Biochem/physiol Actions

Tizoxanide (TIZ) is the active metabolite of the broad-spectrum parasiticidal drug nitazoxanide (NTZ), a noncompetitive inhibitor against bacterial pyruvate-ferredoxin oxidoreductase (PFOR Ki 2 to 10 μM). NTZ deacetylates rapidly to TIZ in plasma (t1/2 ~6 min at 37°C in human plasma) and in the presence of liver microsomes. NTZ is also reported to exhibit antiviral activity against Hepatitis C, Norovirus, Paramyxovirus, Influenza, Vaccinia, and Zika.

The pharmacokinetics of tizoxanide (T), the active metabolite of nitazoxanide (NTZ), and its protein binding ability in goat plasma and in the solutions of albumin and alpha-1-acid-glycoprotein were investigated. The plasma and protein binding samples were analyzed using a high-performance

Nitazoxanide (NTZ) and its metabolite tizoxanide (TIZ) were studied as antimycobacterial agents in vitro (in mycobacterial growth indicator tube [MGIT] cultures) and in a whole blood bactericidal assay. Both NTZ and TIZ show high protein binding. In MGIT cultures (albumin concentration = 78 μM)

Nitazoxanide (N), a new broad-spectrum parasiticidal agent, is rapidly deacetylated to tizoxanide (T). The objective of the study was to determine if metabolites other than T are present in the plasma and excreted after single dose oral administration of radiocarbon-labelled

Antimicrobial agents and chemotherapy, 51(3), 868-876 (2006-12-13)
Nitazoxanide (NTZ) exhibits broad-spectrum activity against anaerobic bacteria and parasites and the ulcer-causing pathogen Helicobacter pylori. Here we show that NTZ is a noncompetitive inhibitor (K(i), 2 to 10 microM) of the pyruvate:ferredoxin/flavodoxin oxidoreductases (PFORs) of Trichomonas vaginalis, Entamoeba histolytica
Jinqiu Liu et al.
Biomedical chromatography : BMC, 30(11), 1744-1749 (2016-04-24)
Nitazoxanide (NTZ) is a broad-spectrum antimicrobial agent. Tizoxanide (T) and tizoxanide glucuronide (TG) are the major circulating metabolites after oral administration of NTZ. A rapid and specific LC-MS/MS method for the simultaneous quantification of T and TG in mouse plasma
