生物活性 for Thapsigargin
Thapsigargin is a potent inhibitor of sarco/endoplasmic reticulum Ca2+-ATPases (SERCA) that causes endoplasmic reticulum (ER) stress. Thapsigargin can be used to induce autophagy in mammalian cells. In vitro, thapsigargin blocks infection of immortilized and primary human cells with respiratory syncytial virus (RSV), SARS-CoV-2 and influenza A. Thapsigargin protects mice against lethal influenza A viral infection and reduces virus titres in the lungs of treated mice.

Cytosolic Ca2+ sensitive indicator, Fura-2 was loaded in RBL-2H3 cells and excited alternately at 340 and 380 nm and fluorescence was captured at 510 nm.ER store was depleted with 500 nM thapsigargin which promotes store-operated Ca2+ entry via STIM1/Orai1 pathway into the cells upon addition of 2 mM extracellular Ca2+.RBL-2H3 cells were loaded with FURA-2AM (2 μM) and Pluronic F127 (0.02%) for 30 min followed by washing with normal-Tyrode solution. Cells were stimulated at 1 Hz frequency and fluorescence intensities were measured.
