design and synthesis of novel pleuromutilin derivatives containing the (2-aminothiazol-4-yl)-4-methyl group, as well as their in vitro antibacterial activities against Gram-positive clinical bacteria. Most of the tested compounds displayed strong antibacterial activities against these methicillin-susceptible and methicillin-resistant bacteria. Particularly noteworthy compound 15 and its derivative 16e, both
由于在社区获得性感染病原体中由多药耐药性引起的日益严重的问题,迫切需要开发新型的抗生素来克服耐药性。在本文中,我们描述了含有(2-氨基噻唑-4-基)-4-甲基的截短侧耳素衍生物的设计与合成,以及它们对革兰氏阳性临床细菌的体外抗菌活性。大多数测试化合物对这些对甲氧西林敏感和耐甲氧西林的细菌显示出强大的抗菌活性。特别值得注意的化合物15及其衍生物16e,两者均显示出强效的抗菌性能(0.0625-0.5μg/ mL),优于阿莫西林和提洛米林。分子对接研究表明,截短侧耳素衍生物侧链上的氨基噻唑环通常可容纳在结合口袋中的短尾叶素核心附近,因此在整个分子的活性中起重要作用。本文报道的发现可能为人类临床使用的新型截短侧耳素衍生物的设计提供新的见解。
