilution technique. The bioactive assay showed that most of the compounds exhibited(More)
A series of novel 1-methyl-3-substituted quinazoline-2,4-dione derivatives was designed, synthesized, and evaluated for their antimicrobial activities against six strains of bacteria and five fungi in vitro. The synthesized compounds were characterized by spectral methods. The bioactive assays showed that most of the compounds exhibited moderate(More)
