Description

General description

A cell-permeable glycinyl hydrazone compound that acts as a potent, selective and reversible open-channel blocker of CFTR with intermediate speed (<1 min; 95% inhibition at 50 µM; K_i = 4.3 µM in CFTR-expressing FRT cells for apical membrane Cl^- current) and exhibits desirable aqueous solubility. Shown to produce inwardly rectifying CFTR Cl^- currents with reduced mean channel open time and suggested to directly interact with the channel pore at the extracellular side of the membrane. Displays minimal effects on P-glycoprotein and non-CFTR-mediated Cl^- currents, and is effective in nasal and intestinal epithelia in vivo.
