Three oxidative metabolites of indole-3-acetic acid from Arabidopsis thaliana

Three metabolites of indole-3-acetic acid (IAA), N-(6-hydroxyindol-3-ylacetyl)-phenylalanine (6-OH-IAA-Phe), N-(6-hydroxyindol-3-ylacetyl)-valine (6-OH-IAA-Val), and 1-O-(2-oxoindol-3-ylacetyl)-beta-d-glucopyranose (OxIAA-Glc), were found by a liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS)-based search for oxidative IAA metabolites during the vegetative growth of Arabidopsis. Their structures were confirmed by making a comparison of chromatographic characteristics and mass spectra between naturally occurring compounds and synthetic standards. An incorporation study using deuterium-labeled compounds showed that 6-OH-IAA-Phe and 6-OH-IAA-Val were biosynthesized from IAA-Phe and IAA-Val, respectively, which strongly suggested the formation of these amino acid conjugates of IAA in plants. Both 6-OH-IAA-Phe and 6-OH-IAA-Val were inactive as auxins, as indicated by no significant root growth inhibition in Arabidopsis. Quantitative analysis demonstrated that OxIAA-Glc was present in the largest amount among the metabolites of IAA in Arabidopsis, suggesting that the conversion into OxIAA-Glc represents the main metabolic process regarding IAA in Arabidopsis.

Nickel-Catalyzed Decarboxylative Alkenylation of Anhydrides with Vinyl Triflates or Halides

Decarboxylative cross-coupling of aliphatic acid anhydrides with vinyl triflates or halides was accomplished via nickel catalysis. This methodology works well with a broad array of substrates and features abundant functional group tolerance. Notably, our approach addresses the issue of safe and environmental installation of methyl or ethyl group into molecular scaffolds. The method possesses high chemoselectivity toward alkyl groups when aliphatic/aromatic mixed anhydrides are involved. Furthermore, diverse ketones could be modified with our strategy.

Dye-sensitized photooxygenation of 2,5-Bis(glycosyl)furans

The dye-sensitized photooxygenation of 2,5-bis(glycosyl)furans followed by warming up to r.t. provides 1,1′- linked disaccharides separated by a functionalized spacer. Asymmetrical disubstituted glycosyl furans give the corresponding Bayer-Villiger type-rearranged products in a molar ratio depending on the sugars and the protecting groups. The migratory aptitudes have been rationalized by both theoretical calculations and experimental data. The 1,1′- disaccharides obtained are new sugar derivatives structurally related to some mimetics of Sialyl Lewis X.

Glycosylidene Carbenes, Part 9: Regioselective Glycosidation of Diols and Triols: Intra- and Intermolecular Hydrogen Bonds

Glycosidation of the myo-inositol derivatives 2 and 3 by the diazirine 1 yields 90percent of a diastereoisomer pair of beta-D-glycosides in a 1:1 ratio, i.e. 5/6 and 7/8, respectively (Scheme 1).The crystal structure of 3 shows a strong intramolecular H-bond, which persists in solution, as indicated by FT-IR and 1H-NMR spectra.Yields and diastereoselectivity are lower for the glycosidation of 24 by 1 (Scheme 3).The resulting 1,2- and 1,4-linked disaccharides 25-28 were isolated as their acetates 29-32.The previously determined crystal structure of 24 shows no intramolecular H-bonds.The yield of the glycosidation of 24, but not of 3, depends upon the concentration, indicating that activation of 24 by intermolecular H-bonds is required.Glycosidation of 2 and 3 with the trichloroacetimidate 14 gave mixtures of four (5, 6, 15, and 16), and six (7, 8, and 17-20) disaccharides, respectively (Scheme 2).

Carbohydrate binding specificity of the recombinant chitin-binding domain of human macrophage chitinase.

The chitin-binding domain of human macrophage chitinase was expressed as a fusion protein with glutathione S-transferase in Escherichia coli and assayed for its binding activity. The purified recombinant chitin-binding domain bound to chitin, but not to glucan, xylan, or mannan. The binding of the recombinant chitin-binding domain to chitin was inhibited by N-acetylglucosamine, di-N-acetylchitobiose, and hyaluronan, but not by N-acetylgalactosamine or chondroitin. Furthermore, a solid-phase binding assay showed that the recombinant domain interacts specifically with hyaluronan and hybrid-type N-linked oligosaccharide chains on glycoproteins, and that the oligosaccharide-binding characteristics are similar to those of wheat germ agglutinin, a lectin that binds to chitin. The results suggest that human chitinase chitin-binding domain may be involved in tissue remodeling through binding to polysaccharides or extracellular matrix glycoproteins, and this recombinant protein can be used to elucidate biological functions of the enzyme.
