In Vitro

In human embryonic kidney 293 cells, Umeclidinium bromide (GSK573719A) inhibits the human ether-a-go-go-related gene channel tail current in a concentration-dependent manner (IC50=9.4 μM)[1]. Umeclidinium bromide, previously known as GSK573719, is a novel high-affinity specific mAChR antagonist. It is a potent agent that demonstrates slow functional reversibility at cloned human M3 mAChRs and at endogenous mAChR in isolated human bronchus[2].

In Vivo

When Umeclidinium bromide (GSK573719A) is given once daily to mice for 5 consecutive days (0.025 μg intranasally), the level of inhibition on the fifth day is modestly increased above that obtained after a single administration to the same mice (60 versus 35%, respectively). After the fifth day of dosing, the mice are rested for 5 additional days, allowing bronchomotor tone to return to baseline levels. On the sixth day, the mice receive one last dose of antagonist and are once again challenged with Mch. The level of inhibition is essentially the same as that found on the first day of testing, indicating that tolerance is not evident with repeated intranasal delivery of Umeclidinium bromide. By contrast, when Umeclidinium bromide is given orally (2.0 mg/kg) to mice at a dose 100 times the ED50 value (intranasal), there is no observable protection against an Mch challenge[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

    Solubility: 2.5 mg/mL (4.92 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

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

    Solubility: 2.5 mg/mL (4.92 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Kinase Assay
[1]

Ligand binding assays with Umeclidinium bromide (GSK573719A) and [3H]-N-methyl scopolamine (0.5 nM) are performed using a scintillation proximity assay for M1, M2, and M3 mAChRs and a filtration assay for M4 and M5 mAChRs. For the scintillation proximity assay assay, membranes are incubated with wheat germ agglutinin beads in 50 mM HEPES buffer, pH 7.4, at 4°C for 30 minutes and then with the radioligand in a 96-well OptiPlate for 2 hours at room temperature in the presence of vehicle (1% DMSO) or GSK573719 (0.01-300 nM). At the end of the incubation, the plates are centrifuged (for 5 minutes at 2000g), and radioactivity is counted. For the filtration assay, membranes (M4 and M5) are similarly incubated in HEPES buffer containing the radioligand for 2 hours at room temperature in the presence of vehicle (1% DMSO) or Umeclidinium bromide (0.03-300 nM). Atropine is used as a reference agent. Reactions are terminated by rapid filtration through GF/C filters (glass microfiber binder free 1.2 μ). Membranes are washed with ice-cold 50 mM HEPES and transferred to scintillation vials. Radioactivity is counted in a Scintillation Counter. Reactions are terminated by rapid filtration. Data are obtained from three independent experiments. Specific binding is determined by subtracting nonspecific binding (using 0.3 μM atropine) from total binding. The inhibition constant (Ki) for Umeclidinium bromide is calculated. Membranes containing M3 mAChRs are also incubated for 2 hours at room temperature with increasing concentrations of [3H]-N-methyl scopolamine (0.08-9.24 nM) in the presence or absence of Umeclidinium bromide (0.2-0.5 nM) in 50 mM HEPES, pH 7.4. Nonspecific binding is determined using 10 μM atropine. The saturation data are converted to a scatchard plot for analysis[1].

Animal Administration
[1]

Mice[1]
Age-matched male BALB/c mice (23-25 gm) are pretreated intranasally (50 μL per mouse) with vehicle (0.9% saline) or Umeclidinium bromide at intervals (0.25-48 hours) prior to methacholine challenge, and placed into individual plethysmograph chambers. Fresh air is supplied by bias flow pumps to the chambers. After baseline respiratory [enhanced pause (Penh)] values are collected, the mice received methacholine (30 mg/mL or EC80) by aerosol delivery (flow=1.6 mL/min×2 minutes). An average Penh is then calculated for 5 minutes. Penh=[(expiratory time/relaxation time)−1]×(peak expiratory flow/peak inspiratory flow), and relaxation time is the amount of time required for 70% of the tidal volume to expire. In some cases, animals are treated on multiple, consecutive days as described in the figure legends. The data are expressed as the mean±S.E.M. percent inhibition of Penh or (mean Penh value of vehicle treated group-Penh for each drug-treated animal) divided by (mean Penh value of vehicle treated group)×100%. Data are analyzed using commercially available 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.
