Programmable one-pot oligosaccharide synthesis

In an effort to develop a broadly applicable approach to the facile one- pot synthesis of oligosaccharides, the reactivity of a number of p- methylphenyl thioglycoside (STol) donors which are either fully protected or have one hydroxyl group exposed has been quantitatively determined by HPLC. We have characterized and quantified the influence on reactivity of the structural effects of different monosaccharine cores and different protecting groups on each glycoside donor. In addition, we have established a correlation between glycosyl donor reactivity and the chemical shift of the anomeric proton by 1H NMR. Using the reactivity data, we have created a database of thioglycosides as glycosyl donors and demonstrated its utility in the easy and rapid one-pot assembly of various linear and branched oligosaccharide structures. In addition, we have developed the first computer program, OptiMer, for use as a database search tool and guide for the selection of building blocks for the one-pot assembly of a desired oligosaccharide or a library of individual oligosaccharides.

Synthesis of Heteroleptic Bis(diimine)carbonylchlororuthenium(II) Complexes from Photodecarbonylated Precursors

The reactions of bidentate diimine ligands (L2) with binuclear [Ru(L1)(CO)Cl2]2 complexes [L1 ? L2 = 2,2?-bipyridine (bpy), 4,4?-dimethyl-2,2? -bipyridine (4,4?-Me2bpy), 5,5?-dimethyl-2,2? -bipyridine (5,5?-Me2bpy), 1,10-phenanthroline (phen), 4,7-dimethyl-1,10-phenanthroline (4,7-Me2phen), 5,6-dimethyl-1,10-phenanthroline (5,6-Me2phen), di(2-pyridyl)ketone (dpk), di(2-pyridyl)amine (dpa)] result in cleavage of the dichloride bridge and the formation of cationic [Ru(L1)(L2)(CO)Cl] + complexes. In addition to spectroscopic characterization, the structures of the [Ru(bpy)(phen)(CO)Cl]+, [Ru(4,4?-Me 2bpy)(5,6-Me2phen)(CO)Cl]+ (as two polymorphs), [Ru(4,4?-Me2bpy)(4,7-Me2phen)(CO)Cl]+, [Ru(bpy)(dpa)(CO)Cl]+, [Ru(5,5?-Me 2bpy)(dpa)(CO)Cl]+, [Ru(bpy)(dpk)(CO)Cl]+, and [Ru(4,4?-Me2bpy)(dpk)(CO)Cl]+ cations were confirmed by single crystal X-ray diffraction studies. In each case, the structurally characterized complex had the carbonyl ligand trans to a nitrogen from the incoming diimine ligand, these complexes corresponding to the main isomers isolated from the reaction mixtures. The synthesis of [Ru(4,4?-Me2bpy)(5,6-Me2bpy)(CO)(NO 3)]+ from [Ru(4,4?-Me2bpy)(5,6-Me 2bpy)(CO)Cl]+ and AgNO3 demonstrates that exchange of the chloro ligand can be achieved.

Potent anti-proliferative actions of a non-diuretic glucosamine derivative of ethacrynic acid

Ethacrynic acid (EA), a known inhibitor of the neoplastic marker glutathione S-transferase P1 and other GSTs, exerts a weak antiproliferative activity against human cancer cells. The clinical use of EA (Edecrin) as an anticancer drug is limited by its potent loop diuretic activity. In this study, we developed a non-diuretic 2-amino-2-deoxy-d-glucose conjugated EA (EAG) to target tumors cells via the highly expressed glucose transporter 1 (GLUT1). Cell survival assays revealed that EAG had little effect on normal cells, but was cytotoxic 3 to 4.5-fold greater than EA. Mechanistically, the EAG induced selective cell death in cancer cells by inhibiting GSTP1 and generating abundant reactive oxygen species. Furthermore, EAG induced p21cip1 expression and a G2/M cell cycle block irrespective of the p53 gene status in tumor cells. These data encourage the development of new EA analogs.

A generalized procedure for the one-pot preparation of glycosyl azides and thioglycosides directly from unprotected reducing sugars under phase-transfer reaction conditions

Per-O-acetylated glycosyl azides and thioglycosides were prepared in excellent yield directly from unprotected reducing sugars through in situ generation of per-O-acetylated glycosyl bromides by a generalized one-pot procedure under phase-transfer conditions. Stereoselective products were formed with complete inversion at the anomeric centers of the glycosyl bromides to provide a general high-yielding procedure for the preparation of 1,2-trans-glycosyl azides and thioglycosides.

Transglycosylations employing recombinant alpha- And beta-galactosidases and novel donor substrates

Recombinant alpha- and beta-galactosidases could be prepared in larger amounts for chemoenzymatic syntheses of glycosylated oligosaccharides relevant in nutrition approaches. alpha-Galactosidase RafA from Escherichia coli, another thermophilic alpha-galactosidase AgaB from Geobacillus stearothermophilus KVE39, and also a thermophilic beta-galactosidase BglT from Thermus thermophilus TH 125 could be employed in alpha- and in beta-glycosylations, respectively. With model structures as well as sucrose, isomaltitol, and isomaltulose the stereo- and regiospecificities were studied. Further, a number of modified donor structures with structural variation and different leaving groups were synthesized, employed, and compared to classical donors for these transglycosylations.
