In Vitro

Giardia lamblia, a flagellated protozoan, is the most common causative agent of persistent diarrhea worldwide^[1].
Nitazoxanide exhibits effect on G. lamblia trophozoite proliferation in axenic culture with an IC₅₀ of 2.4 μM^[1].

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

Cell Viability Assay^[1]

Cell Line:	Human cancer colon Caco2 cells were incubated with increasing numbers of Giardia lamblia trophozoites (10³ to 10⁶ parasites per well)
Concentration:	30 μM
Incubation Time:	24 hours
Result:	70 to 90% of the trophozoites remained attached to the Caco2 cells for a period of 24 to 48 h in the absence of Nitazoxanide and at an initial inoculum density of 10⁵ parasites per well. The number of parasites still attached to Caco2 cells after 24 h decreased to less than 20% of the control value in the presence of 30 μM Nitazoxanide with an inoculum density of 10⁵ trophozoites.

In Vivo

Nitazoxanide exhibits a wide spectrum of in vivo activity against a broad spectrum of intestinal parasites, such as Giardia lamblia, Entamoeba histolytica, Trichomonas vaginalis, the apicomplexan Cryptosporidium parvum, and enteric bacteria infecting animals and humans^[1].
Nitazoxanide (50, 75 or 100 mg/kg/day; administered daily by intragastric for up to 25 days) reduces the mortality of Japanese encephalitis virus (JEV) strain-infected mice and protected mice from a lethal dose challenge of JEV^[2].

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

Animal Model:	Three-week old female Chinese Kunming mice (12–14 g body weight) were infected intraperitoneally with JEV^[2]
Dosage:	50, 75 or 100 mg/kg/day
Administration:	Administered intragastrically by gavage
Result:	50 mg/kg/day, 75 mg/kg/day and 100 mg/kg/day led to 30%, 70% and 90% mice survival, respectively.

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: ≥ 3.25 mg/mL (10.58 mM); Clear solution

This protocol yields a clear solution of ≥ 3.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (32.5 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.
