Description

Citalopram hydrobromide is a selective serotonin reuptake inhibitor (SSRI). Citalopram hydrobromide inhibits 5-HT uptake into synaptosomes with an IC50 of 1.8 nM. Citalopram hydrobromideinhibits the 5-HT uptake in rabbit blood platelets with an IC50 of 14 nM. Antidepressant effect[1].

In Vitro

Drastically decreased IMR32 cell viability, 36%, 1% and 0% at respectively 50, 100 and 125 μM in IMR32 cell line.
In Vivo

Acute administration of Citalopram (1-10 mg/kg, i.p. 1 h before an elevated plus-maze test) to Spontaneously Hypertensive rats (SHRs), Lewis (LEW) rats, and Wistar-Kyoto (WKY) rats, i.e., rat strains differing for their emotionality, promotes anxiety, and/or hypoactivity, except in WKY rats. In the three strains, such a pretreatment increased central 5-HT levels and/or decreased 5-hydroxyindoleacetic acid levels[3].

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

Animal Model: Male rats from the SHR, LEW, and WKY strains, aged 6–8 weeks[3]
Dosage: 1, 3.3, or 10 mg/kg
Administration: Injected i.p.
Result: Increased significantly 5-HT in SHRs and WKY rats, and decreased 5-HIAA in all strains, in either a dose-dependent (LEW and WKY rats) or a dose-independent (SHRs) manner.

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 (6.17 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

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.
