Facile preparation of metal-organic frameworks-based hydrophobic anticancer drug delivery nanoplatform for targeted and enhanced cancer treatment.

Nowadays, cancer has been one of the major threats to human beings throughout the world. Nanomedicines have been demonstrated as a promising candidate for cancer chemotherapy. In this work, we facilely constructed a RGD (Arg-Gly-Asp) modified camptothecin@zeolitic imidazolate framework-8 (RGD@CPT@ZIF-8) as a novel metal-organic frameworks-based hydrophobic drug delivery system for targeted and enhanced cancer treatment. In our system, the nanoplatform exhibited the superior property of target to the cancer cells due to the function with RGD. More importantly, the RGD@CPT@ZIF-8 nanoplatform has shown the enhanced cancer cell treatment due to the excellent pH-responsive hydrophobic anticancer drug delivery and intracellular ROS generation. With the excellent targeting and enhanced therapy performance, we envision that the hydrophobic anticancer drug delivery system could become a potential therapeutic agent for targeted cancer treatment.
