Some simplified adociaquinone B analogs and a series of 1,4-naphthoquinone derivatives were synthesized and tested against the three enzymes Cdc25B, MKP-1, and MKP-3. Cdc25B and MKP-1 in particular are enzymes overexpressed in human cancer cells, and they represent potential molecular targets for novel cancer chemotherapeutic treatments. A number of analogs exhibited significant inhibitory activity against these enzymes, and the bioassay data in addition to structure-activity relationships of these compounds will be discussed.

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 bacterial/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.
