A cell-permeable tumor-promoting sesquiterpene lactone that releases Ca2+ by inhibiting endoplasmic reticular Ca2+-ATPase (IC50 = 4-13 nM). Does not increase inositol phosphates and has no significant effect on protein kinase C. Increases Ca2+-dependent Na+ influx in human platelets in a dose-dependent manner. Induces apoptosis in rat thymocytes and in human hepatoma cells. Shown to induce apoptosis in alveolar rhabdomyosarcoma cells by elevating Akt-stimulated PAX3-FOXO1 phosphorylation and promoting its proteasomal degradation.
