背景

Niclosamide is an inhibitor of the signal transducer and activator of transcription 3 (STAT3) with IC50 value of 0.7 μM [1].

STATs are a class of transcription factors that regulate fundamental cellular and biological processes, such as cell proliferation, cell survival, immune responses, and angiogenesis, by modulating the expression of specific target genes. STAT3 has been frequently reported to be over-activated in various human cancer types [1].

In HeLa cells, Niclosamide (< 5 μM) inhibited STAT3-mediated luciferase reporter activity with in a dose dependent manner, with IC50 value of 0.25 μM. In Du145 cancer cells, Niclosamide(< 10 μM) dose-dependently induced G0/G1 arrest and apoptosis [1].

In nude mice bearing HL-60 xenograft tumors, Niclosamide treatment (40 mg/kg/d, i.p.) for 15 days potently inhibited the growth of HL-60 tumors. Further, immunoblotting of xenograft tissues from mice revealed a potent inhibitory effect of Niclosamide on the pathway of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) [2].

试验操作

Cell experiment:[1]

Cell lines

Du145 prostate cancer cells

Reaction Conditions

0 ~ 10 μM niclosamide for 24 h incubation

Applications

Niclosamide (≤ 2 μM) dose-dependently inhibited the Tyr-705 phosphorylation of STAT3 and the transcription of STAT3 downstream genes in Du145 cells. In addition, niclosamide induced G0/G1 arrest (≤ 1 μM) and apoptosis of Du145 cells (≤ 10 μM) in a dose dependent manner.

Animal experiment:[2]

Animal models

Nude mice bearing HL-60 xenograft tumors

Dosage form

40 mg/kg/d

Injected intraperitoneally (i.p.) for 15 days

Applications

In nude mice bearing HL-60 xenograft tumors, niclosamide treatment (40 mg/kg/d, i.p.) for 15 days potently inhibited the growth of HL-60 tumors. Further, immunoblotting of xenograft tissues from mice revealed a potent inhibitory effect of niclosamide on the NF-κB pathway.
