Probing the Interaction of Nucleobases and Fluorophore-Tagged Nucleobases with Graphene Surface: Adsorption and Fluorescence Studies

Adsorption of a fluorophore-labeled DNA oligonucleotide by graphene nano-probes is of interest to exploit as bio-sensing material. This work reports the fluorescence properties of fluorophore tagged nucleobases on the graphene surface computationally. The interaction of nucleobases and fluorophore tagged nucleobases to the graphene surface examined using M062X/6-31G(d) level of theory in the gas phase and ethanol solvent. The binding energies of nucleobases on the graphene surface in the gas phase follows the order: G>A >= C >= T in agreement with the previous reports. The slab model calculations performed with LDA/PWC/DND level of theory also revealed a similar binding affinity on the graphene surface in the gas phase. The fluorescence of benzoxazole as fluorophore tagged with nucleobase on graphene surface was investigated using TD-DFT M06-2X/6-31G(d) level of theory. The binding preference of the fluorophore tagged nucleobases is not significantly different in ethanol solvent. The aromaticity of the nucleobases tagged fluorophore on the graphene surface was investigated by NICS (1) and NICS (1)(zz) calculations and the aromaticity was found to be increased upon interaction with the graphene surface. The fluorescence quenching upon binding of fluorophore tagged nucleobases on graphene surface revealed the importance of purine nucleobases and found to be more prominent with guanine tagged fluorophore.

A new series of three-coordinate cuprous complexes formed by steric hindrance of a phosphine ligand: Synthesis, structure characterization, properties and TD-DFT calculations

Four new three-coordinate cuprous complexes with a CuN2P core, 1-QBO, 2-Phen, 3-MePBO, 4-QBI, were designed and synthesized by utilizing a steric hindrance of phosphine ligand o-Anisyl(3)P [QBO = 2-(2′-quinolyl)benzoxazole, Phen = 1,10-Phenanthroline, MePBO = 5-methyl-2-(2′-pyridyl)-benzoxazole, QBI = 2(2′-quinolyl)benzimidazole, o-Anisyl(3)P = tri(2-methoxyphenyl)-phosphine]. As a counterpart to 1-QBO, a four-coordinate complex 5-QBOP2 has also been synthesized with a CuN2P2 core. All complexes were characterized by single-crystal X-ray diffraction, spectroscopic analysis (IR, UV-Vis), elemental analysis, and photoluminescence study. Single-crystal X-ray diffraction revealed that complexes 1-4 all adopt trigonal CuN2P coordination geometry with one phosphine and one diimine ligand. Their UV-Vis absorption spectra exhibit concentration dependences of absorption edge shift. Time-dependent density functional theory (TD-DFT) calculations reveal that their S-1 states and the peak transition states can be mainly assigned as ligand-ligand & metal-ligand charge transfer (L’LCT + MLCT) and intra-ligand charge transfer (ILCT) states, respectively. It is noteworthy that all three-coordinate complexes 1-4 do not display obvious photoluminescence (PL), whereas the PL of four-coordinate complex 5 is turned on by an extra coordination of a phosphine ligand to 1. This PL complex has also been synthesized and characterized as 5-QBOP2 from 1-QBO. This model of three-coordinate to four-coordinate change with PL turn-on behavior could be used for sensing volatile organic compounds (VOCs). (C) 2019 Elsevier Ltd. All rights reserved.

Discovery of novel series of 2-substituted benzo[d]oxazol-5-amine derivatives as multi-target directed ligands for the treatment of Alzheimer’s disease

Alzheimer’s disease (AD) is associated with multifactorial neuropathological conditions, which include cholinergic deficit, amyloid-beta plaques formation, loss of neuronal plasticity and neuronal death. Treating such multifactorial conditions with a single target directed approach is considered to be inadequate. Accordingly, multi-target directed ligand (MTDL) strategy has been evolved as an auspicious approach for the treatment of AD. In light of that, a library of 2-substituted benzo[d]oxazol-5-amine derivatives (29-39; 86-107) was designed using the scaffold hopping guided MTDLs strategy, synthesized and evaluated through various in-vitro and in-vivo biological studies. The optimal compound 92 exhibited potent inhibitory activities against AChE (IC50 = 0.052 +/- 0.010 mu M), BuChE (IC50 = 1.085 +/- 0.035 mu M), and significant amyloid-beta aggregation (20 mu M) inhibition. The compound possessed better blood-brain barrier permeability (Pe = 10.80 +/- 0.055 x 10(-6) cm s(-1)) in PAMPA assay and neuro protective properties (40 mu M) on SH-SY5Y neuroblastoma cell lines. Furthermore, in-vivo behavioural studies were performed on Y-maze test (scopolamine-induced amnesia model) and Morris water maze test (A beta(1-42) induced ICV rat model). The compound 92, at a dose of 10 mg/kg oral administration, demonstrated a substantial improvement of the cognitive and special memory impairment. In summary, both in-vitro and in-vivo investigations evidenced that compound 92 was a potential lead for the discovery of safe and effective disease-modifying agents for AD.

Mesomorphic properties improved via lateral fluorine substituent on benzoxazole-terminated mesogenic compounds

Here, laterally monofluorinated heterocyclic mesogenic compounds, 2-[4-[2-[4-alkoxy-phenyl]ethynyl]-3-fluorophenyl]-benzoxazole derivatives (nPEFPBx) with hydrogen, methyl and nitro terminal substituents (coded as nPEFPBH, nPEFPBM and nPEFPBN, respectively) at 5-position of benzoxazole unit, are synthesised and characterised. They display enantiotropic nematic mesophase with mesophase ranges of 22-30 degrees C and 32-39 degrees C on heating and cooling for nPEFPBH, 67-92 degrees C and 87-115 degrees C for nPEFPBM, 31-84 degrees C and 42-51 degrees C for nPEFPBN (n < 7), respectively, which is better than nonfluorinated and laterally difluorinated analogous. Improved mesophase property is ascribed to reduced dipole moment resulting from introduction of lateral fluorine atom in opposite direction of polar benzoxazole unit. This indicates that monofluorine substituent contributes to improve nematic mesophase for benzoxazole-terminated mesogenic compounds. In addition, the compounds nPEFPBx have high birefringence of 0.513-0.650 because of large p-conjugated mesogenic core composed of benzene, ethynyl and benzoxazole groups, which suggests a possible application in liquid crystal mixture to enhance birefringence. Meanwhile, except nPEFPBN, the compounds nPEFPBx show intense photoluminescence emission at 406-407 nm in methylene chloride solution with exciting them at absorption maxima. [GRAPHICS] .

Effects of ionic liquid doping on gas transport properties of thermally rearranged poly(hydroxyimide)s

In this study we present a novel and simple approach to improve the gas separation performance of the thermally rearranged membranes, which involves doping the polyimide precursors (HPI) with ionic liquid (IL), and carrying out its degradation along with the conversion process to polybenzoxazole (PBO) in order to facilitate the formation of larger and /or more numerous free volumes. A series of aromatic (co)poly(hydroxyimide)s based on 6FDA and HAB/4MPD diamines in different molar ratios, as well as BPADA-HAB poly(hydroxyimide) were synthesized as the precursors to be doped with IL and thermally rearranged to PBO. The structural modifications of the precursor backbone were applied to study the impact of IL on the physical properties, thermal conversion process, as well as gas transport properties of the doped polymers with different chain rigidities. The pure and IL doped (co)polyimides and their thermally rearranged counterparts were characterized by WAXD, DSC, TGA, tensile tests, and PALS, and examined in pure gas permeation experiments. TR conversion temperature was considerably reduced by IL doping (e.g. by 126 degrees C). This effect depended on the precursor chemical structure and the IL content. After thermal rearrangement of the IL doped HPIs, the membrane permeability to gases increased significantly compared to the un-doped analogues (e.g. 2 fold increase for O-2 permeability). The permeability increase was larger for the higher IL content and the precursor chain rigidity. This was accompanied by a relatively small loss in selectivity leading to the performance shift towards the 2008 upper bound. The differences in permeability among the samples correlated with the free volume size from PALS. In particular, a very good correlation was obtained (r(2) = 0.958), when the data fitted to the Cohen-Turnbull model concerned only PBO samples with low cohesive energy density. Further studies on HPIs doped with IL with lower degradation temperatures are suggested to mitigate polymer degradation and explore this new method for the design of improved gas separation membrane materials.

Immunomodulatory and immunostimulatory effects of some bisbenzoxazole derivatives on lipopolysaccharide stimulated mammalian macrophages

Benzoxazoles and their derivatives have exerted anti-cancer and anti-inflammatory (immunomodulatory) potential due to their anti-proliferative effect on the cells. These molecules are DNA basebioisosteres, therefore, their mechanism of action could be by mimicking the structures of the DNA bases and halting the DNA polymerization processes. Based on their anti-proliferative effect, in our study we aimed to decipher the potential anti-inflammatory activities of unique bisbenzoxazole derivatives in vitro on mammalian macrophages. Being able to manipulate the inflammatory function of macrophages would enable the regulation of the immune response against danger stimuli. This would enable us better prognosis against different types of the diseases ranging from autoimmune disorders to cancer. Our results support the stark anti-inflammatory potential of bisbenzoxazole derivatives RHE 241 and RHE 248 in vitro on the LPS activated mammalian macrophages. After further delineation of their mechanism of action in vitro and their in vivo potency, these molecules could be utilized as potent anti-inflammatory medicines.
