IOWH032 is a synthetic CFTR inhibitor with IC50 of 1.01 μM in CHO-CFTR cell based assays. Phase 2. | [In vitro]
IOWH032 shows inhibitory activity against CFTR in T84-CFTR cell based assays with IC50 of 6.87 μM. | [In vivo]
In a mouse closed-loop model, IOWH032 causes a statistical significant inhibition against cholera toxin (CTX) induced secretion. IOWH032 (5 mg/kg) reduces the fecal output index by ~70% in a cecetomized rat model. |

IOWH032 is a synthetic?cystic fibrosis transmembrane conductance regulator (CFTR) ?inhibitor. | [Biological Activity]
iowh-032 is a potent and synthetic extracellular cystic fibrosis transmembrane conductance regulator (cftr) inhibitor with ic50 value of 1.01 μm in t84 and cho-cftr cell based assays [1]. the cftr chloride channel is the most attractive because it is the primary driver of secretion in cases of diarrhea caused by enterotoxigenic bacteria. cftr plays an important role in transepithelial fluid homeostasis through controlling the flow of chloride ions and thus the movement of water in and out of cells [1]. | [target]
