PPQ-102 inhibites CFTR chloride current with IC 50 approximately 90 nM. PPQs are uncharged at physiological pH, so not subject to membrane potential-dependent cellular partitioning or block efficiency. PPQ-102 prevents cyst expansion and reduces the size of preformed cysts in a neonatal kidney organ culture model of polycystic kidney disease. PPQ-102 is the most potent CFTR inhibitor identified to date.
