Solid Lipid Nanoparticles (SLNs) grafted with p-Aminophenyl-α-D-Manno-Pyranoside (APMP) and Folic Acid (FA) (APMP–FA–SLNs) were applied to encapsulate 4’-demethylepipodophyllotoxin 9-(4,6-O-ethylidene-β-D-glucopyranoside) (etoposide) (ETP) for promoting the anti-proliferation of malignant glioblastoma multiforme. ETP-loaded APMP–FA–SLNs (APMP–FA–ETP–SLNs) were used to penetrate the Blood–Brain Barrier (BBB) and retard the propagation of U87MG cells. An incorporation of APMP and FA increased the particle size, the cytotoxicity to U87MG cells and the permeability coefficient for propidium iodide and ETP across the BBB. In addition, an increase in the APMP and FA concentration reduced the zeta potential, the grafting efficiency of APMP and FA, the dissolution rate of ETP and the trans-endothelial electrical resistance. Immunochemical staining images evidenced that APMP–FA–ETP–SLNs could infiltrate the BBB via glucose transporter 1 and recognize U87MG cells via folate receptor. APMP–FA–ETP–SLNs can be an effective pharmaco-therapeutic formulation in targeting delivery to the brain and in inhibitory efficacy against tumorous cells for cancer therapy.

Chia-Hao Lee is now studying his PhD in Department of Chemical Engineering National Chung Cheng University since 2014. His subject is nanotechnology for drugs delivery and designing the carrier of drugs such as solid lipid nanoparticles.
