Synthesis and antibacterial activity of some 3-[(alkylthio)methyl]quinoxaline 1-oxide derivatives.
Some 3-[(alkylthio)methyl]quinoxaline 1-oxide derivatives (1) have been synthesized and screened for antibacterial activity. 2-Acetyl-3-[(methylsulfonyl)methyl]quinoxaline 1-oxide (7a) was found to possess good in vitro activity against some pathogens important to veterinary medicine including Treponema hyodysenteriae, a causative agent in swine dysentery. In an in vivo experiment, this compound (7a) completely protected pigs against a swine dysentery challenge over a 21-day period.
