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.

标题:Synthesis of equol
发明人：STEFFAN BERT
权利人:STEFFAN BERT
摘要:Subject of the invention is a method for the production of isoflavanes from isoflavones, whereby in a first reaction step (a) the 4-keto group of the isoflavone is reduced in a enantioselective manner, whilst the 2,3-double bond is maintained, to the 4-hydroxy compound.

标 题:Droplet polymerization method for synthesis of molecularly imprinted polymers
发明人：NORTON TUCKER
权利人:DU PONT
摘要:A droplet polymerization process is provided to create efficacious molecularly imprinted polymers (MIPs). Such imprinted polymers have increased surface area for adsorptive or catalytic reactions. This method provides for monomer-template interactions in the absence of a suspending medium, thereby permitting formation of MIPs with increased template selectivity and substantial processing advantages. The process is particularly useful for separating isoflavones from soy whey.

发明人：MCGONIGLE BRIAN
权利人:DU PONT
摘要:An isolated nucleic acid fragment encoding a chalcone isomerase is disclosed. Also of concern is the synthesis of a recombinant DNA construct encoding all or a portion of the chalcone isomerase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the chalcone isomerase in a transformed host cell.
