With only two new classes of antibiotics developed in the last 40 years, novel antibiotics are desperately needed to combat the growing problem of multidrug-resistant and extensively drug resistant bacteria, particularly Gram-negative bacteria. Described in this letter is the synthesis and antibiotic activity of 1,2,4-triazolidine-3-thiones as narrow spectrum antibiotics. Optimization of the 1,2,4
在过去的40年中,仅开发了两类新的抗生素,因此迫切需要新的抗生素来解决多重耐药性和广泛耐药性细菌(尤其是革兰氏阴性细菌)日益严重的问题。在这封信中描述的是1,2,4-三唑烷-3-硫酮作为窄谱抗生素的合成和抗生素活性。1,2,4-三唑烷-3-硫酮骨架的优化确定了一种对多种菌株具有多重耐药性和广泛耐药性的鲍曼不动杆菌具有有效抗生素活性的小分子。这个小分子还在鲍曼不动杆菌的马洛菌(Galleria mellonella)感染模型中显示了单剂量的体内活性。 代表着针对这种细菌病原体的一类药物的开发有希望的开端。
