Abstract

Enterovirus 71 (EV71), a prominent pathogen associated with hand, foot, and mouth disease (HFMD), has been reported worldwide. To date, the advancement of effective drugs targeting EV71 remains in the preliminary experimental stage. In this study, magnolol demonstrated a significant dose-dependent inhibition of EV71 replication in vitro. It upregulated the overall expression level of nuclear factor erythroid 2 - related factor 2 (Nrf2) and facilitated its nucleus translocation, resulting in the increased expression of various Ferroptosis inhibitory genes. This process led to a reduction in Reactive Oxygen Species (ROS) accumulation induced by viral Infection. Additionally, magnolol exhibited a broad-spectrum Antiviral effect against enteroviruses. Notably, treatment with magnolol substantially enhanced the survival rate of EV71-infected mice, attenuated viral load in heart, liver, brain, and limb tissues, and mitigated tissue inflammation. Taken together, magnolol emerges as a promising candidate for the development of anti-EV71 drugs.
