摘要

四环素破坏酶（TDases）是四环素类抗生素失活酶的一种，它通过 C11a 氧化作用使所有已知的四环素类抗生素失活，这被认为是一种临床威胁。为了提供更多有关这种酶失活和含氧三环素的信息，我们在此报告利用 m-CPBA 和添加剂通过仿生途径对四环素及其衍生物的 C11a 位进行化学氧化。含氧三氯乙酸的结构（2h、2i）已通过 X 射线分析得到证实，含氧三氯乙酸的进一步转化（2e、2i）也已完成。

Biomimetic oxidation of tetracycline and derivatives at C11a

Tetracycline destructases (TDases), a type of TC-inactivating enzymes, inactivate all known TC antibiotics by C11a oxidation, which is considered as a clinical threat. To provide more information on this enzymatic inactivation and oxygenated TCs, we report here a chemical oxidation of Tetracycline and its derivatives at the C11a position using m-CPBA with additives via biomimetic pathways. The structures of the oxygen-containing TCs (2h, 2i) were confirmed by X-ray analysis, and further transformations were performed with oxygen-containing TCs (2e, 2i).
