Barbadin is a novel and selective β-arrestin/β2-adaptin interaction inhibitor, has IC50 values of 19.1 μM for β-arrestin1 and 15.6 μM for β-arrestin2. Barbadin blocks agonist-promoted endocytosis of the prototypical β2-adrenergic, V2-vasopressin and angiotensin-II type-1 receptors. Barbadin can induce apoptosis.

Description

Barbadin is a novel and selective β-arrestin/β2-adaptin interaction inhibitor, has IC50 values of 19.1 μM for β-arrestin1 and 15.6 μM for β-arrestin2. Barbadin blocks agonist-promoted endocytosis of the prototypical β2-adrenergic, V2-vasopressin and angiotensin-II type-1 receptors. Barbadin can induce apoptosis[1][2].

IC50 & Target

IC50: 19.1 μM (β-arrestin1); 15.6 μM (β-arrestin2)[1]
In Vitro

Barbadin (4 h) treatment reduces cell viability and induces apoptosis[2].
? Barbadin (2 h) treatment arrests breast cancer cells in G0/G1 phase[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 (7.50 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 (7.50 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.

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.
