Product Introduction
Mefloquine AI Summary
Mefloquine exhibits a diverse range of bioactivities. It shows significant antimalarial activity against various strains of Plasmodium falciparum, including chloroquine-resistant and multidrug-resistant strains, with IC50 values ranging from as low as 6.1 nM to 146.0 nM. In mouse models infected with Plasmodium berghei, it demonstrates a remarkable reduction in parasitemia by over 99.9% at a dose of 30 mg/kg, enhancing survival significantly. Additionally, it exhibits antiviral activity against JC polyomavirus and Zika virus with respective EC50 values of 4500.0 nM and 3600.0 nM, and potent inhibitory effects against Mycobacterium tuberculosis with a MIC of 5.0 µg/mL. Mefloquine also has notable binding affinities to human adenosine A2A and A1 receptors, with Ki values of 6553.0 nM and 14044.0 nM, respectively. Moreover, it inhibits specific cytochrome P450 enzymes and human ERG expressed in CHO cells with variable IC50 values. Owing to these multifaceted activities, Mefloquine is considered a promising candidate for the development of treatments across malaria, viral infections, and potentially other microbial and receptor-targeted conditions..

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
