标题:The Substrate Specificity Of Tocopherol Cyclase
摘要:The Substrate Specificity Of The Enzyme Tocopherol Cyclase From The Blue-Green Algae Anabaena Variabilis (Cyanobacteria) Was Investigated With 11 Substrate Analogues Revealing The Significance Of Three Major Recognition Sites: (I) The Oh Group At C(1) Of The Hydroquinone,(II) The (E) Configuration Of The Double Bond,And (III) The Length Of The Lipophilic Side Chain. Experiments With Two Affinity Matrices Suggest That Substrates Approach The Enzyme'S Active Site With The Hydrophobic Tail. Copyright (C) 1996 Elsevier Science Ltd

权利人:CARDAX PHARMACEUTICALS INC
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 :Chemicals and use of hypohalites in mechanism-based selective dual radical organic synthesis
发明人：PALOMINO EDUARDO
权利人:WALKER CANCER RES INSTITUTE INC
摘要:The synthesis of pattern-specific compounds using hypohalites, such as hypochlorous acid, sodium hypochlorite, and potassium hypoiodite, as dual-radical generators is provided. The synthesis can be implemented by a cyclization reaction, a dehydrogenation reaction, a hydroxylation reaction, a decarboxylation reaction, or any combination of the above four. The reactions are typically carried out in water, in a nonpolar solvent such as ethyl acetate, or a mixture of both. Hypochlorous acid is made by adding a weak acid such as acetic acid to sodium hypochlorite.

标 题:Formation of chiral 4-chromanones using chiral pyrrolidines in the presence of acids
发明人：MEDLOCK JONATHAN ALAN; LETINOIS ULLA; NETSCHER THOMAS; BONRATH WERNER
权利人:DSM IP ASSETS BV
摘要:The present invention relates to a synthesis of chromanones or chromanes in a stereospecific matter in view of the 2-position in the chromanone or chromane ring. It has been found that this synthesis is particularly possible in the presence of a chiral compound of a specific type and of at least one Bransted acid or in the presence a specific chiral compound having a Bransted acid functional group in the molecule.

发明人：ALKON DANIEL L
权利人:ALKON DANIEL L; BRNI NEUROSCIENCES INST
摘要:The present invention provides methods of contacting a protein kinase C (PKC) activator with a PKC activator in a manner sufficient to stimulate the synthesis of proteins sufficient to consolidate long-term memory. The present invention also provides methods of contacting a protein kinase C (PKC) activator with a PKC activator in a manner sufficient to downregulate PKC.
