Luminescence and Nonlinear Optical Properties of Hybrid Associates of Ag2S Quantum Dots with Molecules of Thiazine Dyes

Spectral, kinetic, and nonlinear optical regularities that demonstrate the exchange of electronic excitations between the components of hybrid associates of Ag2S colloid quantum dots (1.7-1.8 nm) in gelatin with molecules of thiazine dyes (Ds) are found. When the IR luminescence of Ag2S quantum dots (QDs) is excited by radiation from the thionine absorption region, its enhancement due to nonradiative resonant energy transfer is observed. The association with methylene-blue molecules blocked the IR luminescence of Ag2S QDs upon its excitation by radiation from the absorption region of the dye due to the transfer of charge carriers. It is demonstrated that the hybrid association of thionine molecules and Ag2S QDs adversely affects the nonlinear optical properties of the latter, which manifests itself in inverse saturated absorption by the action of 10-ns second-harmonic pulses (532 nm) of a Nd3+:YAG laser. For the associates of Ag2S QDs with methylene-blue molecules, the radiation focusing caused by the transfer of charge carriers from the dye and the change in the population of small traps in nanocrystals is found. It is concluded that the direction of the transfer of electronic excitations and the photophysical processes in these objects are determined by the mutual arrangement of the HOMO-LUMO levels of the dye with respect to the levels of dimensional quantization of the Ag2S QDs.

10H-3,6-Diazaphenothiazines triggered the mitochondrial-dependent and cell death receptor-dependent apoptosis pathways and further increased the chemosensitivity of MCF-7 breast cancer cells via inhibition of AKT1 pathways

Breast cancer is one of the leading causes of death in cancer categories, followed by lung, colorectal, and ovarian among the female gender across the world. 10H-3,6-diazaphenothiazine (PTZ) is a thiazine derivative compound that exhibits many pharmacological activities. Herein, we proceed to investigate the pharmacological activities of PTZ toward breast cancer MCF-7 cells as a representative in vitro breast cancer cell model. The PTZ exhibited a proliferation inhibition (IC50 = 0.895 mu M) toward MCF-7 cells. Further, cell cycle analysis illustrated that the S-phase checkpoint was activated to achieve proliferation inhibition. In vitro cytotoxicity test on three normal cell lines (HEK293 normal kidney cells, MCF-10A normal breast cells, and H9C2 normal heart cells) demonstrated that PTZ was more potent toward cancer cells. Increase in the levels of reactive oxygen species results in polarization of mitochondrial membrane potential (Delta psi m), together with suppression of mitochondrial thioredoxin reductase enzymatic activity suggested that PTZ induced oxidative damages toward mitochondria and contributed to improved drug efficacy toward treatment. The (RTPCR)-P-2 Profiler Array (human apoptosis pathways) proved that PTZ induced cell death via mitochondria-dependent and cell death receptor-dependent pathways, through a series of modulation of caspases, and the respective morphology of apoptosis was observed. Mechanistic studies of apoptosis suggested that PTZ inhibited AKT1 pathways resulting in enhanced drug efficacy despite it preventing invasion of cancer cells. These results showed the effectiveness of PTZ in initiation of apoptosis, programmed cell death, toward highly chemoresistant MCF-7 cells, thus suggesting its potential as a chemotherapeutic drug.

The asymmetric unit of the enantiomerically pure title compound, C18H18N2O3S, comprises two independent molecules (A and B) having almost identical conformations. When overlayed, the alignment-r. m. s. deviation value is 0.30 angstrom. The six-membered heterocycle has a twisted half-chair conformation in both molecules. The O atom on the S atom of the ring is pseudo-axial on the thiazine ring and trans to both a phenyl group substituent and the acetamide group in each case. The two benzene rings in each molecule are almost orthogonal to each other, with interplanar dihedral angles of 83.79 (17) and 86.95 (16)degrees. The acetamide group is pseudo-equatorial and a phenyl ring is pseudo-axial on the thiazine ring. Both molecules show a weak intramolecular C-H center dot center dot center dot O interaction between H-atom donors of one of the phenyl rings and the acetamide group. In the crystal, an intermolecular N-H center dot center dot center dot O( thiazine) hydrogen bond links B molecules along the 21 (b) screw axis and, in addition, an N-H center dot center dot center dot O( acetamide) hydrogen bond links A and B molecules across a. A two-dimensional layered structure lying parallel to (001) is generated, also involving weak intermolecular C-H center dot center dot center dot O interactions.

Chaotropic Agents Boosting the Performance of Photoionic Cells

Photoionic cells are a simple and scalable concept for direct solar energy storage, where the redox fuels produced by the photoreaction are separated in different phases to prevent recombination. The presence of chaotropic agents such as urea, that break the structure of water, was found to drastically enhance the quantum yield; a 10-fold increase of quantum yield to over 13% was achieved by addition of chaotropes into a system based on the reductive quenching of Azure B by Co(II)EDTA in water and the extraction of the leuco dye in 1,2-dichloroethane.

Discovery of [1,2,4]Triazole Derivatives as New Metallo-beta-Lactamase Inhibitors

The emergence and spread of metallo-beta-lactamase (MBL)-mediated resistance to beta-lactam antibacterials has already threatened the global public health. A clinically useful MBL inhibitor that can reverse beta-lactam resistance has not been established yet. We here report a series of [1,2,4]triazole derivatives and analogs, which displayed inhibition to the clinically relevant subclass B1 (Verona integron-encoded MBL-2) VIM-2. 3-(4-Bromophenyl)-6,7-dihydro-5H-[1,2,4]triazolo [3,4-b][1,3]thiazine (5l) manifested the most potent inhibition with an IC50 (half-maximal inhibitory concentration) value of 38.36 mu M. Investigations of 5l against other B1 MBLs and the serine beta-lactamases (SBLs) revealed the selectivity to VIM-2. Molecular docking analyses suggested that 5l bound to the VIM-2 active site via the triazole involving zinc coordination and made hydrophobic interactions with the residues Phe61 and Tyr67 on the flexible L1 loop. This work provided new triazole-based MBL inhibitors and may aid efforts to develop new types of inhibitors combating MBL-mediated resistance.

2,1-Benzothiazine 2,2-Dioxides. 5. Hydrolysis of Alkyl 1-R-4-Hydroxy-2,2-Dioxo-1H-2 lambda(6),1-Benzo-Thiazine-3-Carboxylates

Hydrolysis of 1-R-4-hydroxy-2,2-dioxo-1De-2 lambda(6),1-benzothiazine-3-carboxylate esters in HCl-AcOH-H2O mixture at 60A degrees D was accompanied by decarboxylation and led to 1-R-4-oxo-3,4-dihydro-1H-2 lambda(6),1-benzo-thiazine-2,2-diones. In the alkaline medium, regardless of the type of the substituent at position 1, analogous structural transformations occurred at first, but the thiazine ring was also destroyed along with the ester fragment when performing the reaction for a longer time.

DECOLORIZATION KINETICS OF ACID AZO DYE AND BASIC THIAZINE DYE IN AQUEOUS SOLUTION BY UV/H2O2 AND UV/FENTON: EFFECTS OF OPERATIONAL PARAMETERS

The photochemical decolorization of two dyes, namely Acid Yellow 54 and Basic Blue 9, was studied using the UV/H2O2 and UV/Fenton processes. The effects of the amount of H2O2 and FeSO4 as well as the initial pH solution on decolorization kinetics of both the dyes were investigated. The pseudo-first order kinetic model was applied to predict the decolorization of the selected dyes at the different operational conditions and results showed that this model fitted very well with the experimental data. The obtained results also showed the efficiency of UV/Fenton process to quickly degrade aqueous effluents polluted by Acid Yellow 54 and Basic Blue 9 compared to the UV/H2O2 process.

Versatile one-pot synthesis of benzo-fused thiacycles by copper catalysis

A novel, one-pot synthesis of structurally diverse benzo-fused thiacycles via a Cu-catalysed intermolecular C-S coupling/cyclisation tandem process, employing the same catalytic system, has been developed. Thus, 3,4-dihydro-2H-benzo[e][1,3]thiazines and 4H-benzo[e][1,3] thiazines were selectively obtained by this one-pot tandem process from (2-iodophenyl) methanamine and aldehydes or 1-(azido-methyl)-2-iodobenzene, respectively. These reactions proceeded in toluene at 100 degrees C with potassium thioacetate, thiobenzoate or ethyl xanthogenate in moderate to good isolated yields. The first one avoids the imine isolation step. A similar approach to benzo[b] thiophene derivatives from 2-(2- iodophenyl) acetonitrile was also developed.
