1. Antitumor activity of irinotecan with ellagic acid in C6 glioma cells
SUMMARY OBJECTIVE: Irinotecan-based combination chemotherapies in malignant gliomas need to be examined. The aim of this study was to investigate the synergetic effect of ellagic acid, a natural polyphenolic antioxidant compound, with irinotecan, an inhibitor of topoisomerase I enzyme, on the growth, cadherin switch, and angiogenic processes of a glioma cel

2. Comparative analysis of enzymatic activity of tannase in non-conventional yeasts to produce ellagic acid
Abstract Non-conventional yeasts represent an alternative for microorganisms that are capable to produce the enzyme Tannase (EC 3.1.1.20), which has many applications is the food and pharmaceutical industry as it stands out for its ability to produce ellagic acid out of the enzymatic hydrolysis of ellagitannins. Ellagic acid has been studied in the medical a

6. Determination of active compounds in raspberry leaf extracts and the effects of extract intake on mice
Abstract Twelve typical polyphenols in raspberry leaf powder (RLP), raspberry leaf extract 1 (RLE) and raspberry leaf extract 2 (RLE-H) were analyzed by HPLC-MS. The sum of their contents in three samples were in the following order: RLP (8.6 mg g-1) < RLE (35.0 mg g-1) < RLE-H (44.1 mg g-1). Ellagic acid and quercetin-3-O-glucuronide were the principal comp

10. Inhibitory Effects of Some Flavonoids on Thioredoxin Reductase Purified from Chicken Liver
ABSTRACT Thioredoxin reductases (TrxRs) are selenocysteine-containing flavoenzymes that reduce Trxin NADPH-dependent manner. In the view of the direct vital role of TrxR in a wide range of biochemical and physiological processes, methods to inhibit this enzyme are clinically important. TrxR has recently emerged as a new candidate in anticancer drug investiga
