CFTR Corrector 9（Cat No.:I043385）is a small molecule compound designed to improve the function of the cystic fibrosis transmembrane conductance regulator (CFTR) protein, which is defective in individuals with cystic fibrosis. CFTR Corrector 9 works by enhancing the proper folding and trafficking of the CFTR protein to the cell surface, where it regulates chloride ion transport. This correction of CFTR function helps improve lung function and reduce the symptoms of cystic fibrosis, offering potential therapeutic benefits for patients with CFTR mutations, particularly those who are not responsive to existing CFTR modulators.
