The effect of introducing a lateral methyl substituent and the two different alkoxy terminal groups on the mesophase behavior of three-benzene-ring molecular core of azo-ester compounds bearing 2-methylbutoxy unit on the opposite terminal side (C1-C6) were explored. Their structures were confirmed by several spectroscopic techniques (Fourier transform infrared spectroscopy, H-1 and C-13 nuclear magnetic resonance spectroscopy). The mesomorphic properties of these compounds were studied by differential scanning calorimetry, polarized optical microscopy, and small- and wide-angle X-ray scattering. Except for the un-substituted terminals (C1 and C4), all other derivatives are liquid crystalline, exhibiting enantiotropic nematic liquid crystal phase. The alteration of the alkoxy chain length from methoxy to butoxy at the phenyl ester terminal group (ring A) for each set of laterally-neat and laterally methyl-substituted mesogens decreases the nematic temperature range. A decrease in the mesophase temperature range is also observed when a lateral methyl substituent is incorporated into phenylazo ring of the mesogenic core (ring C). Optical study demonstrated that their absorption spectra are identical in shape due to the structural similarities of the mesogenic core. The corresponding fluorescence spectra exhibited blue-emission with the laterally methyl substituted compounds having a relatively higher fluorescence intensity compared to that of its laterally un-substituted analogues. Furthermore, the laterally methyl-substituted derivatives were subjected to the planar alignment and their dielectric and electro-optic properties were investigated. The nematic phase of the aligned samples shows antiferroelectric switching behavior with spontaneous polarization, P-s similar to 5 mu C/cm(2). (C) 2021 Elsevier B.V. All rights reserved.

Naturally occurring benzoic acid (BA) derived anions have been used to prepare halogen free hydrophilic ionic liquids (ILs 1-4). The supramolecular polymeric aggregation behaviour of these ILs has been studied through high-resolution electron spray ionization mass spectrometry (HR-ESI-MS). Furthermore, these ILs were applied as catalyst/phase transfer catalyst in the synthesis of tetrahydrobenzo[b]pyran and its derivatives. These reactions were conducted in aqueous medium under ultrasound assistance. The results suggested that 1-ethyl-3-methylimidazolium 2-hydroxybenzoate (IL-1) was a highly efficient catalyst yielding 86.9% product in 30 min. In addition, the impact of aggregation behaviour of ILs on their catalytic activity was also investigated. (C) 2021 Elsevier B.V. All rights reserved.

We aim at encapsulating fragrances made of a variety of lipophilic species to slow down their diffusion. Our strategy is to develop capsules by polymerizing the water intermediate phase of an oil-in-water-in-oil double emulsion. In other terms, our system consists in a direct emulsion of fragrance (O1) in a water phase (W) containing monomer, initiator, and cross-linker. To obtain the double emulsion, this direct emulsion, stabilized by a hydrophilic surfactant, is itself dispersed in an external lipophilic solvent used in perfumery (O2) and stabilized by a lipophilic surfactant. Polymerization of the intermediate water phase aims at obtaining a 3D network. Differently from nowadays-proposed capsules, this strategy allows polymerization only taking place in the water phase rather in the phase containing the fragrance. Moreover, the obtained 3D network is supposed to play the role of an effective barrier limiting the diffusion of the inner lipophilic species towards either the external solvent or air. Such an approach implies the combination of a formulation step to elaborate the double emulsion using two antagonistic surfactants, a hydrophilic one and a lipophilic one, and of the polymerization of the intermediate phase. Insertion of the polymerizable species in the double emulsion shall not destabilize it. Some monomers exhibiting interfacial affinity and interfering with the formulation of the double emulsion have to be avoided. By varying the nature of the monomers and the cross-linker to monomer ratio, capsules with high encapsulation efficiencies and with various mechanical properties have been obtained.

Apios americana Medik, a native American plant has potential as a commercially viable Northern European-grown motcrop, mainly due to its resistance to extreme climate and nutritional quality. Analysis of A. americana sourced from two UK sites; South (51.4690 degrees N, 1.1150 degrees W) and North (55.9661 degrees N, 3.2063 degrees W) showed that the tubers were a complete source of amino acids (UPLC-TUV analysis), were rich in protein (15.0 +/- 0.0160 and 17.3 +/- 0.0779%; Vario Max CN analysis), fibre (total non-starch polysaccharides, 10.4 +/- 0.570 and 10.6 +/- 0.280%; GC analysis) and micronutrients (calcium, manganese, iron, zinc, molybdenum, potassium and phosphorus; ICP-MS analysis). Apios americana tubers were also rich in bioactive phytochemicals. From the 156 plant metabolites measured using LC-MS/MS analysis, genistein was the major phytophenol in both the Southern- and Northern UK tubers (259 +/- 12.2 mg Kg(-1) and 356 +/- 29.9 mg Kg(-1) respectively); the peel having similar phytochemical profiles. The protein and fibre content of the leaves (17.3 +/- 0.0434% and 11.7 0.0445%) and rhizomes (18.4 +/- 0.0152% and 13.5 +/- 0.590%) were significantly higher (p < 0.05) than the tubers. The leaves were also a good source of anthocyanins; delphinidin and cyanidin (840 +/- 137 and 3934 +/- 176 mg Kg(-1) respectively). Cultivation of A. americana as a high-protein staple-crop has enormous potential in Northern European countries for human nutrition, diet diversification, and use in livestock diets.

Two new series of diethyl 2-[2-(substituted-2-oxo-1,2-dihydroquinolin-4-yl)hydrazono]-succinates 6a-g and 1-(2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazoles 7a-f have been designed and synthesized. The structures of the synthesized compounds were proved by IR, mass, NMR (2D) spectra and elemental analyses. The target compounds were evaluated for their in vitro cytotoxic activity against 60 cancer cell lines according to NCI protocol. Consequently, seven compounds were further examined against the most sensitive cell lines, leukemia CCRFCEM, and MOLT-4. 5-Amino-1-(6-bromo-2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazole-3,4-dicarbonitrile (7f) was the most active product, with IC50= 1.35 uM and 2.42 uM against MOLT-4 and CCRF-CEM, respectively. Also, it showed a remarkable inhibitory activity compared to erlotinib on the EGFR TK with IC50 = 247.14 nM and 208.42 nM, respectively. Cell cycle analysis of MOLT-4 cells treated with 7f showed cell cycle arrest at G2/M phase (supported by Caspases, BAX and Bcl-2 studies) with a significant pro-apoptotic activity as indicated by annexin V-FITC staining. Moreover, the docking study indicated that both the pyrazole moiety and the quinolin-2-one ring showed good fitting into EGFR (PDB code: 1M17). In order to interpret SAR of the designed compounds, and provide a basis for further optimization, molecular docking of the synthesized compounds to known EGFR inhibitors was performed. The study illustrated the effect of several factors on the compounds’ activity.

We report the synthesis and first characterisation of the novel chemical probe 3-bromotetrazine and establish its reactivity towards nucleophiles. This led to the synthesis of several novel classes of 3-monosubstituted s-tetrazines. A remarkable functional group selectivity is observed and is utilised to site-selectively functionalise different complex molecules. The stability of 3-bromotetrazine under the reaction conditions facilitated the development of a protocol for protein functionalisation, which enabled a minimal, bifunctional tetrazine unit as a bio-orthogonal handle for inverse electron demand Diels-Alder reactions. Additionally, a novel tetrazine-based chemical probe was developed and its application in the context of thiol-targeted natural product isolation and labelling of mammalian cells is demonstrated.

Quinoline derivatives are attracting considerable interest due to their biological importance. In this paper, several 2-amino-4-aryl-6-(quinolin-2-ylthio)pyridine-3,5-dicarbonitrile derivatives are synthesized by adopting a one-pot reaction of quinoline-2-thione, aromatic aldehydes, and malononitrile in the presence of sodium hydroxide in absolute ethanol. The structures of these newly synthesized compounds were determined using different spectroscopic techniques, including elemental analyses, IR,H-1 NMR, and MS. The synthesized derivatives were screened for their antimicrobial and cytotoxic activities. Compounds4a,4b,4d, and4eexhibited promising antimicrobial activity compared to antibacterial and antifungal standard drugs. Additionally,4f,4d, and4gshowed potent cytotoxic activity against both MCF-7 and A549 cells with IC(50)values (6.39-9.3 mu M). Our molecular docking results of compound4fprove good binding affinity toward the three tested proteins as Jak2/STATA3 inhibition and are in accordance with the RT-PCR mRNA expressions of the compound against MCF-7 cells which downregulated the Jak2 and STAT3 genes, and this may be the proposed mode of action for anti-breast cancer activity.
