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.

Structure-Based Design of Melanocortin 4 Receptor Ligands Based on the SHU-9119-hMC4R Cocrystal Structure

The melanocortin receptors (MC1R-MC5R) belong to class A G-protein-coupled receptors (GPCRs) and are known to have receptor-specific roles in normal and diseased states. Selectivity for MC4R is of particular interest due to its involvement in various metabolic disorders, including obesity, feeding regulation, and sexual dysfunctions. To further improve the potency and selectivity of MC4R (ant)agonist peptide ligands, we designed and synthesized a series of cyclic peptides based on the recent crystal structure of MC4R in complex with the well-characterized antagonist SHU-9119 (Ac-Nle(4)-c [Asp(5)-His(6)-DNal (2′ )(7)-Arg(8)-Trp(9)- Lys(10)]-NH2). These analogues were pharmacologically characterized in vitro, giving key insights into exploiting binding site subpockets to deliver more selective ligands. More specifically, the side chains of the Nle(4), DNal(2′)(7), and Trp(9) residues in SHU-9119, as well as the amide linkage between the Asp(5) and Lys(10) side chains, were found to represent structural features engaging a hMC4R/hMC3R selectivity switch.

Raman spectral discrimination in human liquid biopsies of oesophageal transformation to adenocarcinoma

The aim of this study was to determine whether Raman spectroscopy combined with chemometric analysis can be applied to interrogate biofluids (plasma, serum, saliva and urine) towards detecting oesophageal stages through to oesophageal adenocarcinoma [normal/squamous epithelium, inflammatory, Barrett’s, low-grade dysplasia, high-grade dysplasia and oesophageal adenocarcinoma (OAC)]. The chemometric analysis of the spectral data was performed using principal component analysis, successive projections algorithm or genetic algorithm (GA) followed by quadratic discriminant analysis (QDA). The genetic algorithm quadratic discriminant analysis (GA-QDA) model using a few selected wavenumbers for saliva and urine samples achieved 100% classification for all classes. For plasma and serum, the GA-QDA model achieved excellent accuracy in all oesophageal stages (>90%). The main GA-QDA features responsible for sample discrimination were: 1012 cm(-1) (CO stretching of ribose), 1336 cm(-1) (Amide III and CH2 wagging vibrations from glycine backbone), 1450 cm(-1) (methylene deformation) and 1660 cm(-1) (Amide I). The results of this study are promising and support the concept that Raman on biofluids may become a useful and objective diagnostic tool to identify oesophageal disease stages from squamous epithelium to OAC.

Highly chemoselective and efficient production of 2,6-difluorobenzamide using Rhodococcus ruber CGMCC3090 resting cells

Chemoselective biocatalytic hydrolysis of nitriles is a valuable alternative to chemical hydrolysis that operates under harsh conditions. 2,6-Difluorobenzamide (DFBAM) is an essential intermediate derived from synthesis of benzoyl urea insecticide from 2,6-difluorobenzonitrile (DFBN). High yield of DFBAM was achieved, and the method using resting cells of Rhodococcus ruber CGMCC3090 exhibited excellent product specificity. The reaction parameters for DFBAM biosynthesis were also investigated. The resting cells effectively converted DFBN at high concentrations of up to 3.5 mol L-1 without forming acids or other by-products. Therefore, biological production of DFBAM features high yield, chemoselectivity, low cost, and environment friendliness and is more suitable to the industry than chemical synthesis techniques.

Green synthesis, in vivo and in vitro pharmacological studies of Tamarindus indica based gold nanoparticles

The current investigation aims to synthesize gold nanoparticles (AuNPs) from aqueous extract of Tamarindus indica and to evaluate the in vitro anti-bacterial and in vivo sedative and anelgescic activities of crude extract as well as synthesized AuNPs. Several methods have been reported to synthesize AuNPs; however, most of them were not ecofriendly. In the present study, the green synthesis of AuNPs has been carried out. Using the green synthesis method, AuNPs of T. indica were synthesized at room temperature (25 degrees C) by mixing 5 mL of HAuCl4 (1 mM) with 1 mL of T. indica seed extract solution. This extract solution was prepared by taking 5 gm dry seeds in 100 mL of double deionized water with continuous stirring for up to 24 h at 80 degrees C. The stability of AuNPs was confirmed with the help of relevant experimental techniques including ultraviolet-visible (UV/Vis) showing maximum absorbance at 535-540 nm, Fourier transform infrared showing a broad signal at 3464 cm(-1) which can be attributed to either amide or hydroxyl functionalities and atomic force microscopy analysis showed that the biomaterial surrounding AuNPs was agglomerated which proves the formation of discrete nanostructutres. These AuNPs have been evaluated for their antibacterial potential. The results revealed good antibacterial activity of the samples against. Klebsiella pneumonia, Bacillus subtilis and Staphylococcus epidermidis with 10-12 mm zone of inhibition range. The AuNPs were also found stable at high temperature, over a range of pH and in 1 mM salt solution. Moreover, the crude extract and respective AuNPs also exhibited interesting sedative and analgesic activities. Hence, we focused on phytochemicals-mediated synthesis of AuNPs considered as greatest attention in the treatment of anti-bacterial, analgesic, and sedative.

Preparation of Functionalized Diaryl-and Diheteroaryllanthanum Reagents by Fast Halogen-Lanthanum Exchange

Aryl and heteroaryl halides (X= Br, I) undergo a fast and convenient halogen-lanthanum exchange with nBu(2)LaMe, which leads to functionalized diaryl-and dihetero-aryllanthanum derivatives. Subsequent trapping reactions with selected electrophiles, such as ketones, aldehydes, or amides, proceeded smoothly at -508 degrees C in THF, affording polyfunctionalized alcohols and carbonyl derivatives. Kinetic competition experiments revealed a similar reactivity trend as for Br/Mg exchange, but 106-times higher rates, making it comparable to Br/Li exchange.
