Enhanced therapeutic efficacy of a novel self-micellizing nanoformulation-loading fisetin against acetaminophen-induced liver injury.

Abstract

Aim: To evaluate the feasibility of using dipotassium glycyrrhizinate (DG) as a nanocarrier-loading fisetin (FIT) with strengthened treatment efficacies against liver injury induced by acetaminophen overdose. Methods: DG-FIT was prepared, and its efficacy against liver injury induced by acetaminophen overdose was evaluated. Results: DG-FIT was successfully fabricated with excellentphysicochemical properties. DG-FIT could be easily dissolved inwater to form a clear micelle solution with high FIT encapsulation efficiency. FIT in DG-FIT exhibited a dramatically improved aqueous solubility. DG-FIT improved intestinal permeation. Regardingin vivo efficacies, DG-FIT exhibited significant effect against acetaminophen overdose bysuppressing oxidative stress and proinflammatory cytokines involved. Conclusion: DG-FIT formulation possibly represents a promising method for strengthening the efficacy of FIT against acetaminophen-induced liver injury.
