Spectral and kinetic features of nonradiative energy transfer in hybrid associates of colloidal quantum dots and organic dyes

The features of nonradiative resonance energy transfer in hybrid associates of colloidal CdS quantum dots (QDs) with molecules of a thiazine dye and J-aggregates of a carbocyanine dye are discussed. The case of an inhomogeneously broadened recombination band of donor (CdS QDs) luminescence is considered. We detected spectral-selective quenching of recombination luminescence of colloidal CdS QDs in association with organic dyes. The maximum of quenching occurs in the region of absorption of the acceptor (organic dye molecule). It is shown using the time-correlated single photon counting technique that the lifetime of the QD luminescence decreases synchronously with the quenching of the luminescence, but only at the wavelengths falling in the region of absorption of the dye. Based on the concept of a donor-acceptor nature of emission of CdS QDs, the dependence of the efficiency of nonradiative energy transfer on the luminescence wavelength is analyzed taking into account the Poisson distribution of its quenchers.

SYNTHESIS OF SOME NOVEL THIAZOLE, THIADIAZOLE AND 1,4-PHENYLENE-BIS-THIAZOLE DERIVATIVES AS POTENT ANTITUMOR AGENTS

A novel series of 2-ethylidenehydrazono-5-arylazothiazoles 5a-h and 2-ethylidenehydrazono-5-arylazothiazolones 9a-d were prepared by cyclocondensation of hydrazonyl halides 3a-h and 7a-d with ethylidenethiosemicarbazide 2. In addition, reaction of 2 with N-phenyl-carbohydrazonyl chloride (14), afforded 1,3,4-thiadiazole derivative 17 as the end product. Moreover, the thiosemicarbazide derivative 2 was reacted with various bromoacetyl compounds 19a-d and 1,1′-(1,4-phenylene)bis(2-bromoethanone) (21) furnished the respective thiazole derivatives 20a-d and 1,4-phenylene-bis-thiazole derivative 22. The structures of the newly synthesized compounds were established on the basis of spectroscopic evidences and their alternative syntheses. The newly synthesized compounds were evaluated for their antitumor activities against hepatocellular carcinoma (HepG2) cell line and the results revealed promising activities of compounds 5h, 5d, 5g, 5f and 5e with IC50 equal 2.23 +/- 0.28, 2.48 +/- 0.34, 2.49 +/- 0.24, 4.03 +/- 0.11, and 5.32 +/- 0.27 mu M, respectively.

Decolorization of heterocycle dye Neutral Red by white-rot fungus Perenniporia subacida

A white-rot fungus Perenniporia subacida was developed for decolorizing twelve structurally various dyes from anthraquinone, azo, heterocycle, thiazine, and triphenylmethane groups. Among them, heterocycle dye Neutral Red with preferable decolorization performance was selected for further experiments and this strain could be utilized sequentially for three consecutive cycles with declining decolorization (%). After a 10-day incubation period, higher dye uptake (96.56%) was obtained at constant inoculum and agitation speed with the optimum physicochemical parameters like initial pH at 4.0, temperature at 35 degrees C, initial dye concentration at 100 mg/L, and ionic strength at 0.1 mol/L. Noteworthy induction of various dye decolorizing enzymes viz. lignin peroxidase, laccase, manganese peroxidase, tyrosinase, and nicotinamide-adenine dinucleotide hydrogen-2,6-dichlorophenol indophenol reductase compared to control, point out toward their involvement in overall decolorization and degradation process. Analytical studies like fourier transform infrared spectroscopy and gas chromatography-mass spectroscopy were used to identify the degraded metabolites and scrutinize the degradation process. Phytotoxicity studies indicated that the fungal treatment favors detoxification of dye Neutral Red. It is suggested that P. subacida has great potential for decolorizing heterocycle dyes.

Synthesis, Characterization and Molecular Docking of Novel Bioactive Thiazolyl-Thiazole Derivatives as Promising Cytotoxic Antitumor Drug

Reactions of ethylidenethiocarbohydrazide with hydrazonoyl halides gave 1,3-thiazole or 1,3,4-thiadiazole derivatives according to the type of hydrazonoyl halides. Treatment of ethylidenethiosemicarbazide with hydrazonoyl halides and dimethylacetylene dicarboxylate (DMAD) afforded the corresponding arylazothiazoles and 1,3-thiazolidin-4-one derivatives, respectively. The structures of the synthesized products were confirmed by IR, H-1-NMR, C-13-NMR and mass spectral techniques. The cytotoxic activity of the selected products against the Hepatic carcinoma cell line (Hepg-2) was determined by MTT assay indicating a concentration dependent cellular growth inhibitory effect, especially for compounds 14c and 14e. The dose response curves indicated the IC50 (the concentration of test compounds required to kill 50% of cell population) were 0.54 M and 0.50 M, respectively. Confocal laser scanning imaging of the treated cells stained by Rhodamin 123 and Acridine orange dyes confirmed that the selected compounds inhibit the mitochondrial lactate dehydrogenase enzymes. The binding mode of the active compounds was interpreted by a molecular docking study. The obtained results revealed promising cytotoxic activity.

Therapeutic effects of an azaphenothiazine derivative in mouse experimental colitis

Phenothiazines represent a class of compounds of potential therapeutic utility. In this report we evaluated therapeutic value of an azaphenothiazine derivative, 6-acetylaminobutyl-9-chloroquino[3,2-b]benzo[1,4]thiazine (QBT), given intragastrically, in the model of dextran sodium sulfate-induced colitis in C57BL/6 mice using 5-aminosalicylic acid (5-ASA) as a reference drug. Colitis symptoms such as body weight loss, diarrhea and hematochezia (blood in stool) were observed and registered and disease activity index (DAI) was calculated. In addition, weight and cell numbers in the lymphatic organs and histological parameters of the colon wall were analyzed. The effects of QBT on viability of colon epithelial cell lines were also determined. We showed that weight and cell number of draining mesenteric lymph nodes were lower in mice treated with QBT in comparison to their control counterparts. The number of thymocytes, drastically reduced in control mice, was elevated in mice treated with the compounds with a significant effect of 5-ASA. In addition, an abnormal composition of blood cell types was partially corrected in these groups. Histological analysis of the colon revealed that the pathological changes were partially normalized by QBT and even to a higher degree by 5-ASA. In conclusion we demonstrated a therapeutic efficacy of the compound in amelioration of local and systemic pathological changes associated with chemically-induced colitis in mice. A possible mechanism of action of the compound is discussed.

Isolation of bacterial strains able to metabolize lignin and lignin-related compounds

In this study, we identified five strains isolated from soil and sediments able to degrade kraft lignin, aromatic dyes and lignin derivatives. Using 16S rRNA gene sequencing, the isolates were identified as Serratia sp. JHT01, Serratia liquefacien PT01, Pseudomonas chlororaphis PT02, Stenotrophomonas maltophilia PT03 and Mesorhizobium sp. PT04. All the isolates showed significant growth on lignin with no water-extractable compounds. Synthetic aromatic dyes were used to assess the presence of oxidative enzymes. All the isolates were able to use the thiazine dye Methylene blue and the anthraquinone dye Remazol Brilliant Blue R as the sole carbon source. Guaiacol, veratryl alcohol and biphenyl were also mineralized by all the strains isolated. These results suggest they could be used for the treatment of aromatic pollutants and for the degradation of the lignocellulosic biomass. Significance and Impact of the StudyThe valorization of waste lignin and lignocellulosic biomass by biocatalysis opens up new possibilities for the production of value-added substituted aromatics, biofuel and for the treatment of aromatic pollutants. Bacteria with ligninolytic potential could be a source of novel enzymes for controlled lignin depolymerization. In this work, five soil bacteria were isolated and studied. Every isolate showed significant growth on lignin and was able to degrade several lignin monomers and ligninolytic indicator dyes. They could thus be a source of novel ligninolytic enzymes as well as candidates for a bacterial consortium for the delignification of lignocellulosic biomass.

Determination of Lipophilicity of Allyl Thiosemicarbazide, N-1-Thiocarbamylamidrazone Derivatives, and their Cyclic Products by RP-HPLC, RP-TLC, and Theoretical Methods: Effects of Selected Compounds on the CNS of Mice

The allyl thiosemicarbazide, N-1-thiocarbamylamidrazone derivatives, and the products of their cyclization: the 1,2,4-triazole, 1,3,4-thiadiazole, 1,2,4-triazole[3,4-b]1,3-thiazine, 1,2,4-triazole[3,2-b]1,3-thiazine, 1,3,4-thiadiazole[3,2-a]pyrimidine, 5,6-dihydrothiazolo[2,3-c][1,2,4]triazole, and benzoic acid derivatives have been analyzed by RP-HPLC and RP-TLC methods using the methanol-water mixtures as the mobile phase and the octadecyl stationary phase. The lipophilicity was expressed as the chromatographically derived descriptors: mean of k(mk), mean of logk (mlogk), logk(W), S, and phi(0), scores of k, logk, and R-M corresponding to the first principal component. Additionally, the authors propose to introduce a descriptor (logk(m)) corresponding to the residual specific interactions. Chromatographic parameters of lipophilicity were compared with the partition coefficient (logP) calculated by various softwares (milogP, clogP, AlogPs, AClogP, AlogP, MlogP, KOWWIN, XlogP2, XlogP3). The matrices were created with logk(W) or R-MW and logP and they have been the subject of PCA analysis. The effects of the selected compounds on the central nervous system (CNS) of mice were studied.

N-alkylphenothiazines – synthesis, structure and application as ligands in metal complexes

Phenothiazines are a large group of heterocyclic, aromatic molecules with nitrogen and sulphur between two benzene rings. Their derivatives, N-alkylphenothiazines have substituent on heterocyclic nitrogen atom which gives them different properties. Also, a series of these molecules have substitution on carbon atom at place 2 of phenothiazine benzene ring. Alkylphenothiazines contain aminoalkyl substituent and their alkyl, acyl and sulphonil derivatives, as well as monocyclic and bicyclic heterocycles attached at thiazine nitrogen atom or directly linked to benzene ring. The N-alkylphenothiazines have been known as antipsychotic drugs, but they also possess antibacterial, antifungal, anticancer activity, and ability to react with macromolecules and to coordinate to the metals. Metal complexes with N-alkylphenothiazines are biological active compounds with different antimicrobial activities and cytotoxic effect against tumor cell lines. The large field of application of N-alkylphenothiazines is very attractive in terms of synthesis of new related derivatives, metal complexes, studying their properties and applications. This article presents a review of the literature and a contemporary view at N-alkylphenothiazines – their synthesis and application, as well as their metal complexes which have promising biological effects.

A New Sustainable Strategy for Synthesis of Novel Series of Bis-imidazole and Bis-1,3-thiazine Derivatives

An expeditious, eco-friendly, and efficacious protocol was achieved for the preparation of bis-imidazoles and bis-1,3-thiazines from the reaction of tetracyanoethylene with dialdehydes or bis-thiosemicarbazones, respectively. Merely mixing and sonicating the starting materials furnishes the desirable products in considerable yields. This reaction smoothly proceeded and presented many merits, over conventional and mechanochemical approaches, including simple experimental workup procedure, no by-products, and short reaction time. Moreover, the protocol scoring admirably in various green metrics, as a consequence, shows these approaches to be an ideal sustainable and green process.
