  "description_excerpt": "This invention relates to carbazole compounds, to methods of preparing the compounds, to pharmaceutical compositions containing the compounds, and to their use as therapeutic agents. In particular, the invention relates to carbazole compounds and their use in a variety of therapeutic areas, including the treatment of cancers.\n\nThe frequency of cancer in humans has increased in the developed world as the population has aged. For some types of cancers and the stage of disease at diagnosis, morbidity and mortality rates have not improved significantly in recent years despite extensive research. Induction of cell death is one of the most attractive cancer treatment strategies. There is a significant need to identify agents that are capable of inducing cell death in tumor cells and/or that potentiate chemotherapeutic and radiation therapies.\n\nThe present invention is directed to compounds and compositions that induce cell death, and to therapeutic uses of the compounds in the treatment of a cancer and other conditions in individuals in need of such treatment. The present invention also is directed to methods of preparing the therapeutic compounds. More particularly, the present invention is directed to compounds and methods of treating diseases and conditions such as cancers, inflammatory diseases, microbial infections, viral infections, and protozoan infections. The compounds are useful in a method comprising administering a therapeutically effective amount of a compound of structural formula (I) to an individual in need thereof.",
