either for novel antibiotics or for improving the activities of the protein synthesis inhibitors already in use. Oxadiazole derivatives display strong bactericidal activity against a large number of bacteria, but their effects on trans-translation were recently questioned. In this work, a series of new 1,3,4-oxadiazole derivatives and analogs were synthesized and assessed for their efficiency as antimicrobial
病原细菌中抗生素耐药性的现实性和强度要求快速开发新的抗菌药物。在细菌中,反翻译是挽救翻译过程中被捕获的核糖体的主要质量控制机制。因为反式翻译是在真核生物中不存在,但必须避免核糖体失速,因此对细菌生存所必需的,它是无论是对新型抗生素或改善已在使用中的蛋白质合成抑制剂的活性有希望的靶点。恶二唑衍生物对大量细菌显示出很强的杀菌活性,但它们对反式翻译最近受到质疑。在这项工作中,合成了一系列新的1,3,4-恶二唑衍生物和类似物,并评估了它们作为抗多种革兰氏阳性和革兰氏阴性病原菌株的抗菌剂的效率。尽管在这些分子中观察到的抗菌作用强,事实证明,他们并不针对反式翻译体内,但他们肯定对其他细胞途径起作用。
