Biochem/physiol Actions

Niclosamide uncouples oxidative phosphorylation in the tapeworm and inhibits mitochondrial oxidative phosphorylation of parasitic helminths. It blocks tumor necrosis factor-induced IκBα phosphorylation, translocation of p65, and expression of NF-κΒ– regulated genes in AML cells.

Application

Niclosamide is a teniacide in the anthelmintic family. It is effective against cestodes that infect humans. Niclosamide is used to study the Wnt/Frizzled-1 signaling pathway. It is used to inhibit transcription and DNA binding of the NF-?B pathway and it increases ROS levels to induce apoptosis in acute myelogenous leukemia (AML) cells.

Viruses use a limited set of host pathways for infection. These pathways represent bona fide antiviral targets with low likelihood of viral resistance. We identified the salicylanilide niclosamide as a broad range antiviral agent targeting acidified endosomes. Niclosamide is approved

A recent hypothesis for cancer chemoresistance posits that cytotoxic survival of a subpopulation of tumor progenitors drives the propagation of recurrent disease, underscoring the need for new therapeutics that target such primitive cells. To discover such novel compounds active against

The microenvironment of breast cancer comprises predominantly of adipocytes. Adipocytes drive cancer progression through the secretion adipocytokines. Adipocytes induce epithelial mesenchymal transition of breast cancer cells through paracrine IL-6/Stat3 signalling. Treatment approaches that can target adipocytes in the microenvironment and
