  A series of novel quinazolinone azoles were synthesized and characterized by NMR, IR, MS and HRMS spectra. Bioactive assays showed that some target compounds exhibited significant antimicrobial potency. Especially, nitroimidazole derivative 3a displayed comparable or even superior antibacterial efficacies (MIC = 0.03–0.05 μmol mL−1) in contrast with norfloxacin (MIC = 0.01–0.05 μmol mL−1) and chloromycin
