标题:脂肪酶催化的长链1,2-链烷二醇的立体拆分:优选反应条件的筛选
摘要:开发了可扩展的脂肪酶催化方法,通过酯的立体选择性裂解来动力学拆分长链1,2-链烷二醇对映体.研究了脂肪酶,反应介质,亲核试剂,温度和酰基结构对反应速度,脱酰反应的立体选择性和立体选择性的影响.另外,对于中间体2-单酯,确定了不同酰基的分子内自发迁移的速率.如果使用快速迁移的酰基,则酰基迁移可能会降低两步法的表观立体选择性.发现不同酰基的迁移速率相差最多两个数量级,对于乙酰基和异丁酰基而言更快,而对于丁酰基和苯甲酰基而言则慢得多.

摘要:The present invention relates to the use of tripeptide derivatives for tightening, firming and/or moisturizing skin. Furthermore, the invention relates to a method for stimulating the synthesis of glycosaminoglycans containing a D-glucosamine and/or N-acetyl-D-glucosamine residue and/or proteoglycans by fibroblasts and/or keratinocytes such as in particular the synthesis of Hyaluronic acid and/or of the proteoglycans Decorin and/or Lumican.

标题 :Cosmetic composition for increasing hyaluronic acid synthesis in skin and its use for repairing wrinkles
发明人：PUJOS MURIEL; BERNINI DOROTHEE; ROBERT CECILE; DOUCET OLIVIER
权利人:COTY GERMANY GMBH
摘要:The present invention relates to a skin composition which has an excellent effect on smoothing or repairing wrinkles. The composition comprises Palmitoyl Tripeptide-38 (Palmitoyl-Lysyl-Dioxymethionyl-Lysine) and Piper nigrum (Pepper) seed Extract which combination has been found to result in a synergistic effect on hyaluronan synthase 1 (HAS1) mRNA expression in human fibroblasts. The hyaluronan synthase is responsible for the synthesis of hyaluronan (hyaluronic acid) in skin. Hyaluronic acid is a constituent of the extracellular matrix of the skin and responsible for space filling, tissue repair and retention of moisture.

标 题 :Chemical synthesis of monodisperse and magnetic alloy nanocrystal containing thin films
发明人：MURRAY CHRISTOPHER BRUCE; SUN SHOUHENG; WELLER DIETER K
权利人:IBM
摘要:A method and structure for forming magnetic alloy nanoparticles includes forming a metal salt solution with a reducing agent and stabilizing ligands, introducing an organometallic compound into the metal salt solution to form a mixture, heating the mixture to a temperature between 260° and 300° C., and adding a flocculent to cause the magnetic alloy nanoparticles to precipitate out of the mixture without permanent agglomeration. The deposition of the alkane dispersion of FePt alloy particles, followed by the annealing results in the formation of a shiny FePt nanocrystalline thin film with coercivity ranging from 500 Oe to 6500 Oe.

摘要:Process for the preparation of polyalkylenepolyamines by homogeneously catalyzed alcohol amination, in which aliphatic amino alcohols are reacted with one another or aliphatic diamines or polyamines are reacted with aliphatic diols or polyols with the elimination of water in the presence of a homogeneous catalyst and in the presence of hydrogen gas. Polyalkylenepolyamines obtainable by such processes and polyalkylenepolyamines comprising hydroxy groups, secondary amines or tertiary amines. Uses of such polyalkylenepolyamines as adhesion promoters for printing inks, adhesion promoters in composite films, cohesion promoters for adhesives, crosslinkers/curing agents for resins, primers for paints, wet-adhesion promoters for emulsion paints, complexing agents and flocculating agents, penetration assistants in wood preservation, corrosion inhibitors, immobilizing agents for proteins and enzymes.
