Synthesis and characterization of protein nanohybrid systems for the brain delivery of Riluzole.

AIMS: Synthesis and Characterization of Protein NanoHybrid Systems for the Brain Delivery of Riluzole.

METHODS/MATERIALS: Fullerene is converted into carboxylated fullerene (CF) and then, prepared RZU-loaded BSA nanoparticles conjugated with CF.

RESULTS

The particle size and zeta potential of RZU-PNH were found to be 210 ± 1.15 nm and -18.5 ± 0.615 mV respectively, and entrapment efficiency and loading efficiency of RZU-PNH were found to be 98.8 ± 0.53% and 11.6 ± 0.43%, respectively. The XRD of the RZU-PNH shows the amorphism behavior and CD revealed that secondary structure of the protein mainly consists of α-helix andβ-sheet. The MTT assay showed 88.60% and 90.84% cell viability in both SH-SY5Yand N2a cell lines at a concentration of 20 μg/ml and also, no significant nasal ciliotoxicity was observed after incubation with RZU-PNH.

CONCLUSIONS

Obtained results indicated RZU-PNH formulation to treat amyotrophic lateral sclerosis.
