CE-123
CE-123, or as the active enantiomer -CE-123, is an analog of modafinil, the most researched of a series of structurally related heterocyclic derivatives. In animal studies, CE-123 was found to improve performance on tests of learning and memory in a manner consistent with a nootropic effect profile. -CE-123 has pro-motivational effects in animals, reverses tetrabenazine-induced motivational deficits, and could be useful in the treatment of motivational disorders in humans.
