辅助疾病预警与诊断的石胆酸衍生物设计与合成
Design and synthesis of lithocholic acid derivatives for disease early warning and diagnosis
设计合成了一种石胆酸衍生物并优化了其合成工艺。以石胆酸为起始原料,经酰胺化、还原、酯化、脱卤化氢、肟化等反应对石胆酸进行结构修饰和改造,得到可与Zn2+络合实现其浓度灵敏测定的衍生物3-{2-[2-(6-乙醛肟吡啶基)乙醛肟醚基]乙酸酯基}-胆甾烷-24-吗啉,纯度达98.6%,可用于辅助某些疾病的预警与诊断。优化后的合成工艺条件温和,适合工业化生产。
A derivative of lithocholic acid was designed and synthesized and its synthesis process was optimized.Starting from lithocholic acid,the structure was modified through a series of reactions including amidation,reduction,esterification,dehydrohalogenation,and oximation.The final product,3-{2-[2-(6-acetaldoxime pyridinyl) acetaldoxime ether] acetate ester-}-cholestan-24-morpholine,exhibited enhanced physiological activity on assisting in the early warning and diagnosis of some diseases,the purity of the product is 98.6%.The optimized synthetic route features mild reaction conditions,making it suitable for industrial-scale production.
