THE USE OF FLUOROPHORE-CONTAINING SPIN TRAPS AS POTENTIAL PROBES TO LOCALIZE FREE-RADICALS IN CELLS WITH FLUORESCENCE IMAGING METHODS

Central to the study of free radical processes is the ability to identify and localize their cellular site of formation. Under the best of experimental conditions, spin trapping/ESR spectroscopy can only characterize intracellular production of specific free radicals and confocal microscopy can only localize the site of their formation. In this article, we report on the development of a fluorophore-containing nitrone, alpha-[4-[5-((2-carboxy)phenyl)-5-hydroxy-4-oxo-3-phenyl)-2-pyrrolin-1-yl]phenyl]-N-(tert-butyl)nitrone sodium salt (4).(3) This nitrone (4) reacts with alpha-hydroxyethyl radical with a second order rate constant of 1.7 x 10(5) M(-1) s(-1) to give a characteristic ESR spectrum. However, we were unable to decrease the fluorescence emission, due in part to the small concentration of nitroxide generated from the reaction of alpha-hydroxyethyl radical with nitrone (4). Using the fluorophore-containing nitroxide (7) as a model, we found that only 12% of the nitroxide needs to be reduced to give an almost 400% increase in the fluorescent emission of (7). Our findings suggest new approaches to the development of various fluorophore-containing nitrones that can both characterize specific free radicals and localize their site of intracellular formation.

A second-generation synthesis of scalemic 3,5,5-trisubstituted pyrrolin-4-ones: Incorporation of functionalized amino acid side-chains

To access mimics of peptidal beta-strands (1), scalemic 3,5,5-trisubstituted pyrrolin-4-ones bearing the tyrosine, serine, and lysine side-chains have been generated via cyclization of metalated imino esters and deprotection. The functionalized imino esters were prepared by asymmetric alkylation of a common oxazolidinone precursor (2) derived from L-prenylglycine. (C) 1997 Elsevier Science Ltd.

Practical Synthesis of alpha-Trifluoromethylated Pyridines Based on Regioselective Cobalt-Catalyzed [2+2+2] Cycloaddition using Trifluoromethylated Diynes with Nitriles

Regioselective cobalt-catalyzed [2+2+2] cycloaddition using fluorine-containing diynes with nitriles was described. Cycloaddition of fluorinated diynes with nitriles under the influence of CoCl2(phen), zinc bromide, and zinc dust in dichloroethane at 80 degrees C for 3 h took place smoothly, exclusively affording the corresponding alpha-fluoroalkylated pyridines in excellent yields. In addition, dinitriles as substrate were also found to be suitable for this reaction, giving the corresponding fluoroalkylated bipyridine derivatives in excellent yields.

Cu(OAc)(2)-Triggered Cascade Reaction of Malonate-Tethered Acyl Oximes with Indoles, Indole-2-alcohols, and Indole-2-carboxamides

A Cu(OAc)(2)-promoted cascade reaction of malonate-tetherd acyl oximes with indoles, indole-2-alcohols, or indole-2-carboxmides provides facile access to polysubstituted 3-pyrrolin-2-ones. The reaction features the generation of two adjacent electrophilic centers at the same time as cyclization to lactam. The subsequent double addition with nucleophiles followed by oxidation realizes the difunctionalization of the imine sp(2)-carbon and the adjacent alpha-sp(3)-carbon.

Preparation of precursors for the synthesis of analogues of rhazinilam

Rhazinilam a structurally relatively simple tetracyclic natural product exerts interesting anticancer activities in vitro, which are difficult to reproduce in vivo. Based on the findings accumulated during the synthetic efforts and on the known metabolic sensitivity towards oxidation and acids a modified structural analogue of rhazinilam is proposed. A novel convergent approach towards the heterocyclic biaryl unit is described. The key sequence for the construction of 7 is the Mukaiyama crossed aldol reaction followed by the Staudinger reaction. Using known N-alkylation procedures the introduction of the side chains onto the 3-pyrrolin-2-one intermediate 2 needed for the construction of the tetracycle could not be achieved.

Failure analysis of LiNi0.83Co0.12Mn0.05O2/graphite-SiOx pouch batteries cycled at high temperature

The combination of Ni-rich layered oxide and graphite-SiOx is regarded as a high-energy-density system for the lithium-ion power batteries. It is significant to elaborate the failure mechanism of the two materials in full batteries, especially at high temperature. In this study, the failure behavior of LiNi0.83Co0.12Mn0.05O2/graphite-SiOx pouch batteries (>= 50 Ah) cycled at 45 degrees C has been studied by using the non-destructive electrochemical methods and physico-chemical methods for the cathode and anode materials. Compared with the failure mechanism of lithium-ion batteries cycled at room temperature, it is more inclined to occur at high temperature that transition metal ions dissolve out from cathode and deposit on the anode, electrolyte decomposes, and solid electrolyte interphase grows. The resulting phenomena show that the cathode deterioration is slight, and the anode degradation is the main factor of pouch battery degradation. After failure analysis, the concentrationgradient NCM cathode and nitrile-containing electrolyte additive are assembled into the pouch batteries, and the capacity retention increases from 75.24% (pristine batteries at 280 cycles) to 83.44% (improved batteries at 1500 cycles). Therefore, we suggest that power batteries operating at high temperature should be with minimized transition metal dissolution of cathode materials and stable solid electrolyte interphase.

Effect of exogenous and endogenous antioxidants on 3-nitropropionic acid-induced in vivo oxidative stress and striatal lesions: Insights into Huntington’s disease

3-Nitropropionic acid (3-NP) is an irreversible inhibitor of complex ii in the mitochondria, 3-NP toxicity has gained acceptance as an animal model of Huntington’s disease (HD). In the present study, we confirmed that rats injected with 3-NP (20 mg/kg, i.p., daily for 4 days) exhibit increased oxidative stress in both striatum and cortical synaptosomes as well as lesions in the striatum, Synaptosomal membrane proteins from rats injected with 3-NP exhibited a decrease in W/S ratio, the relevant electron paramagnetic resonance (EPR) parameter used to determine levels of protein oxidation, and western blot analysis for protein carbonyls revealed direct evidence of increased synaptosomal protein oxidation. Treatment of rats with the brain-accessible free radical spin trap 5-diethoxyphosphoryl-5-methyl-1-pyrrolin N-oxide (DEPMPO; 30 mg/kg, i.p., daily 2 h before 3-NP injection) or with N-acetylcysteine (NAC; 100 mg/kg, i.p,, daily 2 h before 3-NP injection), a known glutathione precursor, before 3-NP treatments protects against oxidative damage induced by 3-NP as measured by EPR and western blot analysis for protein carbonyls, Furthermore, both DEPMPO and NAC treatments before 3-NP administration significantly reduce striatal lesion volumes. These data suggest oxidative damage is a prerequisite for striatal lesion formation and that antioxidant treatment may be a useful therapeutic strategy against 3-NP neurotoxicity and perhaps against HD as well.
