derivatives were evaluated for their antimicrobial activities against Gram-positive and Gram-negative bacterial strains using the Agar well diffusion method to study the antimicrobial activities and compared them with the standard drugs. Most compounds displayed moderate activity. Among the tested compounds, the most promising compounds 13 and 15 provided broad bioactive spectrum against Gram-positive and Gram-negative
在本文中,我们报告了一系列新型喹唑啉-2,4(1 H ,3 H )-二酮衍生物的设计和合成,作为细菌旋转酶和 DNA 拓扑异构酶 IV 的氟喹诺酮类抑制剂,以鉴定和开发抗菌药物防止细菌耐药性问题。它们的结构通过光谱分析(IR、NMR 和 EI-MS)得到证实。采用琼脂扩散法研究新型喹唑啉-2,4(1 H ,3 H )-二酮衍生物对革兰氏阳性菌和革兰氏阴性菌的抗菌活性,并与标准品进行比较。药物。大多数化合物显示出中等活性。在测试的化合物中,与标准药物相比,最有前途的化合物13和15提供了针对革兰氏阳性和革兰氏阴性菌株的广泛生物活性谱。
