Hydrophilic linkers are useful for linking drugs to cell-binding ligands in ligand-drug conjugates, such as antibody-drug conjugates. The ligand-drug conjugate includes a cell-binding ligand capable of binding to a particular cell population, and a drug connected to the ligand by a hydrophilic linker. The hydrophilic linker includes one or more hydrophilic groups that render the linker hydrophilic. The hydrophilic linker may also include functional groups at the two termini for coupling to the drug and the cell-binding ligand respectively.
亲水连接体可用于连接配体-药物共轭物(如抗体-药物共轭物)中的药物与细胞结合配体。配体-药物共轭物包括能与特定细胞群结合的细胞结合配体,以及通过亲水连接体与配体连接的药物。亲水连接体包括一个或多个亲水基团,使连接体具有亲水性。亲水连接体的两个末端还可包括分别与药物和细胞结合配体偶联的官能团。
