    Abstract: Novel heterocyclic compounds having a six membered ring structure fused to a five membered ring structure are found to be useful for the treatment and prevention of symptoms or manifestations associated with disorders affected by Interleukin-12 ("IL-12") intracellular signaling, such as, for example, Th1 cell-mediated disorders. The therapeutic compounds, pharmaceutically acceptable derivatives (e.g., resolved enantiomers, diastereomers, tautomers, salts and solvates thereof) or prodrugs thereof, have the following general formula: Each X, Y and Z are independently selected from a member of the group consisting of C(R3), N,N(R3) and S. Each R1, R2 and R3 is substituted or unsubstituted and is independently selected from a member of the group consisting of hydrogen, halo, oxo, C(1-20)alkyl, C(1-20)hydroxyalkyl, C(1-20)thioalkyl, C(1-20)alkylamino, C(1-20)alkylaminoalkyl, C(1-20)aminoalkyl, C(1-20)aminoalkoxyalkenyl, C(1-20)aminoalkoxyalkynyl, C(1-20)diaminoalkyl, C(1-20)triaminoalkyl, C(1-20)tetraminoalkyl, C(5-15)aminotrialkoxyamino, C(1-20)alkylamido, C(1-20)alkylamidoalkyl, C(1-20)amidoalkyl, C(1-20)acetamidoalkyl, C(1-20)alkenyl, C(1-20)alkynyl, C(3-8)alkoxyl, C(1-11)alkoxyalkyl, and C(1-20)dialkoxyalkyl.
