Cell experiment [1,2]:

Cell lines

NG115-401L neural cell line, isolated rat hepatocytes

Preparation method

The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

ED50: ~20 nM (NG115-401L neural cell line); ED50 ~80 nM (isolated rat hepatocytes)


Thapsigargin stimulated a rapid (within 15 s) transient increase in intracellular [Ca2+] in the NG115-401L neural cell line with the ED50 of around 20 nM. In isolated rat hepatocytes, Thapsigargin increased [Ca2+] in a rapid and dose-dependent manner, with an ED50 value of ~80 nM.

Animal experiment [3]:

Animal models

Male C57BL/6 mice with transient middle cerebral artery occlusion (tMCAO)

Dosage form

IC50: 2 to 20 ng, icv injection


Thapsigargin dose-dependently reduced the brain infarct. Thapsigargin (TG) protected mice against ischemia-reperfusion-induced brain injury.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
