Physcion
Based on 10 publication(s) in Google Scholar
Physcion (Parietin), an anthraquinone derivative derived from the traditional Chinese medicine rhubarb, is an effective oral active 6-phosphogluconate dehydrogenase inhibitor with blood-brain barrier permeability, with IC50 and Kd values of 38.5 μM and 26.0 μM, respectively. Additionally, Physcion is an inhibitor of the <>bTLR4/NF-κB signaling pathway, exhibiting anti-inflammatory, antibacterial, and anticancer effects, and can induce Apoptosis and Autophagy in cancer cells.

Physcion (10 or 20 μM, 48 h) induces apoptosis and autophagy in human nasopharyngeal carcinoma (CNE2 cells)[2]. Physcion (10-40 μM, 24 h) attenuates OGD/R (oxygen-glucose deprivation/reperfusion)-induced neuronal damage and inflammatory response in SH-SY5Y cells[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

-
Result:Induced apoptosis in CNE2 cells in a dose-dependent manner.
-
Cell Line:The nasopharyngeal carcinoma cell line CNE2
-
Concentration:10 or 20 μM
-
Incubation Time:48 h
-
Result:Significantly increased the level of LC3B-II, which means physcion induced autophagy in CNE2 cells.
-
Cell Line:Oxygen-glucose deprivation/reperfusion (OGD/R)-induced SH-SY5Y cells
-
Concentration:40 μM
-
Incubation Time:24 h
-
Result:Significantly reversed the OGD/R-induced upregulation of TLR4, p-p65, and p-IκB expression.

-
Dosage:20 or 40 mg/kg
-
Administration:Oral gavage (p.o.), once daily for 7 days
-
Result:Significantly reduced the brain water content and the NSS (Neurological Severity Score) in I/R rats, compared to I/R group. Obviously decreased areas of infarction compared to I/R group.
-
Animal Model:SPF chickens (21 days old) infected intra-laryngeally with Chlamydia psittaci 6 BCE[4]
-
Dosage:4 or 9 mg/kg
-
Administration:Oral gavage (p.o.), once daily for 6 days
