This Has A 12-Membered Ring With Alternating Si And O Atoms. It Is Identified By Comparison Of Its Infrared Spectrum With A Spectrum Of An Authentic Sample. The Reaction Appears To Proceed By Stepwise Insertion Of O Atoms Into Si-Si Bonds. (C) 2001 Published By Elsevier Science B.V.

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

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:Peptidic compounds, compositions comprising them and uses of said compounds, in particular cosmetic uses
发明人：PESCHARD OLIVIER; DOUCET ANNE; LEROUX RICHARD; MONDON PHILIPPE
权利人:SEDERMA SA
摘要:The peptidic compound comprises at least an aminoacid which is lysine, ornithine, diaminopropionic acid or diaminobutyric acid or a derivative of these aminoacids, on which a carboxylic acid is grafted via a peptidic bound on the nitrogen of the lateral chain, said carboxylic acid comprising a (poly)cycle or (poly)heterocycle. Preferably, the grafted carboxylic acid is an aminoacid or a derivative, in particular selected from, a proline, a hydroxyproline or pyroglutamic acid.The peptidic compound can stimulate the synthesis of the main molecules constituting the extracellular matrix of the skin, especially collagen 1 and 4 and elastin. It can be used for topical cosmetic treatment such as a global anti-aging treatment, or for specific activities, including anti-wrinkles, moisturizing, to improve the mechanical properties of the skin, firmness/tone/elasticity/flexibility, to increase density and volume of the skin, improve skin radiance, for a restructuring effect and/or to fight stretch marks.

标 题:Reversing baldness through cannabinoid receptor activation
发明人：POSTREL RICHARD
权利人:POSTREL RICHARD
摘要:This invention reverses male pattern baldness by shocking dormant hair follicles out of their androgen induced hibernation phase back to the active hair-growing anagenic phase. The invention integrates two functions: 1) It blocks synthesis of compounds holding the follicles in the telogenic/hibernating phase and 2) It stimulates synthesis of compounds animating the hair-growing/anagenic phase in the follicular activity cycle. One preferred embodiment comprises an enzyme inhibitor blocking the conversion of testosterone to dihydrotestosterone (DHT), a flavonoid simultaneously increasing synthesis of prostaglandins alternative to prostaglandin D2, and a selected cannabinoid compound stimulating restore the hair follicle to its normal growth cycle. This novel trimodal therapy restores the hair follicles to their normal cycling processes and maintains these restorative properties so long as this rebalance in maintained.

标 题 :Higher order star polymers having multiple polyisobutylene arms radiating from a condensed core of siloxanes and a method for the synthesis thereof
发明人：KENNEDY JOSEPH P; OMURA NAOKI; LUBNIN ALEXANDER
权利人:UNIV AKRON
摘要:The synthesis and characterization of novel higher order, multi-arm star polymers comprising polyisobutylene arms connected to condensed cyclosiloxane cores are described. The synthesis has been achieved by hydrosilating olefin-capped (e.g., allyl- or isopropenyl-terminated) polyisobutylene with hydrogencyclosiloxanes carrying a plurality of Si-H groups and simultaneously and competitively converting SiH functions, in the presence of moisture, to Si-OH groups to rapidly self-condense or react with SiH groups to form coupled cyclosiloxane cores via core-core coupling. Thus, higher order stars having many more arms than first order stars can be formed.
