COA Handling Instructions

Atovaquone (Atavaquone) is a potent, selective and orally active inhibitor of the parasite’s mitochondrial cytochrome bc1 complex. Atovaquone is against human and  P. falciparum cytochrome bc1 activity with IC50 values of 460 nM and 2.0 nM, respectively. Atovaquone is an antimalarial agent and has the potential for the investigation of neumocystis pneumonia, toxoplasmosis, malaria, and babesia.

Description

Atovaquone (Atavaquone) is a potent, selective and orally active inhibitor of the parasite’s mitochondrial cytochrome bc1 complex. Atovaquone is against human and  P. falciparum cytochrome bc1 activity with IC50 values of 460 nM and 2.0 nM, respectively. Atovaquone is an antimalarial agent and has the potential for the investigation of neumocystis pneumonia, toxoplasmosis, malaria, and babesia[1][2].

IC50 & Target

Plasmodium

 

In Vitro

Atovaquone targets to the Qo site of the Plasmodium cytochrome bc1 complex of the mitochondrial electron transport chain[1].
Atovaquone is against the development in the mosquito from gamete production, through fertilization, zygote formation and finally, to the development of the mature ookinete, and demonstrates an IC50 of 67 nM providing further evidence of the transmission blocking potential of this molecule[1].

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

In Vivo

Atovaquone (oral administration; 100 mg/kg; once daily) is against survival rates of mice, mice treated orally died within 22 days after discontinuation of sulfadiazine,while the control group died at day 14[2].

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

Animal Model: ICSBP−/− mice infected with 10 cysts of the ME49 strain of T. gondii[2]
Dosage: 100 mg/kg
Administration: Oral administration
Result: Improved mice survival rate to 22 days compared to vehicle.

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: 0.83 mg/mL (2.26 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 0.83 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 (8.3 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% Corn Oil

    Solubility: ≥ 0.83 mg/mL (2.26 mM); Clear solution

    This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
