A series of 23 new 2‐[p‐substituted‐benzyl]‐5‐[p‐substituted‐phenyl/benzyl‐carbonylamino]benzoxazole derivatives has been synthesized by reacting 5‐amino‐2‐[p‐substituted‐benzyl]benzoxazoles with the appropriate carboxylic acid chlorides. The structures of the synthesized compounds were confirmed by IR and 1H‐NMR spectral data. Antimicrobial activities of the compounds were investigated using the twofold
通过5-氨基-2-[p-取代-苄基]苯并恶唑与2-[p-取代-苄基]-5-[p-取代-苯基/苄基-羰基氨基]苯并恶唑反应合成了23种新的2-[p-取代-苄基]-5-[p-取代-苯基/苄基-羰基氨基]苯并恶唑衍生物。适当的羧酸氯化物。合成化合物的结构由IR和1H-NMR光谱数据证实。与标准药物相比,使用双重连续稀释技术对两种革兰氏阳性菌和两种革兰氏阴性菌以及三种念珠菌属物种的抗菌活性进行了研究。微生物学结果表明,新合成的2-[p-取代-苄基]-5-[p-取代-苯基/苄基-羰基氨基]苯并恶唑衍生物(3-25)具有广谱活性,显示MIC值为6.25- 200 μg/mL 针对革兰氏阳性和革兰氏阴性微生物进行测试。此外,它们对所测试的念珠菌种类显示出显着的抗真菌活性,MIC 值为 3.12-100 μg/mL。特别是,2-苄基-5-[对溴苄基-羰基氨基]苯并恶唑 9 的 MIC 值为 3.12 μg
