Biochemical Activity
Adrafinil ({diphenylmethyl}sulfinyl-2 acetohydroxamic acid; Olmifin) is a prodrug of the stimulant Modafinil and was developed as a powerful stimulant and wakefulness and alertness-promoting (eugregoric) substance.
It is the first discovered eugeroic (eugregoric) agent, and was the ‘grandfather’ of a family of eugeroic compounds, with the end result of Modafinil. Adrafinil is of relevance to researchers involved in studies pertaining to stimulant effects, novel stimulant development, and research into the biochemical pathways of eugeroic substances.
Adrafinil is sometimes considered as functional in athletes for use as a stimulant. As a result, it is a banned substance in competitive sports – banned by the World Anti-Doping Agency (WADA) for its stimulant-like effects.
