毒胡蘿卜素產(chǎn)品信息

Thapsigargin (Synonyms: 毒胡蘿卜素)

Thapsigargin，內(nèi)質(zhì)網(wǎng)應(yīng)激誘導(dǎo)劑，是一種微粒體 Ca²⁺-ATPase 抑制劑。Thapsigargin 能有效抑制不同細(xì)胞類(lèi)型的冠狀病毒 (HCoV-229E、MERS-CoV、SARS-CoV-2) 復(fù)制。

生物活性

Thapsigargin, an endoplasmic reticulum (ER) stress inducer, is an inhibitor of microsomal Ca²⁺-ATPase. Thapsigargin efficiently inhibits coronavirus (HCoV-229E, MERS-CoV, SARS-CoV-2) replication in different cell types^[1]^[2]^[3]^[4]^[5].

IC₅₀ & Target

Ca²⁺-ATPase^[1]

體外研究(In Vitro)

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].

Cell Proliferation Assay^[2]

Cell Line:	MH7A human rheumatoid arthritis synovial cells
Concentration:	0.001, 0.1, and 1?μM
Incubation Time:	For 2 and 4 days
Result:	Arrested cell proliferations in a time- and dose-dependent manner.

體內(nèi)研究(In Vivo)

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]

Animal Model:	Male Balb/c mice (20-25 g)^[4]
Dosage:	0.25 ug/g, 0.5 ug/g and 1 ug/g
Administration:	Injection; 24 hours
Result:	Increased of 2 to 5-fold in chemokine and pro-inflammatory expression.
