专利号:WO-2024057083-A1 优先权日:2022-11-28 标 题 :Process for the synthesis of selectively alkylated cyclodextrins 发明人:IVÃ?NYI RÓBERT; TUZA KATA; SZENTE LAJOS; PUSKÃ?S ISTVÃ?N; SZÅ?CS LEVENTE; KURKAYEV ABDULA 权利人:CYCLOLAB CYCLODEXTRIN R&D LABORATORY LTD 摘要:The present invention generally relates to a process for the synthesis of selectively alkylated cyclodextrins. More particularly, the present invention relates to a process of cyclodextrin alkylation in a selective manner yielding hexakis(2,6-di-O-alkyl)-alpha-cyclodextrin, heptakis(2,6-di-O-alkyl)-beta-cyclodextrin and octakis(2,6-di-O-alkyl)-gamma-cyclodextrin.
专利号:US-7309591-B2 优先权日:2002-01-24 标 题:Method for the production of resveratrol in cell cultures 发明人:BRU MARTINEZ ROQUE; PEDRENO GARCIA MARIA DEL LOS A 权利人:UNIV ALICANTE 摘要:The invention relates to a method for the production of resveratrol in cell cultures. The inventive method consists in: incubating a culture of cells which produce resveratrol naturally, in suspension, in the presence of randomly-methylated β-cyclodextrin (RMBCD) with a degree of substitution of between 11 and 13 under conditions that allow resveratrol synthesis and the excretion of same into the culture medium; and, if desired, isolating the resveratrol produced from said culture medium. The resveratrol can be used in the production of pharmaceutical or nutraceutical products.

专利号:US-5403898-A 优先权日:1992-05-04 标 题:Single arm attached cyclodextrin polysiloxanes and use thereof as chiral stationary phases in chromatographic separation of enantiomers 发明人:BRADSHAW JERALD S; LEE MILTON L; ROSSITER BRYANT E 权利人:UNIV BRIGHAM YOUNG 摘要:Cyclodextrin containing polymeric siloxanes wherein the cyclodextrin is connected to the polymeric siloxane by a single linking member connected to the 2, 3 or 6-position of the cyclodextrin are disclosed. These polymers are chemically and thermally stable to gas, supercritical fluid chromatographic conditions. The single arm attachment provides cyclodextrin containing polysiloxane polymers having synthesis reproducibility from batch to batch resulting in consistent chromatographic performance of the resulting chiral phases. The use of such polymers as chiral stationary phases in analytical and preparative gas, supercritical fluid and liquid chromatographic separations, and particularly for analysis of enantiomeric and other stereoisomeric mixtures of various substances is shown.
