Crystal structure, Hirshfeld surface analysis and interaction energy, DFT and antibacterial activity studies of ethyl 2-[(2Z)-2-(2-chlorobenzylidene)-3-oxo-3,4-dihydro-2H-1,4-benzothiazin-4-yl]acetate

The title compound, C19H16ClNO3S, consists of chlorophenyl methylidene and dihydrobenzothiazine units linked to an acetate moiety, where the thiazine ring adopts a screw-boat conformation. In the crystal, two sets of weak C-HPh center dot center dot center dot ODbt (Ph = phenyl and Dbt = dihydrobenzothiazine) hydrogen bonds form layers of molecules parallel to the bc plane. The layers stack along the aaxis direction with intercalation of the ester chains. The crystal studied was a two component twin with a refined BASF of 0.34961 (5). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H center dot center dot center dot H (37.5%), H center dot center dot center dot C/C center dot center dot center dot H (24.6%) and H center dot center dot center dot O/O center dot center dot center dot H (16.7%) interactions. Hydrogen-bonding and van der Waals interactions are the dominant interactions in the crystal packing. Computational chemistry indicates that in the crystal, C-H-Ph center dot center dot center dot O-Dbt hydrogen bond energies are 38.3 and 30.3 kJ mol(-1). Density functional theory (DFT) optimized structures at the B3LYP/ 6-311 G(d,p) level are compared with the experimentally determined molecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap. Moreover, the antibacterial activity of the title compound has been evaluated against gram-positive and gram-negative bacteria.

Alkylation of 5-(3-chlorobenzo[b]thien-2-yl)-1,2,4-triazole-3-thione with Epichlorhydrin and the Role of MW and Solid Support in the Reaction

An efficient eco-friendly approach has been adopted for the selective synthesis of 2,3-epoxypropylsulfanyltriazole 4 from the reaction of 1-chloro-2,3-epoxy-propane (2) with 5-(3-chlorobenzo[b]thien-2-yl)-4H-1,2,4-triazole-3-thione (1) under solvent free microwave conditions in the presence of a solid support. Instead, when the mixture of reactants was irradiated for prolonged time in the absence of solid support, triazolo[2,1-b]thiazine 3 was exclusively afforded in excellent yield. On the other hand, performing the irradiation in the presence of a base, mixtures of compounds 4 and 3 were obtained; the ratio of the two products was dependent on the nature of the base, although 4 was the major product in each case.

The Smiles rearrangement in the syntheses of azaphenothiazines. Part II. The review of the various types of phenyl azinyl and diazinyl sulfides undergoing this rearrangement

Azaphenothiazines are one of the most bioactive heterocyclic scaffolds in medicinal chemistry. This review discusses the Smiles rearrangement of over 40 types of phenyl azinyl sulfides and diazinyl sulfides during syntheses of azaphenothiazines. These syntheses consist of two (rearrangement/cyclization) or three steps (sulfide formation/rearrangement/cyclization) proceeding often rapidly without isolation of intermediates. The rearrangement depends on the nature of sulfides, steric hindrance, reaction conditions (basic, but also weakly and strongly acidic, and even neutral and thermal). Some reaction conditions and catalysts favor direct cyclization. This review arranges the knowledge of the Smiles rearrangement of phenyl azinyl and diazinyl sulfides but also systematizes the syntheses of monoaza-, diaza-, triaza-, tetraazaphenothiazines and their benzo- and dibenzo derivatives. The review shows that some formed azaphenothiazines were wrongly identified and not all wrong structures have been corrected. Some syntheses cannot be defined as proceeding with the rearrangement or not when both the rearranged and direct products are the same. The structure analysis of resulted azaphenothiazines is crucial (the most reliable: X-ray analysis or two-dimensional NMR). The authors hope that this review will prompt researchers to revisit some syntheses of azaphenothiazines. (C) 2020 Elsevier B.V. All rights reserved.

SERS Spectroscopy and DFT Studies of Thionine and its Derivatives Adsorbed on Silver Colloids: Which N Atom is Used for Coordination of a Phenothiazine-Based Natural Dye to Electron-Deficient Metal Surface?

A Surface-enhanced Raman scattering (SERS) investigation has been carried out for thionine and its derivatives, well known blue-based dyes sharing the phenothiazine core. The thionine SERS spectrum is similar to its Raman spectrum. This suggests that the strong Raman bands mostly arising from in-plane ring modes are also enhanced on metal surface. Several originally weak Raman bands arising from the CNC moiety or H atoms on the thiazine N side also largely strengthen in the SERS spectrum. Density functional theory results for the plausible coordinated structures of thionine and the silver adatom reveal that coordination via the thiazine N atom to Ag+ leads to the most stable structure, and its calculated spectrum also best reproduces the SERS spectrum. The thionine derivatives show surprisingly analogous spectra, reflecting that the derivatives coordinate in a similar fashion to the metal surface. The high preference of the thiazine N atom for coordination is traced to the positive charge on the S atom.

Characterization and photocatalytic performance evaluation of various metal ion-doped microstructured TiO2 under UV and visible light

Commercially available microcrystalline TiO2 was doped with silver, ferrous and ferric ion (1.0mol %) using silver nitrate, ferrous sulfate and ferric nitrate solutions following the liquid impregnation technology. The catalysts prepared were characterised by FESEM, XRD, FTIR, DRS, particle size and micropore analysis. The photocatalytic activity of the prepared catalysts was tested on the degradation of two model dyes, methylene blue (3,7-bis (Dimethylamino)-phenothiazin-5-ium chloride, a cationic thiazine dye) and methyl blue (disodium;4-[4-[[4-(4-sulfonatoanilino)phenyl]-[4-(4-sulfonatophenyl)azaniumylidenecyclohexa-2,5-dien-1-ylidene]methyl]anilino]benzene sulfonate, an anionic triphenyl methane dye) under irradiation by UV and visible light in a batch reactor. The efficiency of the photocatalysts under UV and visible light was compared to ascertain the light range for effective utilization. The catalysts were found to have the anatase crystalline structure and their particle size is in a range of 140-250nm. In the case of Fe2+ doped TiO2 and Fe3+ doped TiO2, there was a greater shift in the optical absorption towards the visible range. Under UV light, Ag+ doped TiO2 was the most efficient catalyst and the corresponding decolorization was more than 99% for both the dyes. Under visible light, Fe3+ doped TiO2 was the most efficient photocatalyst with more than 96% and 90% decolorization for methylene blue and methyl blue, respectively. The kinetics of the reaction under both UV and visible light was investigated using the Langmuir-Hinshelwood pseudo-first-order kinetic model. Kinetic measurements confirmed that, Ag+ doped TiO2 was most efficient in the UV range, while Fe3+ doped TiO2 was most efficient in the visible range.

An Anti-Inflammatory Azaphenothiazine Inhibits Interferon beta Expression and CXCL10 Production in KERTr Cells

An azaphenothiazine derivative, 6-chloroethylureidoethyldiquino[3,2-b; 2 0,3 0 -e][1,4]thiazine (DQT), has recently been shown to exhibit immunosuppressive activities in mouse models. It also inhibited the expression of CXCL10 at the protein level, at non-toxic concentrations, in the culture of KERTr cells treated with double-stranded RNA, poly(I:C). In this report, we demonstrated that DQT inhibits the transcription of the CXCL10 gene. Although CXCL10 is an IFN gamma-inducible protein, we found that the CXCL10 protein was induced without the detectable release of IFN gamma or I kappa B degradation. Hence, we concluded that IFN gamma or NF kappa B was not involved in the regulation of the CXCL10 gene in KERTr cells transfected with poly(I: C), nor in the inhibitory activity of DQT. On the other hand, we found that IFN beta was induced under the same conditions and that its expression was inhibited by DQT. Kinetic analysis showed that an increase in IFN beta concentrations occurred 4-8 h after poly(I: C) treatment, while the concentration of CXCL10 was undetectable at that time and started to increase later, when IFN beta reached high levels. Therefore, DQT may be regarded as a new promising inhibitor of IFN beta expression and IFN beta-dependent downstream genes and proteins, e.g., CXCL10 chemokine, which is implicated in the pathogenesis of autoimmune diseases.

New Schiff base ligand was prepared by condensation of 5-acetyl-4-hydroxy-2H-1,3-thiazine-2,6(3H)-dione with o-phenylenediamine. Cu(II), Ni(II), Co(II), VO(IV), Zn(II), Cd(II) and UO2(VI) complexes were prepared and characterized on the basis of elemental analyses, IR, (H-1 and C-13) NMR, electronic, ESR and mass spectra; magnetic, molar conductance measurements as well as thermal gravimetric analysis. The coordination sites of the Schiff base ligand are phenolic oxygen, azomethine nitrogen and amino group nitrogen; where the ligand acts as monobasic tridentate. All results established that all compounds have 1:1 (metal: ligand) stoichiometry except Ni(II)- and VO(IV)- complexes have 1:2 (metal: ligand) stoichiometry. The metal complexes showed octahedral geometry except Cu(II) complex which showed square planar arrangement and UO2(VI) has pentagonal bipyramidal arrangement. Thermodynamic parameters were calculated for the ligand and its metal complexes using Coats-Redfern method. The ligand and its complexes were tested in vitro bioassays against some Gram-negative and Gram-positive bacteria and the fungus strain; showing good results for some of these compounds. The antitumor activity of the ligand and its copper(II) and oxovanadium(IV) complexes was investigated against HepG2 cell line. Density Function Theory (DFT) level implemented in the Gaussian 09 program was used to optimize structure and some structural parameters of the ligand and its metal complexes such as: total energy, HOMO, LUMO as well as dipole moment. The computed data were correlated with the experimental results. (C) 2019 Elsevier B.V. All rights reserved.
