The reaction of 7-chloro-1-methylpyridazino[3,4-b]quinoxalin-4(1H)-ones 3a-5a with sodium methylthiolate gave 1-methyl-7-methylsulfanylpyridazino[3,4-b]quinoxalin-4(1H)-ones 8a-c, whose reaction with m-chloroperbenzoic acid afforded the 7-methanesulfonyl-1-methylpyridazino[3,4-b]-quinoxalin-4(1H)-ones 9a-c, respectively. The above substituent change at the 7-position resulted in the activity alteration
7-氯-1-甲基吡啶并[3,4- b ]喹喔啉-4(1 H)-ones 3a-5a与甲基硫代硫酸钠反应,得到1-甲基-7-甲基硫烷基吡啶并[3,4- b ]喹喔啉-4 (1 ħ) -酮8A-C ,其与反应米氯过苯甲酸的7-甲磺酰基-1-甲基哒嗪并[3,4-得到b ] -喹喔啉-4(1 ħ) -酮9A-C分别。上述取代基在7位上的改变导致对微生物的活性改变。
