compounded by the depleting arsenal of antibiotics has accelerated efforts toward development of antibiotics with novel mechanisms of action. In this report, we present a series of small molecular antibacterial peptoid mimics which exhibit high in vitro potency against a variety of Gram-positive and Gram-negative bacteria, including drug-resistant species such as methicillin-resistant Staphylococcus aureus
伴随着不断耗竭的抗生素库而出现的多药耐药细菌,加快了开发具有新作用机制的抗生素的努力。在本报告中,我们介绍了一系列小分子拟
肽模拟物,它们对多种革兰氏阳性和革兰氏阴性细菌具有很高的体外效价,包括耐药菌,例如耐
甲氧西林的
金黄色葡萄球菌和耐
万古霉素的肠球菌粪便。这些化合物的亮点是它们对主要的医院病原体
铜绿假单胞菌具有优越的活性。。这些快速杀菌的化合物对哺乳动物细胞无毒,主要通过细菌膜的透化和去极化作用。这些化合物在合成上简单且选择性地具有抗菌性,因此可以发展成为针对多药耐药细菌物种的新型治疗剂。
