Taurolithocholic acid-d₅ is deuterium labeled Taurolithocholic acid. Taurolithocholic acid is an orally active bile acid and antiviral agent. Taurolithocholic acid upregulates FADS2 by activating the TGR5-PI3K/AKT-SREBP2 signaling axis, inhibits SFTSV-induced ferroptosis, viral replication and viral entry of HBV/HDV, while reducing the release of IL-1β, lipid ROS and LDH. While exerting antiviral protective effects, Taurolithocholic acid also stimulates the recycling of hepatocellular membrane transporters, impairs canalicular bile acid secretion function, and induces hepatocyte cholestasis, apoptosis and acute hepatocellular injury. Taurolithocholic acid serves as an experimental model compound for hepatocellular cholestasis. At concentrations ≤200 μM, Taurolithocholic acid shows no cytotoxicity and does not activate the interferon pathway. Taurolithocholic acid not only protects mice from lethal SFTSV infection but also is suitable for studies related to severe fever with thrombocytopenia syndrome and cholestasis.
