  • Patent number: 7531695
    Abstract: The present invention is directed to compounds having the structure (I) wherein R1, R2, R3, R4, R5 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.
