Children learn through play, and they learn more than adults might expect. 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. 499-40-1, C12H22O11. A document type is Article, introducing its new discovery., category: Tetrahydropyrans

The cobalt(II) complexes with the quinolone antimicrobial agent enrofloxacin (Herx) in the presence of the nitrogen-donor heterocyclic ligands pyridine (py), 2,2?-bipyridylamine (bipyam), 1,10-phenanthroline (phen), 2,2?-bipyridine (bipy) or the oxygen-donor ligand N,N-dimethylformamide (DMF) were synthesized and characterized. The crystal structures of complexes [Co(erx)2(py)2]·MeOH·6H2O and [Co(erx)2(bipyam)]·4.5MeOH·1.25H2O were determined by X-ray crystallography. The deprotonated enrofloxacinato ligands are bidentately bound to cobalt(II) ion through the pyridone oxygen and a carboxylato oxygen. The antimicrobial activity of the complexes was tested against five different microorganisms (Escherichia coli XL1, Xanthomonas campestris ATCC33013, Staphylococcus aureus ATCC29213, Bacillus cereus ATCC11778 and Bacillus subtilis ATCC6633) and the complexes were more active than free Herx. The binding of the complexes to calf-thymus DNA (CT DNA) was monitored by spectroscopic techniques, viscosity measurements, cyclic voltammetry and by mobility shift experiments in agarose gel electrophoresis with CT DNA and plasmid DNA (pDNA). All complexes exhibited a preference for binding to the supercoiled structure of the pDNA. The ability of the complexes to displace ethidium bromide (EB) from the EB-DNA complex was also investigated. The experiments indicated intercalation as the most possible mode and the DNA-binding strength of the complexes were also calculated. The complexes bind to human or bovine serum albumin protein exhibiting relatively high binding constant values.

Electric Literature of 14215-68-0, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6.

The beta-N-acetylhexosaminidase from Penicillium oxalicum (PoHex; EC 3.2.1.52) is a fungal glycosidase with an outstandingly high GalNAcase/GlcNAcase activity ratio. It has a remarkable synthetic capability and can process carbohydrates functionalized at various positions. However, the production in the native fungal host is lengthy, unselective and purification from the fungal medium is complicated and low yielding. We present here a novel production method of this enzyme in the eukaryotic host of Pichia pastoris, followed by elegant one-step purification to homogeneity. The resulting recombinant enzyme has improved biochemical and catalytic properties compared to the fungal wild type. Its good production yield (11 mg/400 mL cultivation medium) greatly expands the scope of synthetic applications. We further demonstrate the synthetic utility and broad acceptor specificity of recombinant PoHex in the glycosylation of a series of challenging acceptors with varying structural architectures, namely secondary and tertiary hydroxyl, aldoxime and a poly-hydroxylated compound.

Zinc complexes with the third-generation quinolone antibacterial drugs levofloxacin and sparfloxacin have been synthesized and characterized. The deprotonated quinolones act as bidentate ligands coordinated to zinc ion through the pyridone and a carboxylato oxygen atom. The crystal structures of [bis(aqua)bis(levofloxacinato)zinc(ii)], 1, and [bis(sparfloxacinato)(1,10- phenanthroline)zinc(ii)], 3, have been determined by X-ray crystallography. The biological activity of the complexes has been evaluated by examining their ability to bind to calf-thymus DNA (CT DNA) by UV spectroscopy and viscosity measurements. UV studies of the interaction of the complexes with DNA have revealed that they can bind to CT DNA probably by the intercalative binding mode which has also been verified by DNA solution viscosity measurements. The DNA binding constants have been also calculated. A competitive study with ethidium bromide (EB) showed that the complexes exhibit the ability to displace the DNA-bound EB indicating that they bind to DNA in strong competition with EB for the intercalative binding site. The interaction of the complexes with human and bovine serum albumin proteins has been studied by fluorescence spectroscopy showing that the complexes exhibit good binding propensity to these proteins having relatively high binding constant values. The biological properties of the complexes have been evaluated in comparison to the previously reported Zn(ii) complexes with the first- and second-generation quinolones oxolinic acid and enrofloxacin.

The known compound 1,2,5-thiadiazole-3,4-dicarbonitrile, 1a preferentially forms mono addition compounds 3, but also bis-addition compounds 4 with oxygen, nitrogen and sulfur nucleophiles. One preparation of 1a produced bis<4-cyano-1,2,5-thiadiazol-3-ylmethyl(imino)>amine 2 as a minor product. The structure of compound 2, the facile formation of triazine 5 and the monocyclic structures of 3 and 4 indicate extensive stereoelectronic interactions between vicinal substituents of 1,2,5-thiadiazole. A bicyclic diimino imide was not formed from 1a in sulfur- or methoxide-catalysed reactions with ammonia in methanol.
