Bromoacetylfluorescein monoaldehyde as a fluorescence turn-on probe for cysteine over homocysteine and glutathione

A novel fluorescent probe possessing the two different functional groups of bromoacetyl ester and aldehyde functionality was designed as a selective chemodosimeter for cysteine (Cys). The initially nonfluorescent bromoacetyl-fluorescein monoaldehyde (3) was rapidly transformed into a strongly fluorescent molecule through the first nucleophilic substitution followed by the subsequent ester bond cleavage reactions by one Cys and the second oxazolidine formation reaction with another Cys. The molecular probe exhibited a rapid response toward Cys over homocysteine or glutathione owing to the favorable kinetic processes with Cys, of which property was successfully applied for live cell imaging with tunicamycin, an inducer of cytosolic Cys.

Aphanomyces pea root rot disease and control with special reference to impact of Brassicaceae cover crops

Pea root rot disease caused by the pathogen Aphanomyces euteiches deserves increased attention, since peas are an important cash crop and also improve the N balance in temperate agriculture. However, due to pea root rot it is difficult to cultivate peas as frequently and successfully as desired. In the search for biological measures to overcome this problem, attention has been drawn to the use of Brassicaceae plants as cover crops between main crops, since these can be effective catch crops for nutrients and also exert allelopathic effects. Many species within the Brassicaceae contain glucosinolates (GSLs). Their hydrolysis products, the volatile isothiocyanates (ITCs), have been shown to suppress soil-borne plant pathogens such as A. euteiches. In addition, Brassicaceae biomass releases water-soluble toxic substances such as oxazolidine-2-thione and supplies nutrients and organic matter. Overall, this influences the soil microbial community and the final suppression of pathogens. Due to the unpredictability of the control effect of Brassicaceae biomass incorporation into soil on the pathogen, there is a need to define the mechanisms behind suppression in the field situation. This review focuses on how incorporation of Brassicaceae biomass suppresses A. euteiches under field conditions and the effect on the emerging pea. Different factors influencing the severity of field pea (Pisum sativum L.) root rot disease are also discussed. One conclusion is that suppression of pea root rot depends on the quality and quantity of incorporated Brassicaceae biomass.

Molecular Motion in Frozen Phospholipid Bilayers in the Presence of Sucrose and Sorbitol Studied by the Spin-Echo EPR of Spin Labels

Electron spin echo (ESE) spectroscopy, a pulsed version of electron paramagnetic resonance (EPR), was applied to spin-labeled stearic acids in phospholipid bilayers hydrated in the presence of sucrose and sorbitol, which are known for their cryoprotective action on biological membranes. The phospholipids were 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC). Stearic acids were labeled by nitroxide 4,4-dimethyl-oxazolidine-1-oxyl (DOXYL) attached rigidly at either the 5th or 16th specific carbon positions. ESE detects fast stochastic small-angle restricted molecular rotations (stochastic molecular librations) with correlation times on the nanosecond timescale. These motions are believed to have the same nature as the anharmonic motions of hydrogen atoms in biological substances detected by neutron scattering and Mossbauer spectroscopy, which become active above 200 K. To ensure that the echo decays indeed originate from fast stochastic molecular librations, a three-pulse stimulated spin echo was employed. It was found that the presence of sucrose or sorbitol suppresses the observed molecular motions. The observed effect was nearly the same for both label positions, indicating that the motions are similarly suppressed near the bilayer surface and in the bilayer interior. This finding suggests non-specific interactions of sugars with bilayer surface, which are likely to influence only the bulk physical properties of hydrated membranes. The results obtained show the usefulness of spin-echo EPR of spin labels when applied to investigate the molecular mechanisms of action of cryoprotective agents on biological systems.

1,3-Dipolar Cycloaddition-Decarboxylation Reactions of an Azomethine Ylide with Isatoic Anhydrides: Formation of Novel Benzodiazepinones

A nonstabilized azomethine ylide reacts with a wide range of substituted isatoic anhydrides to afford novel 1,3-benzodiazepin-5-one derivatives, which are generally isolated In high yield. The transformations involve 1,3-dipolar cycloaddition reactions of the ylide with the anhydrides to give transient, and in a representative case spectroscopically observable, oxazolidine Intermediates that undergo ring-opening-decarboxylation-ring-closing reaction cascades to yield the 1,3-benzodiazepin-5-one products.

Nonlinear optical responses of self-assembled monolayers functionalized with indolino-oxazolidine photoswitches

A computational approach combining molecular dynamic simulations and density functional theory (DFT) calculations is implemented to evaluate the second-order nonlinear optical (NLO) responses of photoresponsive self-assembled monolayers (SAMs) based on indolino-oxazolidine molecular switches. These numerical simulations provide a complete atomistic picture of the morphology of the SAMs, revealing a high degree of positional disorder and an almost isotropic orientation of the chromophores. Subsequent DFT calculations, carried out to evaluate the average first hyperpolarizability of indolino-oxazolidine switches within the SAM, predict that the structural disorder does not significantly reduce the NLO contrast compared to that of the isolated molecules. Chromophores in the SAM can assume a limited number of specific conformations, due to the high rotational barrier that characterize the conjugated bonds along the indolino/oxazolidine-dyene-thiophene sequence. A notable exception is the rotation about the thiophene-thioalkyl bond, which is not only almost free, but also strongly correlated with the magnitude of the first hyperpolarizability. Controlling this rotation by chemical design could thus be a viable strategy to optimize the SAMs NLO response and the performance of photoresponsive devices based on indolino/oxazolidine switches.

Theoretical Perspectives on Redox Non-Innocent Oxazolidine N-Oxide Iron Nitroxide Complexes

One-electron redox processes in ligands that exhibit non-innocent behaviour invariably leads to the generation of radical species, which, when coupled with redox-active metal centres, can lead to strong magnetic exchange, ambiguous electronic structures and even spin crossover (SCO). We have chosen two iron complexes [Fe-II(L-center dot)(2)](BF4)(2) (1) and [Fe-III(L-)(2)](BPh4) (2) [with L-center dot = 4-dimethyl-2,2-di(2-pyridyl)oxazolidine N-oxide] as the basis for an extensive theoretical study to determine the influence and interplay of the strong magnetic exchange, the redox non-innocent behaviour and any possible spin transitions. A series of calculations established the low-spin character of the Fe in both the complexes and gave us valuable insight into the electronic structure of 1 and 2 along with their one- and two-electron reduced species. An attempt has been made to relate the bonding features to the energy difference between different spin states and to the influence of the exchange coupling on any possible SCO properties.

syn-Diastereoselective glycolate aldol addition reactions of an N(3)-(p-methoxyphenoxy)acetyloxazolidine-2-thione

An N-3-(p-methoxyphenoxy)acetyloxazolidine-2-thione has been synthesized and employed in glycolate asymmetric aldol addition reactions with aromatic and aliphatic aldehydes. It was determined that the titanium tetrachloride medicated aldol reaction afforded diastereoselectivities that ranged from 75:25 to 94:6 when the reaction was conducted at -78 degrees C. The absolute stereochemistry of the aldol adducts was determined by H-1 NMR spectroscopy and X-ray crystallography. The H-1 NMR spectra of the aldol adducts contained a signal (the a-proton of the glycolate position of the aldol side chain) that was highly deshielded due to conformational restriction about the N(3)-(p-methoxyphenoxy)acetyl side chain and the oxazolidine-2-thione auxiliary.

Depletion of M. tuberculosis GlmU from Infected Murine Lungs Effects the Clearance of the Pathogen

M. tuberculosis N-acetyl-glucosamine-1-phosphate uridyltransferase (GlmU(Mtb)) is a bifunctional enzyme engaged in the synthesis of two metabolic intermediates N-acetylglucosamine-1-phosphate (GlcNAc-1-P) and UDP-GlcNAc, catalyzed by the C- and N-terminal domains respectively. UDP-GlcNAc is a key metabolite essential for the synthesis of peptidoglycan, disaccharide linker, arabinogalactan and mycothiols. While glmU(Mtb) was predicted to be an essential gene, till date the role of GlmU(Mtb) in modulating the in vitro growth of Mtb or its role in survival of pathogen ex vivo / in vivo have not been deciphered. Here we present the results of a comprehensive study dissecting the role of GlmU(Mtb) in arbitrating the survival of the pathogen both in vitro and in vivo. We find that absence of GlmU(Mtb) leads to extensive perturbation of bacterial morphology and substantial reduction in cell wall thickness under normoxic as well as hypoxic conditions. Complementation studies show that the acetyl-and uridyl-transferase activities of GlmU(Mtb) are independently essential for bacterial survival in vitro, and GlmU(Mtb) is also found to be essential for mycobacterial survival in THP-1 cells as well as in guinea pigs. Depletion of GlmU(Mtb) from infected murine lungs, four weeks post infection, led to significant reduction in the bacillary load. The administration of Oxa33, a novel oxazolidine derivative that specifically inhibits GlmU(Mtb), to infected mice resulted in significant decrease in the bacillary load. Thus our study establishes GlmU(Mtb) as a strong candidate for intervention measures against established tuberculosis infections.
