Abstract

Rabies, induced by rabies virus (RABV), still threaten global health all over the world, and no effective therapy is available for rabies currently. Recently, a series of natural plant components have been found to inhibit virus production. In this study, Z-Ligustilide, a natural component of Ligusticum chuanxiong Hort, was found to inhibit RABV replication. Initially, the concentration of cytotoxicity 50 % (CC50) of Z-Ligustilide in N2a and BSR cells were 429.9 μM and 335.5 μM, respectively, which both significantly restrict RABV production in a concentration-dependent manner. Moreover, Z-Ligustilide was found to mainly inhibit the replication stage of RABV. Specifically, Z-Ligustilide can suppress lipid droplet (LD) formation via directly inhibiting diacylglycerol Acyltransferase 1/2 (DGAT1/2) expression, which can further promote cellular lipid peroxidation, Fe2+ concentration, Reactive Oxygen Species (ROS), and induce Ferroptosis ultimately. Furthermore, Z-Ligustilide was demonstrated to increase Ferroptosis via Acyl-CoA synthetase long-chain family member 4 (ACSL4)- Lysophosphatidylcholine Acyltransferase 3 (LPCAT3)- Cytochrome P450 Oxidoreductase (POR) pathway. Above all, this study explored the Antiviral function of Z-Ligustilide, which provides a novel insight for developing anti-RABV drugs.
