Detection of CH3C3N in Titan’s Atmosphere

Titan harbors a dense, organic-rich atmosphere primarily composed of N-2 and CH4, with lesser amounts of hydrocarbons and nitrogen-bearing species. As a result of high-sensitivity observations by the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 6 (similar to 230-272 GHz), we obtained the first spectroscopic detection of CH3C3N (methylcyanoacetylene or cyanopropyne) in Titan’s atmosphere through the observation of seven transitions in the J = 64 -> 63 and J = 62 -> 61 rotational bands. The presence of CH3C3N on Titan was suggested by the Cassini Ion and Neutral Mass Spectrometer detection of its protonated form: C4H3NH+, but the atmospheric abundance of the associated (deprotonated) neutral product is not well constrained due to the lack of appropriate laboratory reaction data. Here, we derive the column density of CH3C3N to be (3.8-5.7).x.10(12) cm(-2) based on radiative transfer models sensitive to altitudes above 400 km Titan’s middle atmosphere. When compared with laboratory and photochemical model results, the detection of methylcyanoacetylene provides important constraints for the determination of the associated production pathways (such as those involving CN, CCN, and hydrocarbons), and reaction rate coefficients. These results also further demonstrate the importance of ALMA and (sub)millimeter spectroscopy for future investigations of Titan’s organic inventory and atmospheric chemistry, as CH3C3N marks the heaviest polar molecule detected spectroscopically in Titan’s atmosphere to date.

Rotational correlation times of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin label with respect to heme and nonheme proteins

Noncovalent spin labeled proteins (ovalbumin, bovine serum albumin, hemoglobin, and cytochrome c) were investigated in order to follow the different type of interactions between the nitroxide radical of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin label and functional groups of heme and nonheme proteins as well as the pH influence on molecular motion of the label with respect to these proteins. EPR spectra were recorded at room temperature and the computer simulation analysis of spectra was made in order to obtain the magnetic parameters. Noncovalent labeling of proteins can give valuable information on the magnetic interaction between the label molecule and the paramagnetic center of the proteins. The relevance of this interaction can be obtained from line shape analysis: computer simulations for nonheme proteins assume a Gaussian line shape, whereas for heme proteins, a weighted sum of Lorentzian and Gaussian components is assumed. In the framework of the moderate jump diffusion model for rotational diffusion, the rotational correlation time is strongly influenced by pH, because of the electrostatic interactions and hydrogen bonding.

Photocatalytic Conversion of Benzyl Alcohols/Methyl Arenes to Aryl Nitriles via H-Abstraction by Azide Radical

This report presents the visible-light-assisted synthesis of aryl nitriles from easily accessible alcohols or methyl arenes in the presence of O-2. Organic photoredox catalyst, 4CzIPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene), induces single electron transfer (SET) from azide N(3)(-)and generates azide radical N-3(.).The photogenerated N(3)(.)abstracts H atom from alpha-C-H bond of benzylic system, which provides aldehyde and hydrazoic acid (HN3) in situ. This reaction subsequently forms azido alcohol intermediate that transforms into nitrile with the assistance of triflic acid (Bronsted acid). A range of alcohols and methyl arenes successfully underwent cyanation at room temperature with good to excellent yields and showed good functional group tolerance.

A slow relaxing species for molecular spin devices: EPR characterization of static and dynamic magnetic properties of a nitronyl nitroxide radical

Nitronyl nitroxides (NitR) are a family of persistent radicals widely used in molecular magnetism and recently suggested as potential candidates for spintronic applications. In this paper we characterize by X-and W-band Electron Paramagnetic Resonance (EPR) spectroscopy the new radical S-4-(nitronyl nitroxide) benzyl ethanethioate (NitSAc) designed for assembling on Au surfaces. We determined the radical magnetic tensors and studied by X-band pulse EPR its spin relaxation behaviour in fluid and glassy solutions of toluene. A comparison with the well known nitroxide 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-oxyl (CTPO) is afforded. The advantages of using NitSAc in technological applications are discussed on the basis of the slow spin relaxation demonstrated by this study.

MODULATING ACTION OF VITAMIN C ON THE CYTOTOXIC EFFECT OF MYOSMINE

Myosmine (3-(1-pyrrolin-2-yl)pyridine) is an alkaloid found in tobacco as well as in various foods, fruits and vegetables. Myosmine has recently been suspected to be a tobacco-independent carcinogenic source connected to the increase in incidence of esophageal adenocarcinoma. It has been shown that reactions of nitrosation and peroxidation of myosmine take part in its metabolic activation and leads to the formation of the esophageal carcinogens N’-nitrosonornicotine and 4-hydroxy-1-(3-pyridy1)-1-butanone. Increased cancerogenic potential of myosmine may be expected when the oxidative stress in the cell is enhanced. In order to examine the relationship between the oxidative status of the cells and the inhibitory action of myosmine on the cell growth we studied the combined effect of the antioxidant vitamin C and myosmine on cell proliferation as well as on the cell cycle of murine erythroleukemia (MEL) cells. Protective effect of vitamin C was found at incubation time of 48 hours. It was clearly observed that vitamin C had reduced the toxicity of myosmine in a wide range of concentrations. In order to see how cell cycle is affected in the presence of vitamin C and myosmine we conducted flow cytometric analysis. A combination of vitamin C with 100 mu M myosmine resulted in elimination of the effect of myosmine, respectively the histogram was almost identical to that of the control untreated cells. This result showed that the antioxidant had reduced the influence of myosmine on the cell cycle of MEL. At higher myosmine concentration (200 mu M) the addition of vitamin C reduced the amount of hypoploid cells almost in half. This could be connected with the smaller fraction of apoptotic cells. The conclusion can be drawn that vitamin C may protect cells from the cytotoxic effect of myosmine.

Ligand-controlled self-assembly of Ag(I) complexes with cyano-containing ligands and their tunable antimicrobial activities

Three cyano-containing ligands with varied size and shape, i.e. 1,4-dicyano benzene (1,4-dcb), 4,4′-biphenyldicarbonitrile (bpcn) and p-phenylenediacetonitrile (p-phda), were selected as ligands to self-assemble with AgCF3COO and 4,4′-dihydroxyoctafluorobipheny (ofbp) affording five new compounds. Complexes 1-3 ([Ag-2(CF3COO)2(1,4-dcb)(S)]center dot 2ofbp center dot H2O, 1, S=benzene, 2, S=toluene 3, S= m-xylene) were synthesized by the same linear spacer (1,4-dcb) in different solvents, and they exhibit similar 2D networks assembled by 1,4-dcb ligand bridging with 1D chains composing of anions and different coordinating solvents. Complex 4 ([Ag-2(CF3COO)(2)(bpcn)(2)]center dot C6H6 center dot 2ofbp center dot H2O) was isolated by replacing 1,4-dcb to the longer linear spacer (bpcn) however it shows a quite different 1D chain structure from those of 1-3. Further changing ligand to p-phda resulted only compound c as a co-crystal of p-phda and of bp. These totally different crystal structures suggest the ligand-controlled self-assembly processes. The followed antimicrobial assay results demonstrate that all complexes have effective antimicrobial activities with broad spectra. They exhibit excellent antimicrobial activities with low MICs towards both Gram-negative bacteria, Gram-positive bacteria and yeast. Especially, they illustrate encouraging antibacterial activities against antibiotic resistant bacteria (P. aeruginosa). It’s found that these frameworks have discriminating capacities to release Ag+ ions in water sustainably. Complex 4 demonstrated the best antimicrobial efficacy among five complexes. It’s revealed that the ligand exchangeability plays an important role in the anti-microbial activities. The lower concentration of Ag+ ions release of complex 3 is attributed to its compact packing structure on the basis of structure-property discussions.
