摘要(Abstract)：

目的:对马蹄金素衍生物(研发代号Y101)代谢产物M8、M9的合成工艺进行优化并制备合格样品。方法:以L-酪氨酸甲酯盐酸盐为原料,设计不同的合成工艺,经过酰化、水解、苄基化、烷基化、催化氢化、N-氧化等反应合成替芬泰的主要代谢产物M8、M9,所得化合物经1H NMR,13C NMR,ESI-MS进行结构确证,并用高效液相色谱对其进行分析检测。结果:完成了M8、M9合成工艺路线的选择与优化,制备了合格的M8和M9样品。结论:优选的合成工艺制备所得的M8、M9样品纯度达到了95%以上。
Objective: To design and optimize a synthetic route for the synthesis of M8 and M9 and the metabolites of the new drug Tyrophentide(Y101)-an anti-hepatitis B candidate,so as to prepare qualified M8 and M9 for further study. Methods: Two different synthetic routes were designed for the synthesis of M8 and M9 using L-tyrosine methyl ester hydrochloride as the starting material by acylation,hydrolysis,benzylation,alkylation,catalytic hydrogenation and N-oxidation reaction. The structures of the synthesized compounds were confirmed by1 H NMR,13 C NMR and ESI-MS,and the purity of M8 and M9 were analyzed through high performance liquid chromatography(HPLC). Results: A synthetic route for the large scale synthesis of M8 and M9 was developed and used for the preparation of qualified samples of M8 and M9. Conclusion: The purity of M8 and M9 prepared for the optimized synthetic route was more than 95%. The obtained samples can be used for the biological activities and toxicity detection of M8 and M9.
