小分子聚乙二醇(PEG)链接剂,可用于修饰各类生物药物,通过正离子亲脂类脂质体纳米颗粒形成配方材料,将可能即时装载靶向分子、实现对任何药物的挂载,可为建立针对肿瘤患者的个性化治疗药物库提供支持。
烟酸即3-吡啶甲酸,是临床上有意义的小分子药物,但存在诸如诱发溃疡病、加重糖尿病等副作用,从而限制了它的临床应用。本文以聚乙二醇-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。此方法简单且收率高,成本低。
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。
第二步: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%。
