标题:Recombinant strain, construction method therefor, and use thereof in preparation of quillaic acid
发明人：CHOU HOWARD H; YANG JIAZENG
权利人:SHENZHEN INST OF ADV TECH CAS
摘要:Provided are a recombinant strain, a construction method therefor, and a use thereof in the preparation of quillaic acid. In the recombinant strain, a coding sequence of an msbp protein is inserted, said msbp protein being able to promote cytochrome P450 oxidase in the recombinant bacteria to form a complex, and the yield of quillaic acid with cytochrome P450 oxidase participating in synthesis is increased.

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.
