    • 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 hydroxy, halogen, amino, nitro, alkyl, acyl, alkylsulfonyl or alkoxy; R2 is halogen, hydroxy, alkyl, acyl or alkoxy each optionally substituted with hydroxy, halogen, amino, nitro, alkyl, acyl, alkylsulfonyl or alkoxy; R3 is halogen, hydroxy, alkyl, acyl or alkoxy each optionally substituted with hydroxy, halogen, amino, nitro, alkyl, acyl, alkylsulfonyl or alkoxy; m is 0-3; n is 0-3; and salts and solvates thereof. The invention also provides methods of using these compounds for therapy and/or prophylaxis in a mammal of hyperproliferative diseases and angiogenesis mediated diseases due to their activity for inhibiting the hedgehog signaling pathway.
    • 本发明提供了可用作治疗恶性肿瘤的治疗剂的刺猬蛋白信号传导的新型抑制剂,其中化合物具有通式I:其中A是碳环或杂环; X是亚烷基,NR4C(O),NR4C(S),NR4C(NH),NR4SO,NR4SO2,NR4C(O)NH,NR4C(S)NH,C(O)NR4,C(S)NR4,C )NR4,NR4PO或NR4PO(OH),其中R4是H或烷基; R1选自烷基,环烷基,芳基或杂环,其各自任选被羟基,卤素,氨基,硝基,烷基,酰基,烷基磺酰基或烷氧基取代; R2是卤素,羟基,烷基,酰基或烷氧基,各自任选被羟基,卤素,氨基,硝基,烷基,酰基,烷基磺酰基或烷氧基取代; R3是卤素,羟基,烷基,酰基或烷氧基,各自任选被羟基,卤素,氨基,硝基,烷基,酰基,烷基磺酰基或烷氧基取代; m为0-3; n为0-3; 及其盐和溶剂合物。 本发明还提供了使用这些化合物治疗和/或预防哺乳动物由于其抑制刺猬蛋白信号通路的活性而引起的过度增殖性疾病和血管生成介导的疾病的方法。
