Abstract: The present invention relates to peptides having one or more stable, internally constrained ?-helices, and that include a sequence that mimics at least a portion of the C-terminal transactivation domain of HIF-1?. Also disclosed are pharmaceutical compositions containing these peptides and methods of using these peptides, for example to reduce gene transcription, treat or prevent disorders mediated by interaction of HIF-1? with CREB-binding protein and/or p300, reduce or prevent angiogenesis in a tissue, induce apoptosis, decrease cell survival and/or proliferation, and identify potential ligands of CREB-binding protein and/or p300.

Abstract: The present invention relates to oligooxopiperazines that mimic helix ?B of the C-terminal transactivation domain of HIF-1?. Also disclosed are pharmaceutical compositions containing these oligooxopiperazines and methods of using these oligooxopiperazines (e.g., to reduce gene transcription, treat or prevent disorders mediated by interaction of HIF-1? with CREB-binding protein and/or p300, reduce or prevent angiogenesis in a tissue, induce apoptosis, and decrease cell survival and/or proliferation).

Abstract: Nucleophosmin inhibitors are disclosed which inhibit the multimerization of nucleophosmin and the biological activity of nucleophosmin, such as the ability of nucleophosmin to inhibit apoptosis and inhibit cellular differentiation. These small molecule inhibitors are useful for treating diseases and disorders, such as cancer associated with dysregulated nucleophosmin expression. Methods for identifying small molecule inhibitors of nucleophosmin involving multimerization sites for nucleophosmin are also disclosed.

Abstract: Methods are provided for interfering with a hypoxia-mediated transcriptional pathway using an agent that binds to a hypoxia response element and inhibits transcription of a hypoxia inducible gene associated therewith. Also provided are methods of treating a patient with a solid tumors, and compositions useful for treating a patient having solid tumors, including, for example, by administering an agent that binds to a hypoxia response element in a cell. Agents for the methods of the invention are provided including compositions comprising a pyrrole imidazole polyamide or a pharmaceutically acceptable salt or complex thereof.
