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.

Following regioselective protection of the estrogen receptor downregulator fulvestrant (ICI 182,780) 1 as its 17-acetate 2 or 3-benzoate 4, the 3-sulfate 5 and 3- and 17-glucuronide conjugates 8 and 12 were prepared. Satisfactory preparation of 12 required use of the tri-O-isobutyryl imidate derivative 10 in conjunction with an inverse-addition technique not previously employed in glucuronidation. The value of this method for simpler aglycones is discussed together with a study of variations in donor acyl substituent and catalyst. Another putative metabolite, the 17-ketone 19, was prepared by direct oxidation of 1.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal

Several ruthenium and rhodium complexes including 2,2-dipyridylamine ligands substituted at the central N atom by an alkyl chain terminated by a maleimide functional group were tested along with a newly synthesized Rh(III) complex of unsubstituted 2,2-dipyridylamine as catalysts in the transfer hydrogenation of aryl ketones in neat water with formate as hydrogen donor. All of them except one led to the secondary alcohol products with conversion rates depending on the metal complex. Site-specific anchoring of the N-maleimide complexes to the single free cysteine residue of the cysteine endoproteinase papain endowed this protein with transfer hydrogenase properties towards 2,2,2-trifluoroacetophenone. Quantitative conversions were reached with the Rh-based biocatalysts, while modest enantioselectivities were obtained in certain reactional conditions.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6.

Lectin from the seeds of Dioclea lasiophylla (DlyL) was purified in a single step by affinity chromatography on a Sephadex G-50 column. DlyL strongly agglutinated rabbit erythrocytes and was inhibited by monosaccharides (D-mannose and alpha-methyl-Dmannoside) and glycoproteins (ovalbumin and fetuin). Similar to other Diocleinae lectins, DlyL has three chains, alpha, beta and gamma, with mass of 25,569 ¡À 2, 12,998 ¡À 1 and 12,588 ¡À 1 Da, respectively, and has no disulfide bonds. The hemagglutinating activity of DlyL was optimal in pH 8.0, stable at a temperature of 70 C and decreased in EDTA solution, indicating that lectin activity is dependent on divalent metals. DlyL exhibited low toxicity on Artemia sp. nauplii, but this effect was dependent on the concentration of lectin in solution. DlyL immobilized on cyanogen bromide-activated Sepharose 4B bound 0.917 mg of ovalbumin per cycle, showing the ability to become a tool for glycoproteomics studies.

Protein arginine methyltransferases (PRMTs) play an important role in diverse biological processes. Among the nine known human PRMTs, PRMT3 has been implicated in ribosomal biosynthesis via asymmetric dimethylation of the 40S ribosomal protein S2 and in cancer via interaction with the DAL-1 tumor suppressor protein. However, few selective inhibitors of PRMTs have been discovered. We recently disclosed the first selective PRMT3 inhibitor, which occupies a novel allosteric binding site and is noncompetitive with both the peptide substrate and cofactor. Here we report comprehensive structure-activity relationship studies of this series, which resulted in the discovery of multiple PRMT3 inhibitors with submicromolar potencies. An X-ray crystal structure of compound 14u in complex with PRMT3 confirmed that this inhibitor occupied the same allosteric binding site as our initial lead compound. These studies provide the first experimental evidence that potent and selective inhibitors can be created by exploiting the allosteric binding site of PRMT3.

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.

Methyl (2E,4E?)-5-(2?,3?,4?,6?-tetra-O-acetyl-p-D- glucopyranosyloxy)penta-2,4-dienoate 16a, assembled by a Wittig condensation of tributyl(methoxycarbonylmethylene)phosphorane 19a and (2E)-3-(2?,3?,4?,6?-tetra-O-acetyl-?- Dglucopyranosyloxy)propenal 20, displays excellent Re-face reactivity towards diethyl azodicarboxylate 15a, bis(2,2,2trichloroethyl) azodicarboxylate 15b, dibenzyl azodicarboxylate 15c, diisopropyl azodicarboxylate 15d and di-tertbutyl azodicarboxylate 15e in thermal hetero-Diels-Alder reactions to give the cycloadducts 17a-e. When subjected to the action of hydrogen over palladium-carbon, the cycloadducts 17a, 17b, 17d and 17e undergo hydrogenation of their olefinic bonds to give the dihydro derivatives 18a, 18b, 18d and 18e; in the case of the cycloadduct 17c, hydrogenolysis of the benzyloxycarbonyl group also occurs to give methyl (35)-2,3,4,5-tetrahydropyridazine-3carboxylate Ib with an ee of 98% and 2,3,4,6-tetra-O-acetyl-?-D-glucopyranose 22. Compound Ib, with an ee of 98%, is also available from the dihydro derivative 18e by the action of trifluoroacetic acid; however, under the acidic conditions, a condensation reaction between the aglycone Ib and the glycone 22 competes to give methyl (35)-2,3,4,5tetrahydro-2-(2?,3?,4?,6?-tetra-0-acetyl- ?-D-glucopyranosyl)pyridazine-3-carboxylate25. Sodium (35)-2,3,4,5-tetrahydropyridazine-3-carboxylate le, with an ee of 99%, is available from the ester Ib by a saponification reaction. The trifluoroacetic acid salt 27, with an ee of 95%, is obtained from benzyl (35,6S)1,2-bis(tert-butoxycarbonyl)-1,2,3,6-tetrahydro-6-(2?,3?, 4?,6?-tetra-O-acetyl-beta-D-glucopyranosyIoxy)pyridazine-3- carboxylate 17g by a hydrogenation-trifluoroacetolysis sequence. A hetero-Diels-Alder reaction involving the benzyl pentadienoate 16c and di-tert-butyl azodicarboxylate 15e provides the cycloadduct 17g. The Royal Society of Chemistry 1999.
