The syntheses of zinc(II) tetra-[3-(4-phenoxy) (propanoic acid) phthalocyanine] (2) and zinc(II) mono[3-(4-phenoxy) (propanoic acid) phthalocyanine (3) are reported in this work. Compounds 2 and 3 were covalently linked to glutathione capped silver (AgNPs-GSH), gold (AuNPs-GSH) and silver-gold alloy (Ag(3)Au(1)NPs-GSH) nanoparticles (NPs) via an amide bond formation to afford the conjugates: 2-AgNPs-GSH, 3-AgNPs-GSH, 2-AuNPs-GSH, 3-AuNPs-GSH, 2-Ag(3)Au(1)NPs-GSH and 3-Ag(3)Au(1)NPs-GSH. The photophysicochemical behaviours of the compounds and their conjugates with NPs were assessed in solution. The conjugates afforded a decrease in fluorescence quantum yields and lifetimes with improved triplet quantum yields in comparison to the compounds. Accordingly, the AgNPs and AuNPs conjugates with the compounds afforded high singlet quantum yields. On the contrary, the conjugates of the alloy afforded decreased singlet quantum yields probably due to the screening effect. The compounds and their conjugates with NPs could serve as a viable and efficacious photosensitizer for photodynamic therapy. (C) 2017 Elsevier B.V. All rights reserved.

Selective extraction of highly radiotoxic actinides(III) is an important and challenging task in nuclear wastewater treatment. Many proposed ligands containing S or P atoms have drawbacks including high reagent consumption and possible secondary pollution after incineration. The present work reports five novel pillar[5]arene-based extractants that are anchored with picolinamide substituents of different electronic nature by varying spacer. These ligands reveal highly efficient separation of actinides(III) over lanthanides(III). Specifically, almost all of these ligands could extract Am(III) over Eu(III) selectively at around pH 3.0 (SFAm/Eu > 11) with fast extraction kinetics. Variation of the pyridine nitrogen basicity via changing para-substitution leads to an increase in the distribution ratios by a factor of over 300 times for Am(III) with an electron-withdrawing group compared to those with an electron donating group. Investigation of complexation mechanism by slope analysis, NMR, IR, EXAFS, and DFT techniques indicates that each ligand binds two metal ions by pyridine nitrogen and amide oxygen. Finally, these ligands do not show obvious decrease in both extraction and separation ability after being exposed to 250 kGy absorbed gamma radiation. These results demonstrate the potential application of pillar[5] arene-picolinamides for actinide(III) separation.

Analgesic effects of FAAH inhibitor in the insular cortex of nerve-injured rats

The insular cortex is an important region of brain involved in the processing of pain and emotion. Recent studies indicate that lesions in the insular cortex induce pain asymbolia and reverse neuropathic pain. Endogenous cannabinoids (endocannabinoids), which have been shown to attenuate pain, are simultaneously degraded by fatty acid amide hydrolase (FAAH) that halts the mechanisms of action. Selective inhibitor URB597 suppresses FAAH activity by conserving endocannabinoids, which reduces pain. The present study examined the analgesic effects of URB597 treatment in the insular cortex of an animal model of neuropathic pain. Under pentobarbital anesthesia, male Sprague-Dawley rats were subjected to nerve injury and cannula implantation. On postoperative day 14, rodents received microinjection of URB597 into the insular cortex. In order to verify the analgesic mechanisms of URB597, cannabinoid 1 receptor (CB1R) antagonist AM251, peroxisome proliferator-activated receptor alpha (PPAR alpha) antagonist GW6471, and transient receptor potential vanilloid 1 (TRPV1) antagonist Iodoresiniferatoxin (I-RTX) were microinjected 15 min prior to URB597 injection. Changes in mechanical allodynia were measured using the von-Frey test. Expressions of CB1R, N-acyl phosphatidylethanolamine phospholipase D (NAPE-PLD), and TRPV1 significantly increased in the neuropathic pain group compared to the sham-operated control group. Mechanical threshold and expression of NAPE-PLD significantly increased in groups treated with 2 nM and 4 nM URB597 compared with the vehicle-injected group. Blockages of CB1R and PPAR alpha diminished the analgesic effects of URB597. Inhibition of TRPV1 did not effectively reduce the effects of URB597 but attenuated expression of NAPE-PLD compared with the URB597-injected group. In addition, optical imaging demonstrated that neuronal activity of the insular cortex was reduced following URB597 treatment. Our results suggest that microinjection of FAAH inhibitor into the insular cortex causes analgesic effects by decreasing neural excitability and increasing signals related to the endogenous cannabinoid pathway in the insular cortex.

An Ionic Liquid-based Microextraction Method for Ultra-High Preconcentration of Paraquat Traces in Water Samples Prior to HPLC Determination

An ionic liquid (IL)-based microextraction method was developed for the preconcentration of paraquat traces in water samples prior to HPLC determination. On the basis of the relationship between the aqueous solubility and the extractability of known ILs, l-ethyl-3-methylimidazolium bis(nonafluorobutanesulfonyl)amide ([EMIm][NNf(2)]) was selected as the extractant for paraquat. The distribution ratio of paraquat dication in the [EMIm][NNf(2)]/water biphasic system was theoretically estimated to be nearly 10(8) at its maximum level, indicating that [EM1m][NNf(2)] was suitable for the ultra-high preconcentration (a maximum of 10(6)-fold concentration) of paraquat with a quantitative recovery (more than 99%). The extraction procedure could be performed easily and quickly following the in situ solvent formation microextraction technique, and the paraquat traces in the IL phase could be determined by hydrophilic interaction chromatography with good detection limits and linearity ranges (0.16 and 1 – 50 ng mL(-1) for paraquat, respectively). The combined method was successfully applied to four real environmental water samples spiked with paraquat and its analog, diquat at 5.0 ng mL(-1).

Aldehyde Decarbonylation by a Cobalt(I) Pincer Complex

The cobalt(I) pincer complex, [Co(N-2)-((PNP)-P-cy)] ((cy)pNP = anion of 2,5-bis-((dicyclohexylphosphino)methyl)pyrrole), reacts with aromatic, vinylic, and aliphatic aldehydes to produce the corresponding hydrocarbon products and [Co(CO)-((PNP)-P-cy)]. The pathway for aldehyde decarbonylation is found to involve initial coordination of the aldehyde to Co(I), followed by oxidative addition of the C-H bond to produce a cobalt(III) acyl hydride. The acyl hydride species then undergoes CO deinsertion, followed by reductive elimination to afford the decarbonylated product and [Co(CO)((PNP)-P-cy)]. Reactions of [Co(N-2)((PNP)-P-cy)] with other carbonyl containing groups such as carboxylic acids and amides also proceed via oxidative addition to give Co(III) intermediates arising from activation of the X-H (X = 0 or NH) bond. In these cases, however, the Co(III) species extrude molecular hydrogen to produce Co(II) species of the form [Co(X{O}CR)((PNP)-P-cy)] (X = O or NH). The ability of [Co(N-2)((PNP)-P-cy)] to undergo facile oxidative addition is discussed in the context of potential bond activation processes mediated by well-defined Co species.

Electrochemical Cobalt-Catalyzed C-H Activation

Carbon-heteroatom bonds represent omnipresent structural motifs of the vast majority of functionalized materials and bioactive compounds. C-H activation has emerged as arguably the most efficient strategy to construct C-Het bonds. Despite of major advances, these C-H transformations were largely dominated by precious transition metal catalysts, in combination with stoichiometric, toxic metal oxidants. Herein, we discuss the recent evolution of cobalt-catalyzed C-H activations that enable C-Het formations with electricity as the sole sustainable oxidant until May 2018.

Effects of High Hydrostatic Pressure assisted degreasing on the technological properties of insect powders obtained from Acheta domesticus & Tenebrio molitor

In this study, two edible insect species; Acheta domesticus (house cricket) and Tenebrio molitor (yellow mealworm) were defatted using different extraction methods and characterized afterwards. The main goal of the study was to see the effect of High Hydrostatic Pressure (HHP) extraction at different temperatures on the functional properties of the insect powders. Protein content, solubility, water and oil binding capacity; total phenolic content and antioxidant activity were all effected from the extraction method. Results showed that, temperature increase from 30 to 40 degrees C caused a decrease in the protein solubility of both powders. NMR relaxometry was used to interpret the gelation behavior and FTIR spectroscopy showed absorbance peaks mainly in amide I, amide II and amide III regions for both species. Results confirmed that HHP can be used for defatting purposes and could improve the functional properties of the powders to be used as a food additive in formulations.

Synthesis of Tetra-Substituted Trifluoromethyl-3,1-Benzoxazines by Transition-Metal-Catalyzed Decarboxylative Cyclization of N-Benzoyl Benzoxazinones

Efficient synthesis of N,O-heterocyclic tetra-substituted trifluoromethyl-3,1-benzoxazines via a transition-metal-catalyzed decarboxylative intramolecular cyclization was achieved. The decarboxylation of N-benzoyl trifluoromethyl-benzoxazinones generated the amide oxygen nucleophile, allowing a selective internal C-1-attack on Pd- or Cu-coordinated zwitterions, affording medicinally attractive tetra-substituted vinyl- or ethynyl-trifluoromethyl-3,1-benzoxazines. This protocol can be applied to the synthesis of perfluoroalkyl- and non-fluorinated 3,1-benzoxazines.

Intermolecular interactions in the crystal structures of chlorogold(I) complexes with N-phosphinoamide ligands

[AuCl{RC(O)NHPPh2-kappa P}]gold(I) complexes with varying amide substituents (R = Me, Ph and ferrocenyl) were prepared, characterized by elemental analysis and spectroscopic methods (mass spectrometry and multinuclear NMR and IR spectroscopy) and further studied by single-crystal X-ray crystallography with a particular focus on solid-state interactions. In all cases, the crystal assembly was based mainly on conventional hydrogen bonds between the amide moieties. However, while in chloroform-solvated [AuCl{MeC(O)NHPPh2-kappa P}], these interactions were supported by pi center dot center dot center dot pi stacking of aromatic rings, in the crystal structures of the complexes bearing phenyl and ferrocenyl substituents, they cooperated with aurophilic interactions of the Au(I) centers, which in turn affected the C = O center dot center dot center dot HN hydrogen bonds.
