FA-GC-PBA

FA-GC-PBA is a targeted, reactive oxygen species (ROS)-responsive nanotherapeutic platform developed for the treatment of cancers overexpressing the folate receptor, such as cervical cancer. The system consists of a glycol chitosan (GC) backbone functionalized with folic acid (FA) for active tumor targeting and phenylboronic acid (PBA) for ROS-triggered payload release. In preclinical research, this polymer is used to encapsulate selenium nanoparticles (SeNPs) to form FA-ReRSeNPs. This precision-driven nanotherapeutic enhances the delivery of selenium to tumor sites while minimizing off-target toxicity. Mechanistically, the released selenium inhibits the PI3K/AKT signaling pathway, which induces apoptosis and suppresses the proliferation of human cervical cancer cells (e.g., HeLa and SiHa).
