  • Patent number: 8945907
    Abstract: The present invention relates to a microorganism having L-tryptophan productivity and a method for producing L-tryptophan using the same. More precisely, the present invention relates to the recombinant E. coli strain CJ600 (KCCM 10812P) having tryptophan productivity produced from the mutant form (KFCC 10066) of E. coli having L-phenylalanine productivity, wherein tryptophan auxotrophy is released, L-phenylalanine biosynthesis is blocked but tryptophan productivity is enhanced by reinforcing the gene involved in tryptophan biosynthesis, and a method of producing L-tryptophan using the same.

  • Patent number: 8658000
    Abstract: A preparation method of chromenone derivatives using radiation is provided. The preparation method exposes commercially-available silybin in reaction solvent to radiation, to thereby concurrently obtain both dehydrosilybin and apigenin compounds, which are chromenone compounds, in a simple reaction step and with high yield. Because the compounds are prepared at economic cost, the preparation method can be advantageously used particularly for the purpose of mass production. Further, in consideration of good cancer cell viability suppression effect thereof, dehydrosilybin and apigenin prepared according to the preparation method can be advantageously used as a pharmaceutical composition for prevention and treatment of cancer.

  • Publication number: 20090263906
    Abstract: The present invention relates to a method of antioxidative functional estimation using an animal model, more precisely a method of antioxidative functional estimation using mice having oxidative damage caused by reactive oxygen species induced by irradiation and having lipid hydroperoxide secreted in the urine which might be index for quantitative and qualitative analysis for antioxidative functional estimation. The method of antioxidative functional estimation of the present invention can be effectively used for the screening of a novel anti-oxidant agent or antioxidative functional health food to regulate the production of lipid hydroperoxide.
