Candida antarctica lipase B (Novozym 435)-catalyzed transesterification on methyl (±)-3,4-di-O-acetyl-5-O-(tert-butyldimethyl)silyl-3-epi-shikimate worked highly regio- and enantioselective manner. Only (3R,4S,5S)-isomer reacted with an E value over 500, exclusively on C-3 acetate. The regio- a...
One is not like the other: The title approach proceeds by stepwise coupling of three relatively simple substrates. Three natural product‐inspired agents are described, one of which has natural product‐like toxicity for HeLa and MCF7 cells. It is isoform‐selective, thus targeting Hsp90α/β ov...
We reported previously that a 3.6-kb double-stranded RNA, designated as M2, is associated with hypovirulence in the Rhizoctonia solani isolate Rhs1A1 and proposed that the M2-encoded putative polypeptide A (pA) might interfere with the regulation of the quinate and shikimate pathways. In this st...
Nausea and vomiting can occur in Parkinson's disease (PD) patients initiated on apomorphine subcutaneous injections and antiemetic prophylaxis is recommended per product labeling. Data suggest long-term antiemetic prophylaxis may not be needed, although this has not been systematically studied.W...
Two cyanogenic glucosides, prunasin (2-β-glucopyranosyloxy-2-phyenylacetonitrile) and its malonic acid conjugate, pruasin 6'-malonate, have been isolated from the above ground parts of Lotononis fruticoides and L. aff. falcata (Fabaceae). The compounds were identified by means of 1 H an...
In greenhouse experiments, Nemaguard peach seedlings were irrigated with nutrient solutions containing NO 3 - :NH 4 + ratios of 100:0, 75:25, 50:50, 25:75 and 0:100, and Al concentrations of 0 or 1mM. Eight weeks of treatment with 1mM aluminum caused severe reductions in ...
IntroductionPrunus serotina is native to North America but has been invasively introduced in Europe since the seventeenth century. This plant contains cyanogenic glycosides that are believed to be related to its success as an invasive plant. For these compounds, chromatographic‐ or spectrometri...
Structural features, the crystal packing, and the proton conductivity of a series of hydrates and ammonium salts of 4-nitrobenzenesulfonic acid were studied. It was shown that infinite cation associates containing the onium moiety are responsible for a substantial increase in the proton conducti...
Aluminium electrodeposition on carbon steel is performed potentiostatically and galvanostatically from aluminium chloride — trimethylphenylammonium chloride room temperature ionic liquid (RTIL). The influence of the electrochemical parameters and temperature on the coating composition, morpholo...
The title compound, {(C9H14N)2[Cu3Cl8]}n, consists of parallel chains of alternating quasiplanar Cu2Cl6 and planar CuCl4 complexes separated by trimethylphenylammonium cations. Both inorganic complexes possess inversion symmetry. Pairs of neighboring chloride ions of the CuCl4 complex each form ...
This work presents the studies of the nucleation processes and surface morphology of aluminium electrodeposits obtained on tungsten (W) and aluminium (Al) electrodes from 2:1 molar ratio aluminium chloride (AlCl 3 )–trimethylphenylammonium chloride (TMPAC) ionic liquids. The deposition ...
Field trials were conducted with each synthetic enantiomer (>98% ee) and blends of the two synthetic enantiomers of the female-produced sex pheromone (10,14-dimethylpentadecyl isobutyrate) of the tea tussock moth, Euproctis pseudoconspersa. Male moths were attracted to each enantiomer alone and ...
Isobaric vapor–liquid equilibrium data have been experimentally determined at 101.3kPa for the binary systems ethanol+ethyl lactate, isopropanol+isopropyl lactate and n-butanol+n-butyl lactate. No azeotrope was found in any of the systems. All the experimental data reported were thermodynamical...
Semi‐crystalline AB‐copolymer networks from oligo[(ε‐caprolactone)‐co‐glycolide]dimethacrylates and n‐butylacrylate have recently been shown to exhibit a shape‐memory functionality, which may be used for self‐deploying and anchoring of implants. In this study, a family of such materials...
The objective of this study was to investigate the effects of 6 weeks of food restriction (FR) on sarcolemmal lactate transport in rats. The daily food consumption of rats was monitored for 10 days, after which they were assigned to either a control group (CTL, n = 7) that consumed food ad libit...
Semiorganic nonlinear optical crystal of L-Glutamic acid hydrochloride (LGHC) was grown from aqueous solution by slow evaporation technique. Single crystal X-ray Diffraction analysis confirms that LGHC crystallizes in orthorhombic system with noncentrosymmetric space group P212121. The powder X-...
Single crystals of l-Glutamic acid hydrochloride (LGHCl) were grown by slow evaporation solution technique and good crystalline perfection was confirmed by Powder X-ray diffraction studies. The complete vibrational studies of the compound were analyzed by FT-IR, FT-Raman and UV–visible spectra ...
One of the halide derivatives of L‐glutamic acid which was identified as a semiorganic nonlinear optical material, L‐glutamic acid hydrochloride [HOOC(CH2)2CH(NH2)COOH.HCl], was grown as bulk single crystal and its significant properties were characterized. The stoichiometric title compound wa...
The iron chelator, deferoxamine mesylate (DFO), has shown neuroprotective effects, mediated via suppression of iron-induced hydroxyl radical formation, in various animal models of ischemic and hemorrhagic stroke. Therefore, the objective of this study was to investigate whether DFO can exert sim...
Staphylococcus aureus is a leading cause of bacterial infections. Strains of community-associated methicillin-resistant S. aureus (CA-MRSA), such as USA300, display enhanced virulence and fitness. Patients suffering from iron overload diseases often undergo iron chelation therapy with deferoxami...
