Triclabendazole-d3 is the deuterium labeled Triclabendazole (HY-B0621). Triclabendazole is an orally active parasite inhibitor. Triclabendazole has anti-Leishmania activity and induces gasdermin E (GSDME)-dependent pyroptosis by caspase-3 activation. Triclabendazole can be used for the research of fasciola hepatica[1][2][3].
