confirmed by means of their spectral data. The antimicrobial activity of the newly synthesized compounds 4-10 was evaluated by agar well diffusion, and they showed good activity. Compounds 4, 5, and 9 gave the most promising activity in this study. Most of the tested compounds possessed MIC values ranging from 50 to 500 µg/mL. Furthermore, docking studies were carried out on enoyl reductase from E. coli
制备了一系列线性二肽衍生物(4-10),并通过合成N-(2-(2-肼基-2-氧代乙基氨基)-2-氧代乙基)烟酰胺(4)对其进行了评估。化合物4与4-氯苯甲醛或4-羟基苯甲醛反应,分别得到the5和6。另一方面,将化合物4与异氰酸苯酯或异硫氰酸甲酯偶联,分别得到化合物7和8。将后面的化合物(7和8)与氯乙酸偶合,分别得到恶唑烷(9)和噻唑烷(10)。通过其光谱数据证实了新合成的二肽化合物。通过琼脂充分扩散评价了新合成的化合物4-10的抗菌活性,它们显示出良好的活性。在这项研究中,化合物4、5和9具有最有希望的活性。大多数测试化合物的MIC值为50至500 µg / mL。此外,还对来自大肠杆菌的烯酰还原酶和来自白色念珠菌活性位点的细胞色素P450 14α-甾醇脱甲基酶(Cyp51)进行了对接研究。七个测试化合物的MolDock得分分别在-117和-171之间以及-107和-179之间。
