Novel CA4-TEG-triazole-TEG-Cpt (codrug 9) was synthesized and self-assembled into a micelle structure that showed a great synergistic anticancer activity on HeLa cancer cells without affecting the viability of 3T3 normal cells.
合成并自组装成胶束结构的新型 CA4-TEG-triazole-TEG-Cpt (codrug 9),对 HeLa 癌细胞显示出巨大的协同抗癌活性,同时不影响 3T3 正常细胞的活力。
Folate Receptor Targeting and Cathepsin B-Sensitive Drug Delivery System for Selective Cancer Cell Death and Imaging
designed and synthesized an FR-mediated fluorescence probe (FA-Rho) and FR-mediated cathepsin B-sensitive drug delivery system (FA-GFLG-SN38). FA-GFLG-SN38 is composed of the FR ligand (folic acid, FA), the tetrapeptide substrate for cathepsinB (GFLG), and an anticancer drug (SN38). The rhodamine B (Rho)-labeled probe FA-Rho is suitable for specificfluorescenceimaging of SK-Hep-1 cells overexpressing FR
