  • Patent number: 6878715
    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.

  • Patent number: 6693105
    Abstract: Disclosed are therapeutic compounds having the formula: (R)j—(CORE MOIETY), including resolved enantiomers, diastereomers, hydrates, salts, solvates or mixtures thereof where j is an integer from one to three. The core moiety is a bicyclic ring structure having at least one heterocyclic ring that contains five to six ring atoms and up to two nitrogen heteroatoms. R is selected from the group consisting of hydrogen, halogen, hydroxyl, amino, substituted or unsubstituted benzyl, C1-6 alkyl or C1-6 alkenyl, and at least one R has the formula I: n is an integer from 1 to 20, at least one of X or Y is —OH. Another of X or Y, which is not —OH, is hydrogen, CH3—, CH3—CH2—, CH3—(CH2)2—or (CH3)2—CH2—, and each W1, W2, and W3 is independently hydrogen, CH3—, CH3—CH2—, CH3—(CH2)2— or (CH3)2—CH2—.
