    Description

    Lumacaftor (VX-809; VRT 826809) is a CFTR modulator that corrects the folding and trafficking of CFTR protein.

    IC50 & Target

    EC50: 0.1 μM (CFTR)[1]
    In Vitro

    In fischer rat thyroid (FRT) cells, Lumacaftor improves F508del-CFTR maturation by 7.1±0.3 fold (n=3) compared with vehicle-treated cells (EC50, 0.1±0.1 μM; n=3) and enhances F508del-CFTR-mediated chloride transport by approximately fivefold (EC50, 0.5±0.1 μM; n=3). At Lumacaftor concentrations greater than 10 μM, the response is reduced, resulting in a bell-shaped dose-response relationship with an IC50 of approximately 100 μM. Lumacaftor is orally bioavailable in rats and achieved in vivo plasma levels significantly above concentrations required for in vitro efficacy[1]. Lumacaftor produces a concentration-dependent increase in the HRP luminescence signal after incubation with cells at 37°C or 27°C in both cell lines, with a similar EC50 value of approximately 0.3 µM. In F508-HRP CFBE41o- cells at 37°C, Lumacaftor increases the signal maximally to approximately 250 luminescence arbitrary units (a.u.) over the DMSO control baseline of approximately 60 a.u., representing an approximately 4-fold signal increase. Similarly, with the R1070W-HRP CFBE41o- cells, Lumacaftor increases the signal maximally to approximately 220 a.u. over the DMSO control baseline of approximately 85 a.u., representing an approximately 2.5-fold signal increase. Therefore, both cell lines produced robust signals with a good dynamic range for high-throughput screening[2].

    In Vivo

    Oral dosing of 1 mg/kg Lumacaftor in male Sprague-Dawley rats results in a Cmax of 2.4±1.3 μM with a t1/2 of 7.7±0.4 h (mean±SD; n=3), indicating that that Lumacaftor is orally bioavailable and able to reach plasma levels that significantly exceeded EC50s for F508del-CFTR correction[1].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 3 mg/mL (6.63 mM); Clear solution

      This protocol yields a clear solution of ≥ 3 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (30.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% Corn Oil

      Solubility: ≥ 3 mg/mL (6.63 mM); Clear solution

      This protocol yields a clear solution of ≥ 3 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (30.0 mg/mL) to 900 μL Corn oil, and mix evenly.

    Screening is carried out using a Beckman Coulter Biomek FX platform. In one set of assays, R1070W-F508-CFTR-HRP (R1070W-HRP)-expressing CFBE41o- cells are incubated with 100 µL medium containing 25 µM test compounds and 0.5 μg/mL Doxycycline for 24 hours at 37°C. In a second set of assays, F508-CFTR-HRP (F508-HRP)-expressing CFBE41o- cells are incubated with 100 µL medium containing 25 µM test compounds, 2 µM Lumacaftor, and 0.5 μg/mL doxycycline for 24 hours at 37°C. All compound plates contain negative controls (DMSO) and positive controls (2 µM Lumacaftor). In both assays, the cells are washed four times with PBS, and HRP activity is assayed by the addition of 50 µL/well of HRP substrate. After shaking for 5 minutes, chemiluminescence is measured using a Tecan Infinite M1000 plate reader equipped with an automated stacker (integration time, 100 milliseconds)[2].

    Cell Assay
    [2]

    .A549 cells expressing F508-CFTR YFP are grown at 37°C/5% CO2 for 18-24 hours after plating. The cells are then incubated with 100 μL of medium containing test compounds for 18-24 hours. At the time of the assay, cells are washed with PBS and then incubated for 10 minutes with PBS containing forskolin (20 μM) and genistein (50 μM). Each well is assayed individually for I- influx by recording fluorescence continuously (200 milliseconds per point) for 2 seconds (baseline) and then for 12 seconds after rapid addition of 165 μL PBS in which 137 mM Cl- is replaced by I-. The initial I- influx rate is computed by fitting the final 11.5 seconds of the data to an exponential for extrapolation of initial slope, which is normalized for background-subtracted initial fluorescence. All compound plates contain negative controls (DMSO vehicle) and positive controls (5 µM Lumacaftor). Fluorescence is measured using a Tecan Infinite M1000 plate reader equipped with a dual syringe pump (excitation/emission 500/535 nm)[2].

    Animal Administration
    [1]

    Rats[1]
    Male rats (n=3 per dose group) are orally administered Lumacaftor in a vehicle consisting of 0.5% Tween80/0.5% methylcellulose/water at a dose volume of 5 mL/kg. The concentration of Lumacaftor in plasma samples is determined with a liquid chromatography/tandem MS method. Pharmacokinetic parameters are calculated byusing WinNonlin Professional Edition software.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
