Columnar self-assembly, electrochemical and luminescence properties of basket-shaped liquid crystalline derivatives of Schiff-base-moulded p-tert-butyl-calix[4]arene

A new family of supramolecular liquid crystalline compounds with a calix[4]arene core and two linking groups appended on four sides, exhibiting a wide range of hexagonal columnar phases, has been synthesised and well characterised. The liquid crystal behaviour of the novel materials was studied by using polarising optical microscopy (POM), differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA), and was further confirmed using high-temperature powder X-ray diffraction (XRD). An electrochemical study was carried out using cyclic voltammetry (CV) and the results were compared with theoretical values obtained from a DFT study. These compounds showed light sky-blue luminescence in solution and as a thin film under long-wavelength UV light. It was observed that all the prepared target compounds exhibited enantiotropic mesophases with good thermal stability. The structural and conformational characterisation of these new compounds was achieved using various spectroscopic techniques, including FT-IR, H-1 NMR, C-13 NMR and MALDI-TOF. The relationship between the structure and the mesomorphic behaviour of the compounds containing an ethyl bridge with linked ester groups (5a-5d) is discussed. This new class of supramolecular derivatives is promising, especially considering the emissive nature and stabilisation of their columnar hexagonal mesophases, and their high range of thermal stability.

Synthesis of boronophenylalanine-like aza-amino acids for boron-containing azapeptide precursors

Aza-amino acids and an azapeptide with a boron-containing substituent were developed for the first time. We synthesized p-boronophenylalanine (BPA)-like aza-amino acid (aza-BPA) and its analogs in which the alpha-carbon of the peptide is replaced by nitrogen and the boronate ester is situated at the ortho, meta, or para position of the phenyl group. The N- and C-terminals of aza-BPA were linked to alpha-amino acids to afford an alpha/aza/alpha-tripeptide. These compounds are expected to be used in boron neutron capture therapy, chemotherapy, and synthesis of functional materials. (C) 2020 Elsevier Ltd. All rights reserved.

Antioxidant and alpha-Glucosidase Inhibitory Activities Guided Isolation and Identification of Components from Mango Seed Kernel

In the present study, petroleum ether, dichloromethane, ethyl acetate, and n-butanol fractions of mango seed kernel exhibited different degrees of antioxidant and alpha-glucosidase inhibitory activity. Thus, quantitative and qualitative analysis of the petroleum ether fraction was conducted by GC-MS. Among identified components, four unsaturated fatty acids had never been reported in natural products before, together with 19 known components. In addition, 17 compounds were isolated and elucidated from other active fractions. Compounds 2, 9, 15, and 17 were isolated for the first time from Mangifera genus. Compounds 1 and 2 exhibited prominent DPPH radical scavenging and alpha-glucosidase inhibitory effects. In order to further explore their mechanism of alpha-glucosidase inhibition, their enzyme kinetics and in silico modeling experiments were performed. The results indicated that 1 inhibited alpha-glucosidase in a noncompetitive manner, whereas 2 acted in a competitive manner. In molecular docking, the stability of binding was enhanced by pi-pi T-shaped, pi-alkyl, pi-pi stacked, hydrogen bond, and electrostatic interactions. Thus, compounds 1 and 2 were determined to be new potent antioxidant and alpha-glucosidase inhibitors for preventing food oxidation and enhancing hypoglycemic activity.

Effect of processing methods on the volatile components of Ethmalosa fimbriata using a two-dimensional gas chromatography-time-of-flight mass spectrometry (GC x GC-TOF-MS) technique

Changes in fish odor are attributed to volatile compounds’ generation. In this study, the effect of three processing methods (boiling, sun-drying, and smoke-drying) on the volatile compounds produced from Ethmalosa fimbriata was investigated using two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC x GC-TOF-MS). For complete cooking, appropriate fish samples were boiled slowly in water, while sun-drying was achieved traditionally. An improved Altona-type smoking oven was utilized for the smoke-drying process. The experimental results revealed the production of alkene, alkyne, alcohol, ketone, acids, esters, amines, sulfur-containing, and miscellaneous volatile compounds. Although the selected processing methods were effective for preserving E. fimbriata from the release of some volatile compounds associated with fish spoilage, they also contributed to the release of other volatile compounds and odor production. Boiling and smoke-drying were specifically found to be efficient for the removal of the three amines detected in the fresh fish sample, including carcinogenic N-nitrosodimethylamine. Practical applications The current research describes the potential of the studied processing methods (boiling, sun-drying, and smoke-drying) to preserve E. fimbriata from the production of some volatile compounds associated with fish spoilage. Boiling and smoke-drying were specifically found promising for preserving fish against the release of carcinogenic N-nitrosodimethylamine.

Larval energetics of the Sydney rock oyster Saccostrea glomerata and Pacific oyster Magallana gigas

Larvae are a critical dispersal stage of marine invertebrates, and their survival depends on nutrition and energetics. This study compared the size, survival, metabolic rate and egg and larval lipid class profiles of larvae of the endemic Sydney rock oyster Saccostrea glomerata and the invasive Pacific oyster Magallana gigas through a period of starvation for 5 and 9 d after fertilisation. Starved larvae grew without food until 5 d of age, at which point they stopped developing, but resumed growth when fed. Egg lipids profiles comprised 78.1 and 74.5% triacylglycerol for M. gigas and S. glomerata respectively. When fed, larvae of M. gigas were significantly larger in size and had faster growth and similar survival compared to S. glomerata. When starved, larvae of M. gigas and S. glomerata grew at similar rates, and there was a trend for lower survival of M. gigas. Larval endogenous lipid reserves were deleted in the first 24 h. Larvae of M. gigas had more total lipids and comparatively more diacylglycerols, monoacylglycerols, phospholipids and cholesterol, whereas S. glomerata had more diacylglycerols and produced sterol esters. Starvation altered the patterns of lipid assimilation, and metabolic rates of larvae of M. gigas and S. glomerata differed over time. When starved, S. glomerata larvae had greater capacity to cope with starvation compared to M. gigas, perhaps due to an evolutionary history in oligotrophic estuaries. As the climate rapidly changes in this global climate-change hotspot, S. glomerata is likely to be negatively affected.

Cholesterol in the Viral Membrane is a Molecular Switch Governing HIV-1 Env Clustering

HIV-1 entry requires the redistribution of envelope glycoproteins (Env) into a cluster and the presence of cholesterol (chol) in the viral membrane. However, the molecular mechanisms underlying the specific role of chol in infectivity and the driving force behind Env clustering remain unknown. Here, gp41 is demonstrated to directly interact with chol in the viral membrane via residues 751-854 in the cytoplasmic tail (CT751-854). Super-resolution stimulated emission depletion (STED) nanoscopy analysis of Env distribution further demonstrates that both truncation of gp41 CT751-854 and depletion of chol leads to dispersion of Env clusters in the viral membrane and inhibition of virus entry. This work reveals a direct interaction of gp41 CT with chol and indicates that this interaction is an important orchestrator of Env clustering.

Degradable and curable poly(conjugated ester)s prepared by acryl- and conjugate-substitutions of the ‘smallest’ monomer

alpha-(Chloromethyl)acryloyl chloride was polymerized with various bisphenols and diamines to yield poly(conjugated ester)s. The polymer prepared from bisphenol Z underwent curing by heating at 170 degrees C, while copolymerization with methyl methacrylate afforded a crosslinked polymer. The poly(conjugated ester)s were chemically decomposed via main-chain scission by the conjugate substitution with benzyl mercaptan. Moreover, the treatment with 5 wt% aqueous ammonia resulted in complete main-chain scission to the monomeric units by conjugate substitution and acyl substitution reaction, recovering bisphenol Z. Although curing and main-chain scission resulted in contractive changes on polymer properties, both reactions were achieved by a same skeleton, alpha-(aryloxymethyl)acrylate. Thus, alpha-(chloromethyl)acryloyl chloride is the smallest monomer to incorporate such a curable and degradable skeleton.

Organocatalytic Polymerization of Morpholine-2,5-diones toward Methionine-Containing Poly(ester amide)s: Preparation and Facile Functionalization

Methionine-containing poly(ester amide)s (PEAs) were potentially attractive biodegradable materials whose postpolymerization modification via methionine click enlarges the scope of poly(ester amide)s but were surprisingly unexplored. In this manuscript, the controlled organocatalytic ring-opening polymerization (ROP) of methionine-derived morpholine-2,5-diones (MDs) was implemented utilizing 1,8-diazabicyclo[5.4.0]undec-7-ene/thiourea (DBU/TU) binary organocatalytic system. A range of methionine-containing poly(ester amide)s having molecular weights (MWs) between 8.1 and 28.2 kg mol(-1) were thus generated with low distributions (D = 1.07-1.12). Moreover, the obtained poly(ester amide)s could undergo postpolymerization modification by methionine click functionalization to generate poly(ester amides with a range of functionality in a facile procedure. Finally, the obtained poly(ester amide)s exhibited variable glass transition temperatures and could be manufactured into transparent films by hot compression, demonstrating their great potential for applications.
