Abstract
ABSTRACT Poor drug delivery to the tumour site and harmful drug effects on the nearby healthy tissue are the two main issues with chemotherapeutic treatments for glioma. This study tests the efficacy of a chitosan dual delivery system loaded with rutin and aucubin to treat glioma. It was shown in vitro that rutin/aucubin loaded chitosan nanoparticlesignificantly inhibited U87 cells and promoted apoptosis, and the combination therapy results were superior to those of each compound used alone. The rutin-aucubin combination decreased the glioma cell’s ability to migrate. The chitosan rutin-aucubin nanocomposites showed time dependent cell uptake in U87 cells when labelled with RBITC ANG. At a low dose of 0.156 μg/mL chitosan rutin-aucubin successfully inhibited tumour growth and adhesion and ~ 43% necrosis was observed in mitochondrial membrane potential (ΔΨm) assay. In conclusion, rutin and aucubin drugs were codelivered which inhibited tumour proliferation by inducing cellular apoptosis at a low dose. This showed the system’s potential to effectively enhance glioma therapy.
