Nitazoxanide reduces parasite growth in cell culture by more than 90% with little evidence of drug-associated cytotoxicity.  Nitazoxanide is a new thiazolide antiparasitic agent that shows excellent in vitro activity against a wide variety of protozoa and helminths.  Nitazoxanide and its metabolite tizoxanide are more active in vitro than metronidazole against G. intestinalis, E. histolytica and T. vaginalis.  Nitazoxanide exhibits potent inhibition of both HBV and HCV replication. Nitazoxanide potentiates the effect of subsequent treatment with Nitazoxanide plus IFN, but not Nitazoxanide plus 2'CmeC, in HCV replicon-containing cells. Nitazoxanide induces reductions in several HBV proteins (HBsAg, HBeAg, HBcAg) produced by 2.2.15 cells, but does not affect HBV RNA transcription.  Nitazoxanide exhibits IC50, and IC90 values of 0.017 and 0.776 mg/mL respectively, against E. histolytica, 0.004 and 0.067 mg/mL against G. intestinalis, and 0.034 and 2.046 mg/mL against T. vaginalis. Nitazoxanide is more toxic than metronidazole and albendazole against E. histolytica. 
|In vivo||Nitazoxanide is partially effective at reducing the parasite burden in a gnotobiotic piglet diarrhea model when given orally for 11 days at 250 mg/kg/day but not at 125 mg/kg/day. Nitazoxanide induces a drug-related diarrhea in piglets that might have influenced its therapeutic efficacy. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
