Biochem/physiol Actions KM11060 is a mutated F508del cystic fibrosis transmembrane conductance regulator (CFTR) corrector. The most common mutation (~90%) in the CFTR gene is a deletion of phenylalanine 508 (F508del). The mutation impairs folding, trafficking, membrane stability, and channel gating leading to reduced CFTR expression and chloride conductance in the apical membrane and other abnormalities. KM11060 is an analog of sildenafil, which restores a function of the F508del mutated CFTR chloride channel. KM11060 appears to be more potent than sildenafil, forskolin, and genistein. |
