Nitroimidazoles with antibacterial activity against Neisseria gonorrhoeae

Abstract
Nitroimidazoles were prepared which show interesting activity against the bacterium, N. gonorrhoeae, in addition to the activities usually shown by nitroimidazoles against protozoa and anaerobic bacteria. The compounds were prepared by alkylation of 1-methyl-2-mercaptoimidazole, followed by nitration. Optimum activity occurs with a 5-nitro group and a free carboxyl at the end of the group attached to the S. The linkage between the S atom and the carboxyl group can be alkylene or phenoxyalkylene. These compounds have only weak activity against other aerobic or facultative bacteria.
