Description

Amitraz is a non-systemic acaricide and insecticide with alpha-adrenergic agonist activity that interacts with octopamine receptors in the central nervous system and inhibits monoamine oxidase and prostaglandin synthesis[1][2].

IC50 & Target

Mite

 

In Vitro

Amitraz (25-150 μM, 10 days) inhibits the activity of IRE/CTVM19 cells (from Ixodes ricinus) and modulates the expression of their ABC transporters[1].

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

Real Time qPCR[1]

Cell Line: IRE/CTVM19 cells
Concentration: 25, 50, 100, 150 μM
Incubation Time: 10 days
Result: Resulted in a significant decrease in cell viability of IRE/CTVM19 cells compared to the control group (150 μM).

Real Time qPCR[1]

Cell Line: IRE/CTVM19 cells
Concentration: 25, 50, 100, 150 μM
Incubation Time: 10 days
Result: Induced a dose-dependent downregulation of ABCB1 gene expression and upregulates ABCB10 gene expression at 50 μM.
In Vivo

Amitraz (0-30 mg/kg, p.o., once daily for 19 weeks) exerts dose-dependent toxic effects on maternal and fetal development in pregnant female Sprague-Dawley rats[2].

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

Animal Model: Pregnant female sprague-Dawley rats (10 weeks old)[2]
Dosage: 0, 3, 10, 30 mg/kg
Administration: Oral gavage (p.o.), once daily for 19 days
Result: Exhibited significant maternal toxicity and developmental toxicity, including increased fetal mortality, reduced fetal weight, and abnormalities in external, visceral, and skeletal development (30 mg/kg/day).
Caused mild maternal toxicity and minimal developmental toxicity (10 mg/kg/day).
Did not induce maternal or developmental toxicity (3 mg/kg/day).

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 (8.52 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 (8.52 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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.
