A new series of 4-[(substituted benzylidene)-3-[(5-(pyridine-4-yl)-1,3,4-oxadiazole-2-ylthio)-methyl]isoxazol-5(4H)-one (6a–g) and 4-(substituted benzylidene)-3-((benzo[d]thiazol-2-ylthio)methyl)isoxazol-5(4H)-one (8a–g) was synthesized. All the synthesized compounds were screened for antitubercular activity against Mycobacterium tuberculosis H37Ra (ATCC 25177) and Mycobacterium bovis BCG (ATCC 35743)
一系列新的4-[(取代的亚苄基)-3-[(5-(吡啶-4-基)-1,3,4-恶二唑-2-基硫基)-甲基]异恶唑-5(4H)-(合成了6a-g)和4-(取代的亚苄基)-3-((苯并[ d ]噻唑-2-基硫基)甲基)异恶唑-5(4 H)- (8a-g)。筛选所有合成的化合物对结核分枝杆菌H37Ra(ATCC 25177)和牛分枝杆菌BCG(ATCC 35743)的抗结核活性,以及对大肠杆菌(NCIM 2576),假单胞菌荧光(NCIM 2059),金黄色葡萄球菌(NCIM 2602)的抗菌活性,枯草芽孢杆菌(NCIM 2162)。在合成的1,3,4-恶二唑和苯并噻唑基硫醚衍生物中,化合物6b和8b显示出优异的抗分枝杆菌活性,化合物6b,8a,8b和8d显示出对所有测试的抗菌菌株均具有优异的抗菌活性。进一步评估了合成的化合物对HCT 116和HeLa癌细胞系的细胞毒活性。1,3,4-恶二唑和苯并
