Chemical Structure

Biological activities

VX-809 is a cystic fibrosis transmembrane conductance regulator (CFTR) modulator. VX-809 is used to treat cystic fibrosis. VX-809 improves CFTR function in at least one organ (sweat gland). VX-809 reduces elevated sweat chloride values in a dose-dependent manner. [1] In cultured human bronchial epithelial cells, VX-809 improves F508del-CFTR processing in the endoplasmic reticulum and enhances chloride secretion to approximately 14% of non-CF human bronchial epithelial cells with an EC50 of 81 nM. F508del-CFTR corrected by VX-809 reveals biochemical and functional characteristics similar to normal CFTR, including biochemical susceptibility to proteolysis, residence time in the plasma membrane, and single-channel open probability. VX-809 enhances F508del-CFTR maturation and chloride transport in FRT cells. In FRT cells, VX-809 improves F508del-CFTR maturation by 7.1 fold compared with vehicle-treated cells. At VX-809 concentrations greater than 10 µM, the response is reduced, resulting in a bell-shaped dose??esponse relationship with an IC50 of approximately 100 µM. VX-809 enhances chloride and fluid transport in cultures of CF airway epithelial cells.[2]


In vitro: VX-809 is dissolved in DMSO.[2]
