• 溶解性

  アセトニトリルに溶ける。

• 説明

  Thapsigargin is a naturally occurring sesquiterpene lactone isolated from the umbelliferous plant Thapsia garganica. It is a non-competitive, cell permeable inhibitor of calcium transport by SERCAs (IC50 values are cell type-dependent and range from ~2-80 nM). This tumor promoter releases Ca2+ from intracellular stores by specifically inhibiting the endoplasmic reticulum Ca2+-ATPase; it does not directly affect plasma membrane Ca2+-ATPases, Ins 1,4,5-P3 production or protein kinase C activity. This effect is a result of emptying the intracellular calcium stores, which leads to a chain of events that causes apoptosis.

• 化学的特性

  Thapsigargin (TG) is colourless film. It is extracted from the plant Thapsia garganica L. with methanol and purified by HPLC. TG is a tumor promoting plant sesquiterpene lactone extract with a unique biological activity as Ca2+ -ATPase inhibitors in animal cells. It is a skin irritant, a platelet activating, inflammatory and tumor promoting agent. TG is toxic and a possible carcinogen.

• 使用

  THAPSIGARGIN is a widely used inhibitor of the ubiquitous sarco-endoplasmic reticulum Ca(2+)-ATPases in mammalian cells. It acts as a potent, cell-permeable, IP3-independent intracellular calcium releaser that blocks the transient increase in intracellular Ca2+ induced by angiostatin and endostatin. It induces apoptosis by disrupting intracellular free Ca2+ levels.

• 定義

  ChEBI: Thapsigargin is an organic heterotricyclic compound that is a hexa-oxygenated 6,7-guaianolide isolated fron the roots of Thapsia garganica L., Apiaceae. A potent skin irritant, it is used in traditional medicine as a counter-irritant. Thapsigargin inhibits Ca(2+)-transporting ATPase mediated uptake of calcium ions into sarcoplasmic reticulum and is used in experimentation examining the impacts of increasing cytosolic calcium concentrations. It has a role as an EC 3.6.3.8 (Ca(2+)-transporting ATPase) inhibitor and a calcium channel blocker. It is a sesquiterpene lactone, an organic heterotricyclic compound and a butyrate ester.
