大量研究表明,肿瘤细胞和肿瘤血管内皮细胞表面的分子表达状态与正常细胞存在较大差别,使区分肿瘤组织与正常组织成为可能。研究者们采用噬菌体展示组合文库、OBOC (One-bead One-compound)组合文库和 PSSPCLs (Positional Scanning-synthetic PeptideCombinatorial Libraries)等技术获得大量靶向肽,以此为载体,通过化学连接与细胞毒素形成 PDC,利用这些肽特异性靶向肿瘤细胞,在肿瘤细胞或组织的特异生理环境中(如低pH、高表达蛋白酶、高还原性)释放出携载的抗癌药物分子。基于上述机制获得的受体靶向PDC在乳腺癌、前列腺癌、黑色素瘤等多种肿瘤模型中,均已表现出比未偶联多肽的游离化学药物分子更有效的肿瘤治疗效果。 本文总结了近年来已被应用于PDC研究的靶向肽,以供科研研究使用,我司可合成多肽及多肽偶联小分子化合物,欢迎添加微信咨询沟通。
