InSolution Thapsigargin - CAS 67526-95-8 - Calbiochem

General description

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. Activates apoptosis in rat thymocytes and induces apoptosis in human hepatoma cells.Specifically inhibits the fusion of autophagosomes with lysosomes, and induces autophagy.
