COA 取扱説明書 Technical Support

Cinnarizine is an orally active, effective and selective inhibitor of L-type calcium channel Cav1.3 with an IC50 of 1.5 μM (in vestibular hair cells). Cinnarizine can cross the blood-brain barrier and regulate calcium homeostasis and dopamine neurotransmission. Cinnarizine inhibits the influx of calcium ions into smooth muscle cells by blocking L-type calcium channels, thereby relaxing vascular smooth muscle, improving cerebral circulation and reducing blood viscosity, while antagonizing dopamine receptors. Cinnarizine can be used in the study of vestibular vertigo, Meniere's disease and cerebrovascular diseases.

体外実験

Cinnarizine (1.5 μM; transient treatment) inhibits L-type calcium current (ICa) in a concentration-dependent manner in the voltage-gated calcium current assay of guinea pig vestibular type II hair cells, and the reversibility decreases with increasing concentration[1].
Cinnarizine (0.5 μM, 1 μM; transient treatment) significantly inhibits pressure-induced potassium current in the pressure-sensitive potassium current assay of guinea pig vestibular type II hair cells, and the inhibitory effect can be completely blocked by Charybdotoxin (HY-P0191)[2].
Cinnarizine (1-30 μM; 24 h) stimulates HAC15 cells with angiotensin II, reduces aldosterone concentration and CYP11B2 expression[3].

体内実験

Cinnarizine (10 mg/kg; oral; once daily; 6 weeks) induces local hair loss and oral dyskinesia in the parkin knockout model (PK-KO) of female mice, significantly reduced the motor activity of mice, and enhanced striatal dopamine metabolism and compensatory activation of the glutathione system[4].
Cinnarizine (2-10 mg/kg; intravenous injection; once daily; 30 days) has a dose-dependent pharmacokinetic profile in beagle dogs, causing reversible renal injury at 10 mg/kg, with a significant cumulative effect[5].

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

Animal Model: Female C57BL6/129SV parkin knock-out (PK-KO) mice and wild-type (WT) littermates (20-25 g, 14 months old) behavioral and neurochemical model[4]
Dosage: 10 mg/kg dissolved in drinking water
Administration: Oral administration via drinking water, once daily for 6 weeks.
Result: Behavioral Changes: Developed PK-KO mice focal alopecia and bucolingual dyskinesia, with motor activity reduced by 30-40% compared to baseline, while WT mice showed no significant behavioral alterations.
Neurochemical Alterations: Increased striatal dopamine (DA) levels by 26% in PK-KO mice, with DA metabolites DOPAC and HVA elevated by 49% and 19%, respectively. Increased glutathione (GSH/GSSG ratio) by 25% in the striatum, indicating compensatory anti-oxidative stress response.
Protein Expression: Decreased tyrosine hydroxylase (TH) protein levels by 15% in PK-KO striatum, while β-tubulin increased by 20%. Pro-apoptotic proteins Bax and Bclx ratio indicated enhanced neuronal apoptosis in PK-KO mice treated with cinnarizine.

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: ≥ 0.71 mg/mL (1.93 mM); Clear solution

    This protocol yields a clear solution of ≥ 0.71 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (7.1 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.

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.
