In Vitro

Batefenterol is a novel first-in-class inhaled bifunctional compound possessing both muscarinic antagonist (MA) and β2-adrenoceptor agonist (BA) properties (MABA). In competition radioligand binding studies at human recombinant receptors, batefenterol displays high affinity for hM2 (Ki=1.4 nM), hM3 muscarinic receptors (Ki=1.3 nM) and hβ2-adrenoceptors (Ki=3.7 nM). Batefenterol behaves as a potent hβ2-adrenoceptor agonist (EC50=0.29 nM for stimulation of cAMP levels) with 440- and 320-fold functional selectivity over hβ1- and hβ3-adrenoceptors, respectively[1].

In Vivo

In the guinea pig bronchoprotection assay, inhaled Batefenterol produces potent, dose-dependent inhibition of bronchoconstrictor responses via MA (ED50=33.9 μg/mL), BA (ED50=14.1 μg/mL), and MABA (ED50=6.4 μg/mL) mechanisms. Significant bronchoprotective effects of Batefenterol are evident in guinea pigs via MA, BA, and MABA mechanisms for up to 7 days after dosing[1]. In guinea pig isolated trachea expressing native muscarinic M3 and β2, batefenterol produces smooth muscle relaxation through a dual mechanism involving competitive antagonism of the M3 receptor (EC50=50 nM) and agonism of the β2 receptor (EC50=25 nM). The combined effect on both muscarinic receptors and β2 receptors is more potent than either function working alone (EC50=10 nM). Batefenterol exhibits a rapid rate of clearance and short half-life[2].

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: ≥ 2.5 mg/mL (3.38 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (3.38 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 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 (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay
[1]

CHO-K1 cells stably transfected with each receptor subtype are incubated with increasing concentrations of batefenterol for 20 minutes at 37°C. The cells are stimulated with an EC90 concentration of the muscarinic agonist oxotremorine. Oxotremorine elicits a Gq-mediated calcium-release event, which in turn caused the calcium-sensitive dye to bind to calcium and fluoresce upon stimulation with a 488 nm laser light source. The change in fluorescence is measured by the FLIPR for 3 minutes, and the peak height in fluorescence is taken as the maximal response to generate the concentration-response curve for batefenterol[1].

Animal Administration
[1]

Guinea pigs: Batefenterol is dissolved in water. Guinea pig trachea is dissected and isolated. The tracheal rings are initially tensioned to 1 g and allowed to equilibrate for 1 hour before evoking contraction with a submaximal concentration of either methylcholine (MCh; 10 µM), in the presence of propranolol (10 µM), or histamine (HIS; 30 µM) to assess relaxant effects via MA and BA mechanisms, respectively. Relaxation through the MABA mechanism is evaluated in tissues precontracted with MCh in the absence of propranolol. After the contractile tone attained a plateau, the batefenterol (0.1 nM to 100 µM) is added cumulatively in half log increments, with each concentration being added after achieving a steady-state relaxation response to the previous concentration. After the last concentration of test compound, theophylline (2.2 mM) is added to establish maximum relaxation[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.
