Aim: To test the potential of orally administered citrate functionalized Mn3O4 nanoparticles (C-Mn3O4 NPs) as a therapeutic agent against hepatic fibrosis and associated chronic liver diseases.
Materials & methods: C-Mn3O4 NPs were synthesized and the pH dependent antioxidant mechanism was characterized by in vitro studies. CCl4 intoxicated mice were orally treated with C-Mn3O4 NPs to test its in vivo antioxidant and antifibrotic ability.
Results: We demonstrated ultrahigh efficacy of the C-Mn3O4 NPs in treatment of chronic liver diseases such as hepatic fibrosis and cirrhosis in mice compared with conventional medicine silymarin without any toxicological implications.
Conclusion: These findings may pave the way for practical clinical use of the NPs as safe medication of chronic liver diseases associated with fibrosis and cirrhosis in human subjects.
