The disclosure provides methods of synthesis of polymeric scaffolds, e.g., those useful for conjugating with a protein based recognition-molecule (PBRM) to form PBRM-polymer-drug conjugates, and PBRM-polymer-drug conjugates thereof. The methods according to the disclosure allow for large-scale preparation of polymeric scaffolds having a high purity. In some embodiments, the methods according to the disclosure also allow for the preparation of scaffolds and conjugates thereof in better yield than previously used methods for preparing same. Also disclosed are methods of purifying polymeric scaffolds.
本公开提供了聚合物支架的合成方法,例如,用于与基于蛋白质的识别分子(PBRM)共轭以形成PBRM-聚合物-药物共轭物及其PBRM-聚合物-药物共轭物的方法。根据本公开的方法可以大规模制备高纯度的聚合物支架。在某些实施例中,根据本发明公开的方法还可以制备支架及其共轭物,其产率比以前使用的制备方法更高。本发明还公开了纯化聚合物支架的方法。
