Abstract: Disclosed are a composition for reducing beta amyloid-induced neurotoxicity by inhibiting ?-secretase activity, comprising a dibenzofuran derivative, and a method for preparing the same. Further disclosed is that the combination of the dibenzofuran derivative with a ?-secretase inhibitor or an anti-inflammatory agent shows higher activity with respect to reducing beta amyloid-induced neurotoxicity.

Abstract: Disclosed is a composition for treating arthritis containing a dibenzo-p-dioxin derivative as an active ingredient. This dibenzo-p-dioxin derivative is very effective in inhibiting NF-kB and AP-1 activity, alleviates the symptoms of degenerative arthritis and rheumatoid arthritis without irritating the skin or causing side effects, and can continue to exhibit improvement effects for a considerable period of time after discontinuation of treatment. Additionally, when the dibenzo-p-dioxin derivative is contained in liposomes, the composition of the invention exhibits much greater effects on treating arthritis by absorption through skin, and thus is useful for the treatment of degenerative arthritis and rheumatoid arthritis.

Abstract: Disclosed are novel materials separated from Ecklonia cava, a method for extracting and purifying the same, and the use thereof for antioxidants. The method comprises extracting antioxidative ingredients from powdered Ecklonia cava one or more times with an organic solvent; fractionating the antioxidative ingredients one or more times in solvents; and purifying the solvent fractions by chromatography. Superior in scavenging activity and thermal stability, the extract from Ecklonia cava can be used as antioxidants and is suitable in commercialization.

Abstract: Disclosed are whitening cosmetics containing extracts from Ecklonia cava. More specifically, Ecklonia cava which has been dried and crushed into powder, is immersed in a solvent, deposited to extract whitening materials, then, the materials are distilled under reduced pressure to obtain extracts from Ecklonia cava, which are added to whitening cosmetics. The whitening cosmetics containing the extracts from Ecklonia cava of the present invention exhibit excellent whitening effect because of strongly inhibiting tyrosinase activity.

Abstract: This invention relates to a polymer having functional groups at both terminals comprising the steps of: preparing a difunctional initiator by recating divinyl aromatic material and an organo-lithium compound in the presence of a hydrocarbon solvent; synthesizing a random copolymer derived from an aromatic vinyl and conjugated diene monomer at only one terminal of two anionic terminals; adding a polar additive to activate both terminals of said copolymer, followed by the addition of an electrophilic material. The polymer material, so prepared, has an excellent combination of properties such as improved rolling resistance for use in making tire rubber treads, since it can enhance the polymer-filler interaction.

Abstract: This invention relates to a process for preparing a block copolymer composition, wherein it comprises following successive steps:a step in which a vinyl aromatic monomer is polymerized in a reactor in the presence of an inert hydrocarbon solvent and organolithium initiator until depletion of the monomer to generate a living polymer; a step in which a conjugated diene monomer is added to the above polymer to synthesize a living diblock copolymer; a step in which a portion of polymerization terminator is added to partially inactivate the living diblock copolymer; steps in which a conjugated diene monomer and aromatic vinyl monomer are sequentially added to generate a mixture of living triblock copolymer and inactivated diblock copolymer; a step in which a polymerization terminator is added to complete the reaction.
