TIZOXANIDE

Description

Tizoxanide is an active metabolite of the antiparasitic nitazoxanide . Tizoxanide is formed from nitazoxanide via deacetylation of nitazoxanide in the stomach. It is active against M. tuberculosis (MIC = 16 μg/ml). It also reduces the growth of the disease-causing parasites L. mexicana and T. cruzi in vitro (IC₅₀s = 6.2 and 17.5 μM, respectively), inhibits influenza A replication (EC₅₀s = 0.3-1 μM), and inhibits hepatitis B and hepatitis C virus replication (EC₅₀ = 0.15 μM for both).

Definition

ChEBI: Desacetyl-nitazoxanide is a member of salicylamides.

in vitro

previous study found that tizoxanide showed potent inhibition of both hbv and hcv replication. tizoxanide also exhibited selective inhibition of intracellular hbv replication and extracellular virus production by 2.2.15 cells. tizoxanide could selectively reduce intracellular hcv replication in ava5 cells. moreover, the combination of tizoxanide with either recombinant human interferon alpha 2b (ifnα), or an ns5b (hcv polymerase) inhibitor, 2′-c-methyl cytidine, resulted in synergistic interactions against hcv replication. in addition, antiviral activities of tizoxanide against a full-length genotype 1a replicon were equivalent to that observed for ava5 cells [1].

in vivo

animal study in an immunosuppressed rat model suggested that relapses were less frequent after treatment with nitazoxanide, the parent drug of tizoxanide, than with the non-absorbable sinefungin and paromomycin [2].
