A series of 13 new 3-substituted 5-(5-nitro-2-furyl)-1,2,4-oxadiazoles was synthesized from different aminonitriles. All compounds were screened in the disc diffusion test at a 100 μg/mL concentration to determine the bacterial growth inhibition zone presence and diameter, and then the minimum inhibitory concentrations (MICs) were determined for the most active compounds by serial dilution. The compounds
由不同的氨基腈合成了一系列 13 种新的 3-取代 5-(5-硝基-2-呋喃基)-1,2,4-恶二唑。所有化合物均以 100 μg/mL 浓度在纸片扩散测试中进行筛选,以确定细菌生长抑制区的存在和直径,然后通过连续稀释确定最活跃化合物的最低抑菌浓度 (MIC)。这些化合物对 ESKAPE 细菌表现出抗菌活性,主要抑制 5 种细菌的生长。与环丙沙星、呋喃妥因和呋喃嗪相比,一些化合物对 ESKAPE 病原体具有相似或更低的 MIC。特别是,3-氮杂环丁烷-3-基-5-(5-硝基-2-呋喃基)-1,2,4-恶二唑(2h)以低于所有比较物的浓度抑制金黄色葡萄球菌。化合物 2e (5-(5-硝基-2-呋喃基)-3-[4-(吡咯烷-3-基氧基)苯基]-1,2,4-恶二唑)对革兰氏阳性 ESKAPE 病原体以及 M . 结核病。分子外围的差异导致化合物的高选择性。诱导拟合对接(IFD)建模技术被应用于计
