A series of thermo-sensitive hydrogels has been prepared from reactions of acylated poly(ethylene glycol) bis(carboxymethyl) ether (PEGBCOCl) (M(n)) = 600 dalton) with lactitol based polyether polyols (LPEPs). These LPEP hydrogels swelled extensively in water at neutral pH and their swelling behaviors depended strongly on the PEGBCOCl:LPEP molar ratios or extent of PEGBCOCl crosslinking. A maximum swelling of 81 fold was observed on hydrogels formed with LPEP (M(n)) = 4055 dalton) at a PEGBCOCl:LPEP molar ratio of 4.25. At temperatures above 25C, the hydrogels exhibited a phase transition and collapsed, expelling water. These super-absorbent hydrogels were stable under acidic conditions, but were sensitive to base hydrolysis. Enzyme proteins, i.e. lipase, were incorporated in the hydrogels (0.4-1.2 mg/g) by immersing the collapsed hydrogels in the protein solutions at 25C. Protein desorption at 40C occurred rapidly with over 90% of protein released during the first hour. The extent of protein desorption was similar among hydrogels with varying levels of absorbed proteins. The release of the lipase protein molecules is due to the structural collapse of the hydrogels and is not diffusion controlled. (C) 2000 Elsevier Science Ltd.

The reaction of AgNO3 and sulfobenzoate with neutral ligands led to the formation of three complexes, {[Ag2(4-sb)(Ph 3P)2(3-apy)]·(H2O)}n (1), {[Ag(PPh3)(2-apy)]·[Ag(PPh3)(3-sb)]·(H 2O)}n (2) and [Ag(PPh3)(Hdpa)(4-Hsb)] (3) (4-H2sb = 4-sulfobenzoic acid, PPh3 = triphenylphosphine, 3-apy = 3-aminopyridine, 2-apy = 2-aminopyridine, 3-H2sb = 3-sulfobenzoic acid, Hdpa = 2,2?-dipyridylamine) Complex 1 is a 2D sandwich-like polymer. Complex 2 is a cation-anion species and has a 1D polymer structure. Complex 3 is a monomer. Complexes 1-3 contain the Ag-PPh3 unit and such unit largely hinders the Ag-Ag, pi…pi, Ag…pi, and Ag…C interactions. The experimental results indicated that these three complexes have weaker conductivities than those corresponding silver complexes having abundant weak interactions, especially pi…pi and Ag-Ag interactions, illustrating that the cation-anion species having potential ability of charge transfer can largely promote the conductivity property.

Reactions of CuX (X = Br-, I- or CN-) with various types of 2,2?-dipyridylamine (dpa) derivatives have been performed via a hydrothermal-solvothermal method and the products have been structurally characterized by X-ray crystallography. Four ligands with different coordination motifs were employed in the reactions, including angular N,N,N?,N?-tetra(2-pyridyl)-2,6-pyridinediamine (tppda); linear N,N,N?,N?-tetra(2-pyridyl)-1,4-phenylenediamine (tppa) and N,N,N?,N?-tetra(2-pyridyl)biphenyl-4,4?-diamine (tpbpa); and star-shaped tris-[4-(2,2?-dipyridylamino)-phenyl]amine (tdpa), which yielded eight copper(i) complexes exhibiting different stoichiometries of Cu-dpa and variable coordination modes of dpa. The compound [Cu2(tppda) (mu-I)2]n (1) forms a one dimensional (1D) coordination polymer exclusively through double mu2-I bridges, which arranges to two dimensional (2D) metal-organic frameworks (MOFs) via the face-to-face pi…pi stacking interactions from pyridyl rings. The compound [Cu 6(tppa)(mu3-Br)6]n (2) forms a 2D network linked through multiple mu3-Br bridges. The compound [Cu2(tppa)(mu-CN)2]n (3) is also a 2D MOF containing 1D (CuCN)n chains. The compounds [Cu(tpbpa)Br]n (4) and [Cu4(tpbpa)2(mu-I)4]n (5) display two different 1D assemblies: a zig-zag chain for 4 and a linear structure for 5. The compound [Cu4(tpbpa)(mu-CN)4] n (6) shows a pseudo-4,82 topological net, while the compound [Cu8(tpbpa)(mu-CN)8]n· 2nH2O (7) exhibits a three-dimensional (3D) framework containing a …PM… double helical structure, although both of them contain (CuCN)n chains. The compound [Cu2(tdpa)(mu-I) 2]n (8) is a zig-zag chain based on the star-shaped molecule tpda, in which one of three dpa-arms is free of coordination to metal ions. All complexes exhibit luminescence in the solid state.

The monomeric compounds [Fe(dpa)2(X)2] ? solv [X = NCS-(solv = 0.5H2O) (1), N(CN)2- (2) and dpa = 2,2-dipyridilamine] have been synthesised and characterised. They crystallise in the P21/n and in the Cc monoclinic systems, respectively. Four of six nitrogen atoms coordinated to the Fe(II) ions belong to two dpa ligands which lie in cis conformation. The remaining positions are occupied by two nitrogen atoms of the pseudo-halide ligands. The magnetic susceptibility measurements at ambient pressure have revealed that compound 1 exhibits an incomplete spin crossover behaviour (T1/2 ? 88 K), whereas compound 2 remains in the high-spin configuration. Pressure studies performed on compound 1 have shown virtually complete spin crossover behaviour as pressure attains 6.5 kbar.

Curcumin has been shown to have a wide variety of biological activities for various human diseases including inflammation, diabetes and cancer. However, the poor oral bioavailability of curcumin poses a significant pharmacological barrier to its use therapeutically and/or as a functional food. Here we report the evaluation of the bioavailability and bio-efficacy of curcumin as an amorphous solid dispersion (ASD) in a matrix consisting of hydroxypropyl methyl cellulose (HPMC), lecithin and isomalt using hot melt extrusion for application in food products. Oral pharmacokinetic studies in rats showed that ASD curcumin was ?13-fold more bioavailable compared to unformulated curcumin. Evaluation of the anti-inflammatory activity of ASD curcumin in vivo demonstrated enhanced bio-efficacy compared to unformulated curcumin at 10-fold lower dose. Thus ASD curcumin provides a more potent and efficacious formulation of curcumin which may also help in masking the colour, taste and smell which currently limit its application as a functional food ingredient.

Three new triply-bridged dinuclear copper(II) compounds with carboxylato bridges, [Cu2(mu-O2CH)(mu-OH)(mu-Cl)(dpyam) 2](PF6) (1), [Cu2(mu-O2CH) 2(mu-OH)(dpyam)2](PF6) (2) and [Cu 2(mu-O2CCH2CH3) 2(mu-OH)(dpyam)2](ClO4) (3) (dpyam = di-2-pyridylamine) have been synthesized and characterized crystallographically and spectroscopically. Compound 1 consists of a dinuclear unit in which both copper(II) ions are bridged by three different ligands, i.e., formate, chloride and hydroxide anions, providing a distorted trigonal bipyramidal geometry with a CuN2O2Cl chromophore. Compounds 2 and 3 have two bridging formato ligands and two bridging propionato ligands, respectively, together with a hydroxo bridge. The carboxylato ligands in both compounds 2 and 3 exhibit different coordination modes. One is in a syn, syn eta1: eta1:mu2 bridging mode and the other is in a monoatomic bridging mode. The structure of compound 2 involves a dinuclear unit, with a distorted trigonal bipyramidal geometry around each Cu(II) ion with a CuN2O3 chromophore. Compound 3 contains a non-centrosymmetric unit; the coordination environment around Cu(1) is a distorted square-pyramidal geometry and an intermediate geometry of sp and tbp around the Cu(II) ion. The Cu?Cu separations are 3.061, 3.113 and 3.006 A? for compounds 1, 2 and 3, respectively. The EPR spectra of all three compounds show a broad isotropic signal with a g value around 2.10. The magnetic susceptibility measurements, measured from 5 to 280 K, revealed a moderate ferromagnetic interaction between the Cu(II) ions with a singlet-triplet energy gap (J) of 79.7, 47.8 and 24.1 cm-1, for compounds 1, 2 and 3, respectively. Also a very weak intermolecular antiferromagnetic interaction was observed between the dinuclear units.

Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. An article , which mentions 10343-06-3, molecular formula is C14H20O10. The compound – 2,3,4,6-Tetra-o-acetyl-D-glucopyranose played an important role in people’s production and life.

Phenethyl glycosides having phenolic or methoxy functions at benzene rings are substances widely occurring in nature. This kind of compounds has been shown to have anti-oxidant, anti-inflammatory, and anticancer activities. However, some of them are not naturally abundant, thus the synthesis of such molecules is desirable. In this paper, natural phenethyl glycosides 3 and 4 were first totally synthesized from easily available materials with overall yields of 50.5% and 40.1%, respectively. And a new synthetic route to obtain natural phenethyl glycoside 2 in 46.2% yield was also described.

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.Recommanded Product: 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, you can also check out more blogs about10343-06-3
