Use of N,O-dimethylhydroxylamine as an anomeric protecting group in carbohydrate synthesis

The N,O-dimethyloxyamine-N-glycosides are introducedas anomerically protected building blocks for carbohydrate synthesis. These N-glycosides are stable to a variety of protecting group manipulations including acylation, alkylation, silylation, and acetal formation. The alkoxyamine-N-glycosides can be cleaved selectively with N-chlorosuccinimide to give the desired hemiacetals in excellent yield. Furthermore, these Nglycosides are stable to the activation conditions required for glycosylation using thioglycoside and trichloroacetimidate glycosyl donors suggesting N,O-dialkoxyamine-N-glycosides will be useful for complex oligosaccharide synthesis.

Design and synthesis of hyaluronan-mimetic gemini disaccharides

An efficient strategy has been designed for the preparation of synthetic mimics of hyaluronan (HA, 1) and its dimerized (Gemini) disaccharides (2a,b) via n-pentenyl glycoside formation. Construction of the target molecules was achieved through a combination of protection/deprotection protocols, imidate glycosylation methodology followed by ozonolysis, and reductive amination. These tailored synthetic mimics could act as versatile building blocks with therapeutic applications in tissue engineering, treatment of cancer and as drug delivery agents.

Selective copper(II)-mediated oxidative coupling of a nucleophilic reagent to the para-methyl group of 2,4,6-trimethylphenol

A copper(II) neocuproine system has been developed for the efficient and very selective 1,6-addition of a nucleophile to the para-methyl group of 2,4,6-trimethylphenol. Crystallographic and spectroscopic data point towards the involvement of a mu-methoxo-mu-phenoxo-bridged copper species which appears to generate a highly reactive quinone methide intermediate that can be attacked by a nucleophilic reagent.

New silibinin glyco-conjugates: Synthesis and evaluation of antioxidant properties

New silibinin glyco-conjugates have been synthesized by efficient method and in short time. Exploiting our solution phase strategy, several structurally diverse silibinin glyco-conjugates (gluco, manno, galacto, and lacto-) were successfully realized in very good yields and in short time. In preliminary study to evaluate their antioxidant and neuroprotective activities new derivatives were subjected to DPPH free radical scavenging assay and the Xanthine oxidase (XO) inhibition models assay. Irrespective of the sugar moiety examined, new glyco-conjugates are more than 50 times water-soluble of silibinin. In the other hand they exhibit a radical scavenging activities slightly higher than to silibinin and XO inhibition at least as silibinin.

Emission Studies of Transition-Metal Complexes of 2,2′-Dipyridylamine. 2. Tris Complexes of Ruthenium(II)

The tris complex of Ru(II) with 2,2′-dipyridylamine (HDPA) has been prepared and characterized.Luminescence spectra, lifetimes, and photoselection spectra have been measured for various protonated and deprotonated forms of the complex in aqueous and nonaqueous solution.The fully protonated 2+ shows a weak, broad, symmetric, and structureless emission of microsecond lifetimes at low energy assigned as a dd+ phosphorescence.The complexes of the deprotonated dipyridylamine ligand (DPA-) exhibit broad, asymmetric, and structureless emission at higher energy with microsecond lifetimes.The emission for these deprotonated complexes is assigned as charge-transfer IId* emission, and, as a consequence, the emission for the – and – complexes (previously reported as dII* emitters) is reconsidered.The + and – complex ions show spatially isolated (single-ring) emission in nonaqueous solvents; however, evidence exists that the emission for the neutral 0 complex is multiring in nature.Spectral data are also presented for an aquated form of the fully deprotonated complex, -, which has also been isolated as a solid product.

Substituted oxazolidinones as novel NPC1L1 ligands for the inhibition of cholesterol absorption

Cholesterol absorption inhibition (CAI) represents an important treatment option for hypercholesterolemia. Herein, we report the design and evaluation of a series of substituted oxazolidinones as ligands for the Niemann Pick C1 Like 1 (NPC1L1) protein, a key mediator of cholesterol transport. Novel analogs were initially evaluated in a brush border membrane NPC1L1 binding assay; subsequently, promising compounds were evaluated in vivo for acute inhibition of cholesterol absorption. These studies identified analogs with low micromolar NPC1L1 binding affinity and acute in vivo efficacy of >50% absorption inhibition at 3 mg/kg.

Chiral and achiral 1D copper(ii) coordination polymers based on glycolato and chelating aromatic diamine ligands

Achiral glycolic acid and chelating aromatic diamine ligands were employed at room temperature to prepare five 1D copper(ii) coordination polymers which were structurally characterized. The polymers ?1{[Cu(HG)(dipyam)](HG)} (1) (dipyam = 2,2?-dipyridylamine) and ?1[Cu(HG)(ClO4)(NN)] (NN = 2,2?-bipyridine (2), NN = 1,10-phenanthroline (3)) adopt homochiral helical structures in the crystal state and undergo spontaneous chiral resolution in the solid state. On the other hand, the polymers containing bidepronated glycolato ligand G, ?1{[Cu(G)(dipyam)]¡¤H2O} (1a), obtained from a solution of 1 in MeOH/iPrOH and ?1{[Cu2(mu-G)(ClO4)(H2O)(dipyam)2](ClO4)(H2O)2} (4b) are achirals. Crystals of 4b have been obtained together with crystals of the molecular complex [Cu(HG)(H2O)(dipyam)](ClO4) (4a). Analysis by Hirshfeld surface generation and two-dimensional fingerprinting was carried out to study the nature of the interactions and their contributions towards the crystal packing.
