VX-809 (Lumacaftor)通过促进突变型CFTR(F508del-CFTR)的成熟,从而纠正常见于囊性纤维化的CFTR突变,EC50为0.1 μM。
Information
Lumacaftor (VX-809) Lumacaftor (VX-809, VRT 826809) acts to correct CFTR mutations common in cystic fibrosis by increasing mutant CFTR (F508del-CFTR) maturation, EC50 of 0.1 μM in fisher rat thyroid cells. Phase 3.
In vitro
VX-809 acts at the level of the ER to allow a fraction of the F508del-CFTR to adopt a properly folded form, to exit the ER and mobilize to the cell surface for normal functioning. In Fischer rat thyroid (FRT) cells expressing F508del-CFTR, VX-809 treatment significantly improves F508del-CFTR maturation by 7.1 fold with an EC50 of 0.1 μM, and enhances F508del-CFTR-mediated chloride transport by approximately 5 fold with EC50 of 0.5 μM, while VRT-768 has higher EC50 values of 7.9 μM and 16 μM, respectively. In HEK-293 cells expressing F508del-CFTR, VX-809 (3 μM) treatment increases F508del-CFTR exit from the ER by 6 fold, reaching levels comparable to 34% of CFTR. In primary human bronchial epithelial (HBE) cells with F508del-CFTR mutation, VX-809 increases CFTR maturation and enhances chloride secretion with EC50 of 350 nM and 81 nM, respectively, more efficacious than Corr-4a and VRT-325. F508del-CFTR corrected by VX-809 exhibits single-channel open probability of 0.39 similar to normal CFTR of 0.40. Unlike VX-770, VX-809 is not a CFTR potentiator, as acute addition of VX-809 has no effect on F508del-CFTR function. In contrast to VRT-325 and Corr-4a, VX-809 does not improve the processing of the normal or mutant forms of hERG or P-gp, as well as other disease-causing mislocalized proteins, including α1-antitrypsin Z mutant (E342K-α1-AT) or N370S-β-glucosidase, suggesting that VX-809 is specific for CFTR. VX-809 in combination with VRT-325 or Corr-4a has additive effect on CFTR-mediated chloride transport in cultured F508del-HBE.
