[Synthesis and antibacterial activity of pyridonecarboxylic acid derivatives containing 2-methyl-5-nitroimidazol].


PMID 12889123

Abstract

To study the synthesis and antibacterial activity of pyridonecarboxylic acid derivatives containing 2-methyl-5-nitroimidazol. Pyridonecarboxylic acid derivatives containing 2-methyl-5-nitroimidazol were synthesized primarily from 2-methyl-5-nitroimidazol, norfloxacin, ciprofloxacin, enoxacin via nucleophilic substitution and esterification. The antibacterial activity of the nine target compounds were tested. Nine new compounds were synthesized (IIa-c and IIIa-f). The structure of the title compounds were identified by 1HNMR, MS as well as elementary analysis. Compounds IIa, IIb and IIc showed antibacterial activity, and were worth further studying.
