A series of 6-methylpyrimidin-4(3H)-one and oxo-1,2,4-triazolo[4,3-a]pyrimidine derivatives (1-18) was designed to meet the urgent need for novel antibacterial and antioxidant agents. The in vitro antibacterial activity revealed that most of the compounds exhibited a good inhibitory effect on Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria with MIC values in the
设计了一系列 6-methylpyrimidin-4( 3H )-one 和 oxo-1,2,4-triazolo[4,3-a]pyrimidine 衍生物 ( 1-18)以满足对新型抗菌和抗氧化剂的迫切需求. 的体外抗菌活性表明,大多数化合物显示出对革兰阴性(良好的抑制效果的大肠杆菌)和革兰氏阳性(金黄色葡萄球菌)以MIC值细菌55-200微克/毫升为范围大肠杆菌金黄色葡萄球菌为 125–700 µg/mL 。(E)-2-(2-(4-甲氧基亚苄基)肼基)-6-methylpyrimidin-4(3H)-one ( 8 ) 是最活跃的化合物(MIC = 55 和 125 µg/mL 对大肠杆菌)和金黄色葡萄球菌)。所有化合物都表现出从弱到中到高的抗氧化活性。将所得到的结果显示,化合物3,5,6,9,16,和18具有的所有化合物中的优越性,展示出最高容量耗尽DPPH(1 , 1 -二苯基- 2
