Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme. Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. 74808-09-6, C36H36Cl3NO6. A document type is Article, introducing its new discovery., Recommanded Product: 74808-09-6

Cyclohexadienone derivatives possessing alpha-D-glucopyranosyl moiety were designed and synthesized using chemical oxidation or electrochemical oxidation with boron-doped diamond electrode in the final stage. In the chiral induction studies, catalytic hydrogenation provided high diastereoselectivity (dr ratio: > 9:1). Conformational analyses of the C-glucoside structures were performed by NOE experiments and force field calculations, and supported the observed regio-selectivity.

The synthesis of Neu5Ac2en mimetics as inhibitors of Vibrio cholerae sialidase is reported. A novel approach to the synthesis of beta-glycosides of N-acetyl-d-glucosaminuronic acid, in six steps and good overall yield from N-acetyl-d-glucosamine, has been developed. The key synthetic step was the Lewis acid mediated O-glycosidation of methyl 1,3,4-tri-O-pivaloyl-N-acetyl-d- glucosaminuronate (11). Elaboration of glucosaminuronides 15 and 18 provided novel sialylmimetics 21 and 22, which showed inhibition of Vibrio cholerae sialidase.

In a Article，once mentioned of 499-40-1

Abstract: A new water-soluble copper(II) complex bearing 4-bromobenzoate/2,2?-dipyridylamine ligands was successfully synthesized and characterized by using single crystal X-ray diffraction and spectroscopic techniques. The catalytic activity of the compound was investigated as a homogeneous catalyst in the oxidation of several alcohols (benzyl alcohol, cinnamyl alcohol, 1-phenylethanol, cyclohexanol, 1-heptanol) and alkenes (styrene, ethylbenzene, cyclohexene) in aqueous medium. The copper(II) catalyst was found to be active for the studied alcohols and alkenes. H 2O 2 was used as an active oxidant for alcohol oxidation, while t-BuOOH (TBHP) was used for alkenes. The compound exhibited high selectivity toward benzaldehyde (88%) in cinnamyl alcohol oxidation under mild conditions (70 ?C) after 4 h. Particularly, remarkable results were obtained for the oxidation of styrene and cyclohexene; transformation via allylic oxidation to 2-cyclohexene-1-one as one product in 2 h (TOF=50h-1) and benzaldehyde in 1 h (100% conversion, TOF = 86 h – 1, 100% selectivity). The Cu(II)/TBHP (or H 2O 2) / H 2O system proved to be an alternative for catalytic oxidations in the green chemistry concept. Graphical Abstract: New Copper(II)-complex bearing 4-bromobenzoate/2,2?-dipyridylamine ligands was synthesized and characterized by single crystal diffraction technique. The complex exhibited good catalytic oxidation activity on alcohols and alkenes in water, a green solvent. [Figure not available: see fulltext.].

The effects of various saccharides on the reaction of cycloinulo- oligosaccharide fructanotransferase with cycloinulohexaose were examined. In addition to beta-D-fructofuranosides and methyl alpha-D-glucopyranoside, D-mannose and L-sorbose were found to be effective acceptors in the reactions, and they enhanced the hydrolytic activity as effectively as methyl alpha-D- glucopyranoside. Hetero-tetrasaccharides were isolated as the major transfer products from both reaction mixtures. The isolates were identified by NMR spectroscopy as beta-inulotriosyl-alpha-D-mannopyranoside and 1-O-beta-inulotriosyl- alpha-L-sorbopyranose. Methyl beta-D-glucopyranoside was slightly effective and methyl alpha-D-mannopyranoside was not effective at all as the acceptor, but these saccharides strongly enhanced the hydrolytic activity. D-Glucosamine inhibited the enzyme activity. (C) 2000 Elsevier Science Ltd.
