g551d-cftr

VRT-532 (CFpot-532) is an effective modulator of CFTR and is commonly used in studies of cystic fibrosis (CF) caused by CFTR defects. Modification of CFTR by this small molecule modulator can increase arylsulfatase B (ARSB), which is necessary to reduce the accumulation of sulphate glycosaminosaccharide (gag), thus reducing the accumulation of 4-chondroitin sulfate in cystic fibrosis.

Ivacaftor (VX-770) (VX-770) is a potentiator of CFTR targeting G551D-CFTR (EC50: 100 nM) and F508del-CFTR (EC50: 25 nM) in Fisher rat thyroid cells, respectively.

PG01 is a potent CFTR Cl-channel potentiator, effective against ΔF508 (Ka 0.3 μM), and also against E193K, G970R and G551D (CFTR mutants), with Kd values of 0.22 μM, 0.45 μM and 1.94 μM, respectively.PG01 increases ΔF508-CFTR Cl- currents upon addition of forskolin. F508-CFTR Cl-current upon addition of Forskolin, correcting the gating defect of CFTR mutants.

CP-628006 is a small molecule CFTR potentiator that effectively restores ATP-dependent channel gating to G551D-CFTR, the mutant form found in cystic fibrosis.

GLPG1837 (ABBV-974) is an effective CFTR potentiator, with EC50s of 3 nM and 339 nM for F508del and G551D CFTR, respectively.

Icenticaftor (QBW251) is an orally active potentiator of the CFTR channel.
