烟酸即3-吡啶甲酸,是小分子药物,以聚乙二醇-烟酸酯小分子药物为模型药物,通通过可降解的酯键键合于聚乙二醇上,获得PEG修饰的大分子前药。以二氯亚砜为偶联剂,把小分子药物键合于PEG上,便于纯化。

 

聚乙二醇-烟酸酯的制备合成方法:

步骤一:取聚乙二醇10. 6 g(2. 4 mmol),于100 mL圆底烧瓶中加入30 mL无水苯,在磁力搅拌下使其溶解。

**步:将溶解的聚乙二醇滴加至烟酰氯中,加毕,缓慢加入3.5 mL的三乙胺,氮气氛下磁力搅拌,于80C油浴下回流24 h,待反应结束后,滤除沉淀物,滤液浓缩,用无水乙醚沉淀得粗产物。

第三步:粗品用苯溶解放置过夜,抽滤,除去不溶物,滤液浓缩,无水乙醚沉淀;重复三次,真空干燥至恒量,得精制后的产物,收率85%。
