Description:

WARNING: This product is for research use only, not for human or veterinary use.

Emodin (from Rheum emodi, a Himalayan rhubarb) is a purgative resin, 6-methyl-1,3,8-trihydroxyanthraquinone, from rhubarb, buckthorn and Japanese knotweed (Fallopia japonica syn. Polygonum cuspidatum). Emodin is being studied as a potential agent that could reduce the impact of type 2 diabetes. It is a potent selective inhibitor of the enzyme 11β-HSD1. In studies in obese mice, emodin limits the effect of glucocorticoids and may therefore ameliorate diabetes and insulin resistance. Emodin is also shown to block cytomegalovirus infections as well as herpes simplex.

Biological target:
Emodin (Frangula emodin), an anthraquinone derivative, is an anti-SARS-CoV compound.
In vitro activity:
Data showed the alleviative effect of emodin on HG-induced oxidative stress, inflammation and extracellular matrix (ECM) accumulation in SV-MES13 cells. Circ_0000064 was an importantly downstream effector of emodin function in HG-induced SV40-MES13 cells. Reference: J Recept Signal Transduct Res. 2021 Jun 21:1-11. https://pubmed.ncbi.nlm.nih.gov/34151713/
In vivo activity:
Compared with the Sham group, the number of apoptotic cells was significantly higher in the SAP group (Fig. 2A and B). However, emodin and DEX treatment significantly decreased the number of apoptotic cells compared with the SAP group (Fig. 2A and B). In addition, the expression levels of caspase-3, Bax and Bcl2 were evaluated. Western blotting results revealed significantly increased expression levels of cleaved caspase-3 and Bax, but a significant decrease in Bcl-2 expression in the SAP group compared with in the Sham group (Figs. 2C-F and S1). However, in emodin- and DEX-treated rats, these changes were significantly reversed (Figs. 2C-F and S1).
