The present invention relates to compositions for the treatment of cancerous tissues in warm-blooded animals containing one or two anticancer agents attached to polymeric carriers having monomer units derived from one or more of N-(2-carboxypropyl)methacrylamide (2-CPMA), N-(3-carboxypropyl)methacrylamide (3-CPMA), N-(2-aminopropyl)methacrylamide (2-APMA) and/or N-(3-aminopropyl)methacrylamide (3-APMA) are also included. Anticancer agents in compositions can be attached to said polymeric carrier by side-chains which can be susceptible to hydrolysis by lysosomal enzymes intracellularly. Compositions can also include a targeting ligand attached to the polymeric carrier, optionally through a second linker.
该发明涉及用于治疗温血动物体内癌组织的组合物,其中包含附着在聚合物载体上的一种或两种抗癌药物,所述聚合物载体具有源自N-(2-羧基丙基)甲基丙烯酰胺(2-CPMA)、N-(3-羧基丙基)甲基丙烯酰胺(3-CPMA)、N-(2-氨基丙基)甲基丙烯酰胺(2-APMA)和/或N-(3-氨基丙基)甲基丙烯酰胺(3-APMA)中的一个或多个单体单元。组合物中的抗癌药物可以通过在细胞内易受溶酶体酶水解的侧链附着在所述聚合物载体上。组合物还可以包括附着在聚合物载体上的靶向配体,可选地通过第二连接剂连接。
