Uses

Used in Pharmaceutical Industry:
Plecanatide is used as a laxative for the treatment of chronic idiopathic constipation and irritable bowel syndrome with constipation. It functions by drawing water into the gastrointestinal tract, thereby softening the stool and facilitating its natural passage. This helps alleviate the symptoms of constipation and improves the quality of life for patients suffering from these conditions.

Enzyme inhibitor

This uroguanylin analogue (FW = 1681.90 g/mol; CAS 467426-54-6), also known by the codename SP-304, binds to and activates guanylate cyclase-C (GC-C) receptors (EC50 ≈ 0.3 μM) expressed on the epithelial cells lining turn sequentially activates protein kinase G-II and the chloride channel known as the Cystic Fibrosis Transmembrane-conductance Regulator (CFTR) to regulate ion and fluid transport, to promote epithelial cell homeostasis, and to maintain barrier function in the GI mucosa. Plecanatide is a hexadecapeptide that is structurally identical to uroguanylin, except for an glutamate substitution at position-3. Oral treatment with plecanatide at a dose range between 0.05-2.5 mg/kg per day is as effective as once-daily treatment with 5-amino salicylic acid (100 mg/kg) or sulfasalazine (80 mg/kg). Amelioration of colitis by the treatment with plecanatide or dolcanatide was not dose-dependent, most likely due to saturation of available GC-C receptors.
