Title:	Guanylate cyclase receptor agonists for the treatment of tissue inflammation and carcinogenesis
Abstract:	A method of treatment of inflamed, pre-cancerous or cancerous tissue or polyps in a mammalian subject is disclosed. The treatment involves administration of a composition of at least one peptide agonist of a guanylate cyclase receptor and/or other small molecules that enhance intracellular production of cGMP. The at least one peptide agonist of a guanylate cyclase receptor may be administered either alone or in combination with an inhibitor of cGMP-dependent phosphodiesterase. The inhibitor may be a small molecule, peptide, protein or other compound that inhibits the degradation of cGMP. Without requiring a particular mechanism of action, this treatment may restore a healthy balance between proliferation and apoptosis in the subject's population of epithelial cells, and also suppress carcinogenesis. Thus, the method may be used to treat, inter alia, inflammation, including gastrointestinal inflammatory disorders, general organ inflammation and asthma, and carcinogenesis of the lung, gastrointestinal tract, bladder, testis, prostate and pancreas, or polyps.

Patent Claims:	1. A peptide consisting of SEQ ID NO:8, wherein said peptide is a (4,12; 7,15) bicycle and wherein said peptide binds a guanylate cyclase receptor and induces cGMP production. 2. A pharmaceutical composition in unit dose form comprising a guanylate cyclase receptor agonist peptide consisting of SEQ ID NO:8 and a pharmaceutically acceptable carrier, wherein said peptide is a (4,12; 7,15) bicycle and wherein said peptide binds a guanylate cyclase receptor and induces cGMP production. 3. The pharmaceutical composition of claim 2, wherein the unit dose form is selected from the group consisting of a tablet, a capsule, a solution and an inhalation formulation. 4. The pharmaceutical composition of claim 2, further comprising at least one compound selected from the group consisting of a cGMP-dependent phosphodiesterase inhibitor, an anti-inflammatory agent, an antiviral agent and an anticancer agent.
