Gliomas are the most common type of tumor in the human central nervous system, characterized by high aggressiveness, elevated mortality, and poor prognosis. Therefore, developing new therapeutic strategies is crucial for improving glioma treatment. Temozolomide (TMZ) is widely used in glioma therapy due to its excellent ability to penetrate the blood-brain barrier. In this study, we synthesized HA-PEG@ICG using hyaluronic acid (HA) and polyethylene glycol (PEG), modified with the fluorescent compound indocyanine green (ICG), and thoroughly characterized the product's structure. Subsequently, compound 1 and TMZ were co-loaded onto this carrier to construct a synergistic drug delivery system (HA-PEG@ICG@1@TMZ). Additionally, we evaluated the inhibitory effects and mechanisms of HA-PEG@ICG@1@TMZ on glioma cell proliferation. Our study lays the foundation for further exploration of TMZ-based therapies for glioma treatment.
