Abstract
Neurodegenerative diseases (NDDs) are mainly induced by oxidative stress which produces excessive reactive oxygen species (ROS). Quercetin (QU) is a potent antioxidant with some effects on NDDs. This study prepared and characterized a novel glucose-modified QU liposome (QU–Glu–Lip), aiming not only to overcome QU’s poor water solubility and bioavailability but also to deliver more QU to brain tissue to enhance its neuroprotective effect. QU–Glu–Lip possessed encapsulation efficiency (EE) of 89.9%, homogenous particle sizes (116–124 nm), small PDI value (<0.3), zeta value −1.363 ± 0.437 mV, proper pH and salt stability, and proper cytotoxicity. The glucose-modified liposome penetrated the blood–brain barrier (BBB) mediated via the glucose transporter 1 (GLUT1) and was taken by neuronal cells more efficiently than liposome without glucose, according to bEnd.3 and PC12 cell tests. QU–Glu–Lip attenuated H2O2-induced oxidative damage to PC12 with higher cell viability (88.42%) and lower intracellular ROS compared to that of QU. QU–Glu–Lip had higher brain target ability and delivered more QU to neuronal cells, effectively exerting the antioxidative neuroprotection effect. There is potential for the QU–Glu–Lip application for more effective treatment of NDDs.
