标题:异黄酮糖基化的有效方法
摘要:异黄酮植物雌激素因其正面和负面的健康益处而受到当前的关注.然而,关于它们的吸收,代谢和生物利用度,仍有许多悬而未决的问题.该领域的研究需要获取异黄酮 7-O-葡萄糖苷(在植物中发现的形式)和 7-O-葡萄糖醛酸苷(它们是重要的哺乳动物代谢物)的样本.描述了一种新的高效,高产的异黄酮糖基化程序,它采用 2,2,2-三氟-N-(对甲氧基苯基)乙酰胺作为糖基供体.该方法用于制备三种主要异黄酮,黄豆苷元,染料木黄酮和黄豆黄素的 7-O-糖苷.异黄酮用己酰基保护,这提高了它们在有机溶剂中的溶解度并提高了反应效率.然后采用相同的方法合成类似的 7-O-葡糖苷酸.新的合成将为进一步的生物学研究提供大量这些化合物.(© Wiley-Vch Verlag Gmbh & Co.

摘要:A method for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid derivatives. The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.

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 :Automated methods for scalable, parallelized enzymatic biopolymer synthesis and modification using microfluidic devices
发明人：BANAL JAMES; BERLEANT JOSEPH DON; SHEPHERD TYSON; BATHE MARK
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:Methods for the automated template-free synthesis of user-defined sequence controlled biopolymers using microfluidic devices are described. The methods facilitate simultaneous synthesis of up to thousands of uniquely addressed biopolymers from the controlled movement and combination of regents as fluid droplets using microfluidic and EWOD-based systems. In some forms, biopolymers including nucleic acids, peptides, carbohydrates, and lipids are synthesized from step-wise assembly of building blocks based on a user-defined sequence of droplet movements. In some forms, the methods synthesize uniquely addressed nucleic acids of up to 1,000 nucleotides in length. Methods for adding, removing and changing barcodes on biopolymers are also provided. Biopolymers synthesized according to the methods, and libraries and databases thereof are also described. Modified biopolymers, including chemically modified nucleotides and biopolymers conjugated to other molecules are described.
