Inhibition of 5α-Reductase and Aromatase by the Ellagitannins Oenothein A and Oenothein B fromEpilobiumSpecies

Planta Medica, 1997
Species of the genus Epilobium (Onagraceae) have been investigated for their activity against 5 alpha-reductase and aromatase, two enzymes which are involved in the aetiology of benign prostatic hyperplasia (BPH). Activity-guided fractionation has led to the identification of two macrocyclic ellagitannins, oenothein A (1) and oenothein B (2), as the ...

Oenothein B's Contribution to the Anti-Inflammatory and Antioxidant Activity of Epilobium sp

Phytomedicine, 2011
Willow herb tea or preparation are available and relatively popular in the European market, and claimed to be effective inter alia because of their anti-inflammatory activity. The present study is therefore aimed at comparing the anti-inflammatory and antioxidant activity of extracts of the three most popular Epilobium species (E.

Stimulation and priming of innate lymphocytes by oenothein B (89.59)

The Journal of Immunology, 2010
Abstract Oenothein B is an immunomodulatory tannin isolated from the Epilobium angustifolium plant. This compound is known to affect myeloid cells and these effects include enhanced chemotaxis, NF-κB activation, and production of proinflammatory cytokines, including TNFα and IL-6. Its effects on other innate immune cells have not been

Oenothein B, dimeric hydrolysable tannin inhibiting HCV invasion from Oenothera erythrosepala

Journal of Natural Medicines, 2018
The envelope proteins of the hepatitis C virus (HCV), E1 and E2, have been revealed to be essential for invasion of HCV. Thus, we were engaged in the search for the inhibitors against HCV invasion through the assay system using the model virus expressing recombinant HCV envelopes, E1 and E2. Now, we disclosed dimeric hydrolysable tannin oenothein B (1)
