Inhibitors of indoleamine 2,3-dioxygenase (IDO) are provided as are pharmaceutical compositions containing such inhibitors as well as the use of such inhibitors and compositions for the treatment of a condition in a mammalian subject characterized by pathology of the IDO-mediated tryptophan metabolic pathway. Such conditions may involve suppression of T-cell mediated immune response or may directly result from depletion of tryptophan or accumulation of a product of tryptophan degradation. Specific disease conditions include cataracts, age-related yellowing in the eye, neurodegenerative disorders, mood disorders, cancer and various bacteria/viral infections. IDO inhibitors of this invention are substituted naphthalene and anthracene diones. Novel compounds of this invention include the following taurine-substituted naphthaquinone structure.
