Taurolithocholic Acid-d₅ sodium 

Taurolithocholic Acid-d₅ (sodium) is the deuterium labeled Taurolithocholic acid sodium salt. Taurolithocholic Acid sodium salt is an orally active bile acid and antiviral agent. Taurolithocholic Acid sodium salt 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 sodium salt 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 sodium salt serves as an experimental model compound for hepatocellular cholestasis. At concentrations ≤200 μM, Taurolithocholic Acid sodium salt shows no cytotoxicity and does not activate the interferon pathway. Taurolithocholic Acid sodium salt not only protects mice from lethal SFTSV infection but also is suitable for studies related to severe fever with thrombocytopenia syndrome and cholestasis^[1][2][3][4].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
