Crystal structures, spectro-structural correlation and structural pathways of eight [Cu(dpyam)2(NCO)][Y] complexes (dpyam = di-2-pyridylamine), Y = Br-, CF3 SO3-, BF4- · dpyam, Cl- · 4H2O, NO3-, PF6-, ClO[…].

The crystal structures of eight new [Cu(dpyam)2(NCO)][Y] complexes which Y = Br- (1), CF3 SO3- (2), BF4- · dpyam (3), Cl- · 4H2O (4), NO3- (5), PF6- (6), ClO4- (7) and BPh4- (8), respectively have been determined by X-ray crystallography. Five of the complexes, 1-5 (tau = 0.09-0.30) have a CuN4N? chromophore with a trigonal bipyramidal distorted square based pyramidal (TBDSBP) stereochemistry, 6 and 7 (tau = 0.53-0.54) involve an intermediate five-coordinate stereochemistry, while 8 (tau = 0.76) involves a square base pyramidal distorted trigonal bipyramidal (SBPDTB) stereochemistry. The structures of 1-8 are compared by scatter-plot analysis with [Cu(dpyam)(NCO)][SO4]0.5 · dpyam · 0.5H2O (9), the only complex of known crystal structure within this series reported to date. Scatter plots of the cations distortion isomers of the [Cu(dpyam)2(NCO)][Y] series of complexes suggests that all nine complexes lie on a common structural pathway, involving a mixture of symmetric, nusym, C2 mode and asymmetric, nuasym, non-C2 modes of vibration of the CuN4N? chromophore. The resulting linear and parallel structural pathways are consistent with the direct observation of the effect of vibronic coupling on the stereochemistries of the complexes, which can range from SBPDTB to TBDSBP which correlate with electronic spectral data. The EPR spectra (K-band and V-band) of complexes 1-7 are in rhombic type, while complex 8 is axial with g? = 2.185 and g? = 2.005, consistent with a dz2 ground state for the approximately trigonal bipyramidal stereochemistry of the CuN4N? chromophore. These are in agreement with electronic reflectance spectra of the complexes and correspond to their stereochemistries.

Swelling and protein absorption/desorption of thermo-sensitive lactitol- based polyether polyol hydrogels

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.

Synthesis of a poly-hydroxypyrolidine-based inhibitor of Mycobacterium tuberculosis GlgE

(Chemical Equation Presented). Long treatment times, poor drug compliance, and natural selection during treatment of Mycobacterium tuberculosis (Mtb) have given rise to extensively drug-resistant tuberculosis (XDR-TB). As a result, there is a need to identify new antituberculosis drug targets. Mtb GlgE is a maltosyl transferase involved in alpha-glucan biosynthesis. Mutation of GlgE in Mtb increases the concentration of maltose-1-phosphate (M1P), one substrate for GlgE, causing rapid cell death. We have designed 2,5-dideoxy-3-O-alpha-D-glucopyranosyl-2,5-imino-D-mannitol (9) to act as an inhibitor of GlgE. Compound 9 was synthesized using a convergent synthesis by coupling thioglycosyl donor 14 and 5-azido-3-O-benzyl-5-deoxy-1,2-O-isopropylidene-alpha-D-fructopyranose (23) to form disaccharide 24. A reduction and intramolecular reductive amination transformed the intermediate disaccharide 24 to the desired pyrolidine 9. Compound 9 inhibited both Mtb GlgE and a variant of Streptomyces coelicolor (Sco) GlgEI with Ki = 237 ± 27 muM and Ki = 102 ± 7.52 muM, respectively. The results confirm that a Sco GlgE-V279S variant can be used as a model for Mtb GlgE. In conclusion, we designed a lead transition state inhibitor of GlgE, which will be instrumental in further elucidation of the enzymatic mechanism of Mtb GlgE.

Insights into neuronal cell metabolism using NMR spectroscopy: Uridyl diphosphate N-acetyl-glucosamine as a unique metabolic marker

Making the switch: Compounds 1 and 2 are used as metabolic markers for NMR detection. When neuronal cells switch to a glycolytic state, an uneven distribution of 13C in the N-acetyl group results, thus giving a mixture of the metabolites 1 and 2. It is therefore possible to monitor flux through different metabolic pathways, such as glycolysis, the tricarboxylic acid cycle, and the hexosamine biosynthetic pathway, using a single molecule.

LINKAGE MODIFIED OLIGOMERIC COMPOUNDS

The present invention provides gapped oligomeric compounds comprising from 1 to about 3 internucleoside linkages having one of formulas I to XVI. In certain embodiments, inclusion of from 1 to about 3 internucleoside linkages of one of formulas I to XVI, improves selectivity for a target RNA relative to an off target RNA. In certain embodiments, the improved selectivity also provides an improved toxicity profile. Certain such oligomeric compounds are useful for hybridizing to a complementary nucleic acid, including but not limited, to nucleic acids in a cell. In certain embodiments, hybridization results in modulation of the amount of activity or expression of the target nucleic acid in a cell.

In vitro cytotoxicity, DNA cleavage and SOD-mimic activity of copper(II) mixed-ligand quinolinonato complexes

Six mixed-ligand copper(II) complexes with the composition [Cu(qui)(L)]BF4·xH2O (1-6), where Hqui = 2-phenyl-3-hydroxy-4(1H)-quinolinone, L = 2,2?-bipyridine (bpy) (1), 1,10-phenanthroline (phen) (2), bis(2-pyridyl)amine (ambpy) (3), 5-methyl-1,10-phenanthroline (mphen) (4), 5-nitro-1,10-phenanthroline (nphen) (5) and bathophenanthroline (bphen) (6), were prepared, fully characterized and studied for their in vitro cytotoxicity on human osteosarcoma (HOS) and human breast adenocarcinoma (MCF7) cancer cell lines. The overall promising results of the cytotoxicity were found for all the complexes, while the best results were achieved for complex 6, with IC50 = 2.6 ± 0.8 muM (HOS), and 1.3 ± 0.5 muM (MCF7). The interactions of the Cu(II) complexes 1-6 with calf thymus DNA were investigated by the UV-visible spectral titration. An agarose-gel electrophoretic method of oxidative damage determination to circular plasmid pUC19 was used to assess the ability of the complexes to act as chemical nucleases. A high effectiveness of DNA cleavage was observed for 2, 4 and 5. In vitro antioxidative activity of the complexes was studied by the superoxide dismutase-mimic (SOD-mimic) method. The best result was afforded by complex 1 with IC50 = 4.7 ± 1.0 muM, which corresponds to 10.2% of the native Cu,Zn-SOD enzyme activity. The ability of the tested complexes to interact with sulfur-containing biomolecules (cysteine and reduced glutathione) at physiological levels was proved by electrospray-ionization mass spectrometry (ESI-MS).
