This study prepared an in-situ thermo-sensitive hydrogel of berberine hydrochloride (BH) based on glycyrrhetinic acid (GA) modified nano graphene oxide (NGO). The physicochemical properties and anti-tumor activity of the hydrogel were investigated. The results showed sustained and temperature-dependent drug release from the hydrogel, and enhanced tumor targeting. Additionally, the hydrogel exhibited enhanced inhibitory effect when combined with laser irradiation.
Malignant tumor is one of the major diseases with high morbidity and mortality. The purpose of this study is to prepare berberine hydrochloride (BH) in situ thermo-sensitive hydrogel based on glycyrrhetinic acid (GA) modified nano graphene oxide (NGO) (GA-BH-NGO-gel). NGO was taken as the photosensitizer, GA was taken as the target molecule, and BH was taken as the model drug. The physicochemical properties and anti-tumor activity in vivo and in vitro were also studied. This subject could provide a certain theoretical basis for the chemo-photothermal therapy combined treatment of malignant tumor. The release behavior of GA-BH-NGO-gel in vitro presented sustained and temperature-dependent drug release effect. The anti-tumor activity studies in vivo and in vitro had shown that GA-BH-NGO-gel had stronger anti-tumor activity, which could be targeting distributed to the tumor tissues. Moreover, the inhibitory effect of GA-BH-NGO-gel was enhanced when combined with 808 nm of laser irradiation. In this research, the chemo-photothermal combination therapy was applied into the tumor treatment, which may provide certain research ideas for the clinical treatment of malignant tumor.
