macrolide antibiotic for the treatment of Clostridium difficile infections. Tiacumicin B is structurally characterized with two chlorine atoms substituted on the aromatic ring, which is installed by the halogenase TiaM. During the study on halide compatibility of TiaM, a facile and nonenzymatic iodination method of didechlorotiacumicin B was discovered, requiring NaI, acid and air for iodination at room
Tiacumicin B(也称为 fidaxomicin 或 difimicin)是一种市售的 18 元大环内酯抗生素,用于治疗艰难梭菌感染。Tiacumicin B 的结构特征是芳环上被两个
氯原子取代,由卤化酶 TiaM 安装。在研究 TiaM 的卤化物相容性期间,发现了一种简便、非酶促的双
