Description and Uses

Niclosamide (50-65-7) reversibly inhibits mTORC1 signaling and stimulates autophagy.1 Inhibits activation and nuclear translocation of STAT3 selectively over STAT1 and STAT5. Niclosamide inhibits transcription of STAT3 target genes and induces cell cycle arrest and apoptosis in cells with constitutively active STAT3.2

An inhibitor of the Stat3 signaling pathway and also a FRAP inhibitor.
