Description_x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ GSK2193874 is a very potent, specific antagonist of TRPV4 ion channels (IC50 = 50 nM). Lung edema caused by high pulmonary venous pressure (PVP) is driven by TRPV4 activity. GSK2193874 blocks TRPV4-mediated calcium influx in cells expressing native and recombinant TRPV4, and inhibits vascular permeability and lung edema in isolated rodent and canine lungs subjected to high PVP. The compound also resolves pulmonary edema in murine myocardial infarction model.
