Dietary plant components ellagic acid and tannic acid inhibit Escherichiacoli biofilm formation

Ellagic Acid Derivatives from Rubus ulmifolius Inhibit Staphylococcus aureus Biofilm Formation and Improve Response to Antibiotics

BACKGROUND Biofilms contribute to the pathogenesis of many forms of Staphylococcus aureus infection. Treatment of these infections is complicated by intrinsic resistance to conventional antibiotics, thus creating an urgent need for strategies that can be used for the prevention and treatment of biofilm-associated infections. METHODOLOGY/PRINCIPAL FINDINGS This study demonstrates that a botani...

Tannic acid Datasheet

Selective inhibition of methylbenzylnitrosamine-induced formation of esophageal O6-methylguanine by dietary ellagic acid in rats.

Ellagic acid is a naturally occurring plant phenol which has been shown to reduce the incidence of a number of carcinogen-induced tumors including methylbenzylnitrosamine (MBN)-induced esophageal carcinoma in the rat. The postulated mechanism of MBN-induced esophageal carcinogenesis is through oxidation of MBN to form benzaldehyde and an activated metabolite which methylates DNA forming a varie...

The Formation of Ellagic Acid from Galloyl-Glycine by Penicillium.

Kraemer [1900], who investigated the galls formed by Cynips aciculata on Quercus cocinea, found that during the chrysalis stage gallic acid was produced and that as the imago developed the gallic acid gave place to tannic acid. These observations gain in interest if viewed in the light of the recent investigations of v. Stockert and Zellner [1914], who have proved the presence of nitrogenous pr...

Main components of pomegranate, ellagic acid and luteolin, inhibit metastasis of ovarian cancer by down-regulating MMP2 and MMP9

Ovarian cancer is the third most common cancer in the female reproductive organs and epithelial ovarian cancer has the highest lethality of all gynecological cancers. Pomegranate fruit juice (PFJ) has been shown to inhibit the growth of several types of cancer other than ovarian cancer. In this study, we exposed the ovarian cancer cell line A2780 to PFJ and two of its components (ellagic acid a...
