专利号:US-8257754-B2 优先权日:2002-10-21 标 题:Synergistic compositions that treat or inhibit pathological conditions associated with inflammatory response 发明人:TRIPP MATTHEW L; BABISH JOHN G; BLAND JEFFREY S; DARLAND GARY K; LERMAN ROBERT; LUKACZER DANIEL O; LISKA DEANN J; HOWELL TERRENCE M 权利人:TRIPP MATTHEW L; BABISH JOHN G; BLAND JEFFREY S; DARLAND GARY K; LERMAN ROBERT; LUKACZER DANIEL O; LISKA DEANN J; HOWELL TERRENCE M; METAPROTEOMICS LLC 摘要:A natural formulation of compounds that would to modulate inflammation is disclosed. The formulation would also inhibit expression of COX-2, inhibit synthesis of prostaglandins selectively in target cells, and inhibit inflammatory response selectively in target cells. The compositions containing at least one fraction isolated or derived from hops. Other embodiments relate to combinations of components, including at least one fraction isolated or derived from hops, tryptanthrin and conjugates thereof, rosemary, an extract or compound derived from rosemary, a triterpene species, or a diterpene lactone or derivatives or conjugates thereof.
