The disclosure discloses a dendritic polyethylene glycol derivative and a preparation method and an application thereof. The dendritic polyethylene glycol derivative has a structure of formula (I), has multiple end functional groups, has a stronger water solubility in comparison with linear-chain polyethylene glycol, and can solve a problem of insufficient water solubility due to the increase of load when modifying an insoluble drug by the polyethylene glycol. The preparation method of the dendritic polyethylene glycol derivative provided by the disclosure has mild reaction conditions, is green and environmentally friendly, is low in cost, and is easy to implement industrialization.
该披露揭示了一种树枝状聚乙二醇衍生物及其制备方法和应用。该树枝状聚乙二醇衍生物具有式(I)的结构,具有多个末端官能团,在与线性链聚乙二醇相比具有更强的水溶性,并且可以解决由于通过聚乙二醇对不溶性药物进行修饰时载荷增加而导致水溶性不足的问题。该披露提供的树枝状聚乙二醇衍生物的制备方法具有温和的反应条件,绿色环保,成本低,易于实现工业化。
