Background: Genistein is a soy-derived isoflavone and phytoestrogen with antioxidant and neuroprotective activity. Genistein has intrinsically low oral bioavailability that affects its dose-response activities. Purpose: Nanotechnologies were used to obtain the delivery of genistein to the brain: lipid-based nanovesicles, transfersomes, loaded with the phytoestrogen were developed as potential therapeutic or preventive strategy against neurodegenerative diseases by intranasal administration. Methods: Phosphatidylcholine from soybean and different edge activators were used to prepare transfersomes. The effect of selected nanovesicles on the oxidative damage was studied in PC12 cell line. Results: Suitable nanovesicles as carrier of genistein were obtained; their composition affects deformability, drug permeation behavior and cytotoxicity. In particular, the formulation containing Span 80, GEN-TF2, showed efficiency of internalization into the cell and it was able to attenuate ROS formation and to reduce the amount of apoptotic cells generated by H2O2 treatment compared to genistein. Conclusion: GEN-TF2 was able to reduce the oxidative damage suggesting a possible antioxidant role of this drug delivery system. These obtained data confer to GEN-TF2 a potential antioxidant activity and then it could be used as adjuvant therapy in oxidative stress-related neurodegenerative diseases.
