작용 메커니즘 (Mechanism of Action)

특징
Higher specificity and efficacy relative to other CFTR defect drugs.
Targets/IC50/Ki
F508del-CFTR
(Fisher rat thyroid cells)
0.1 μM(EC50)
시험관 내(In vitro)

Lumacaftor (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, this compound 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, it (3 μM) 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, the agent 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 it exhibits single-channel open probability of 0.39 similar to normal CFTR of 0.40. Unlike VX-770, it is not a CFTR potentiator, as acute addition has no effect on F508del-CFTR function. In contrast to VRT-325 and Corr-4a, it 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 it is specific for CFTR. It in combination with VRT-325 or Corr-4a has additive effect on CFTR-mediated chloride transport in cultured F508del-HBE.

키나아제 분석
F508del-CFTR maturation
FRT cells stably expressing F508del-CFTR are treated with increasing concentrations of Lumacaftor (VX-809) for 48 hours. After incubation, cells are harvested in ice-cold D-PBS solution (without calcium and magnesium) and pelleted at 1,000 × g at 4 °C. Cell pellets are lysed in 1% Nonidet P-40, 0.5% sodium deoxycholate, 200 mM NaCl, 10 mM Tris, pH 7.8, and 1 mM EDTA plus protease inhibitor mixture (1:250) for 30 minutes on ice. Lysates are spun for 10 minutes at 10,000 × g at 4 °C to pellet nuclei and insoluble material. Approximately 12 μg total protein is heated in Laemmli buffer with 5% β-mercaptoethanol at 37 °C for 5 minutes and loaded onto a 3% to 8% Tris-acetate gel. The gel is transferred to nitrocellulose and processed for Western blotting by using monoclonal CFTR antibody or polyclonal to GAPDH. Blots are developed by enhanced chemiluminescence. Quantification of the relative amounts of bands C and GAPDH is performed by using NIH ImageJ analysis of scanned films.
