An efficient and versatile chemical synthesis of bioactive glyco-glycerolipids

Synthesis of beta-glyco-1,2-diacylglycerols is achieved by a versatile and simple procedure based on trichloro-acetimidate methodology and use of peracetate sugar substrates. The chemical strategy was tested through stereoselective preparation of beta-galacto- and beta-gluco-lipid derivatives capable to trigger immune system response. The synthetic approach is designed to obtain enantiomerically pure regio- and stereo-isomers including derivatives containing poly-unsaturated fatty acids.

Synthesis and biological activity of novel N-glucosides containing substituted piperazine moiety

A series of novel acetylated piperazine-containing N-glucosides and bis(N-glucoside) 8a-i were synthesized by the nucleophilic addition of acetylated glucopyranosyl isothiocyanate with various substituted piperazines in THF with high yields. Their novel deacetylated products 9a-i were also synthesized after Me-ONa/MeOH treatment. The preliminary bioassays for 18 novel title compounds showed that several compounds have significant fungicidal activity against Fusarium omysporum, Cercospora arachidicola and Phytophthora capsici at 50 mug/mL.

Non-steroidal antiinflammatory drug-copper(II) complexes: Structure and biological perspectives

Copper(ii) complexes with the non-steroidal antiinflammatory drug mefenamic acid in the presence of aqua or nitrogen donor heterocyclic ligands (2,2?-bipyridine, 1,10-phenanthroline, 2,2?-bipyridylamine or pyridine) have been synthesized and characterized. The crystal structures of [(2,2?-bipyridine)bis(mefenamato)copper(ii)], 2, [(2,2?- bipyridylamine)bis(mefenamato)copper(ii)], 4, and [bis(pyridine)bis(methanol) bis(mefenamato)copper(ii)], 5, have been determined by X-ray crystallography. UV study of the interaction of the complexes with calf-thymus DNA (CT DNA) has shown that the complexes can bind to CT DNA and [bis(aqua)tetrakis(mefenamato) dicopper(ii)] exhibits the highest binding constant to CT DNA. The cyclic voltammograms of the complexes in the presence of CT DNA solution have shown that the complexes can bind to CT DNA by the intercalative binding mode verified also by DNA solution viscosity measurements. Competitive studies with ethidium bromide (EB) indicate that the complexes can displace the DNA-bound EB suggesting strong competition with EB. Mefenamic acid and its complexes exhibit good binding propensity to human or bovine serum albumin protein having relatively high binding constant values. All the compounds have been tested for their antioxidant and free radical scavenging activity as well as for their in vitro inhibitory activity against soybean lipoxygenase showing significant activity.

Bis(acetato-kappa 2O,O?)(di-2-pyridyl-kappaN-amine)copper(II) dihydrate

The copper(II) ion in the title complex, [Cu(C2H3O2)2-(C10H 9N3)].2H2O, is coordinated unsymmetrically to each of the two bidentate acetate ligands and to the N atoms of the di-2-pyridylamine (dpyam) ligand. The copper(II) ion is surrounded by a distorted square-based arrangement of the two dpyam pyridyl N atoms at distances of 1.974 (2) and 1.995 (2) A, and by two acetate O atoms at distances of 1.965 (1) and 1.967 (1) A. The second O atom from each acetate group is involved in weak coordination in the tetragonal positions, at longer Cu-O distances of 2.482 (2) and 2.690 (2) A, completing the six-coordination. The overall geometry at the copper(II) ion is best described as distorted octahedral with elongated axial bonds.

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

Two new poloxometalate-based organic/inorganic hybrid compounds, 4(2,2?-DPA)¡¤pseudo-alpha-H4SiMo12O 40¡¤4DMF¡¤2H2O (1) and 4(2,2?-DPA)¡¤pseudo-alpha-H4SiMo12O 40¡¤2H2O (2), have been synthesized and characterized. The crystals of 1 belong to the space group P-1 with a = 13.068 (3), b = 13.706 (2), c = 13.724 (2) A?, alpha = 89.325 (18), beta = 62.516 (11), gamma = 82.260 (15), V = 2157.3 (7) A?3, Dc = 2.183 g/cm3, Z = 1, R = 0.0979 and the crystals of 2 belong to the space group P-1 with a = 11.4688 (10), b = 12.6435 (11), c = 12.8070 (12) A?, alpha = 110.745 (2), beta = 105.329 (2), gamma = 90.46 4 (2), V = 1664.2 (3) A?3, Dc = 2.539 g/cm3, Z = 1, R = 0.0543. Spectroscopic data support the presence of a sizeable electronic interaction between the electron-rich organics and the inorganic SiMo12O404- anions in 1 as well as in 2, both in the solid state and in solution, provided the hybrid compounds are present in high concentrations. The crystal structure determination reveals the absence of any substantial, direct interaction between the organics and the polyoxoanions both within compounds 1 and 2. Therefore the inherent relationship between molecular and crystal structure and the charge-transfer interaction cannot be given yet, despite that it is found that the charge-transfer strength is somewhat related to the distance between the organics and the polyoxoanions.

A tetranuclear manganese carboxylate cluster with bis(2-pyridyl)amine ligation: [Mn4O2(O2CEt)7 (bpya)2](ClO4)

The title complex has been prepared and characterized by X-ray crystallography, magnetochemistry, cyclic voltammetry and 1H NMR spectroscopy. The complex contains a [Mn4(mu3-O)2]8+ core with bridging EtCO2- and chelating bpya groups. The magnetochemical studies indicate an S = 0 ground state as a result of antiferromagnetic exchange interactions between the MnIII ions. The 1H NMR spectra support retention of the solid-state structure on dissolution in MeCN.
