Reaction of Pyridine-N-Oxides with Tertiary sp(2)-N-Nucleophiles: An Efficient Synthesis of Precursors for N-(Pyrid-2-yl)-Substituted N-Heterocyclic Carbenes

N-(Pyrid-2-yl)-substituted azolium and pyridinium salts, precursors for hybrid NHC-containing ligands, were obtained with excellent regioselectivity, employing a deoxygenative CH-functionalization of pyridine-N-oxides with substituted imidazoles, thiazoles, and pyridine. Unlike the traditional SNAr-based methods, this approach provides high yields for substrates bearing substituents of different electronic nature. The utility of azolium and pyridinium salts thus prepared was also highlighted by the synthesis of pyridyl-substituted imidazolyl-2-thione, benzodiazepine as well as 2-aminopyridines.

Inhibition of Ehrlich ascites cancer, hypoxia-inducible factor-1 alpha, and the kinase insert domain-containing receptor/fms-like tyrosine kinase-binding domains of vascular endothelial growth factor by Thiazole Acetamide Derivatives

Background: Tumor cells that have the ability to express vascular endothelial growth factor (VEGF) are more competent to growth and metastasize by the adequate amount of blood and oxygen supply by the blood vessels to the growing mass of cells. Hypoxic tumors are known for its aggressiveness and resistance to the treatment. Targeting VEGF and hypoxia-inducible factor-1 alpha (HIF-1 alpha) is an attractive strategy to interrupt the multiple pathways crucial for tumor growth. In the present study, two thiazole acetamide derivative’s anticancer property, anti VEGF and HIF-1 alpha inhibitory property were investigated. Methodology: Two thiazole acetamide compounds were synthesized, TA1 and TA2 and its anticancer property was studied in Erlich’s ascites cancer cells. To evaluate the anticancer property the assays such as 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, DNA diffusion assay for apoptosis, and lactate dehydrogenase leakage assay were carried out. The cell culture media was used to assess the secreted VEGF level. Molecular docking studies were performed to analyze the binding efficiency of the study compounds to the kinase insert domain-containing receptor (KDR) and fms-like tyrosine kinase (FLT)-binding domains of VEGF protein. HIF-1 alpha inhibitory study was performed by flow cytometry analysis using HUVEC cell line. Results: The study compounds inhibited HIF-1 alpha and VEGF secretion, these data shown positive prop up for the anticancer property of the derivatives. The docking studies showed moderate binding of study compounds to KDR and FLT-binding domains of VEGF protein. Conclusion: These results conclude the anticancer and anti-angiogenic property of the synthesized thiazole-acetamide derivatives.

Water-Soluble Iridium(III) Complexes Containing Tetraethylene-Glycol-Derivatized Bipyridine Ligands for Electrogenerated Chemiluminescence Detection

Four cationic heteroleptic iridium(III) complexes containing a 2,2 ‘-bipyridine (bpy) ligand with one or two tetraethylene glycol (TEG) groups attached in the 4 or 4,4 ‘ positions were synthesized to create new water-soluble electrogenerated chemiluminescence (ECL) luminophores bearing a convenient point of attachment for the development of ECL-labels. The novel TEG-derivatized bipyridines were incorporated into [Ir((CN)-N-perpendicular to)(2)(R-bpy-R ‘)]Cl complexes, where (CN)-N-perpendicular to = 2-phenylpyridine anion (ppy) or 2-phenylbenzo[d]thiazole anion (bt), through reaction with commercially available ([Ir((CN)-N-perpendicular to)(2)(mu-Cl)](2) dimers. The novel [Ir((CN)-N-perpendicular to)(2)(Me-bpy-TEG)]Cl and [Ir((CN)-N-perpendicular to)(2)(TEG-bpy-TEG)]Cl complexes in aqueous solution largely retained the redox potentials and emission spectra of the parent [Ir((CN)-N-perpendicular to)(2)(Me-bpy-Me)]PF6 (where Me-bpy-Me = 4,4 ‘ methyl-2,2 ‘-bipyridine) luminophores in acetonitrile, and exhibited ECL intensities similar to those of [Ru(bpy)(3)](2+) and the analogous [Ir((CN)-N-perpendicular to)(2)(pt-TEG]Cl complexes (where pt-TEG = 1-(TEG)-4-(2-pyridyl)-1,2,3-triazole). These complexes can be readily adapted for bioconjugation and considering the spectral distributions of [Ir(ppy)(2)(Me-bpy-TEG)](+) and [Ir(ppy)(2)(pt-TEG)](+), show a viable strategy to create ECL-labels with different emission colors from the same commercial [Ir(ppy)(2)(mu-Cl)](2) precursor.

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.

Chemical-informatics approach to COVID-19 drug discovery: Exploration of important fragments and data mining based prediction of some hits from natural origins as main protease (Mpro) inhibitors

As the world struggles against current global pandemic of novel coronavirus disease (COVID-19), it is challenging to trigger drug discovery efforts to search broad-spectrum antiviral agents. Thus, there is a need of strong and sustainable global collaborative works especially in terms of new and existing data analysis and sharing which will join the dots of knowledge gap. Our present chemical-informatics based data analysis approach is an attempt of application of previous activity data of SARS-CoV main protease (Mpro) inhibitors to accelerate the search of present SARS-CoV-2 Mpro inhibitors. The study design was composed of three major aspects: (1) classification QSAR based data mining of diverse SARS-CoV Mpro inhibitors, (2) identification of favourable and/or unfavourable molecular features/fingerprints/substructures regulating the Mpro inhibitory properties, (3) data mining based prediction to validate recently reported virtual hits from natural origin against SARS-CoV-2 Mpro enzyme. Our Structural and physico-chemical interpretation (SPCI) analysis suggested that heterocyclic nucleus like diazole, furan and pyridine have clear positive contribution while, thiophen, thiazole and pyrimidine may exhibit negative contribution to the SARS-CoV Mpro inhibition. Several Monte Carlo optimization based QSAR models were developed and the best model was used for screening of some natural product hits from recent publications. The resulted active molecules were analysed further from the aspects of fragment analysis. This approach set a stage for fragment exploration and QSAR based screening of active molecules against putative SARSCoV-2 Mpro enzyme. We believe the future in vitro and in vivo studies would provide more perspectives for anti-SARS-CoV-2 agents. (c) 2020 Elsevier B.V. All rights reserved.

Efficient synthesis and characterization of novel bis(chromenes) and bis(benzo[f]chromenes) linked to thiazole units

New carbothioamides, linked to chromene or benzo[f]chromene units, were taken as key synthons for the present study. These carbothioamides were prepared, in good yields, by the cyclocondensation of the appropriate 2-hydroxybenzaldehydes or 2-hydroxy-1-naphthaldehyde with 2-cyanoethanethioamide. Next, the precursors carbothioamides were reacted with different alpha-halocarbonyl compounds and bis(alpha-bromoketones). These reactions afforded the corresponding 4-(substituted)thiazoles and thiazol-4(5H)-ones, in addition to bis(thiazoles), linked to different cores. Additionally, thiazol-4(5H)-ones were condensed with the appropriate bis(aldehydes) to yield the corresponding bis(thiazol-4(5H)-ones), linked to chromene or benzo[f]chromene units via different cores.

Nanoporous colorant sensors and captors for simultaneous recognition and recovery of gold from E-wastes

Platinum group metals have gained significant interest due to their unique characteristics, which make them the main constituents in advanced applications. In this work, we introduce new pH-dependent optical mesocaptors for the colorimetric monitoring and separation of Au(III) from E-waste leach liquors without a preconcentration process. The mesoporous silica nanospheres are fabricated via simple, reproducible, and low-cost procedures. The optical mesocaptor is designed via indirect immobilization of thiazole yellow G (TYG) and amacid yellow M (AYM) chromogenic probes onto mesoporous nanostructured scaffolds. The silanol groups in the mesopores of silica surface robustly anchored dilauryl dimethyl ammonium bromide (DDAB) linker to induce the interactions with the TYG and AYM chelates, thereby leading to the fashioning of a stable optical mesocaptors without releasing of the chelates throughout adsorption and sensing assays. The finding provides evidence of the capability of the synthesized decorated new nanostructured sensor shows excellent sensitivity toward Au(III) with a limit of detection (LOD) as low as 1.16 mu g L-1. Furthermore, the new sensors were able to selectively detect Au(III) in solution with multi ions components. (C) 2020 Elsevier Ltd. All rights reserved.

3-Nitro-2-phenyl-2-trifluoromethyl-2H-chromenes in reactions with azomethine ylides from isatins and (thia)proline: synthesis of spiro[chromeno(thia)pyrrolizidine-11,3′-oxindoles]

1,3-Dipolar cycloaddition of stabilized azomethine ylides generated in situ from isatins and proline to 3-nitro-2-phenyl-2-trifluoromethyl-2H-chromenes in i-PrOH proceeds stereoselectively at room temperature and leads to the formation of hexahydro-6H-spiro[chromeno[3,4-a]-pyrrolizine-11,3′-indolin]-2′-ones with the cis arrangement of the trifluoromethyl group and the nitro group. A similar reaction with the participation of thiaproline-based ylides at 50 degrees C leads to mixtures of diastereomeric tetrahydro-6H,9H-spiro[chromeno[3′,4′:3,4]pyrrolo[1,2-c]thiazole-11,3′-indolin]-2′-ones with a predominance of the cis- or trans-isomer.

Regulation of High-Altitude Hypoxia on the Transcription of CYP450 and UGT1A1 Mediated by PXR and CAR

Little is known about what roles the pregnane X receptor (PXR) and constitutive androstane receptor (CAR) play in drug metabolism in high-altitude hypoxia. Likewise, the potential interaction of nuclear receptors and drug metabolism enzymes during drug metabolism of high-altitude hypoxia is not fully understood. In this work, we investigated the effects of high-altitude hypoxia on transcriptional regulation of cytochrome P450 (CYP450) and UDP-glucuronosyltransferase 1A1 (UGT1A1) genes mediated by PXR and CAR proteins. The protein and mRNA expressions of CYP450, UGT1A1, PXR, and CAR were determined by enzyme-linked immunosorbent assay and qPCR in rats and HepG2 cell lines under hypoxia. Hypoxia potently inhibited the CYP450 isoforms, UGT1A1, PXR, and CAR protein and mRNA expression. To clarify whether PXR and CAR regulate various genes involved in drug metabolism of high-altitude hypoxia, we investigated the expression of CYP1A2, CYP2C9, CYP2E1, CYP3A4, and UGT1A1 using a dual-luciferase reporter assay after treatment with Ketoconazole (KCZ) and Retinoic acid (RA), or silenced PXR and CAR gene expression. In HepG2 cells, hypoxia, KCZ, and RA inhibited CYP450 isoforms and UGT1A1 expression. Activation of PXR and CAR in cells treated with 6-(4-chlorophenyl)-imidazo (2,1-b) thiazole-5-carbaldehyde (CITCO) and rifampicin (Rif) resulted in the enhancement of CYP450 isoforms, UGT1A1, PXR, and CAR. In contrast, this effect was not observed under hypoxia. Taken together, our results suggest that hypoxia inhibits CYP1A2, CYP2C9, CYP2E1, CYP3A4, and UGT1A1 expressionviathe PXR and CAR regulatory pathway.
