Salinomycin Na | Cancer stem cell inhibitor

Salinomycin Na (55721-31-8) is a polyether ionophore with antibiotic and anti-cancer properties. It induces cell death in some types of cancer cells such as breast, lung, gastric cancer, leukemia and osteosarcoma.1 Salinomycin Na displays selective toxicity for cancer stem cells.1 Induces rapid mitochondrial hyperpolarization.2 Induces selective cytotoxicity to MCF-7 mammosphere cells via the hedgehog signaling pathway.3 Salinomycin Na reduces doxorubicin resistance of breast tumor cells by inhibiting drug efflux pump expression and activity.4 Kills cancer stem cells by sequestering iron.5
