生物活性

Niclosamide (BAY2353) is an orally bioavailable chlorinated salicylanilide, with anthelmintic and potential antineoplastic activity. Niclosamide (BAY2353) inhibits STAT3 with IC50 of 0.25 μM in HeLa cells and inhibits DNA replication in a cell-free assay.

体外研究

Niclosamide is an inhibitor of STAT3, inhibiting STAT3-mediated luciferase reporter activity with an IC50 of 0.25 μM in HeLa cells. Niclosamide (1 μM) inhibits the EGF-induced nuclear translocation of STAT3 in Du145 cells. Niclosamide (< 2 μM) dose dependently inhibits the transcription of STAT3 downstream genes in Du145 cells. Niclosamide (< 10 μM) induces G0/G1 arrest and apoptosis of Du145 cancer cells in a dose dependent manner. Niclosamide can block SARS-CoV replication at a micromolar concentration in Vero E6 cells infected with SARS-CoV. Niclosamide (< 7.5 μM) promotes Frizzled1 endocytosis, downregulates Dishevelled-2 protein, and inhibits Wnt3A-stimulated beta-catenin stabilization and LEF/TCF reporter activity in U2OS cells. Niclosamide inhibits the TNF-induced NF-κB reporter activity in a dose- and time-dependent manner in U2OS cells. Niclosamide (125 nM) inhibits NF-κB activation induced by p65, IKKα, IKKβ, IKKγ, and TAK1 in U2OS cells. Niclosamide (< 500 nM) completely block the time- and dose-dependent TNFα-induced alteration of the NF-κB-DNA complex in HL-60 cells. Niclosamide (< 10 nM) inhibits constitutive NF-κB activation in U266 cells. Niclosamide inhibits TNF-induced degradation of IκBα and relocation of p65 in a dose- and time-dependent manner in HL-60, Molm13, or AML primary cells. Niclosamide (500 nM) causes decrease in TNF-induced NF-κB-dependent gene products involved in cell survival in HL-60 cells. Niclosamide also inhibits the growth and induces robust apoptosis of AML cells associated with decreased Mcl-1 and XIAP levels and increased intracellular ROS levels.

体内研究
