Synthesis and Hydrolytic Stability of N- and O-Methyloxyamine Linkers for the Synthesis of GlycoconjugatesSynthesis and Hydrolytic Stability of N- and O-Methyloxyamine Linkers for the Synthesis of Glycoconjugates

A comparison of the merits of N- and O-methyloxyamines as linkers for carbohydrates is presented for the first time. In particular, optimized synthetic routes for each linker type are given, and the ease of glycan conjugation is described. The hydrolytic stabilities of the respective oxyamine glycoconjugates under a variety of different conditions are reported. This provides insight into the factors that influence hydrolysis rates, and sheds light on the acid-catalysed hydrolysis mechanism.

Inhibitory action of palatinose and its hydrogenated derivatives on the hydrolysis of alpha-glucosylsaccharides in the small intestine

This study was conducted to investigate the inhibitory effects of palatinose and Palatinit, which are disaccharides (or disaccharide alcohol) connected through an alpha-1,6-glucosyl linkage, on the hydrolysis of other carbohydrates, using an enzyme extract from the rat small intestine and a purified sucrase-isomaltase complex. Palatinose and its hydrogenated product, Palatinit, an equimolar mixture of alpha-O-D-glucopyranosyl-1,6-D-sorbitol (GPS) and alpha-O-D-glucopyranosyl-1,6-D-mannitol (GPM), inhibited the hydrolysis of sucrose and maltose. Palatinose and Palatinit also inhibited the hydrolysis of dextrin and soluble starch. Kinetic analysis of the enzymatic inhibition by GPS and GPM on sucrose hydrolysis revealed that both GPS and GPM competitively inhibit sucrase catalytic activity. These results suggest that disaccharides with an alpha-1,6-glucosyl linkage competitively inhibit intestinal alpha-glucosidases and may reduce the rate of hydrolysis of sucrose and other alpha-glucosylsaccharides.

N-Linked Glycosyl Auxiliary-Mediated Native Chemical Ligation on Aspartic Acid: Application towards N-Glycopeptide Synthesis

A practical approach towards N-glycopeptide synthesis using an auxiliary-mediated dual native chemical ligation (NCL) has been developed. The first NCL connects an N-linked glycosyl auxiliary to the thioester side chain of an N-terminal aspartate oligopeptide. This intermediate undergoes a second NCL with a C-terminal thioester oligopeptide. Mild cleavage provides the desired N-glycopeptide.

Synthesis and mixed valence aspects of [{(L)ClRu} 2(mu-tppz)]n+ incorporating 2, 2?-dipyridylamine (L) as ancillary and 2,3,5,6-tetrakis(2-pyridyl)pyrazine (tppz) as bridging ligand

The tppz-bridged diruthenium complex [{(L)ClRuII} 2(mu-tppz)](ClO4)2, [1](ClO4) 2 {tppz = 2,3,5,6-tetrakis(2-pyridyl)pyrazine, L = 2,2?-dipyridylamine} and its mononuclear counterpart [(L)ClRu II(tppz)]ClO4, [2](ClO4) have been synthesized. The 380 mV separation between successive RuII/RuIII couples in [1]2+ leads to a comproportionation constant (K c) of 2.7 ¡Á 106. Consequently, the Ru IIRuIII species [1]3+ exhibits a rather narrow intervalence charge transfer band at 1700 nm, suggesting a class III mixed-valence state, the electronic coupling constant (Vab) is calculated at 2940 cm-1. Complex [1]3+ displays a rhombic EPR spectrum at 4 K (g1 = 3.390, g2 = 2.278, g 3 = 1.697), characteristic of ruthenium(III) in a distorted octahedral environment. Both complexes show two successive tppz-based reduction processes [(tppz)0/-1 and (tppz)-1/-2]. The one-electron reduced species [1]+ is a tppz radical anion species with an intense low-energy band at 1105 nm and an axial EPR signal at 4 K (g1 = 2.008, g2 = g3 = 1.994). [1]2+ and [2] + exhibit moderately strong emissions at 740 nm and 668 nm, respectively, in EtOH-MeOH glass at 77 K.

Synthesis, Spectroscopic and Molecular Studies of Half-Sandwich eta6-Arene Ruthenium, Cp Rhodium and Cp Iridium Metal Complexes with Bidentate Ligands

The bidentate ligand benzoyl(2-pyridyl)thiourea (L1) was prepared by reaction of benzoyl isothiocyanate with primary amine (2-aminopyridine) but the reaction with secondary amine bis(2-pyridyl)amine, yielded the unexpected product bis(2-pyridyl)benzoylamine (L2). Mononuclear complexes of the general formula [(eta6-arene)Ru(L)Cl]+ {where, L = L1, arene = benzene (1); p-cymene (2); L = L2, arene = benzene (5); p-cymene (6)} and [CpM(L)Cl]+ {where, L = L1, M = Rh (3), Ir (4); L = L2, M = Rh (7), Ir (8)}, respectively, were formed by reaction of the ligands L1 and L2 with precursor complexes [(eta6-arene)Ru(mu-Cl)Cl]2 and [CpM(mu-Cl)Cl]2 (M = Rh, Ir). The cationic complexes were characterized by FT-IR, UV/Vis, and 1H-NMR spectroscopy as well as mass spectrometry. X-ray crystallographic studies of these complexes reveal piano-stool-like arrangements around the metal atoms with six-membered metallacycles in which L1 and L2 act as a N, S- and N, N’ chelating ligands, respectively.

Novel copper complexes based on the thiocyanate bridge – Synthesis, X-ray studies and magnetic properties

Three novel compounds {[Cu(bpzm)(SCN)][Cu(bpzm)(MeOH)][Cu(SCN) 4]}n (1a), {[Cu2(bpzm)2(mu-SCN) (SCN)3]}n (1b) and [Cu2(mu-SCN) 2(SCN)2(dpa)2] (2) have been obtained in one-step self-assembly reaction of copper dichloride, a suitable N-N ligand (bis(pyrazol-1-yl)methane and 2,2?-dipyridylamine) and ammonium thiocyanate. For the reaction involving bis(pyrazol-1-yl)methane, an unprecedented in situ reduction of some Cu(II) ions to Cu(I) has been observed. The compound {[Cu(bpzm)(SCN)][Cu(bpzm)(MeOH)][Cu(SCN)4]}n (1a) belongs to a relatively scarce group of mixed-valence Cu II/CuI coordination polymers with interesting polymeric architecture. It creates infinite two-dimensional structure consisting of layers extending along crystallographic plane (0 0 1), in which the cations [Cu II(bpzm)(SCN)]+ and [CuII(bpzm)(MeOH)] 2+ are connected by ions [CuI(SCN)4] 3- through single end-to-end thiocyanato bridges. Structure 1b consists two crystallographically independent chains. The chain A has a zig-zag form and extends along the crystallographic direction [0 0 1], whereas the second chain is linear and runs along the crystallographic direction [0 1 0]. The structure 2 consists of dinuclear [Cu2(dpa)2(mu-SCN) 2(SCN)2] units. Variable-temperature magnetic susceptibility measurements show very weak antiferromagnetic interactions between the paramagnetic centres Cu(II) centers inside the crystal lattices of three novel compounds.
