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.

Lumacaftor (VRT 826809) is a CFTR modulator that corrects the folding and trafficking of CFTR protein. It enhances F508del-CFTR protein maturation in FRT cells (EC50: 100 nM).

Bamocaftor is a CFTR channel (DeltaF508-CFTR mutation) corrector for CF transmembrane conductance regulators designed to restore F508del-CFTR protein function. Combined use of tezacaftor and VX-561 for the treatment of cystic fibrosis patients with F508del/MF.

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

CFTR corrector 2 (FDL169) is a novel and potent CFTR (Cystic fibrosis transmembrane conductance regulator) corrector for treating cystic fibrosis (CF) patients who carry the F508del mutation.

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

(Rac)-Tezacaftor ((Rac)-VX-661) is a racemic mixture of the F508del CFTR corrector, Tezacaftor, used in cystic fibrosis research [1].

RNF5 inhibitor inh-02, a potent E3 ubiquitin ligase RNF5/RMA1 inhibitor, demonstrates significant efficacy in rescuing F508del-CFTR with an EC50 of 2.2 uM in bronchial epithelial cells homozygous for the F508del mutation. This compound is valuable for cystic fibrosis research[1].

GLPG2451 is a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator that effectively enhances the function of low-temperature-rescued F508del CFTR with an EC50 of 11.1 nM.

KM11060 is a novel corrector of the F508del-CFTR trafficking defect, Correcting F508del-CFTR trafficking, increasing the amount of functional CFTR at the plasma membrane.

C4 Ceramide is a bioactive sphingolipid and cell-permeable analog of naturally occurring ceramides. [1] [2] [3] It inhibits IL-4 production by 16% in EL4 T cells stimulated with phorbol 12-myristate 13-acetate when used at a concentration of 10 μM. [1] C4 Ceramide is cytotoxic to SK-BR-3 and MCF-7/Adr breast cancer cells (IC50s = 15.9 and 19.9 μM, respectively). [2] C4 Ceramide also increases maturation and stability of cystic fibrosis transmembrane conductance regulator (CFTR) proteins bearing the F508 deletion (F508del) mutation, enhances cAMP-activated chloride secretion, and suppresses secretion of IL-8 in primary epithelial cells isolated from patients with cystic fibrosis.[3]
