Azathioprine Electrochemical Adsorption onto the Reduced Graphene Oxide Sheets in Absence and in the Presence of Polyaniline

The azathioprine (AZA) electrochemical adsorption onto the screen-printed carbon electrodes (SPCE) modified with the reduced graphene oxide (RGO) sheets in the absence and in the presence of polyaniline-emeraldine salt (PANI-ES) is reported in this work. Using cyclic voltammetry(CV), in the case of the SPCE modified with the RGO sheets non-functionalized and functionalized with PANI-ES, respectively, an irreversible process at the electrode/electrolyte interface is highlighted to take place. In the case of the SPCE modified with the non-functionalized RGO sheets(SPCE-RGO), the oxidation-reduction processes induce an up-shift of the AZA Raman lines from 856 and 1011 cm(-1) to 863 and 1020 cm(-1), respectively. These variations indicate an AZA adsorption onto the surface of the SPCE modified with the RGO sheets that takes place throughtthe imidazole and pyrimidine cycles of mercaptopurine, when the generation of the pi-pi(*) bonds between the mercaptopurine structure and hexagonal carbon cycles of RGO occurs. The electrochemical functionalization of the RGO sheets with PANI-ES is proved bythe appearance of the Raman lines at 1165, 1332-1371, 1496 and 1585 and 1616 cm(-1). The oxidation-reduction processes induced at the interface of the SPCE modified with PANI-ES functionalized RGO sheets and the electrolyte consisting into a phosphate buffer (PB) and AZA lead to thegeneration of new positive charges onto the PANI macromolecular chain and the adsorption of the drug on the working electrode surface that takes place via the pi-pi(*) bonds established between the benzene/quinoide rings of PANI and the imidazole/ purine cyclesof AZA. These results indicate that the SPCE modified with the PANI-ES functionalized RGO sheets shows potential applications in the field of sensors for AZA detection.

Pronounced Solvent Effect on the Composition of Binary Self-Assembled Monolayers with Embedded Dipole Moments

The formation and properties of binary thiolate self-assembled monolayers (SAMs), comprised of precursors featuring a short heteroaromatic backbone, consisting of a nonpolar phenyl ring and a polar pyrimidine group, embedded in two opposite orientations, were investigated in the context of work function engineering. The SAMs were prepared by coadsorption of both constituents dissolved in either tetrahydrofuran (THF) or ethanol, exhibiting a strong solvent effect. In the case of THF, the SAM composition nearly mimicked that of the primary solutions, with a slight preference of the 50%-50% relation, which was accompanied by the respective gradual variation of the work function, allowing its fine-tuning within the 4.0-4.9 eV range for Au(111). In the case of ethanol, a strongly preferential adsorption of one of the components was observed, limiting significantly the range of the work function variation. The effect of the solvent was tentatively explained by the different abilities of THF and ethanol to build hydrogen bonds to the SAM precursors, affecting their adsorption and self-assembly behavior. The composition and morphology of the binary SAMs were monitored by the electrostatic effects in photoemission, manifesting these effects as a useful experimental tool and a fingerprint parameter for the work function estimation.

On water synthesis of the novel 2-oxo-1,2,3,4-tetrahydropyrimidines

A simple on water approach for the synthesis of novel tetrahydropyrimidine (THPM) derivatives has been developed under a green and sustainable fashion. For the first time, a deuterated Biginelli’s hybrid was synthesized. Novel THPMs are suitable for further derivatization and could be an excellent toolkit for lead-oriented synthesis and/or cross-coupling reactions. (C) 2020 Elsevier Ltd. All rights reserved.

The use of tissue-engineered skin to demonstrate the negative effect of CXCL5 on epidermal ultraviolet radiation-induced cyclobutane pyrimidine dimer repair efficiency

Background Ultraviolet radiation (UVR) is responsible for keratinocyte cancers through the induction of mutagenic cyclobutane pyrimidine dimers (CPDs). Many factors influence CPD repair in epidermal keratinocytes, and a better understanding of those factors might lead to prevention strategies against skin cancer. Objectives To evaluate the impact of dermal components on epidermal CPD repair efficiency and to investigate potential factors responsible for the dermal-epidermal crosstalk modulating UVR-induced DNA damage repair in keratinocytes. Methods A model of self-assembled tissue-engineered skin containing human primary keratinocytes and fibroblasts was used in this study. Results We showed that CPD repair in keratinocytes is positively influenced by the presence of a dermis. We investigated the secretome and found that the cytokine CXCL5 is virtually absent from the culture medium of reconstructed skin, compared with media from fibroblasts and keratinocytes alone. By modulating CXCL5 levels in culture media of keratinocytes, we have shown that CXCL5 is an inhibitor of CPD repair. Conclusions This work outlines the impact of the secreted dermal components on epidermal UVR-induced DNA damage repair and sheds light on a novel role of CXCL5 in CPD repair.

Extended ligand conjugation and dinuclearity as a route to efficient platinum-based near-infrared (NIR) triplet emitters and solution-processed NIR-OLEDs

Near infrared (NIR) emission from molecular materials is typically targeted by using more extended conjugated systems compared to visible-emitting materials. But efficiencies usually fall off due to the combined effects of increasing non-radiative and lower oscillator strengths as the energy of emissive excited states decreases. Efficient NIR-emitting organic light emitting diodes (OLEDs) are rare compared to the huge progress that has been made for visible-light devices. For organometallic emitters that contain a heavy metal ion to promote phosphorescence through the effect of enhanced spin-orbit coupling (SOC), the problem is typically exacerbated by decreased metal character in the S-n and T-1 excited states as the conjugation in a bound ligand increases. Here we show how the use of a dinuclear metal complex with an extended conjugated ligand allows such effects to be mitigated compared to analogous structures with just one metal centre. The complex Pt-2(bis-dthpym)(dpm)(2) (complex 5) is readily prepared by a double N<^>C cyclometallation of 4,6-bis(dithienyl)-pyrimidine (H(2)bis-dthpym), with the coordination sphere of each Pt centre being completed by O<^>O-coordinating dipivaloylmethane (dpm). This new complex displays intense NIR emission in solution, lambda(max) = 725 nm, with essentially no contamination by visible light <700 nm. The photoluminescence quantum yield of 0.17 in toluene at 300 K is vastly superior to that of the analogous mononuclear complex, where reduced SOC leads primarily to ligand-based fluorescence and only very weak phosphorescence. Computational results indicate that a key reason for the superior performance of the dinuclear system is a doubling of the number of higher-lying excited singlet states with which the T-1 state may couple, to promote the formally forbidden phosphorescence process. Complex 5 has been evaluated as an NIR emitter in solution-processed OLEDs. An external quantum efficiency (EQE) of 3.6% is attained using 5 doped into TBP:PBD at 5% w/w, with a turn-on voltage of 5.6 V (at 0.01 mW cm(-2)). The maximum radiosity of 2.7 mW cm(-2) for this device is particularly high compared to most reported NIR-emitting phosphorescent OLEDs.

Repurposing INCI-registered compounds as skin prebiotics for probiotic Staphylococcus epidermidis against UV-B

Repurposing existing compounds for new indications may facilitate the discovery of skin prebiotics which have not been well defined. Four compounds that have been registered by the International Nomenclature of Cosmetic Ingredients (INCI) were included to study their abilities to induce the fermentation of Staphylococcusepidermidis (S. epidermidis), a bacterial species abundant in the human skin. Liquid coco-caprylate/caprate (LCC), originally used as an emollient, effectively initiated the fermentation of S. epidermidis ATCC 12228, produced short-chain fatty acids (SCFAs), and provoked robust electricity. Application of LCC plus electrogenic S. epidermidis ATCC 12228 on mouse skin significantly reduced ultraviolet B (UV-B)-induced injuries which were evaluated by the formation of 4-hydroxynonenal (4-HNE), cyclobutane pyrimidine dimers (CPD), and skin lesions. A S. epidermidis S2 isolate with low expressions of genes encoding pyruvate dehydrogenase (pdh), and phosphate acetyltransferase (pta) was found to be poorly electrogenic. The protective action of electrogenic S. epidermidis against UV-B-induced skin injuries was considerably suppressed when mouse skin was applied with LCC in combination with a poorly electrogenic S. epidermidis S2 isolate. Exploring new indication of LCC for promoting S. epidermidis against UV-B provided an example of repurposing INCI-registered compounds as skin prebiotics.

A 3D Adenine-based Cd-MOF: Synthesis, Structure and Photoluminescent Sensing for an Aromatic Azo Compound

A new Cd-MOF containing the nucleobase adenine and multicarboxylates, Cd-2(tdc)(2)(1H-ade)(2)(H2O) (H(2)tdc = 2,5-thiophene carboxylic acid, 1H-ade = adenine), was synthesized successfully under hydrothermal condition and characterized by single-crystal X-ray diffraction, infrared spectrum, thermogravimetric analysis and photoluminescence. The two crystallographically unsymmetrical Cd atoms are bridged by 2,5-tdc ligands with (kappa(1)-kappa(1))-(kappa(1))-mu(3) and (kappa(1)-kappa(1))-mu(2) modes into two dimensional extended layers, which are further pillared with the neutral ade molecules to form a 3D frameworks stabilized by extensive pi center dot center dot center dot pi interactions between imidazole-, pyrimidine- and thiophene-rings. Inspection of the structure reveals that the architecture can be simplified as a 3,4,5- connected networks with a Schlafli symbol of (6(2)center dot 8)(4(2)center dot 6(3)center dot 8)(4(2)center dot 6(5)center dot 8(3)). The photochemical property shows that the luminescent emission can be significantly quenched by aromatic azo compounds. The quenching effect coefficient (K-sv) for bis(4-imidazol-1-yl-phenyl)diazene is determined to be 4.1 x 10(4) m(-1), indicating the title compound as a potential fluorescent sensing materials.

Resorcin[4]arene-based Cu(I) binuclear and mononuclear complexes as efficient catalysts for azide-alkyne cycloaddition reactions

In this study, three fascinating resorcin[4]arene-based Cu(I) complexes, named [CuCl (TPC4R)] (1), [CuBr (TPC4R)] (2), and [Cu2I2(TPC4R)] (3) were prepared by using a pyrimidine-functionalized resorcin[4]arene ligand (TPC4R). In 1 and 2, two Cu(I) ions were linked by two TPC4R and two Cl- (or Br-) anions to form binuclear units. The adjacent units were extended into supramolecular layers through H bonds. In 3, two Cu(I) ions were connected by one TPC4R and two I- anions to form a mononuclear complex. The mononuclear units were connected by hydrogen bonds to produce a supramolecular chain. Significantly, 1 and 2 exhibit high efficiency and universality for azide-alkyne cycloaddition reactions in the synthesis 1,2,3-triazoles and beta-OH-1,2,3-triazoles. It has been found that the amount of catalyst, solvent type and reaction temperature have considerable influences on the activities of catalytic systems. The conversions of catalysts 1 and 2 could reach 99% for most of the selected substrates. It was found that after repeatedly used for 4 times, the catalytic activity of 1 did not decrease apparently.
