以苯并异噻唑-3-酮为原料合成了4种新型衍生物——3-氯丙酰氯-苯并异噻唑啉酮、丙酰氯-苯并异噻唑啉酮、丙烯酰氯-苯并异噻唑啉酮、甲基丙烯酰氯-苯并异噻唑啉酮;目标化合物的结构经过1HNMR和质谱(MS)分析确认。同时检测这4种化合物对几种常见微生物——大肠杆菌(Escherichia coli)、枯草芽孢杆菌(Bacillus subtilis)和金黄色葡萄球菌(Staphyloccus aurueus)的抗菌活性。结果表明;这4种化合物在较低浓度下(≤25 mg/L)对大肠杆菌和枯草芽孢杆菌的抑菌率均达到80%以上;而对金黄色葡萄球菌的抑菌效果较差;只有高浓度(≥50 mg/L)下才能明显抑制其生长
