标题 :Methods and compositions for enhancing collagen and proteoglycan synthesis in the skin
发明人：NIMNI MARCEL; HAN BO
权利人:NIMNI MARCEL; HAN BO
摘要:A composition for application to the skin can stimulate the in vivo synthesis of collagen and proteoglycans and improve the appearance of the skin, increasing its elasticity and fullness. In general, a composition according to the present invention comprises: (1) an antioxidant compound in a quantity sufficient to enhance collagen synthesis in the skin; (2) an organic penetrant in which the antioxidant compound is soluble in a sufficient quantity that a concentration of the antioxidant compound sufficient to enhance collagen synthesis can be applied topically and penetrate the skin; (3) a mixture of essential amino acids; (4) a supplemental source of sulfur; and (5) a topical pharmaceutically acceptable carrier. The antioxidant compound can be lipoic acid, a lipoic acid analogue or derivative, a bioflavonoid, a constituent of ginkgo, or an isoflavone. The organic penetrant is preferably benzyl alcohol. Other ingredients, such as esters of tocopherol and ascorbic acid, can be included.

摘要:Lactone-rings of ginkgolides are converted into the corresponding tetrahydrofuran moieties via DIBAL-H reduction followed by deoxygenation of the formed lactols with Et 3 SiH/BF 3 Et 2 O producing a series of lactol-free ginkgolides. The present invention also relates to synthesis of hydroxyl-free, or hydroxyl-free and lactone-free, ginkgolides and bilobalides.
