Verkningsmekanism (Mechanism of Action)

Egenskaper	Higher specificity and efficacy relative to other CFTR defect drugs.
Targets/IC₅₀/Ki	F508del-CFTR (Fisher rat thyroid cells) 0.1 μM(EC50)
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.
Kinasanalys	F508del-CFTR-mognad
Kinasanalys	FRT-celler som stabilt uttrycker F508del-CFTR behandlas med ökande koncentrationer av Lumacaftor (VX-809) i 48 timmar. Efter inkubation skördas cellerna i iskall D-PBS-lösning (utan kalcium och magnesium) och pelleteras vid 1 000 × g vid 4 °C. Cellpellets lyseras i 1 % Nonidet P-40, 0,5 % natriumdeoxikolat, 200 mM NaCl, 10 mM Tris, pH 7,8, och 1 mM EDTA plus proteashämmarblandning (1:250) i 30 minuter på is. Lysater centrifugeras i 10 minuter vid 10 000 × g vid 4 °C för att pelletera kärnor och olösligt material. Cirka 12 μg totalt protein upphettas i Laemmli-buffert med 5 % β-merkaptoetanol vid 37 °C i 5 minuter och laddas på en 3 % till 8 % Tris-acetatgel. Gelen överförs till nitrocellulosa och bearbetas för Western blotting med användning av monoklonal CFTR-antikropp eller polyklonal till GAPDH. Blottar utvecklas med förbättrad kemiluminiscens. Kvantifiering av de relativa mängderna av band C och GAPDH utförs med hjälp av NIH ImageJ-analys av skannade filmer.
In vivo	Lumacaftor (VX-809; VRT 826809) is a CFTR modulator that corrects the folding and trafficking of CFTR protein.
