library composed of nitazoxanide‐based analogues was synthesized and assayed for increased antibacterial efficacy against the pyruvate–ferredoxin oxidoreductase (PFOR) using microorganisms Helicobacter pylori, Campylobacter jejuni and Clostridium difficile. Derivatives were found to recapitulate and improve activity against these organisms and select analogues were tested for their ability to disrupt
合成了一个由基于硝唑尼特的类似物组成的文库,并使用微生物幽门螺杆菌、空肠弯曲杆菌和艰难梭菌对丙酮酸-铁氧还蛋白氧化还原酶 (PFOR) 的抗菌功效进行了分析。发现衍生物可以概括并提高针对这些生物的活性,并测试了选择的类似物直接破坏 PFOR 酶的能力。该文库还针对葡萄球菌的活性进行了筛选,并鉴定出能够以低微摩尔最低抑制浓度抑制葡萄球菌和所有 PFOR 生物体的类似物,并且对人类包皮细胞的毒性较低。
