Carbimazole is an orally active antithyroid agent which rapidly converts to Methimazole after absorption and prevents thyroid peroxidase enzyme from iodinating and coupling the tyrosine residues on thyroglobulin, hence reducing the production of thyroxine. Carbimazole also displays anti-inflammatory and neuronal-protective activities, suggesting its application for hyperthyroidism and neurological research.

Description

Carbimazole is an orally active antithyroid agent which rapidly converts to Methimazole after absorption and prevents thyroid peroxidase enzyme from iodinating and coupling the tyrosine residues on thyroglobulin, hence reducing the production of thyroxine. Carbimazole also displays anti-inflammatory and neuronal-protective activities, suggesting its application for hyperthyroidism and neurological research[1][2][3].

In Vitro

Carbimazole (0.01-2 mM, 6 h) inhibits the global translation of protein in SK-N-SH cells[1].
Carbimazole (0.5 mM, 12-72 h) inhibits hypoxic SK-N-SH cell injury and preserve intracellular ATP content in an oxygen-free atmosphere through inhibiting protein synthesis and activating MAPK[1].

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

Western Blot Analysis [1]

Cell Line: SK-N-SH
Concentration: 0.01-2 mM
Incubation Time: 6 h
Result: Induced the phosphorylation of eEF2 at Thr56 in a dose- and time-dependent manner through the phosphorylation of AMPK, resulting in a global translational inhibition.
In Vivo

Carbimazole (10, 15, 20 mg/animal/day, p.o., 21 d) shows mainly dose-dependent responses of basic physiological parameters in rabbits[2].

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

Animal Model: local breed adult healthy male rabbits
Dosage: 10, 15, 20 mg/animal/day
Administration: Oral gavage (p.o.) for 21 d
Result: Decreased rectal temperature, respiration rate, heart rate, the packed cell volume, Hb concentration and total leukocyte count, significantly decreased plasma glucose level;
Increased serum levels of total protein, globulins while serum albumin level decreased;
Lowered serum urea level while there was an increase in serum urea level with increase in dose level;
Increased serum cholesterol level in a dose-dependent 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 (13.42 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 (13.42 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.
