obtained compounds were screened for antibacterial activity against Staphylococcus aureus (ATCC 25923), Staphylococcus epidermidis (ATCC 12228), Enterococcus faecalis (ATCC 29212), Escherichia coli (ATCC 25922), and Pseudomonas aeruginosa (ATCC 27853). Their antibacterial activity against gram-positive bacteria was higher than against gram-negative bacteria, and derivatives containing electron-withdrawing
由二硫化碳,水合肼和乙酸分三步合成了4-氨基-5-甲基-2,4-二氢-3 H -1,2,4-三唑-3-硫酮。其与由取代的苯甲酰氯制备的苯甲酰基异硫氰酸酯和硫氰酸铵反应,得到相应的N-苯甲酰基-N'-三唑基-硫脲。筛选获得的化合物对金黄色葡萄球菌(ATCC 25923),表皮葡萄球菌(ATCC 12228),粪肠球菌(ATCC 29212),大肠杆菌(ATCC 25922)和铜绿假单胞菌的抗菌活性(ATCC 27853)。它们对革兰氏阳性细菌的抗菌活性高于对革兰氏阴性细菌的抗菌活性,并且含有吸电子基团的衍生物比具有供电子取代基的衍生物更具活性。
