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.

The reaction of NiCl2 with the non-steroidal anti-inflammatory drug diflunisal (Hdifl) resulted in the formation of complex [Ni(difl-O)2(MeOH)4], 1. The co-existence of a N,N’-donor heterocyclic ligand 2,2?-dipyridylketone oxime (Hpko), 1,10-phenanthroline (phen), 2,2?-bipyridine (bipy) and 2,2?-bipyridylamine (bipyam) led to the formation of complexes [Ni(difl-O)2(Hpko-N,N’)2], 2, [Ni(difl)2(phen)(MeOH)2], 3, [Ni(difl)2(bipy)(MeOH)2], 4 and [Ni(difl-O,O’)2(bipyam)], 5, respectively. The complexes were characterized by physicochemical and spectroscopic techniques and the crystal structures of complexes 1 and 2 were determined by X-ray crystallography. The ability of the complexes to scavenge in vitro 1,1-diphenyl-picrylhydrazyl, 2,2?-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) and hydroxyl radicals was investigated; the complexes were more active scavengers than free Hdifl. The interaction of the complexes with serum albumins was investigated by fluorescence emission spectroscopy and the binding constants of the compounds to the albumins were calculated. UV spectroscopy, cyclic voltammetry and viscosity measurements as well as fluorescence emission spectroscopy for the competitive studies of the complexes with ethidium bromide were employed so as to monitor the interaction of the compounds with calf-thymus DNA and revealed intercalation as the most possible mode of binding.

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.

Nucleotides are essential components of DNA and RNA, and their functions depend mainly on the participation of metal ions. Thus, research into nucleotide-metal coordination complexes, including the affinities of different coordination donors for metal ions, molecular and crystal structures, supramolecular assembly, and functional nanoparticles, will contribute to the interdisciplinary field of chemistry, biology, and materials. Numerous achievements have been reported in this area but few comprehensive reviews have considered nucleotide-metal complexes from the viewpoints of crystallography and supramolecular chemistry, or aspects of their chirality and chirality delivery. In this review, we describe the coordination ability of nucleotide ligands, the structures and properties of nucleotide-metal coordination complexes, and supramolecular assemblies. We review mononuclear complexes, multinuclear complexes, 1D and 2D coordination polymers, and 3D supramolecular assemblies in terms of their structures, mainly based on their X-ray single crystal diffraction data. In particular, we highlight the chirality of nucleotide-metal complex, including their molecular chirality, supramolecular helical chirality, and extended axial chirality. Furthermore, we summarize the functional properties of nucleotide-metal nanomaterials, such as their luminescence, magnetism, and adaptive inclusion properties. We discuss the future challenges and opportunities of research into nucleotide-metal complex.

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.COA of Formula: C12H22O11, you can also check out more blogs about499-40-1

Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. Introducing a new discovery about 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, 10343-06-3.

Carbohydrates are extremely important biomolecules and their immobilization onto solid surfaces is of interest for the development of new biomimetic materials and of new methods for understanding processes in glycobiology. We have developed an efficient surface modification methodology for the functionalization of a range of materials with biologically active carbohydrates based on aryldiazonium chemistry. We describe the synthesis and characterization of carbohydrate reagents, which were subsequently employed for the one-step, solution-based modification of carbon, metals, and alloys with monosaccharides. We used a combination of spectroscopic and nanogravimetric methods to characterize the structure of the carbohydrate layers; we report an average surface coverage of 7.8 × 10-10 mol cm-2 under our experimental conditions. Concanavalin A, a mannose-binding lectin, and Peanut Agglutinin, a galactose-binding lectin, were found to bind from solution to their respective monosaccharide binding partners immobilized at the surface. This result suggests that the spontaneous chemisorption of aryldiazonium monosaccharide precursors leads to the formation of monosaccharide layers that retain the biological recognition specificity of the parent carbohydrate molecule. Finally, we carried out measurements using fluorescently labeled Bovine Serum Albumin (BSA) and found that these carbohydrate coatings reduce unspecific adsorption of this protein at carbon surfaces. These results suggest that aryldiazonium-derived carbohydrate coatings may offer a promising strategy for preventing undesirable protein accumulation onto surfaces.

The development of the tetra-O-acetyl-D-glucopyranosyloxycarbonyl (AGlOC) and tetra-O-acetyl-beta-D-galactopyranosyloxycarbonyl (AGalOC) protecting groups, which are fully enzyme-labile, carbohydrate-derived urethanes, is described. The protected amino acids were easily synthesized and subsequently converted into a series of model dipeptides through classical peptide couplings. Cleavage of an alpha/beta-anomeric mixture of a model AGlOC dipeptide was achieved with a ‘one-pot’ procedure in good yield. To gain a better understanding of the enzymatic deprotection reaction, the AGalOC group was removed formation (lipase catalyzed deacetylation, followed by beta-galactosidase catalyzed glycosidic bond fragmentation). Under these very mild reaction conditions (aq. buffer pH7.0, 37C), the desired N-terminal, unprotected dipeptide conjugates were obtained. The methodology was further utilized for the synthesis of an advanced tetrapeptide model system.

Based on the ligand 2,2?-dipyridylamine (Hdpa) and di?2-pyrazyl?amine?Hdpza?, neutral molecular complexes [Co(Hdpa)2(NCS)2] (1) and [Co(Hdpza)2(NCS)2] (2) were synthesized. The DFT calculation of complex 1 was carried out to analyze the electron density distribution. Magnetic results indicate that a gradual decrease in chiMT over the entire temperature range indicates strong zero-field splitting for the high-spin Co(II) ion in 1. The complex was used for the cycloaddition reaction of CO2 and propylene oxide, and compared with the reported complex 2 [Co(Hdpza)(NCS)2], the catalytic activity was 1 > 2. The Complex 1 exhibited excellent catalytic performance for converting CO2 into cyclic carbonates under mild conditions. For propylene oxide (PO) and CO2 synthesis of propylene carbonate (PC), the catalytic system showed a remarkable TOF as high as 5040 h?1.
