Thapsigargin, anendoplasmic reticulum (ER) stressinducer, is an inhibitor of microsomalCa²⁺-ATPase. Thapsigargin efficiently inhibits coronavirus (HCoV-229E, MERS-CoV, SARS-CoV-2) replication in different cell types^{[1][2][3][4][5]}.

Ca²⁺-ATPase^[1]

Thapsigargin (0.001- 1 μM; for 2 and 4 days) arrests cell proliferations in MH7A human rheumatoid arthritis synovial cells in a time- and dose-dependent manner^[2].
Thapsigargin (0.001- 1 μM; for 2 and 4 days) induces cell apoptosis in MH7A cells in a time- and dose-dependent manner^[2].
Thapsigargin (0.001- 1 μM; for 2 and 4 days) impairs mTOR activity and leads to cyclin D1 expressions in MH7A cells^[2].
Thapsigargin inhibits Ca²⁺entry into human neutrophil granulocytes^[1].
Thapsigargin inhibits the carbachol-evoked [Ca²⁺]i-transients with (IC₅₀=0.353 nM) or without (IC₅₀=0.448 nM) a KCl-prestimulation, but an additional small component, with a much lower sensitivity (IC₅₀=4814 nM), is observed in the absence of a KCl-prestimulation. In contrast, the KCl-evoked [Ca²⁺]i-transients displayed only one component with a very low sensitivity to Thapsigargin in both absence (IC₅₀=3343 nM) and presence (IC₅₀=6858 nM) of a carbachol-prestimulation^[3].
Thapsigargin also phosphorylate p38 MAPK by Ca²⁺influx through SOCE, leading to suppression of TNF-α-induced NF-κB phosphorylation.^[6].

Thapsigargin (Injection; 0.25 ug/g, 0.5 ug/g and 1 ug/g; 24 hours) significant increases of 2 to 5-fold in chemokine and pro-inflammatory expression. Thapsigargin is more sensitive to inducing a systemic immune response^[4].
