Modafinil sulfone

Modafinil sulfone (code name CRL-41056) is an achiral, oxidized metabolite of modafinil, a wakefulness-promoting agent. It is one of two major circulating metabolites of modafinil, the other being modafinil acid. Modafinil sulfone is also a metabolite of the modafinil prodrug, adrafinil. Modafinil sulfone is also a metabolite of armodafinil, the (R)-(–)-enantiomer of modafinil, as oxidation to the sulfone removes the chiral center at the sulfur atom. Modafinil sulfone has been described as inactive,^[1] and similarly to modafinil acid, does not appear to contribute to the wakefulness-promoting effects of modafinil.^[2][3][4] However, like modafinil, modafinil sulfone was found to show anticonvulsant properties in animals, indicating that it does possess some biological activity.^[5]
