一般描述

A cell-permeable salicylanilide that, in addition to its well-known antihelmintic efficacy, acts as a mammalian mTORC1, but not mTORC2, signaling inhibitor mechanistically distinct from rapamycin. Likely a direct consequence of autophagy activation, Niclosamide is demonstrated to induce Wnt-independent Frizzled1 and Dishevelled-2 downregulation. Unrelated to its autophagy induction activity, Niclosamide is also shown to inhibit Stat3 signaling (IC50= 0.25 M in HeLa reporter assays). Efficiently inhibits breast cancer stem-like cellsin vitroandin vivo.
A cell-permeable salicylanilide that, in addition to its well-known antihelmintic efficacy and use in tapeworm treatment, acts as a mammalian mTORC1, but not mTORC2, signaling inhibitor mechanistically distinct from rapamycin, causing MCF-7 autophagy activation under nutrient-rich conditions (by 15-fold with 4h 10 M treatment), SH-SY5Y lysosome redistribution (10 M for 8 h), and dissipation/clearance of ubiquinated protein aggregates upon proteasome inhibition in a reversible, time- and dose-dependent manner. Likely a direct consequence of autophagy activation, Niclosamide is demonstrated to induce Wnt-independent Frizzled1 endocytosis (t1/2= 2.4 h; effective conc. <2 M) and Dishevelled-2 downregulation (IC50~1 M), effectively preventing Wnt3a from stimulating HEK293 cellular LEF/TCF transcription activity (IC50= 0.5 M TOPFlash reporter assays). Unrelated to its autophagy induction activity, Niclosamide is also shown to inhibit Stat3 signaling (IC50= 0.25 M in HeLa-based pLucTKS3 reporter assays) by suppressing the phosphorylation of Jak1 Tyr1022/1023 (2 h treatment at 0.5 to 2.0 M in Du145 cultures) and Stat3 Tyr705 (by >90% after 24 h treatment at 2 and 5 M, respectively, in Du145 and HeLa cultures), without affecting the phosphorylation of Stat1 Tyr701, Stat3 Ser727, Stat5 Tyr694, or Jak2 Tyr1007/1008.
