IOWH032 is a synthetic extracellular CFTR inhibitor, originally developed to treat diarrhea, that entered Phase II clinical trials in 2013 but did not progress further in clinical development. iOWH032 has low CFTR inhibition potency (IC50 > 5 uM) and hence rapid (seconds or less) dissociation from CFTR. iOWH032 inhibited secretion by nearly 70% as measured on a semi-quantitative fecal output scale.

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 uM.
