Two series of new 2,3-dihydrooxazole-spirooxindole derivatives were efficiently synthesized starting from N′-(2-oxoindolin-3-ylidene) benzohydrazide/N′-(2-oxoindolin-3-ylidene)-2-phenoxyacetohydrazide using designed synthetic route. Newly synthesized 2,3-dihydrooxazole-spirooxindole derivatives were screened for their antibacterial and antifungal activity against different pathogenic strain of bacteria
使用设计的合成方法,从N '-(2-氧代吲哚-3-亚基)苯甲酰肼/ N '-(2-氧代吲哚-3-亚基)-2-苯氧基乙酰肼开始有效合成了两个系列的新的2,3-二氢恶唑-螺氧并恶唑衍生物。路线。筛选了新合成的2,3-二氢恶唑-螺氧并恶唑衍生物对不同病原菌的细菌和真菌的抗菌和抗真菌活性。确定了测试化合物和参考标准品的最小抑菌浓度(MIC),最小杀菌浓度(MBC)和最小杀菌浓度(MFC)。化合物4e,4g,7g表现出良好的抗菌活性,而化合物4f,7b,7d显示出更好的抗真菌活性。
