Nitazoxanide (Synonyms: 硝唑尼特; NTZ; NSC 697855) 纯度: 98.35%

Nitazoxanide (NTZ) 是一种广谱驱虫剂 (anthelmintic)，对感染动物和人类的各种蠕虫、原生动物和肠道细菌都具有作用活性。 Nitazoxanide 在无菌培养中抑制 Giardia lamblia 滋养体增殖，IC50 为 2.4 μM。Nitazoxanide 可用于寄生虫性 (parasitic) 胃肠炎的研究。Nitazoxanide还具有抗病毒特性。 Nitazoxanide 在小鼠模型中显示出抗日本脑炎病毒 (JEV) 活性。

生物活性

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].

体外研究
(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.

体内研究
(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.
