Clostridium difficile infection (CDI) is a public health threat that results in 14,000 annual deaths in the United States. Challenges involve the production of CDI spores that can remain dormant for years and the production of toxins that damage the gut. Current therapies for CDI include vancomycin and metronidazole, but neither inhibits spore or toxin production. Thus, recurrence of infection occurs in 25% of patients and there are no antibiotics that are effective for multiple recurrences. We describe oxadiazoles with activity against C. difficile, including the highly virulent NAP1/027 strain with increased production of toxins A and B, as well as the additional binary toxin. Oxadiazole 2 is poorly absorbed, thus advantageously achieving high concentrations in the gut. The compound targets peptidoglycan synthesis and inhibits vegetative cells, spores, and toxin production.
Clostridium difficile感染(CDI)是美国每年导致14,000人死亡的公共卫生威胁。挑战包括CDI孢子的产生,这些孢子可以休眠数年,并且产生可以损害肠道的毒素。目前CDI的治疗包括万古霉素和甲硝唑,但是两者都不能抑制孢子或毒素的产生。因此,25%的患者会复发感染,并且没有有效的抗生素可用于多次复发。我们描述了对C. difficile具有活性的噁唑烷,包括高度致病的NAP1 / 027菌株,其毒素A和B的产量增加,以及其他二元毒素。噁唑烷2难以被吸收,因此在肠道中可以获得高浓度。该化合物靶向肽聚糖合成,抑制营养细胞,孢子和毒素的产生。
