and m are as defined herein. The compounds of this invention are novel therapeutic agents for the treatment of cancer, 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. In particular, the invention relates to compounds that induce apoptosis of cancer cells and therefore may be used for the treatment or prevention of cancer, including advanced cancers and pre-cancerous cells. The invention also discloses pharmaceutical compositions and methods of treatment of disease in mammals.
本发明涉及具有结构(I)的化合物,其中R1、R2、R3、R4、R5和m的定义如本文所述。本发明的化合物是哺乳动物受体中治疗癌症、代谢性疾病和皮肤疾病的新型治疗剂。这些化合物也是有用的
基因表达调控剂。它们通过干扰某些细胞信号传导级联来发挥作用。因此,本发明的化合物也对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的调节有用。特别是,本发明涉及诱导癌细胞凋亡的化合物,因此可用于治疗或预防癌症,包括晚期癌症和癌前细胞。本发明还揭示了哺乳动物疾病的药物组合物和治疗方法。
