Arsthinol
Arsthinol 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 and has been demonstrated to be effective against amoebiasis and yaws. It was marketed few years later by Endo Products.
Among trivalent organoarsenicals, arthinol was considered as very well tolerated. Recently, it was studied for its anticancer activity.
