    The objective of the next set of experiments is to determine if the (i) super long-acting 2-AR agonists Indacaterol and Vilanterol inhibit TNF-α in a β-arrestin2-dependent manner, and (ii) whether β-arrestin2 is involved in the anti-inflammatory conversion leading to the up-regulation of IL-10 production by these β2-AR agonists.

    Description

    Vilanterol trifenatate (GW642444 trifenatate) is a long-acting β2-adrenoceptor (β2-AR) agonist with inherent 24-hour activity. The pEC50s for β2-AR, β1-AR and β3-AR are 10.37, 6.98 and 7.36, respectively.

    In Vitro

    The selectivity of Vilanterol trifenatate for β2-AR over the other β-AR receptor subtypes (β2 and β3) is established by testing the ability of Vilanterol to elicit concentration-dependent increases in cAMP in CHO cells expressing human β1-, β2-, and β3-AR. Vilanterol is demonstrated to be highly selective for the β2-AR with at least a 1000-fold selectivity over both β2- and β3-AR subtypes. This analysis results in a low-affinity pKD for [3H]Vilanterol of 9.44±0.07 (n=4) in the presence Gpp(NH)p and a high-affinity pKD of 10.82±0.12 (n=4) and a low-affinity pKD 9.47±0.17 (n=4) in the absence of Gpp(NH)p. In addition, a low-affinity pKD for [3H]Vilanterol of 9.52±0.24 (n=4) in the absence of Gpp(NH)p (37°C) is observed[1]. Vilanterol trifenatate is a novel inhaled long-acting β2-agonist with inherent 24 h activity in vitro in development as a combination with the inhaled corticosteroid fluticasone furoate for both COPD and asthma[2]. Vilanterol is a novel long-acting β2-agonist (LABA) with inherent 24-hour activity for once-daily clinical treatment of chronic obstructive pulmonary disease (COPD) and asthma in combination with the inhaled novel corticosteroid fluticasone furoate, also active for 24 hours[3].

    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: 2 mg/mL (2.58 mM); Clear solution; Need ultrasonic

      This protocol yields a clear solution of 2 mg/mL.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 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% (20% SBE-β-CD in Saline)

      Solubility: 2 mg/mL (2.58 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 2 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 (20.0 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.

    Saturation, association, and dissociation binding studies are performed for [3H]Vilanterol to determine receptor binding kinetics at the β2-AR (equilibrium dissociation constant (KD), total number of receptors (Bmax), association rate (kon), and dissociation rate (koff) are calculated). For saturation binding, membranes (in a volume of 1.4 mL to avoid ligand depletion) are incubated with increasing concentrations of [3H]Vilanterol (~0.01-1.3 nM) for 5 h before filtration. For association binding, membranes are incubated with different concentrations of [3H]Vilanterol (~0.1-1.9 nM) for varying incubation times up to 1 h before filtration. For dissociation binding, membranes are preincubated for 1 h with a fixed concentration of [3H]Vilanterol (~1.1 nM) before dissociation is initiated by a 1:20 dilution in binding buffer (containing 10 μM cold Vilanterol) and then incubated for varying times up to 8 h before filtration. Saturation binding is also completed for [3H]CGP12177 (increasing concentrations of ~0.01-2.8 nM) in the same format as described above for [3H]Vilanterol. To determine the affinity of β2-AR agonists and antagonists, competition binding displacement studies are completed in which membranes are incubated with a fixed concentration of [3H]Vilanterol (~0.2 nM) and increasing concentrations of unlabeled agonist/antagonist for 5 h before filtration. All competition binding displacement studies are completed in the presence of 100 µM Gpp(NH)p to ensure that binding curves are monophasic[1].

    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.
