Diastereoselective Acylation of Racemic Heterocyclic Amines with N-Phthaloyl and N-Naphthaloyl (S)-Amino Acyl Chlorides: Possibility of Parallel Kinetic Resolution

The acylative kinetic resolution of racemic 2-methyl-1,2,3,4-tetrahydroquinoline and 3,4-dihydro-3-methyl-2H-[1,4]benzoxazines with acyl chlorides of N-naphthaloyl-(S)-alanine and N-naphthaloyl-(S)-phenylalanine has been studied. It has been shown that diastereoselective acylation of racemic amines with N-naphthaloyl (S)-amino acyl chlorides results in the predominant formation of (R,S)-amides, whereas acylation of the same amines with N-phthaloyl (S)-amino acyl chlorides proceeds with the opposite diastereoselectivity. The parallel kinetic resolution of racemic 3,4-dihydro-3-methyl-2H-[1,4]benzoxazine using a mixture of acylating agents derived from a single precursor, (S)-phenylalanine, was carried out.

Engineered (Lys)(6)-Tagged Recombinant Sulfide-Reactive Hemoglobin I for Covalent Immobilization at Multiwalled Carbon Nanotubes

The recombinant HbI was fused with a poly-Lys tag ((Lys)(6)-tagged rHbI) for specific-site covalent immobilization on two carbon nanotube transducer surfaces, i.e., powder and vertically aligned carbon nanotubes. The immobilization was achieved by following two steps: (1) generation of amine-reactive ester from the carboxylic acid groups of the surfaces and (2) coupling these groups with the amine groups of the Lys-tag. We analyzed the immobilization process using different conditions and techniques to differentiate protein covalent attachment from physical adsorption. Fourier transform infrared microspectroscopy data showed a 14 cm(-1) displacement of the protein’s amide I and amide II peaks to lower the frequency after immobilization. This result indicates a covalent attachment of the protein to the surface. Differences in the morphology of the carbon substrate with and without (Lys)(6)-tagged rHbI confirmed protein immobilization, as observed by transmission electron microscopy. The electrochemical studies, which were performed to evaluate the redox center of the immobilized protein, show a confinement suitable for an efficient electron transfer system. More importantly, the electrochemical studies allowed determination of a redox potential for the new (Lys)(6)-tagged rHbI. The data show that the protein is electrochemically active and retains its biological activity toward H2S.

Activated potassium ions as CO2 carriers for PEBAX-5513/KBF4 composite membranes

This study showed that potassium tetrafluoroborate (KBF4) could be used as a carrier to facilitate the transport of CO2. A polymer electrolyte membrane was prepared by incorporating KBF4 into poly (ether-block-amide) (PEBAX-5513) with a flexible PE group. The prepared PEBAX-5513/KBF4 electrolyte membrane exhibited CO2 separation performance that was improved by nine times compared to pure PEBAX-5513 and by about seven times compared to a PVP/KF electrolyte membrane. The membrane exhibited a selectivity of 27.9. This improved separation performance increased the transport of CO2 owing to the reversible interaction of the dissociated potassium ions with CO2 molecules. The dissociation of potassium ions upon thermal treatment of the material was confirmed by Fourier transform Raman spectroscopy, and the selective layer in which the separation mechanism was generated was confirmed by scanning electron microscopy.

Positron Emission Tomography Imaging of the Endocannabinoid System: Opportunities and Challenges in Radiotracer Development

The endocannabinoid system (ECS) is involved in a wide range of biological functions and comprises cannabinoid receptors and enzymes responsible for endocannabinoid synthesis and degradation. Over the past 2 decades, significant advances toward developing drugs and positron emission tomography (PET) tracers targeting different components of the ECS have been made. Herein, we summarized the recent development of PET tracers for imaging cannabinoid receptors 1 (CB1R) and 2 (CB2R) as well as the key enzymes monoacylglycerol lipase (MAGL) and fatty acid amide hydrolase (FAAH), particularly focusing on PET neuroimaging applications. State-of-the-art PET tracers for the ECS will be reviewed including their chemical design, pharmacological properties, radiolabeling, as well as preclinical and human PET imaging. In addition, this review addresses the current challenges for ECS PET biomarker development and highlights the important role of PET ligands to study disease pathophysiology as well as to facilitate drug discovery.

Encapsulation of Sardine Oil by Electrospraying with Gliadins and Pecan Nutshell Extracts for its Stabilization

This study is the first to report the optimization of diameter of encapsulated sardine oil (SO) particles with gliadins and pecan nutshell extract as wall material during electrospraying. Firstly, the physicochemical stabilization of the encapsulated SO with or without nutshell extract was investigated and compared with the nonencapsulated SO. The average diameter of the SO particles with or without nutshell extracts was around 1473 nm and 564-999 nm, respectively. The two types of encapsulation showed higher encapsulation efficiency (94 and 98%) and loading capacity (25 and 26%). Results from the Rancimat test demonstrated that nutshell extracts at 0.030 and 0.050% w/w improved the oxidative stability of the nonencapsulated SO and improved the stability of the encapsulated SO even more (up to 48 h). FTIR results showed a modification in the secondary structure of the gliadins at the amide I band, indicating the interaction between SO and gliadin and explaining the increase in the oxidative stability of encapsulated SO. In summary, these results indicate that gliadins and pecan nutshell extract could be used as new wall materials for encapsulation and stabilization of SO. Also, pecan nutshell extract could be used as a nutraceutical ingredient or to develop of functional foods by the food industry.

Gut satiety hormones cholecystokinin and glucagon-like Peptide-1(7-36) amide mediate anorexia induction by trichothecenes T-2 toxin, HT-2 toxin, diacetoxyscirpenol and neosolaniol

The food-borne trichothecene mycotoxins have been documented to cause human and animal food poisoning. Anorexia is a hallmark of the trichothecene mycotoxins-induced adverse effects. Type B trichothecenes have been previously demonstrated to elicit robust anorectic responses, and this response has been directly linked to secretion of the gut satiety hormones cholecystokinin (CCK) and glucagon-like peptide-1(7-36) amide (GLP-1). However, less is known about the anorectic effects and underlying mechanisms of the type A trichothecenes, including T-2 toxin (T-2), HT-2 toxin (HT-2), diacetoxyscirpenol (DAS), neosolaniol (NEO). The purpose of this study was to relate type A trichothecenes T-2, HT-2, DAS and NEO-induced anorectic response to changes plasma concentrations of CCK and GLP-1. Following both oral gavage and intraperitoneal (IP) administration of 1 mg/kg bw T-2, HT-2, DAS and NEO evoked robust anorectic response and secretion of CCK and GLP-1. Elevations of plasma CCK markedly corresponded to anorexia induction by T-2, HT-2, DAS and NEO. Following oral exposure, plasma CCK was peaked at 6 h, 6 h, 2 h, 2 h and lasted up to 24 h, 24 h, > 6 h, > 6 h for T-2, HT-2, DAS and NEO, respectively. IP exposed to four toxins all induced elevation of CCK with peak point and duration at 6 h and > 24 h, respectively. In contrast to CCK, GLP-1 was moderately elevated by these toxins. Following both oral and IP exposure, T-2 and HT-2 evoked plasma GLP-1 elevation with peak point and duration at 2 h and 6 h, respectively. Plasma GLP-1 was peaked at 2 h and still increased at 6 h for IP and oral administration with DAS and NEO, respectively. In conclusion, CCK plays a contributory role in anorexia induction but GLP-1 might play a lesser role in this response.

Improved spinnability of PA 6 solutions using AC electrospinning

The experiment addressed the alternating current (AC) electrospinning of polyamide 6 (PA 6) solutions composed of organic acids, which are commonly employed in direct current (DC) electrospinning systems. Initial testing revealed that it is not possible to AC spin ordinary PA 6 solutions so as to provide a product that can be used in subsequent material experiments. The solutions were enriched with oxoacids, which led to the improvement of the spinning process. The solutions were tested by means of both a viscometer and conductivity meter. The layers so produced were scanned using a SEM microscope. Each of the materials was analyzed for the purpose of the provision of statistical data. (C) 2020 Elsevier B.V. All rights reserved.

Relevance of Peroxisome Proliferator Activated Receptors in Multitarget Paradigm Associated with the Endocannabinoid System

Cannabinoids have shown to exert their therapeutic actions through a variety of targets. These include not only the canonical cannabinoid receptors CB1R and CB2R but also related orphan G protein-coupled receptors (GPCRs), ligand-gated ion channels, transient receptor potential (TRP) channels, metabolic enzymes, and nuclear receptors. In this review, we aim to summarize reported compounds exhibiting their therapeutic effects upon the modulation of CB1R and/or CB2R and the nuclear peroxisome proliferator-activated receptors (PPARs). Concomitant actions at CBRs and PPAR alpha or PPAR gamma subtypes have shown to mediate antiobesity, analgesic, antitumoral, or neuroprotective properties of a variety of phytogenic, endogenous, and synthetic cannabinoids. The relevance of this multitargeting mechanism of action has been analyzed in the context of diverse pathologies. Synergistic effects triggered by combinatorial treatment with ligands that modulate the aforementioned targets have also been considered. This literature overview provides structural and pharmacological insights for the further development of dual cannabinoids for specific disorders.

Ruthenium(IV) Intermediates in C-H Activation/Annulation by Weak O-Coordination

Ruthenium(IV) complexes were identified as key intermediates of C-H/O-H activations by weak O-coordination. Thus, the annulations of sulfoxonium ylides by benzoic acids provided expedient access to diversely-decorated isocoumarins with ample scope. Detailed experimental and computational studies provided strong support for a facile BIES-C-H activation, along with cyclometalated ruthenium(IV) intermediates within a versatile ruthenium(II/IV) catalysis regime (BIES=base-assisted internal electrophilic substitution).
