Synthesis, characterization and catalytic activity of PEPPSI-type palladium-NHC complexes

Eight benzimidazolium salts (2a-h) with two nitrogen atoms substituted by various alkyl groups have been synthesized in high yields. The benzimidazolium salts were readily converted into the corresponding PEPPSItype palladium-NHC complexes (PEPPSI = pyridine-enhanced precatalyst preparation, stabilization, and initiation) (3a-h). The structures of all compounds were characterized by H-1 NMR, C-13 NMR, and IR spectroscopy as well as by elemental analysis techniques, which support the proposed structures. The catalytic activity of the PEPPSI-type palladium-NHC complexes was evaluated with respect to the direct C5-arylation of 2-substituted heteroaryl derivatives (thiophene, furan and thiazole) with various aryl bromides. This arylation occurs efficiently and selectively at the C5-position of the 2-substituted thiophene, furan and thiazole derivatives.

Thiazole-Modified C3N4 Interfacial Layer for Defect Passivation and Charge Transport Promotion in Perovskite Solar Cells

Despite the conspicuous achievements in perovskite solar cells (PSCs), further improvement of the power conversion efficiency (PCE) is hindered by substantially detrimental carrier recombination resulting from the high interfacial charge defect density and inferior charge transport kinetics. Herein, an interface engineering strategy is developed to introduce a Lewis base thiophene or thiazole-modified C3N4 layer at the electron transfer layer (ETL)/perovskite interface to constitute a stepwise energy band alignment and passivate defects at interfaces of the perovskite film. Attributed to its well-matched energy level with TiO2 and perovskite, the charge extraction efficiency and charge transfer dynamics can be promoted remarkably, greatly inhibiting charge recombination at the interface. Furthermore, thiophene and thiazole can donate the lone pair electrons in S or N atoms to undercoordinated Pb2+, which effectively passivates the electronic trap states caused by halogen vacancies, thereby greatly minimizing trap-assisted nonradiative recombination in the PSCs. Eventually, the thiazole-C3N4/perovskite-based devices acquire an outstanding efficiency of 19.23%, supported by an enhanced open-circuit voltage (V-OC) of 1.11 V with improved moisture stability. This work provides an avenue for interfacial energy level modulation and defect passivation strategies for a rational interface microstructure design for meliorating the performance of PSCs.

Green Synthesis of 2,2 ‘-Bibenzazole and Its Polymers by Using Hexachloroacetone as C2 Synthon

A novel cyclization reaction by using hexachloroacetone as C2 synthon has been studied. The optimal condition was obtained by synthesis of bibenzothiazole in the presence hexachloroacetone in water. Experimental results showed that the nucleophilicity of substrates played a key role in the cyclization reaction, and catalytical amount of oxygen in reactions was also vital to trigger ring fusion in the formation of target compounds. Accordingly, the mechanism of cyclization reaction was proposed: the thiazole ring is formed in the first place by a nucleophillic attack of 2-aminobenzenethiol, followed by CCl3 cleavage from hexachloroacetone. Then the second 2-aminobenzenethiol launches another nucleophilic attack, and three chloride ions leave to form the second thiazole ring. The method was applied to the substrates of 2,5-diaminobenzene-1,4-dithiol and benzene-1,2,4,5-tetraamine, respectively and two polymers of polyphenylene dithiazole and polyphenylene diimidazole were successfully prepared. The experimental conditions were mild, the yield was high and the application value was high.

Experimental and theoretical studies of 2-Mercaptobenzothiazole with 2-Bromomethylmesitylene and 1,4-Bis(bromomethyl)durene

Biologically important 2-(2,4,6-trimethylbenzylthio)benzo[d]thiazole[BTM1] and 2-(4-((benzo[d]thiazol-2-ylthio)methyl)-2,3,5,6-tetramethylbenzylthio)benzo[d]thiazole [BTD2] were synthesized and characterised using FT-IR, NMR and single-crystal XRD (SCXRD). SCXRD revealed that both compounds were crystallized as a triclinic system and were associated through weak intermolecular interactions like H-bondings (CH center dot center dot center dot N, sp(3)-, and sp(2)-CH center dot center dot center dot pi), pi-pi stackings and Vander Waals interactions. These weak intermolecular interactions in BTM1 and BTD2 were studied using Crystal Explorer and Gaussian. The interaction of title compounds with epidermal growth factor receptor (EGFR)tyrosine kinase protein was performed using AutoDock Vina. Molecular docking study revealed an efficient interaction of compounds with the protein resulting in good anti-cancer activity. DNA binding studies were explored against calf thymus (CT) DNA using a spectrophotometric titration method and was found that benzothiazole compounds showed hyperchromism and good binding efficiency. In-vitro anti-microbial activities against some bacterial and fungal strains were investigated. BTMlexhibited a better inhibition against bacterial (Bacillus subtilis and Staphylococcus aureus) and fungal (Aspergillus niger) strains than BTD2. (C) 2020 Elsevier B.V. All rights reserved.

Physicochemical, optical and electrical investigation on poly [(phenylene-2-one)-co-(thiophene)] novel soluble conductive polymer as-synthesized through heterogeneous catalysis route

Although the use of conductive polymers has invaded the electronics industry, the insolubility parameter presents a major problem against their direct application on the surfaces of materials. Attachment of cyclic compounds to polymer chains is recommended to increase the solubility of conductive polymers. The aim of this study is to synthesize a new type of intrinsic conductive polymer, soluble in common solvents. The technique is based on the copolymerization of thiophene with a synthesized monomer phenylazepane-2-one. The reaction was catalyzed by a solid catalyst, prepared by the acid treatment of natural clay, generating active sites responsible for the adhesion of the thiophene and benzene rings. Proton and carbon nuclear magnetic resonances (H-1 NMR/C-13 NMR), ultraviolet spectroscopy (UV-Visible), infrared spectroscopy (IR) and differential scanning calorimetry (DSC) were used to identify the material obtained poly [(phenylazepane-2-one)-co-(thiophene)] abbreviated poly (PAT). Thermogravimetric analysis (TGA) showed the thermal stability of poly (PAT) before 200 degrees C. The solubility of poly (PAT) has been tested and confirmed in various common solvents. The indirect bandgap was calculated at 1.12 eV using Tauc formula. Ac electrical conductivity and dielectric permittivity have been studied versus frequency and temperature, showing the semiconductor character of poly (PAT). The results obtained showed that this novel polymer can play a pioneering role to replace conventional insoluble conducting polymers.

Design, synthesis, biological evaluation, QSAR analysis and molecular modelling of new thiazol-benzimidazoles as EGFR inhibitors

Heterocyclic rings such as thiazole and benzimidazole are considered as privileged structures, since they constitute several FDA-approved drugs for cancer treatment. In this work, a new set of 2-(2-(substituted) hydrazinyl)-4-(1-methyl-1H-benzo[d]imidazol-2-yl) thiazoles 4a-q were designed as epidermal growth factor receptor (EGFR) inhibitors and synthesized using concise synthetic methods. The new target compounds have been evaluated in vitro for their suppression activity against EGFR TK. Compounds 4n, 4h, 4i, 4a and 4d exhibited significant potency in comparison with erlotinib which served as a reference drug (IC50, 71.67-152.59 nM; IC50 erlotinib, 152.59 nM). Furthermore, MTT assay revealed that compounds 4j, 4a, 4f, 4h, 4n produced the most promising cytotoxic potency against the human breast cancer cell line (MCF-7) (IC50; 5.96-11.91 mu M; IC50 erlotinib; 4.15 mu M). Compound 4a showed promising activity as EGFR TK inhibitor as well as anti-breast cancer agent. In addition, 4a induced apoptotic effect and cell cycle arrest at G2/M phase preventing the mitotic cycle in MCF-7 cells. Moreover, 4a upregulated the oncogenic parameters; caspase-3, p53, Bax/Bcl-2 as well as it inhibited the level of PARP-1 enzyme. QSAR study was carried out for the new derivatives and it revealed the goodness of the models. Furthermore, molecular docking studies represented the binding modes of the promising compounds in the active pocket of EGFR.

Synthesis of thiazole linked chalcones and their pyrimidine analogues as anticancer agents

A series of nine novel thiazole linked chalcones, (E)-3-(4-methyl-2-(4(trifluoromethyl)phenyl)thiazol-5-yl)-1-phenylprop-2-en-1-one derivatives 7-15 were synthesized. To establish the structure-activity relationship (SAR), furthermore, the corresponding, ring-closed pyrimidine analogs 17-23 were synthesized. The derivatives thus obtained were evaluated for their anti-cancer activity against three genetically different colorectal cancer (CRC) cell lines. Thiazole derivatives 7, 9, and10 showed anti-cancer activity with GI50 values ranging from 0.19 to 100 mu M. Importantly, compounds 7 and 10 outperformed the standard drug cisplatin in the tested cell lines and thus show promise for further optimization. Some of pyrimidine derivatives retain activity comparable to cisplatin in the HT-29 cell line, e.g. compounds 17 and 18 with IC50 of 25 mu M, however, none of these compounds demonstrated improved antiproliferative activity as compared with the starting thiazole, thus the enone linker was critical for obtaining more active compounds in this series.

Characterization of the Stereoselective P450 Enzyme BotCYP Enables the In Vitro Biosynthesis of the Bottromycin Core Scaffold

Bottromycins are ribosomally synthesized and post-translationally modified peptide natural product antibiotics that are effective against high-priority human pathogens such as methicillin-resistant Staphylococcus aureus. The total synthesis of bottromycins involves at least 17 steps, with a poor overall yield. Here, we report the characterization of the cytochrome P450 enzyme BotCYP from a bottromycin biosynthetic gene cluster. We determined the structure of a close BotCYP homolog and used our data to conduct the first large-scale survey of P450 enzymes associated with RiPP biosynthetic gene clusters. We demonstrate that BotCYP converts a C-terminal thiazoline to a thiazole via an oxidative decarboxylation reaction and provides stereochemical resolution for the pathway. Our data enable the two-pot in vitro production of the bottromycin core scaffold and may allow the rapid generation of bottromycin analogues for compound development.

Comparison of benzothiazole-based dyes for sensitive DNA detection

For efficient and quantitative DNA detection, fluorescence staining is the most often explored approach, which relies on non-covalent binding of dyes with double stranded DNA (dsDNA). Ethidium bromide (EB) is the most classic DNA stain, but suffers from its high carcinogenicity. A series of less toxic alternatives were developed, many of which contain the core structure of the benzothiazole ring. However, the relationship between the structure and the DNA detection performance was not illustrated. Herein, five benzothiazole dyes, namely thiazole orange, SYBR Green I, PicoGreen, SYBR Safe, and thioflavine-T, were compared for DNA detection through direct fluorescence and gel electrophoresis, with particular focus on the structure-performance relationship. It turned out that SYBR Green I is currently the best choice for DNA detection. The results in this work may be useful for future DNA-staining dye developments.

Novel Quinoline-Based Thiazole Derivatives for Selective Detection of Fe3+, Fe2+, and Cu2+ Ions

New quinoline-based thiazole derivatives QPT and QBT were synthesized and characterized by various spectroscopic and single-crystal X-ray crystallographic studies. The metal-sensing properties of the probes were further examined by absorption and fluorescence spectrometry. The fluorescence intensity of QPT and QBT was remarkably quenched during the addition of Fe3+, Fe2+, and Cu2+ ions in THE/H2O (1:1) at pH = 7.4 in HEPES buffer, while the addition of other metal ions did not affect the fluorescence intensity of the ligands. The detection ability of the probes QPT and QBT was further investigated by titration with various equivalents of metal ions, optimized pH ranges for detection, and reversibility with Na(2)EDTA for biological applications.
