 | Compounds Binding to the N-Terminal Domains of STAT Proteins as Therapeutic Agents
Signal transducer and activator transcription (STAT) proteins, specifically STAT1, 2, 3, 4, 5a, 5b, and 6, are involved in the cellular and biological processes of cell proliferation, differentiation, apoptosis, host defense, and transformation. Constitutively active STAT proteins occur in many human tumor cells and cells transformed by oncoproteins. Inhibiting these STAT proteins has great therapeutic potential in the treatment of certain cancers.
The current invention describes a family of short peptides that bind to the N-terminus domains of STAT proteins and their use as therapeutic agents. These compounds are the first inhibitors that can directly bind to N-domains of STATs and exhibit a direct inhibitory effect. STAT1, 3, and 5 inhibitors can serve as potent therapeutic agents for the treatment of a variety of tumors and STAT 4 inhibitors can be used to control autoimmune disorders. More...
