    Description: IOWH-032 (IOWH032; IOWH 032) is a potent and synthetic CFTR (Cystic fibrosis transmembrane conductance regulator) inhibitor with antifibrotic activity. It inhibits CFTR with IC50s of 1.01 μM and in CHO-CFTR and T84-CFTR cell based assays, respectively. IOWH-032 rapidly blocked and potentiated hCFTR activity in a concentration-dependent manner with apparent Kd value of 6.1 nM and 0.64 nM, respectively. However, IOWH-032 did not potentiate and only blocked mCFTR with an apparent Kd value of 42.9 μM.

    In Vitro

    In vitro activity: IOWH032 shows inhibitory activity against CFTR in T84-CFTR cell based assays with IC50 of 6.87 μM.

    In VivoIn 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.
    Animal modelA cecetomized rat model
    Formulation & DosageDissolved in DMSO; ~5 mg/kg; p.o.
