Axial extension of metal string complexes: Crystal structure of {Ni3(dpa)4[Ag(CN)2]2}

A novel complex, Ni3(dpa)4[Ag(CN)2]2 (1), was synthesized and structurally characterized. The first example of metal string complex with axial metallic ligand shows length of 20.5 A. Axial [Ag(CN)2]- ligands still remain two vacant sites, which potential possibly form longer string complex.

Structure and biological activities of metal complexes of flumequine

The reaction of CoCl2¡¤6H2O with the quinolone antimicrobial agent flumequine (Hflmq) in the absence or presence of the alpha-diimines 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen) or 2,2?-bipyridylamine (bipyam) resulted in the formation of four mononuclear complexes which were characterized with physicochemical and spectroscopic techniques. The crystal structures of [Co(flmq)2(bipy)]¡¤2H2O, [Co(flmq)2(phen)]¡¤1.6MeOH¡¤0.4H2O and [Co(flmq)2(bipyam)]¡¤H2O were determined by X-ray crystallography. The interaction of the complexes with calf-thymus DNA (CT DNA) was investigated by UV spectroscopy, viscosity measurements, cyclic voltammetry and competitive studies with ethidium bromide in order to evaluate the possible DNA-binding mode and to calculate the corresponding DNA-binding constants. The binding of the complexes to human or bovine serum albumin was studied by fluorescence emission spectroscopy and the corresponding binding constants were determined. The antimicrobial activity of the Co(II)-flumequine and the recently reported Cu(II)-flumequine complexes was tested against four different microorganisms (Escherichia coli, Xanthomonas campestris, Staphylococcus aureus and Bacillus subtilis) and was found to be similar to that of free Hflmq. The antiproliferative activity of previously reported complexes [Cu(flmq)(phen)Cl], [Zn(flmq)(phen)Cl] and [Ni(flmq)2(phen)] against human ovarian (A2780) and lung (A549) cancer cell lines is also reported in comparison to the cobalt analogue, [Co(flmq)(phen)Cl], 3, highlighting important differences among the various complexes which may be due to different uptake and modes of action.

3-(Dimethylamino)-1-propylamine: A cheap and versatile reagent for removal of byproducts in carbohydrate chemistry

Inexpensive 3-(dimethylamino)-1-propylamine (DMAPA) was found to be effective in anomeric deacylation reactions giving 1-O deprotected sugars in high yield as precursors for the formation of imidate glycosyl donors. DMAPA was also found to be useful for removing excess reagents such as benzoyl chloride, tosyl chloride, and 2,2,2-trifluoro-N-phenylacetimidoyl chloride. The deacylation reaction could be conducted in moist THF and did not require chromatographic purification since an acidic wash was sufficient to remove excess reagent and the formed byproduct.

Molecular engineering to improve the charge carrier balance in single-layer silole-based OLEDs

We report a molecular engineering study on optical, structural and electrical properties of seven silole derivates aimed at enhancing the charge carrier balance in single-layer devices. By functionalizing two hole-transporting groups, dipyridylamine and anthracene, on the silole ring, we have investigated the influence of both substituents on the hole current. We have concluded that in contrast to dipyridylamine groups, anthracene groups decrease the charge carrier balance since the latter groups not only increase the hole current but also electron contribution. Mixing these hole-transporting groups and doubling their number lead to a novel silole becoming a very efficient emissive layer exhibiting threshold voltage below 3 V and luminous efficiency Le = 0.8 cd A-1 at 7 V.

Transglycosylation in a two-phase aqueous-organic system with catalysis by a lipid-coated beta-D-galactosidase

A lipid-coated beta-D-galactosidase was prepared in which the enzyme surface is covered with a lipid monolayer and two long alkyl lipophilic tails serve to solubilize the enzyme in organic solvents. In a two-phase aqueous-organic system, a lipid-coated enzyme exists in the organic (2-propyl ether) phase and acts as an efficient transgalactosylation catalyst for various hydrophobic alcohols with lactose in the aqueous buffer solution. When a native beta-D-galactosidase was employed in the two-phase system, neither the transgalactosylation nor the hydrolysis reaction proceeded due to denaturation of the enzyme at the interface. Effects of coating lipid molecules, origins of enzymes, reaction in organic solvents, and chemical structures of acceptor alcohols on the transgalactosylation catalyzed by the lipid-coated enzyme were studied. This system could also be applied in a large-scale synthesis on the 0.1-1 g scale.

Synthesis of bis(C-glycosyl)flavonoid precursors

Treatment of 3,5-dimethoxyphenol with one equivalent of O-glucosyl trichioroacetimidate I in the presence of TMSOTf as catalyst afforded, in a Fries-type reaction, C-glucosyl compound 4. Reaction of 4 with one equivalent of I or with one equivalent of O-galactosyl trichloroacetimidate 8 gave, under similar reaction conditions, bis(C-glycosyl) compounds 5 and 9, respectively. Hydrogenolytic O-debenzylation of 5 afforded 3,5-dimethoxy- 2,6-bis(beta-D-glucopyranosyl)phenol (6) in high yield. Due to hindered rotation around the C-glycosyl C-C bond, structural assignment was carried out by recording 1H NMR spectra at elevated temperatures.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 74808-09-6, you can also check out more blogs about74808-09-6
