Arsthinol
Arsthinol is an organoarsenic compound with the formula. A antiprotozoal agent, it was first reported in 1949. It arises by the reaction of acetarsol with 2,3-dimercaptopropanol and has been demonstrated to be effective against amoebiasis and yaws. It was marketed a few years later by Endo Products.
Among trivalent organoarsenicals, arsthinol was considered very well tolerated. Recently, it was studied for its anticancer activity.
