Plecanatide (acetate)

Plecanatide is a peptide agonist of the guanylate cyclase C receptor. It stimulates cGMP production in T84 colon cancer cells (EC50 = 170 nM). Plecanatide (10 ppm in the diet) reduces increases in the number of neoplastic colon epithelial cells expressing Ki-67, a marker of cell proliferation, induced by dextran sulfate (DSS, Cay-23250) in cancer-prone Apc+/Min-FCCC mice. It suppresses trinitrobenzenesulfonic acid-induced increases in abdominal contractions in a rat model of visceral hypersensitivity when administered at doses of 0.01 and 0.05 mg/kg. Formulations containing plecanatide have been used in the treatment of chronic idiopathic constipation.Formal Name: L-asparaginyl-L-alpha-aspartyl-L-alpha-glutamyl-L-cysteinyl-L-alpha-glutamyl-L-leucyl-L-cysteinyl-L-valyl-L-asparaginyl-L-valyl-L-alanyl-L-cysteinyl-L-threonylglycyl-L-cysteinyl-L-leucine, cyclic (4->12),(7->15)-bis(disulfide), monoacetate.
