Mild hydrolysis of the broad-spectrum anaerobic antibacterial and antiparasitic agent nitazoxanide 1 affords tizoxanide 2, which is a major metabolite of 1 retaining most of its activity; further metabolism of 2 leads to the O-aryl glucuronide 3, efficiently synthesised in four steps from benzyl salicylate and showing slight antibacterial activity.
温和水解广谱厌氧抗菌和抗寄生虫剂 nitazoxanide 1 产生主要代谢物 tizoxanide 2,该物质保留了大部分活性;接着,2 的进一步代谢生成 O-芳基葡萄糖醛酸盐 3,该物质通过从苄基水杨酸酯高效合成需四个步骤,并表现出轻微的抗菌活性。
