Plecanatide, an analogue of Uroguanylin, is an orally active guanylate cyclase-C (GC-C) receptor agonist. Plecanatide activates GC-C receptors to stimulate cGMP synthesis with an EC50 of 190 nM in T84 cells assay. Plecanatide shows anti-inflammatory activity in models of murine colitis[1][2][3].
Plecanatide (1 nM-10 μM) activates GC-C receptor to stimulate cyclic guanosine monophosphate (cGMP) synthesis in a dose-dependent manner with EC50 of 190 nM in T84 cells[1].
Plecanatide (0.5 and 2.5 mg/kg, p.o.) ameliorates spontaneous and chemically induced colitis after treatment for 7 days in BALB/c mice, and 14 days in TCRα-/- mice[1].Plecanatide (0.005-5 mg/kg, once daily for 7 days) also shows anti-inflammatory activity in dextran sulfate sodium (DSS) and trinitrobenzene sulfonic (TNBS)-induced colitis in BDF-1 mice[1]. Animal Model: Female BALB/c mice (2-4 month old) are induced colitis by TNBS[1]
