专利号:US-8147883-B1 优先权日:1999-09-22 标题:Use of a plant oil product as an agent for increasing the synthesis of skin lipids 发明人:MSIKA PHILIPPE; PICCIRILLI ANTOINE 权利人:MSIKA PHILIPPE; PICCIRILLI ANTOINE; EXPANSCIENCE LAB 摘要:The invention concerns the use of at least a vegetable oil product selected among the group consisting of vegetable oil oleic distillates, vegetable oil unsaponifiable matters, vegetable oil furan lipids and mixtures thereof, as agents for increasing skin lipid synthesis, in particular lipids of the epidermal skin barrier, in or for preparing a composition containing a pharmaceutically or dermatologically acceptable medium. The use enables to prevent and/or treat deterioration of the skin barrier (dry skin, skin subjected to actinic radiation, ichthyosis, acne, xerosis, atopic dermatitis, sensitive skin, chafing and reactive skin, itching and the like).
专利号:US-4024333-A 优先权日:1976-06-22 标 题:Synthesis of daunosamine hydrochloride from a D-mannose starting material 发明人:HORTON DEREK; WECKERLE WOLFGANG F 权利人:US HEALTH EDUCATION & WELFARE 摘要:A method for synthesizing daunosamine hydrochloride from methyl α-D-mannopyranoside. The major features of the preparative route involve the formation of a 2-deoxy-3-keto intermediate, whose oxime is reduced with high stereoselectivity to the D-ribo-3-amino compound, followed by a stereospecific step late in the sequence to introduce the terminal C-methyl group with inversion at C-5, to generate the required L-lyxo stereochemistry. The synthesis procedure affords daunosamine hydrochloride in 40% overall yield, with no chromatographic procedures for isolation being required in any of the steps.
