标 题:Synthesis of lactone derivatives and their use in the modification of proteins

权利人:GENIE BIOTECH UK LTD
摘要:Site-specific modifications of proteins are desirable in biotechnological applications such as biopharmaceuticals, immunotherapy, vaccines, and are useful in chemical biology. Gluconoylation is a non-enzymatic, covalent, post-translational modification commonly observed on N-terminal His-Tags bearing proteins. We synthesized glucono-1,5-lactone derivatives, including azido variants for selective acylation. High yield acylation is achieved by simply mixing derivatives with target protein amidst diverse conditions of temperatures, aqueous buffers, excipients, or complex cell lysate.

标题 :Preparation and uses of hydrocarbylnitrones
发明人：THERIOT KEVIN J
权利人:ALBEMARLE CORP
摘要:Nitrones are produced by reaction of primary amine with aldehyde or ketone, in the presence of a transition metal-containing oxidation catalyst, and a peroxidic compound. The nitrone can then be reacted with a vinylaromatic compound to produce a 2-hydrocarbyl-5-arylisoxazolidine. Both such reactions can be conducted concurrently by including the vinylaromatic compound in the initial reaction mixture. Hydrogenation of the 2-hydrocarbyl-5-arylisoxazolidine, e.g., using hydrogen and a palladium-carbon catalyst, forms an N-hydrocarbyl-3-aryl-3-hydroxypropylamine. Such reactions enable, inter alia, synthesis of the racemic hydrochloride salt of N-methyl-3-phenyl-3-[4-trifluoromethyl)phenoxy]-propylamine, known generically as fluoxetine hydrochloride, a widely used antidepressant.

标 题 :Reduction by a silane in the presence of zinc catalyst
发明人：JERPHAGNON THOMAS; PASTORI JOEL
权利人:FIRMENICH & CIE
摘要:The present invention relates to the field of organic synthesis. More specifically, it concerns a process for the selective reduction of a C 3 -C 70 substrate containing one or more carbonyl or carboxylic functional groups into the corresponding 5 alcohol diol, or polyalcohol in the presence of a silane and at least one catalyst or pre-catalyst in the form of a zinc complex. The Zinc complex of formula (I) or (II) is also part of the invention.
