The disclosure discloses a linker compound, a polyethylene glycol-linker conjugate and a derivative thereof, and a polyethylene glycol-linker-drug conjugate. The linker compound as well as the conjugate thereof with the polyethylene glycol and the derivative thereof may be used for modifying a drug, and a modification reaction is simple and easy to carry out. Moreover, a reaction yield is high, and an application range of the modified drug is wide. The modified drugs gradually degrade from a chain of the conjugate in vivo, and may stay in a lesion (such as a cancer site) for a longer period of time, achieving purposes of sustained and controlled release, reducing an administration frequency, and greatly improving a bioavailability of the drug and a patient compliance.
该披露揭示了一种连接剂化合物,聚乙二醇连接剂共轭物及其衍生物,以及聚乙二醇连接剂药物共轭物。连接剂化合物以及其与聚乙二醇的共轭物和衍生物可用于修饰药物,修饰反应简单易行。此外,反应产率高,改性药物的应用范围广泛。修饰后的药物在体内逐渐从共轭链中降解,并可在病变部位(如癌症部位)停留更长时间,实现持续和受控释放的目的,减少给药频率,大大提高药物的生物利用度和患者依从性。
