QUINOXALINE INHIBITORS OF THE HEDGEHOG SIGNALLING PATHWAY

摘要

The invention provides novel inhibitors of hedgehog signaling that are useful as a therapeutic agents for treating malignancies where the compounds have the general formula I wherein A is a carbocycle or heterocycle; X is alkylene, NR₄C(O), NR₄C(S), NR₄C(NH), NR₄SO, NR₄SO₂, NR₄C(O)NH, NR₄C(S)NH, C(O)NR₄, C(S)NR₄, C(NH)NR₄, NR₄PO or NR₄PO(OH) wherein R₄ is H or alkyl; R₁ is selected from the group consisting of alkyl, cycloalkyl, aryl or a heterocycle each of which is optionally substituted with hydroxyl, halogen, amino, nitro, alkyl, acyl, alkylsulfonyl or alkoxy; R₂ is halogen, hydroxyl, alkyl, acyl or alkoxy each optionally substituted with hydroxyl, halogen, amino, nitro, alkyl, acyl, alkylsulfonyl or alkoxy; R₃ is halogen, hydroxyl, alkyl, acyl or alkoxy each optionally substituted with hydroxyl, halogen, amino, nitro, alkyl, acyl, alkylsulfonyl or alkoxy; m is 0-3; n is 0-3; and salts and solvates thereof.
