A very simple synthesis of GlcNAc-alpha-pyrophosphoryl-decanol: A substrate for the assay of a bacterial galactosyltransferase

Lipid-linked sugar pyrophosphates, such as GlcNAc-pyrophosphoryl undecaprenol, are important intermediates in the biosynthesis of cell-surface bacterial polysaccharides. It was recently demonstrated that much simpler lipids could substitute for undecaprenol while retaining biological activity, thus making efficient synthetic access to this class of compounds highly desirable. In order to facilitate the synthesis of pure substrates for bacterial glycosyltransferases, we have developed a simple ‘two-pot’ synthesis which we demonstrate here for GlcNAc-alpha-pyrophosphoryl-decanol (4). GlcNAc pyrophosphate, produced by mild periodate oxidation/beta-elimination of commercial UDP-GlcNAc, is alkylated using 1-iododecane to yield the target compound 4 in 39% yield. Compound 4 is shown to be an efficient acceptor for a bacterial galactosyltransferase.

Galectin-3-Binding Glycomimetics that Strongly Reduce Bleomycin-Induced Lung Fibrosis and Modulate Intracellular Glycan Recognition

Discovery of glycan-competitive galectin-3-binding compounds that attenuate lung fibrosis in a murine model and that block intracellular galectin-3 accumulation at damaged vesicles, hence revealing galectin-3?glycan interactions involved in fibrosis progression and in intracellular galectin-3 activities, is reported. 3,3?-Bis-(4-aryltriazol-1-yl)thiodigalactosides were synthesized and evaluated as antagonists of galectin-1, -2, -3, and -4 N-terminal, -4 C-terminal, -7 and -8 N-terminal, -9 N-terminal, and -9 C-terminal domains. Compounds displaying low-nanomolar affinities for galectins-1 and -3 were identified in a competitive fluorescence anisotropy assay. X-ray structural analysis of selected compounds in complex with galectin-3, together with galectin-3 mutant binding experiments, revealed that both the aryltriazolyl moieties and fluoro substituents on the compounds are involved in key interactions responsible for exceptional affinities towards galectin-3. The most potent galectin-3 antagonist was demonstrated to act in an assay monitoring galectin-3 accumulation upon amitriptyline-induced vesicle damage, visualizing a biochemically/medically relevant intracellular lectin?carbohydrate binding event and that it can be blocked by a small molecule. The same antagonist administered intratracheally attenuated bleomycin-induced pulmonary fibrosis in a mouse model with a dose/response profile comparing favorably with that of oral administration of the marketed antifibrotic compound pirfenidone.

Selective photoregulation of the activity of glycogen synthase and glycogen phosphorylase, two key enzymes in glycogen metabolism

Glycogen is a polymer of alpha-1,4- and alpha-1,6-linked glucose units that provides a readily available source of energy in living organisms. Glycogen synthase (GS) and glycogen phosphorylase (GP) are the two enzymes that control, respectively, the synthesis and degradation of this polysaccharide and constitute adequate pharmacological targets to modulate cellular glycogen levels, by means of inhibition of their catalytic activity. Here we report on the synthesis and biological evaluation of a selective inhibitor that consists of an azobenzene moiety glycosidically linked to the anomeric carbon of a glucose molecule. In the ground state, the more stable (E)-isomer of the azobenzene glucoside had a slight inhibitory effect on rat muscle GP (RMGP, IC50 = 4.9 mM) and Escherichia coli GS (EcGS, IC50 = 1.6 mM). After irradiation and subsequent conversion to the (Z)-form, the inhibitory potency of the azobenzene glucoside did not significantly change for RMGP (IC50 = 2.4 mM), while its effect on EcGS increased 50-fold (IC50 = 32 muM). Sucrose synthase 4 from potatoes, a glycosyltransferase that does not operate on glycogen, was only slightly inhibited by the (E)-isomer (IC50 = 0.73 mM). These findings could be rationalized on the basis of kinetic and computer-aided docking analysis, which indicated that both isomers of the azobenzene glucoside mimic the EcGS acceptor substrate and exert their inhibitory effect by binding to the glycogen subsite in the active center of the enzyme. The ability to selectively photoregulate the catalytic activity of key enzymes of glycogen metabolism may represent a new approach for the treatment of glycogen metabolism disorders.

Metal complexes catalyzed oxidative coupling of 2,6-dimethylphenol in micellar media

The oxidative coupling reaction of 2,6-dimethylphenol (DMP) with H 2O2 catalyzed by two copper(II) complexes (2,2?-dipyridylamine copper(II), L1Cu and N,N?-bis (2-pyridinecarbonyl) ethylenediamine copper(II), L2Cu) in cationic surfactant cetyl trimethylammonium bromide (CTAB), gemini surfactants ethanediyl-1,2-bis(dodecyldimethylammonium bromide) (12-2-12), dimethylene-1,2-bis(cetyltrimethylammonium bromide) (16-2-16), anionic surfactant sodium dodecyl benzene sulfornate (SDBS) and nonionic surfactant Triton X-100 (TX-100) micellar media were comparatively investigated at 25 C. The kinetics of formation of 3,3?,5,5?-tetramethyl-4, 4?-diphenoquinone (DPQ) was studied. The kinetic parameters k2 and Km were obtained at pH 7.01. L1Cu displayed better catalytic activity than L2Cu in mentioned above systems. For L 1Cu catalyzed systems, the cationic surfactant CTAB, 12-2-12 and 16-2-16 micellar media accelerated the oxidation of DMP. And the TX-100 and SDBS micelles showed little effect on reaction rate compared with the buffer solution. For the L2Cu catalyzed systems, these surfactants all inhibited the oxidation of DMP, and especially, the oxidation of DMP was not found in SDBS micellar solution in the catalyzed system at pH 7.01 and 25 C. Micelles showed great influence on the yield of product and the selectivity of PPO. Under this work’s conditions, DPQ was easily generated in aqueous solution, while PPO was remarkably promoted in micellar media, especially in SDBS micellar solution. As a green technology process, one outstanding advantage of this catalyzed system was that the products of polymer can be easily separated from the solution and the catalysts still remain in the micellar solution.
