Using a high-throughput screen for drugs developed by the research team, they discovered that auranofin – a drug approved by the US Food and Drug Administration 25 years ago for rheumatoid arthritis – is very effective in targeting an enzyme that protects amebae from oxygen attack (thus enhancing sensitivity of the amebae to reactive oxygen-mediated killing). This parasite causes amebic dysentery and liver abscesses and results in the death of more than 70,000 people worldwide each year. Research by a collaborative group of scientists from UC San Diego School of Medicine, UC San Francisco and Wake Forest School of Medicine has led to identification of an existing drug that is effective against Entamoeba histolytica.
