Elucidating the pyrolysis reaction mechanism of Calotropis procera and analysis of pyrolysis products to evaluate its potential for bioenergy and chemicals

The present study was focused on evaluating the bioenergy potential of waste biomass of desert plant Calotropis procera. The biomass was pyrolyzed at four heating rates including 10 degrees Cmin(-1), 20 degrees Cmin(-1), 40 degrees Cmin(-1), and 80 degrees Cmin(-1). The pyrolysis reaction kinetics and thermodynamics parameters were assessed using isoconversional models namely Kissenger-Akahira-Sunose, Flynn-Wall-Ozawa, and Starink. Major pyrolysis reaction occurred between 200 and 450 degrees C at the conversion points (alpha) ranging from 0.2 to 0.6 while their corresponding reaction parameters including activation energy, enthalpy change, Gibb’s free energy and pre-exponential factors were ranged from 165 to 207 kJ mol(-1), 169-200 kJ mol(-1), 90-42 kJ mol(-1), and 10(18)-10(26) s(-1), respectively. The narrow range of pre-exponential factors indicated a uniform pyrolysis, while lower differences between enthalpy change and activation energies indicated that reactions were thermodynamically favorable. The evolved gases were dominated by propanoic acid, 3-hydroxy-, hydrazide, hydrazinecarboxamide and carbohydrazide followed by amines/amides, alcohols, acids, aldehydes/ketones, and esters.

A dual inhibitor of FAAH and TRPV1 channels shows dose-dependent effect on depression-like behaviour in rats

Objective The cannabinoid receptor 1 (CB1) and transient receptor potential cation channel subfamily V member 1 (TRPV1) are proposed to mediate opposite behavioural responses. Their common denominator is the endocannabinoid ligand anandamide (AEA), which is believed to mediate antidepressant-like effect via CB1-R stimulation and depressive-like effect via TRPV1 activation. This is supposed to explain the bell-shaped dose-response curve for anandamide in preclinical models. Methods We investigated this assumption by administering the dual inhibitor of AEA hydrolysis and TRPV1 activation N-arachidonoyl-serotonin (AA-5HT) into the medial prefrontal cortex of rats. AA-5HT was given in three different doses (0.125, 0.250, 0.500 nmol/0.4 mu l/side) and rat behaviour was assessed in the forced swim test. Results Our results show significant antidepressant-like effect of AA-5HT (0.250 nmol) but no effects of low or high doses. The effect of 0.250 nmol AA-5HT was partially attenuated when coadministering the inverse CB1-agonist rimonabant (1.6 mu g). Conclusion A 0.250 nmol of AA-5HT administration into the medial prefrontal cortex induced a significant antidepressant-like effect that was partially attenuated by locally blocking CB1-receptor.

Combining H/D Exchange Mass Spectrometry and Computational Docking To Derive the Structure of Protein-Protein Complexes

Protein protein interactions are essential for biological function, but structures of protein protein complexes are difficult to obtain experimentally. To derive the protein complex of the DNA-repair enzyme human uracil-DNA-glycosylase (hUNG) with its protein inhibitor (UGI), we combined rigid-body computational docking with hydrogen/deuterium exchange mass spectrometry (DXMS). Computational docking of the unbound protein structures provides a list of possible three-dimensional models of the complex; DXMS identifies solvent-protected protein residues. DXMS showed that unbound hUNG is compactly folded, but unbound UGI is loosely packed. An increased level of solvent protection of hUNG in the complex was localized to four regions on the same face. The decrease in the number of incorporated deuterons was quantitatively interpreted as the minimum number of main-chain hUNG amides buried in the protein protein interface. The level of deuteration of complexed UGI decreased throughout the protein chain, indicating both tighter packing and direct solvent protection by hUNG. Three UGI regions showing the greatest decreases were best interpreted leniently, requiring just one main-chain amide from each in the interface. Applying the DXMS constraints as filters to a list of docked complexes gave the correct complex as the largest favorable energy cluster. Thus, identification of approximate protein interfaces was sufficient to distinguish the protein complex. Surprisingly, incorporating the DXMS data as added favorable potentials in the docking calculation was less effective in finding the correct complex. The filtering method has greater flexibility, with the capability to test each constraint and enforce simultaneous contact by multiple regions, but with the caveat that the list from the unbiased docking must include correct complexes.

Preparation and Structure of Protonated Selenourea

Selenourea was investigated in the binary superacidic media XF/MF5 (X = H, D; M = As, Sb). The protonation selectively takes place at the selenium atom leading to the corresponding salts [(X2N)(2)CSeX](+)[MF6](-). The characterization of the colorless salts was performed by low temperature vibrational spectroscopy. In the case of [(H2N)(2)CSeH](+)[SbF6](-) a single-crystal X-ray structure analysis is reported. The observed Se center dot center dot center dot F interaction in the solid state is discussed in context of sigma-hole interactions. Selenourea undergoes structural changes due to the protonation which are discussed together with quantum-chemical calculations.

Coordination and catalytic chemistry of phosphinoferrocene carboxamides

Amidation reactions of ferrocene phosphinocarboxylic acids and various simple or functional amines provide access to a range of specific metalloligands combining the soft phosphine moiety with easily changeable, hard-donor amide substituents. Compounds of this type are also accessible in a complementary manner, as demonstrated by the reactions of [1′-(diphenylphosphino)ferrocenyl]methylamine with carboxylic acids (or their derivatives) and isocyanates. Owing to their hybrid nature, phosphinoferrocene carboxamides are versatile ligands for coordination chemistry and catalysis. Applications in such areas particularly benefit from the modular structures of these compounds, which allow the design and synthesis of extensive ligand libraries and, hence, the fine tuning of their properties for a particular use. Moreover, phosphinoferrocene amides can easily be made chiral using either a chiral ferrocene precursor or an attached chiral pendant. The amide linking group stabilizes the phosphinoferrocene moiety towards oxidation and endows phosphinoferrocene amides with the ability to participate in hydrogen bonding interactions and, consequently, form well-defined supramolecular assemblies in the solid state. As a defined linker, the amide moiety can be used to attach phosphinoferrocene moieties onto a larger scaffold (e.g., dendrimers) and thus create multidonor arrays. Furthermore, the presence of the amide moiety renders the phosphinoferrocene carboxamides useful synthetic building blocks. (C) 2017 Elsevier B.V. All rights reserved.

Mass spectral and theoretical investigations of the transient proton-bound dimers on the cleavage processes of the peptide GHK and its analogues

Fragmentation mechanisms of the singly protonated peptides GHK, GHKH and HGHK have been investigated by mass spectrometry and theoretical calculations. Fragmentation behavior of the protonated H-K amide bond in GHK was changed completely when a histidinyl residue was introduced into the C-terminus of GHK. The H-K amide bond breaking was a predominant pathway in the case of GHK and GHKH. For HGHK, the histidinyl residue at the N-terminus hampered significantly breaking of the H-K amide bond resulting in a high potential energy barrier; calculations indicated that this histidinyl effect played a vital role for the H-K amide bond fragmentation. Subsequent analysis of the fragmentation mechanism revealed that recombination processes of the hydrogen bonding for the intermediate products were all exergonic. Formation of a proton-bound dimer (PBD) lowering the energy barriers from a thermodynamic perspective for all the designed fragmentation pathways was demonstrated to be feasible by our systematic calculations. Moreover, the involvement of different PBDs was further confirmed by analyses of the reduced density gradient (RDG) isosurfaces and scatter maps. A dynamically favored pathway was likely via six-membered ring or nine-membered ring structures generated by the diketopiperazine as revealed by atom-in-molecules (AIM) analyses, since the steric interaction energies in the newly formed ring were estimated to be relatively small when compared to the products generated from a lactam and/or an oxazolone pathway. This is the first feasibility investigation from a dynamic viewpoint for formation of different rings involved in the lactam, oxazolone or diketopiperazine pathways in the fragmentation mechanisms proposed.

Near-Infrared Fluorescent Probe with Remarkable Large Stokes Shift and Favorable Water Solubility for Real-Time Tracking Leucine Aminopeptidase in Living Cells and In Vivo

Leucine aminopeptidase (LAP) is a kind of proteolytic enzymes and associated closely with pathogenesis of cancer and liver injury. Accurate detection of LAP activity with high sensitivity and selectivity is imperative to detect its distribution and dynamic changes for understanding LAP’s function and early diagnosing the disease states. However, fluorescent detection of LAP in living systems is challenging. To date, rarely fluorescent probes have been reported for imaging LAP in vivo. In this study, a novel probe (TMN-Leu) was developed by conjugating a near-infrared dicyanoisophorone derivative fluorophore with LAP activatable L-leucine amide moiety for the first time. TMN-Leu featured large Stokes shift (198 nm), favorable water solubility, ultrasensitive sensitivity (detection limit of similar to 0.38 ng/mL), good specificity, excellent cell membrane permeability, low toxicity, and a prominent near-infrared emission (658 nm) in response to LAP. TMN-Leu has been successfully applied to track LAP of cancer cells and normal cells, monitor LAP changes in different disease models, and rapidly evaluate LAP inhibitor in cell-based assay. Notably, this probe firstly revealed that HCT116 cells with higher LAP activity were more invasive than LAP siRNA transfected HCT116 cells, suggesting that LAP might serve as an indicator reflecting the intrinsic invasion ability of cancer cells. Finally, TMN-Leu was also employed for in vivo real-time imaging LAP in living tumor-bearing nude mice with low background interference. All together, our probe possesses potential value as a promising tool for diagnostic application, cell-based screening inhibitors and in vivo real-time tracking enzymatic activity in preclinical applications.

Ring-Closing Olefin Metathesis Catalyzed by Well-Defined Vanadium Alkylidene Complexes

Vanadium-based catalysts have shown activity and selectivity in ring-opening metathesis polymerization of strained cyclic olefins comparable to those of Ru, Mo, and W catalysts. However, the application of V alkylidenes in routine organic synthesis is limited. Here, we present the first example of ring-closing olefin metathesis catalyzed by well-defined V chloride alkylidene phosphine complexes. The developed catalysts exhibit tolerance to various functional groups, such as an ether, an ester, a tertiary amide, a tertiary amine, and a sulfonamide. The size and electron-donating properties of the imido group and the phosphine play a crucial role in the stability of active intermediates. Reactions with ethylene and olefins suggest that both beta-hydride elimination of the metallacyclobutene and bimolecular decomposition are responsible for catalyst degradation.
