Bioactivity | Tizoxanide (TIZ) is the active metabolite of Nitazoxanide, which is a thiazolide anti-infective compound against anaerobic bacteria, protozoa, and a range of viruses. Tizoxanide (TIZ) has anti-HIV-1 activities and potent inhibition of both HBV and HCV replication with values EC50 of 0.46μM and 0.15 μM, respectively. Tizoxanide also exerts anti-inflammatory effects by inhibiting the production of pro-inflammatory cytokines and suppressing of the activation of the NF-κB and the MAPK signaling pathways in LPS-treated macrophage cells[1][3][4][5]. | ||||||||||||

Invitro | Tizoxanide (TIZ) induces mild mitochondrial uncoupling and activate AMPK in hepatocytes[1].Tizoxanide (TIZ) inhibits hepatitis C virus (HCV) replication in HCV replicon systems[3]. Cell Viability Assay[1] Cell Line: | ||||||||||||
In Vivo | Tizoxanide (TIZ) (10 mg/kg; i.v.) can pass the BBB and distribute to the brain tissue. Tizoxanide retains in brain is obviously longer than that in plasma[2]. Animal Model: | ||||||||||||
