Clostridioides difficile is a leading health threat. This pathogen initiates intestinal infections during gut microbiota dysbiosis caused by oral administration of antibiotics. C. difficile is difficult to eradicate due to its ability to form spores, which are not susceptible to antibiotics. To address the urgent need for treating recurrent C. difficile infection, antibiotics that selectively target
艰难梭菌是主要的健康威胁。这种病原体在由口服抗生素引起的肠道微生物群失调期间引发肠道感染。艰难梭菌难以根除,因为它能够形成对抗生素不敏感的孢子。为了解决治疗复发性艰难梭菌感染的迫切需求,需要选择性靶向艰难梭菌而不是常见肠道微生物群的抗生素。我们在本文中描述了对艰难梭菌表现出强效和选择性活性的吡啶酰胺类抗菌剂。108种异烟酰胺4类似物的构效关系研究了一种对耐甲氧西林金黄色葡萄球菌和艰难梭菌具有同等活性的化合物。引入以类似物87为例的吡啶酰胺核心导致对艰难梭菌的极好的效力和选择性。吡啶酰胺类选择性靶向艰难梭菌和预防肠道菌群失调的能力有望用于治疗复发性艰难梭菌感染。
