Disclosed are water soluble polymeric reagents comprising the structure POLY-[Y—S—W]
x
, where POLY is a water soluble polymer; Y is a hydrocarbon-based spacer group, x is 1 to 25, and S—W is a thiol, protected thiol, or thiol-reactive derivative. Preferably, the water soluble polymer is a PEG polymer. Also disclosed are conjugates of such polymeric reagents with pharmaceutically relevant molecules, and methods of their formation and use.
本发明涉及一种水溶性聚合物试剂,其包括结构POLY-[Y—S—W]x,其中POLY是一种水溶性聚合物;Y是一个碳氢基间隔基,x为1至25,S—W是一个硫醇,受保护的硫醇或硫醇反应衍生物。优选,该水溶性聚合物为PEG聚合物。本发明还涉及这种聚合物试剂与药物相关分子的结合物,以及它们的形成和使用方法。
