Novel purely organic conductor with an aminoxyl radical, alpha-(BEDT-TTF)(2)(PO-CONHCH2SO3)-2H(2)O (PO=2,2,5,5-tetramethyl-3-pyrrolin-1-oxyl free radical)

A novel bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF)-based salt with an aminoxyl radical 2,2,5,5-tetramethyl-3-pyrrolin-l-oxyl (PO) has been prepared. The salt has alpha-type 2-D conducting sheets and is a semiconductor with rho(RT) = 26 Omega center dot cm and E-a = 0.31 eV. The temperature dependence of the magnetic susceptibility suggests that both the aminoxyl radical and the BEDT-TTF layer have local spin moments at room temperature.

Bacterial profiles and volatile flavor compounds in commercial Suancai with varying salt concentration from Northeastern China

Suancai, a popular traditional fermented cabbage in northeast China, is commonly prepared by the spontaneous fermentation process at a certain salt concentration. The salt can affect the metabolites by affecting the microorganisms during Suancai fermentation. The bacterial community and volatile flavor compounds in commercial Suancai from different regions of Northeastern China at different salt concentrations were investigated using next-generation sequencing and GC-MS. Firmicutes and Cyanobacteria were the dominant phyla in the commercial Suancai, and Lactobacillus, Pediococcus, and Leuconostoc were the dominant genera. Among them, Lactobacillus and Pediococcus were considered as the biomarkers of the low and high salt Suncai, respectively. Eighty-five volatile flavor compounds were detected, and HS exhibited higher contents of volatile flavor compounds than LS. Based on the results of correlation analysis, Pediococcus were highly correlated with the alcohols and nitriles in Suancai. The contents of alcohols and nitriles significantly increased in the Suancai, fermented by Pediococcus pentosaceus. The co-inoculated fermentation of Lactobacillus plantarum and P. pentosaceus could increase the concentrations of alcohols, esters, aldehydes, hydrocarbons, and nitriles in Suancai. This study provides a perspective for understanding the ecology of Suancai fermentation and facilitating the fermentation with multispecies inoculation fermentation at an appropriate salt concentration.

Racemic synthesis of the new antibiotic tetramic acid reutericyclin

The synthesis of the new bacteriocidal compound reutericyclin, 3-acetyl-1-(2-trans-decenoyl)-2-hydroxy-5-isobutyl-Delta(2)-pyrrolin-4-one, is performed by coupling of N-(2-trans-decenoyl)-L-leucine to Meldrum’s acid followed by cyclization. The resulting N-acylated tetramic acid is directly C-acetylated in position 3. HPLC-purification on RP-C-18 gave racemic reutericyclin in high purity. 2D-NMR and FT-ICR-MS data are identical with those of natural reutericyclin.

A commonly used spin label: S-(2,2,5,5-tetramethyl-1-oxyl-Delta(3)-pyrrolin-3-ylmethyl) methanethiosulfonate

The title compound, C(10)H(18)NO(3)S(2), which finds application as a spin label, has triclinic (P (1) over bar) symmetry at 100 (2) K with two independent molecules in the asymmetric unit. Both molecules are very similar with respect to bond lengths and angles, but molecule 2 shows disordering of its side chain. The pyrroline rings differ slightly with respect to the position of the NO group, which in both cases are sterically shielded by the surrounding methyl groups. The crystal structure of the title compound represents the first example of a 2,2,5,5-tetramethyl-1-oxyl-Delta(3)-pyrroline derivative with a side chain at the double bond which is linked to it through an sp(3)-hybridized C atom. In the solid state, the side chain adopts a conformation with the methyl group above/below the pyrroline ring and a H atom directed towards a C atom of the double bond. The disordered side chain of molecule 2 represents a second conformation with low potential energy. Both molecules exhibit planar chirality, but in the solid state both pairs of stereoisomers are present. These four stereoisomers are stacked one behind the other in four different columns, denoted A, A’, B and B’, the angle between the vectors of the N-O bonds in columns A and B being 80.38 (8)circle.

Nitroxide spin probes for magnetic resonance characterization of ordered systems

Stable free radicals belonging to different classes have been synthesized in view of potential applications in studies of organized systems. Among them a new pyrroline nitroxide with a high fluorine content, 2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy-3-[(1H,1H-perfluoro-1-octoxy)carbonyl] (3), apt to probe the hydrophobic perfluoro-rich domains inside macroaggregates, has been prepared by a rarely encountered approach namely the spin-labelling of the very cosurfactant participating in the self-assembling process. Emphasis has then been laid upon the synthesis of further stable free radicals from the group of substituted nitronyl nitroxides. A general experimental procedure has been adapted according to the nature of the 2-substituent, resulting in a series of nitronyl nitroxides with a wide range of hydrophobicity and showing spectral parameters in good agreement with literature values. Using the spin probe-electron spin resonance technique, 3 and the 1-H-imidazol-1-yloxy-4, 5-dihydro-4,4,5, 5-tetramethyl-2-ethyl-3-oxide (7, R = C2H5) or the 1-H-imidazol-1-yloxy-4,5-dihydro-4,4,5,5 (7, R = C11H23) have been applied in ESR investigations on vesicle phases of a zwitterionic surfactant (TDMAO)/perfluorocosurfactant (PFC) system and on Triton X-100 reverse micelles, respectively. While spin probe 3 proved to be insensitive to differences between the charged and uncharged phases, probes 7 were able to detect changes in the micelle micropolarity induced by hydration. The results corroborate well with previous W measurements in the Triton X-100 system using the same probes 7. (C) 2001 Elsevier Science B.V. All rights reserved.

STAUROSPORINE INHIBITS INOSITOL PHOSPHATE FORMATION IN BOVINE ADRENAL-MEDULLARY CELLS

The effect of protein kinase C activators and inhibitors on histamine-stimulated phospholipase C in bovine adrenal medullary cells has been investigated. The protein kinase C activators, phorbol 12,13-dibutyrate (PDB) or sn-1,2-dioctanoylglycerol (DOG), inhibited histamine-stimulation of phospholipase C. This inhibition was prevented by the protein kinase C-selective inhibitor Ro 31-8220 (3-{1-[3-(2-isothioureido) propyl]indol-3-yl}-4-(1-methylindol-3-yl)-3-pyrrolin-2,5-dione) but not the broad spectrum protein kinase inhibitor staurosporine. Indeed staurosporine on its own inhibited both the histamine-stimulated response and, in permeabilized cells, phospholipase C activated by Ca2+. Staurosporine inhibition of phospholipase C is unlikely to be mediated via protein kinase A or Ca2+/calmodulin-dependent protein kinase because it was not reproduced by selective inhibition of these kinases. Staurosporine treatment, however, reduced inositol phospholipid levels in stimulated cells. Thus staurosporine and Ro 31-8220, two widely used protein kinase C inhibitors, have quite different effects on phospholipase C activation. Furthermore, staurosporine may cause this inhibition through a reduction in the level of phospholipase C substrate.

Organocatalyzed Asymmetric Mannich Reaction: An Update

The Mannich reaction is a multicomponent reaction resulting in aminoalkylation of an acidic proton placed next to a carbonyl functional group. It involves an appropriate carbonyl compound, such as formaldehyde and a primary or secondary amine or ammonia. The final product is a beta-amino-carbonyl compound known as a Mannich base. Reactions between aldimines and alpha-methylene carbonyls are also considered as Mannich reaction since these imines are generated from the reaction of amines and aldehydes. It comprises the reaction of primary or secondary amines or ammonia, formaldehyde and appropriate alpha-CH-acidic compounds (nucleophiles) such as carbonyl compounds having alpha-CH-acidic, nitriles, acetylenes, aliphatic nitro compounds, alpha-alkyl-pyridines or imines. Owing to the development of asymmetric organocatalysis, reports on asymmetric Mannich reaction have been drastically increased. The asymmetric Mannich reaction offers access to enantioenriched beta-amino ketones or beta-amino aldehydes, which are present as a scaffold in several natural products. Organocatalysts have been developed not only as a supplement to metal-catalyzed reactions or to biocatalysis, but nowadays, they are extensively used for the synthesis of various optically pure compounds that could not be achieved via metal- or biocatalyzed reactions. In this review, we try to update the advances in organocatalyzed asymmetric Mannich reactions, covering the recent advances of the subject from 2008 to date.
