Provided herein are water-soluble prodrugs. The prodrugs of the invention comprise a water-soluble polymer having three or more arms, at least three of which are covalently attached to an active agent, e.g., a small molecule. The conjugates of the invention provide an optimal balance of polymer size and structure for achieving improved drug loading, since the conjugates of the invention possess three or more active agents releasably attached to a multi-armed water soluble polymer. The prodrugs of the invention are therapeutically effective, and exhibit improved properties in-vivo when compared to unmodified parent drug.
本文提供了
水溶性前药。该发明的前药包括具有三个或更多臂的
水溶性聚合物,其中至少三个臂与活性剂,例如小分子,共价连接。本发明的共轭物提供了一种优化的聚合物大小和结构的平衡,以实现改善的药物装载,因为本发明的共轭物具有三个或更多的活性剂可释放地连接到多臂
水溶性聚合物上。本发明的前药具有治疗效果,并在体内表现出比未经修改的母药更好的性质。
