Beschreibung

Allgemeine Beschreibung

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.
