PREPARATION, ISOLATION AND CHARACTERIZATION OF POSITIONAL ISOMERS OF TRIGLUCOPYRANOSYLCYCLOMALTOHEPTAOSE

The positional isomers of triglucopyranosyl-cyclomaltoheptaose (beta-cyclodextrin, betaCD) were chemically synthesized by glucosylation of tris(2,3-di-O-acetyl)-tetrakis(2,3,6-tri-O-acetyl)-betaCDs with 2,3,4,6-tetra-O-benzyl-1-O-trichloroacetoimidoyl-alpha-D-glucopyranose in the presence of trifluoromethanesulfonic acid in dichloromethane, followed by debenzylation and deacetylation.The desired 61,6x,6y-tri-O-(alpha-D-glucopyranosyl)-betaCDs were isolated from each reaction mixture containing their configurational isomers by HPLC and characterized by 13C NMR spectroscopy.

METHODS TO INHIBIT HISTONE ACETYLTRANSFERASE USING GLYCOSAMINOGLYCANS

The present invention is directed to methods for inhibition of histone acetyltransferases using glycosaminoglycans. The invention is further directed to methods for treating disorders associated with hyperacetylation by administration of glycosaminoglycans to a patient in need thereof. In one preferred embodiment, the glycosaminoglycan is a heparin or heparan sulfate oligosaccharide. Studies show that removal of sulfate residues from the O-positions of either the uronic acid or the glucosamine did not eliminate the inhibitory activity of heparan sulfate. Since a majority of heparan sulfate binding proteins appear to require O-sulfation, molecules without certain O-sulfations can be used to inhibit HATs while not interacting with most known heparin-binding proteins. In addition, specific sequences of heparin/heparan sulfate can be used to specifically inhibit various HATs.

Emission Studies of Transition-Metal Complexes of 2,2′-Dipyridylamine. 1. Bis Complexes of Rhodium(III) and Iridium(III)

Luminescence spectra, lifetimes, and polarization spectra have been measured for the + and + complexes (HDPA=2,2′-dipyridylamine).The complexes in acidic or neutral solution each show a broad, symmetric, and structurless red emission with microsecond lifetime assigned a dd* phosphorescence.In strong basic solution, the deprotonated complexes exhibit a blue asymmetric emission with a long tail overlapping the red-emission band.This blue emission shows no vibrational structure and has a lifetime on the order of microseconds.This emission is 0.35-mum-1 blue shifted with respect to the red emission and 0.56-mum-1 red shifted with respect to the phosphorescence of the ligand in strong basic solution.This emission can be assigned as charge-transfer dPi* emission analogous to that for the 2+ complex or as ligand-localized PiPi* emission.Such a dPi* emission from a Rh(III) complex would be unique.The emission polarization for the red dd* emission exhibits a nonzero slope across the band; moreover, the lifetime also varies with emission wavelength.This anomalous behavior is apparently intrinsic to dd* emission since similar data are obtained for dd* emission of the previously studied + complex.The origin of this unique behavior is not apparent but could have its origin in (1) solvent-induced barriers (distortions) in the emitting state and/or (2) intrinsic differences in vibrational relaxation rates with the emitting state.

Chemoselective deacylation of functionalized esters catalyzed by dioxomolybdenum dichloride

Among five different oxidometallic species and two Lewis acids investigated, MoO2Cl2 shows the best catalytic and chemoselective activity for the deacylation of esters in methanol at ambient or elevated temperature. Both high efficiency and chemoselectivity were achieved for substrates bearing different ether or ester groups. Acylated mono and disaccharides can also be selectively deacetylated in good yields, leading to useful carbohydrate templates for further synthetic manipulations.
