To develop new antimicrobial agents, a series of novel thiourea derivatives incorporated with different moieties 2–13 was designed and synthesized and their biological activities were evaluated. Compounds 7a, 7b and 8 exhibited excellent antimicrobial activity against all Gram-positive and Gram-negative bacteria, and the fungal Aspergillus flavus with minimum inhibitory concentration (MIC) values ranged
为了开发新的抗菌剂,设计并合成了一系列与不同部分 2-13 结合的新型硫脲衍生物,并评估了它们的生物活性。化合物 7a、7b 和 8 对所有革兰氏阳性菌和革兰氏阴性菌均表现出优异的抗菌活性,真菌黄曲霉的最小抑菌浓度 (MIC) 范围为 0.95 ± 0.22 至 3.25 ± 1.00 μg/mL。此外,针对 MCF-7 细胞的细胞毒性研究表明,化合物 7a 和 7b 最有效,IC50 值分别为 10.17 ± 0.65 和 11.59 ± 0.59 μM。另一方面,受试化合物对正常肾上皮细胞系(Vero 细胞)的毒性较小。与新生霉素(IC50 值 0.28 ± 1.45 和 10.65 ± 1.02 µM,分别)。最后,进行分子对接以将化合物 8 定位到大肠杆菌 DNA B 和拓扑异构酶 IV 活性口袋中,以探索可能的结合构象。总之,化合物 8 可作为潜在的大肠杆菌 DNA B 和拓扑异构酶
