The present invention is directed to novel compounds according to formula (I) wherein R
1
, R
2
, and X are as defined herein. The invention also discloses methods of preparation, pharmaceutical compositions, and methods of disease treatment utilizing pharmaceutical compositions comprising these compounds. The compounds of this invention are novel therapeutic agents for the treatment of cancer, diabetes, metabolic diseases and skin disorders in mammalian subjects. These compounds are also useful modulators of gene expression. They exert their activity by interfering with certain cellular signal transduction cascades. The compounds of the invention are thus also useful for regulating cell differentiation and cell cycle processes that are controlled or regulated by various hormones or cytokines. The invention also discloses pharmaceutical compositions and methods of treatment of disease in mammals.
本发明涉及按照式(I)定义的新化合物,其中R1、R2和X如本文所定义。本发明还揭示了制备方法、制药组合物以及利用包含这些化合物的制药组合物治疗疾病的方法。本发明的化合物是哺乳动物主体中治疗癌症、糖尿病、代谢疾病和皮肤疾病的新型治疗剂。这些化合物也是有用的
基因表达调节剂。它们通过干扰某些细胞
信号转导级联来发挥作用。因此,本发明的化合物也有助于调节由各种激素或细胞因子控制或调节的细胞分化和细胞周期过程。本发明还揭示了哺乳动物疾病的制药组合物和治疗方法。
