Description

Buspirone is an orally active 5-HT1A receptor agonist, and a dopamine D2 autoreceptorsant antagonist. Buspirone is an anxiolytic agent, and can be used for the generalized anxiety disorder research[1].

In Vitro

The anxiolytic and anti-depressant effects of Buspirone are produced by activating 5-HT1A autoreceptors and 5-HT1A heteroreceptors, respectively[1].
Buspirone (0-400 µg/mL; 6 hours) has cytotoxic effect in lymphocytes[2].
Buspirone (0-180 µg/mL; 0-3 hours; lymphocytes) induces ROS formation, mitochondrial membrane potential collapse(MMP), lipid peroxidation, lysosomal damage and elevation of glutathione disulfide (GSSG)[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[2]

Cell Line: Lymphocytes
Concentration: 0, 4, 20, 40, 200 and 400 µg/mL
Incubation Time: 6 hours
Result: Decreased cell viability in a dose-dependent manner.
In Vivo

Buspirone (1-5 mg/kg; i.p. and i.g.; for 5 days; C57BL/6N mice) reduces anxiety/depression behaviors[1].
Buspirone (1-5 mg/kg; i.p. and i.g.; for 5 days; C57BL/6N mice) restores immobilization stress (IS)-shifted β-diversity in the gut microbiota[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male C57BL/6N mice[1]
Dosage: 1 and 5 mg/kg
Administration: Oral gavage and intraperitoneal injection; for 5 days

Animal Model: Male C57BL/6N mice[1]
Dosage: 1 and 5 mg/kg
Administration: Oral gavage and intraperitoneal injection; for 5 days

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 (6.49 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% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (6.49 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 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.

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.
