Application of analytical pyrolysis to gain insights into proteins of condensed corn distillers solubles from selective milling technology

Present study evaluates the analytical pyrolysis to unravel the pyrolysate compounds (PyCs), protein & glycosylation indicators in a protein fraction (PF) from condensed corn distillers solubles (CCDS) of novel selective milling technology. Besides, quadratic and linear corre-lations using protein content (%) by Dumas method, toluene signature PyC, and elemental nitrogen (%) were developed. Pyrolysis was performed at temperature of 400 degrees C, where most of the PyCs released from proteins in a lignin-free PF instead of other constituents. The p cresol and methyl 9,12-octadecadienoate were found with the highest area% of 3.2 and 19.3 in PF and CCDS, respectively. Protein derived PyCs such as nitrogen heterocyclics, amines & amides and nitriles were examined 63.93%, 61.90% and 70% greater in PF than CCDS. Moreover, the indicators of protein were toluene, p-cresol, phenol, phenylacetonitrile, 4vinylphenol, whereas that of glycosylated protein were methyl mercaptan, furan derivatives, and hexahydro-3-(phenylmethyl) pyrrolo [1, 2 a] pyrazine-1,4-dione. The absence of diketopiperazines provided evidence of crosslinking and aggregation of protein. The values of the protein content obtained from the quadratic model and Dumas method were found to be statistically non-significant (p < 0.05) imply the model validity. The results would aid in bioconversion of CCDS to future value-added products. (C) 2020 Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.

Acceptorless dehydrogenation of amines to nitriles catalyzed by N-heterocyclic carbene-nitrogen-phosphine chelated bimetallic ruthenium (II) complex

We have developed a clean, atom-economical and environmentally friendly route for acceptorless dehydrogenation of amines to nitriles by combining a new dual N-heterocyclic carbene-nitrogen-phosphine ligand R(CNP)(2) (R = o-xylyl) with a ruthenium precursor [RuCl2(eta(6)-C6H6)](2). In this system, the electronic and steric factors of amines had a negligible influence on the reaction and a broad range of functional groups were well tolerated. All of the investigated amines could be converted to nitriles in good yield of up to 99% with excellent selectivity. The unprecedented catalytic performance of this system is attributed to the synergistic effect of two ruthenium centers chelated by R(CNP)(2) and a plausible reaction mechanism is proposed according to the active species found via in situ NMR and HRMS.

Switch-On Diketopyrrolopyrrole-Based Chemosensors for Cations Possessing Lewis Acid Character

For the first time diketopyrrolopyrroles (DPPs) have been synthesized directly from nitriles possessing (aza)crown ethers leading to macrocycle-dye hybrids. Depending on the nature of the linkage between DPP and macrocyclic ring, various coordination effects are found. The strong interaction of the cations possessing Lewis acid character such as Li+, Mg2+ and Zn2+ with 2-aminopyridin-4-yl-DPPs, leading to a bathochromic shift of both emission and absorption, as well as to strong enhancement of fluorescence was rationalized in terms of strong binding of these cations to the N=C-NR2 functionality. The same effect has been observed for protonation. Depending on the size and the structure of the macrocyclic ring the complexation of cations by aza-crown ethers plays an important but secondary role. The interaction of Na+ and K+ with 2-aminopyridin-4-yl-DPPs leads to moderate enhancement of fluorescence due to the aza-crown ethers binding. The very weak fluorescence of DPP bearing 2-dialkylamino-pyridine-4-yl substituents is due to the closely lying T-2 state and the resulting intersystem crossing.

Copper- and DMF-mediated switchable oxidative C-H cyanation and formylation of imidazo[1,2-a]pyridines using ammonium iodide

The cyanation and formylation of imidazo[1,2-a]pyridines were developed under copper-mediated oxidative conditions using ammonium iodide and DMF as a nontoxic combined cyano-group source and DMF as a formylation reagent. Mechanistic studies indicate that the cyanation of imidazo[1,2-a]pyridines proceeds through a two-step sequence: initial iodination and then cyanation. The cyanation has a broad substrate scope and high functional group tolerance, and can be safely conducted on a gram scale. A novel copper-mediated formylation using the widely available DMF as the formylation reagent and environmentally friendly molecular oxygen as the oxidant has also been developed. This protocol also provided a convenient approach for the synthesis of clinically used saripidem.

Mapping Io’s Surface Composition With Juno/JIRAM

The surface composition of Io is dominated by SO2 frost, plus other chemical species identified or proposed over the past decades by combining Earth-based and space-based observations with laboratory data. Here we discuss spectroscopic data sets of Io obtained by the Jovian InfraRed Auroral Mapper (JIRAM) spectro-imager onboard Juno in nine orbits, spanning a 3-year period. We display average spectral profiles of Io in the 2-5 mu m range, and we use band depths derived from those profiles to map the geographic distribution of SO2 frost and other spectral features. This data set allows for an similar to 22% surface coverage at 58 to 162 km/px and in a broad range of latitudes. Our results confirm the broadly regional SO2-frost trends already highlighted by Galileo/NIMS. Io’s average spectral profiles as well as the mapping of the 4.47-mu m band also confirm that SO2 exists in the (SOO)-S-32-O-16-O-18 isotopic form. Surprisingly, the mapping performed by JIRAM shows that the absorption band at 2.1 mu m is unrelated to SO2 frost, while we map for the first time the depth of the 2.65-mu m band, highlighting regions enriched in this absorber, possibly H2S. JIRAM data confirm that the 3.92-mu m band, likely due to Cl2SO2, is largely related to the SO2 distribution. The correlation between Cl2SO2 and ClSO2, possibly revealed at 4.62 mu m, is not equally clear. The simultaneous presence of two very weak spectral features at 4.55 and 4.62 mu m suggests that nitrile compounds or tholins may also be present on the surface. Plain Language Summary The surface of Io is mainly covered by sulfur dioxide (SO2) frost and by other chemical species. The Jovian InfraRed Auroral Mapper (JIRAM) instrument onboard the NASA Juno spacecraft, in orbit around Jupiter, can occasionally observe the Galilean satellites through its slit spectrometer (2-5 mu m range). We show average spectral profiles of Io obtained by JIRAM in a 3-year period, mapping the geographic distribution of SO2 frost and other spectral features. Our results confirm the broadly regional SO2-frost trends already highlighted in the past. Our data confirm that SO2 exists in multiple isotopic forms. Surprisingly, the mapping performed by JIRAM shows that the absorption band at 2.1 mu m is unrelated to SO2 frost. We map for the first time the depth of the 2.65-mu m band, which might be related to hydrogen sulfide (H2S). We also highlight regions enriched in this absorber. We confirm that the 3.92-mu m band, ascribed to sulfuryl chloride (Cl2SO2), is largely correlated with the SO2 distribution. The correlation between Cl2SO2 and ClSO2, possibly revealed at 4.62 mu m, is not equally clear. The simultaneous presence of two very weak spectral features at 4.55 and 4.62 mu m suggests that nitrile compounds or tholins may also be present on the surface.

Rational Design of CYP3A4 Inhibitors: A One-Atom Linker Elongation in Ritonavir-Like Compounds Leads to a Marked Improvement in the Binding Strength

Inhibition of the major human drug-metabolizing cytochrome P450 3A4 (CYP3A4) by pharmaceuticals and other xenobiotics could lead to toxicity, drug-drug interactions and other adverse effects, as well as pharmacoenhancement. Despite serious clinical implications, the structural basis and attributes required for the potent inhibition of CYP3A4 remain to be established. We utilized a rational inhibitor design to investigate the structure-activity relationships in the analogues of ritonavir, the most potent CYP3A4 inhibitor in clinical use. This study elucidated the optimal length of the head-group spacer using eleven (series V) analogues with the R-1/R-2 side-groups as phenyls or R-1-phenyl/R-2-indole/naphthalene in various stereo configurations. Spectral, functional and structural characterization of the inhibitory complexes showed that a one-atom head-group linker elongation, from pyridyl-ethyl to pyridyl-propyl, was beneficial and markedly improved K-s, IC50 and thermostability of CYP3A4. In contrast, a two-atom linker extension led to a multi-fold decrease in the binding and inhibitory strength, possibly due to spatial and/or conformational constraints. The lead compound, 3h, was among the best inhibitors designed so far and overall, the strongest binder (K-s and IC50 of 0.007 and 0.090 mu M, respectively). 3h was the fourth structurally simpler inhibitor superior to ritonavir, which further demonstrates the power of our approach.

Femtosecond Charge Transfer Dynamics in Monomolecular Films in the Context of Molecular Electronics

A key issue of molecular electronics (ME) is the correlation between the molecular structure and the charge transport properties of the molecular framework. Accordingly, a variety of model and potentially useful molecular systems are designed, to prove a particular function or correlation or to build a prototype device. These studies usually involve the measurements of the static electric conductance properties of individual molecules and their assembles on solid supports. At the same time, information about the dynamics of the charge transport (CT) and transfer in such systems, complementary in the context of ME and of a scientific value on its own, is quite scarce. Among other means, this drawback can be resolved by resonant Auger electron spectroscopy (RAES) in combination with core hole clock (CHC) approach, as described in this Account. The RAES-CHC scheme was applied to a variety of aliphatic and aromatic self-assembled monolayers (SAMs), adsorbed on Au(111) over the thiolate and selenolate docking groups. Electron transfer (ET) from a suitable terminal tail group to the substrate, across the molecular framework, was monitored, triggered by resonant excitation of this group (nitrile in most cases) by narrow-band X-ray radiation. This resulted in the quantitative data for the characteristic ET time, tau(ET), in the femtosecond domain, with the time window ranging from similar to 1 fs to similar to 120 fs. The derived tau(ET) exhibit an exponential dependence on the molecular length, mimicking the behavior of the static conductance and suggesting a common physical basis behind the static CT and ET dynamics. The dynamic decay factors, beta(ET), for the alkyl, oligophenyl, and acene molecular wires correlate well with the analogous parameters for the static CT. Both tau(ET) and beta(ET) values exhibit a distinct dependence on the character of the involved molecular orbital (MO), demonstrating that the efficiency and rate of the CT in molecular assemblies can be controlled by resonant injection of the charge carriers into specific MOs. This dependence as well as a lack of correlation between the molecular tilt and tau(ET) represent strong arguments in favor of the generally accepted model of CT across the molecular framework (through-bond) in contrast to through-space tunneling. Comparison of the SAMs with thiolate and selenolate docking groups suggests that the use of selenolate instead of thiolate does not give any gain in terms of ET dynamics or molecular conductance. Whereas a certain difference in the efficiency of the electronic coupling of thiolate and selenolate to the substrate cannot be completely excluded, this difference is certainly too small to affect the performance of the entire molecule to a noticeable extent. The efficient electronic coupling of the thiolate docking group to the substrate was verified and the decoupling of the electronic subsystems of the substrate and pi-conjugated segment by introduction of methylene group into the backbone was demonstrated. No correlation between the molecular dipole or fluorine substitution pattern (at the side positions) and the ET efficiency was recorded. Several representative examples for the resonantly addressable tail groups are given, and perspectives for future research in the context of ET dynamics in molecular assemblies are discussed.

Electron Donor-Acceptor Complex-Initiated Photochemical Cyanation for the Preparation of alpha-Amino Nitriles

An electron donor-acceptor complex-initiated alpha-cyanation of tertiary amines has been described. The reaction protocol provides a novel method to synthesize various alpha-amino nitriles under mild conditions. The reaction can proceed smoothly without the presence of photocatalysts and transition metal catalysts, and either oxidants are unnecessary or O-2 is the only oxidant. The practicality of this method is showcased not only by the late-stage functionalization of natural alkaloid derivatives and pharmaceutical intermediate, but also by the applicability of a stop-flow microtubing reactor.

Direct Catalytic Asymmetric Addition of Alkylnitriles to Aldehydes with Designed Nickel-Carbene Complexes

A direct catalytic asymmetric addition of acetonitrile to aldehydes that realizes over 90 % ee is the ultimate challenge in alkylnitrile addition chemistry. Herein, we report achieving high enantioselectivity by the strategic use of a sterically demanding Ni-II pincer carbene complex, which afforded highly enantioenriched beta-hydroxynitriles. This highly atom-economical process paves the way for exploiting inexpensive acetonitrile as a promising C2 building block in a practical synthetic toolbox for asymmetric catalysis.
