Nepodin (Musizin) is a quinone oxidoreductase (PfNDH2) inhibitor isolate from Rumex crispus[1].Nepodin (Musizin) stimulates the translocation of GLUT4 to the plasma membrane by activation of AMPK[2].Nepodin (Musizin) has antidiabetic and antimalarial activities.
Nepodin (Musizin) exhibits significant IC50 values that are 0.74 and 0.79 μg/ml against P. falciparum chloroquine-sensitive (3D7) and P. falciparum chloroquine-resistant (S20), respectively[1].
Nepodin (Musizin) (orally administration; 2-10 mg/kg; 4 weeks) improves the impaired glucose tolerance of db/db mice, also decreases an increase in plasma insulin concentration of db/db mice in a dose-dependent manner[2]. Animal Model: C57BL/KsJ-db/db mice[2]
