Cftr correctors and potentiators
Webtients are unlikely to benefit from F508del-CFTR cor-rector therapies, as they lack F508del in both alleles. It is therefore clear that in the case of F508del and other trafficking mutations, novel compounds have to be identified. Indeed, current data indicate that a combin-ation of CFTR correctors, potentiators, and molecules WebWhile most known CFTR modulator compounds have been discovered through screening assays using immortalized cell lines, an important pre-clinical cell-based model system …

WebFeb 1, 2024 · Pharmacological strategies targeting CFTR and other membrane channels as an alternative target in CF. ( A) CFTR correctors partially rescue the trafficking defect of F508del-CFTR or nonsense mutation in combination with nonsense-mediated decay inhibitors; CFTR potentiators enhance its channel activity once trafficked to the cell …
WebCFTR modulators, e.g., correctors, promote the transfer of F508del to the apical membrane, while potentiators increase CFTR activity. Corrector and potentiator double therapies modestly improve lung function, whereas triple therapies with two correctors and one potentiator indicate improved outcomes.
