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)[2] and has been demonstrated to be effective against amoebiasis and yaws. It was marketed a few years later by Endo Products (Balarsen, Tablets, 0.1 g).[3]

Among trivalent organoarsenicals, arsthinol was considered very well tolerated.[4] Recently, it was studied for its anticancer activity.[5][6]

Identification

Arsthinol has IUPAC name of N-[2-hydroxy-5-[4-(hydroxymethyl)-1,3,2-dithiarsolan-2-yl]phenyl] acetamide with a molecular formula of C11H14AsNO3S2 and is represented by the SMILES notation, CC(=O)NC1=C(C=CC(=C1)[As]2SCC(S2)CO)O.[7]

Properties

The molecular weight of Arsthinol is 347.3 g/mol, with a hydrogen bond donor count of 3 and a hydrogen bond acceptor count of 5. It has 3 rotatable bonds, an exact mass of 347.279 g/mol, and a monoisotopic mass of 346.963105 g/mol. The topological polar surface area is 120Ų, and the compound contains 18 heavy atoms. It has no formal charge, a complexity of 308, and contains no isotope atoms. There are no defined atom stereocenters, but there is 1 undefined atom stereocenter. The compound has no defined or undefined bond stereocenters, includes 1 covalently bonded unit, and is canonicalized.[8][9]
