摘要
The naturally occurring gallotannin beta -D-pentagalloylglucose (beta -PGG) decreases tumor necrosis factor-alpha (TNF-alpha) output from human peripheral blood mononucleocytes exposed to lipopolysaccharide (LPS) by as much as 90% (vs control) at similar to 5 muM concentration. A qualitatively similar but less pronounced effect (similar to 50% decrease) was observed in the serum of rats dosed with both LPS and beta -PGG. These results may have relevance to therapies that target disease states characterized by an overproduction of TNF-alpha. (C) 2001 Elsevier Science Ltd. All rights reserved.
