Quinacrine …. Mepacrine has been shown to bind to the prion protein and prevent the formation of prion aggregates in vitro, and full clinical trials of its use as a treatment for Creutzfeldt–Jakob disease are under way in the United Kingdom and the United States. However, despite a multitude of clinical studies on the use of mepacrine and female sterilization, no randomized, controlled trials have been reported to date and there is some controversy over its use.
