Abstract

The main purpose of this research was to prepare and to characterize ferulic acid-loaded nanostructured lipid carrier (FA-NLC) to evaluate the cytotoxic effect on human glioblastoma cancer U87MG cells. First of all, the influence of different materials on mean size and homogeneity of NLC prepared by a low energy organic solvent-free method was investigated.Technological characterization (encapsulation efficiency, mean particle size, homogeneity and in vitro release profile) was performed on the selected NLC in comparison to others lipid carriers, nanoemulsion and SLN. Furthermore, the thermal behavior of NLC and SLN was investigated using Differential Scanning Calorimetry (DSC) in order to evaluate their structure. Biological studies (MTT bioassay and caspase-3 cleavage) on the selected NLC showed no cytotoxic effects of the unloaded tested NLC. Besides, the effectiveness of FA-loaded NLC was higher compared to the free drug. Cells treated with FA or FA-loaded NLC showed a greater effect compared to idebenone (IDE) or IDE-loaded NLC, respectively. These results strongly support that FA-loaded NLC could be potentially used for the treatment of glioblastoma.
