- Abstract
- The approach of using ferroptosis to treat cancer has garnered attention due to its promising potential. However, the effectiveness of this therapy is often limited by the inherent redox system in cancer cells and the presence of ferritin as an iron ion storage molecule. To address this issue, we have designed a polymeric iron oxide nanocomplex loaded with sulfasalazine as a ferritinophagy-assisted ferroptosis inducing agent. The nanocomplex is based on a pH-responsive drug releasing platform that enables improved ferroptosis anti-cancer therapy. The nanocomplex was synthesized using polymerized phenylboronic acid decorated with iron oxide and further loaded with sulfasalazine by interacting with polymerized phenylboronic acid. Upon entering cancer cells, the nanocomplex releases sulfasalazine at the lysosomal acidic pH, which causes the complex to degrade into the labile iron ion (Fe
