Cat. No.: HY-B0217 Purity: 99.95%
COA Handling Instructions

Nitazoxanide (NTZ), an anthelmintic agent, exhibits a broad spectrum of activities against a wide variety of helminths, protozoa, and enteric bacteria infecting animals and humans. Nitazoxanide inhibits Giardia lamblia trophozoite proliferation in axenic culture with an IC50 of 2.4 μM. Nitazoxanide can be used for the research of parasitic gastroenteritis. Nitazoxanide shows anti-Japanese encephalitis virus (JEV) activity in a mouse model.

    Description

    Nitazoxanide (NTZ), an anthelmintic agent, exhibits a broad spectrum of activities against a wide variety of helminths, protozoa, and enteric bacteria infecting animals and humans. Nitazoxanide inhibits Giardia lamblia trophozoite proliferation in axenic culture with an IC50 of 2.4 μM[1]. Nitazoxanide can be used for the research of parasitic gastroenteritis. Nitazoxanide shows anti-Japanese encephalitis virus (JEV) activity in a mouse model[2].

    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].

    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].

    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.

    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.
