Arsthinol
Arsthinol (INN) is an antiprotozoal agent. It was synthesized for the first time in 1949 by Ernst A.H. Friedheim by complexation of acetarsol with 2,3-dimercaptopropanol (British anti-Lewisite) and has been demonstrated to be effective against amoebiasis and yaws. It was marketed few years later by Endo Products (Balarsen, Tablets, 0.1 g). Among trivalent organoarsenicals, arsthinol was considered as very well tolerated. Recently, it was studied for its anticancer activity. References
