Niclosamide (Cat.No:A000928) is an anthelmintic drug used to treat tapeworm infections in humans and animals. It works by disrupting the energy production process in the parasites, leading to their death. In recent research, niclosamide has shown promise for its potential anti-cancer, anti-inflammatory, and antiviral properties.

Overview of Clinical Research

Niclosamide is a mitochondrial oxidative phosphorylation uncoupler and a MTOR protein inhibitor. Hyundai Bioscience and Korean authorities planned a efficacy trial for COVID-2019 infections in 2021.
