Radical cation and dication of a 4H-dithieno[2,3-b:3′,2′-e][1,4]-thiazine

A p-tert-butylphenyl substituted 4H-dithieno[2,3-b: 3′,2′-e][1,4] thiazine was synthesized by twofold Buchwald-Hartwig coupling. The electronic properties (UV/Vis, cyclic voltammetry and spectroelectrochemistry) and the DFT-and TD DFT-calculated electronic structure reveal that the parent system and the radical cation and dication oxidation products are highly polarizable p-systems with strong charge transfer contributions. The radical cation and the dication were prepared by oxidation with antimony(V) pentachloride, giving stable deeply colored salts. EPR spectroscopy of the radical cation furnishes hyperfine coupling constants with the nitrogen nucleus and the alpha-thienyl protons. The dication is EPR silent and was structurally characterized by recording an NMR spectrum.

A comparative study of media polarity effects on the linear and third-order nonlinear optical responses of thiazine dyes

In this paper, solvent effects on the linear and nonlinear optical responses of thiazine dyes were investigated. Spectroscopic and open aperture Z-scan techniques were used for studying linear and nonlinear responses of azure A and methylene blue dyes. The experimental results show that linear and nonlinear optical properties of used dyes depend highly on the molecular structure and their surrounding media characteristics. The calculated contribution of various media-induced interactions indicate that solvent hydrogen bond acceptor and solvent dipolarity and polarizability abilities have significant effects on the linear and nonlinear absorption characteristics of thiazine dyes. Moreover, by transition of the linear optics domain to nonlinear optics, similar resonance structures were obtained for thiazine dyes. So, the spectroscopic technique can be considered as a simple method for prediction of dominant resonance structures and effective solvent polarity parameters on the third-order nonlinear properties of azure A and methylene blue dyes.

The ant Lasius niger is a new source of bacterial enzymes with biotechnological potential for bleaching dye

Industrial synthetic dyes cause health and environmental problems. This work describes the isolation of 84 bacterial strains from the midgut of the Lasius niger ant and the evaluation of their potential application in dye bioremediation. Strains were identified and classified as judged by rRNA 16S. The most abundant isolates were found to belong to Actinobacteria (49%) and Firmicutes (47.2%). We analyzed the content in laccase, azoreductase and peroxidase activities and their ability to degrade three known dyes (azo, thiazine and anthraquinone) with different chemical structures. Strain Ln26 (identified as Brevibacterium permense) strongly decolorized the three dyes tested at different conditions. Strain Ln78 (Streptomyces ambofaciens) exhibited a high level of activity in the presence of Toluidine Blue (TB). It was determined that 8.5 was the optimal pH for these two strains, the optimal temperature conditions ranged between 22 and 37 degrees C, and acidic pHs and temperatures around 50 degrees C caused enzyme inactivation. Finally, the genome of the most promising candidate (Ln26, approximately 4.2 Mb in size) was sequenced. Genes coding for two DyP-type peroxidases, one laccase and one azoreductase were identified and account for the ability of this strain to effectively oxidize a variety of dyes with different chemical structures.

The Relationship between NO-Synthase Inhibitory Activity of N,S-Containing Heterocycles and Their Radioprotective and Antileukemic Properties

The effect of NO-synthase (NOS) activator and inhibitors on leukemic cell lines HL-60, K-562, and MOLT-4 and bone marrow cells of untreated patients diagnosed with B-cell acute lymphoblastic leukemia compared with lymphocytes from healthy donors is examined. The obtained data on the relationships between the radioprotective, NOS inhibitory, and cytotoxic properties of a number of thiazine, thiazoline, and thiourea derivatives indicates their potential for use as agents for complex radio- and chemotherapy.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 147118-35-2. Formula: C31H39O4PSi.

One-pot synthesis of highly functionalized benzo [1,3] thiazine from isocyanides, aniline, and heterocumulene via Cu-catalyzed intramolecular C-H activation reactions

A one-pot synthesis of functionalized benzo thiazine derivatives via a Cu-catalyzed, multicomponent reaction of isocyanides, aniline, and heterocumulenes in acetonitrile at room temperature was developed. Transition metal-catalyzed activation of C-H bonds under mild copper-catalytic reaction conditions, using simple and available starting materials, also obtaining a pure product with high yield without applying column chromatography are the major advantages of the applied method among the other ones used for this purpose. The structures are confirmed spectroscopically (H-1- and C-13-NMR, IR, and EI-MS) and through elemental analyses.

An alternative approach to the synthesis of a series of new pyrimido[5′,4’:5,6][1,4]thiazino[2,3-b] quinoxaline derivatives is described. Reaction of 5-bromo-2,4-dichloro-6-methylpyrimidine and 3-aminoquinoxaline-2-thiol leads to the key intermediate 3-[(5-bromo-2-chloro-6-methylpyrimidin-4-yl)thio]quinoxalin-2-amine. This intermediate can be transformed into the title ring systems by subsequent treatment either with secondary amines followed by intramolecular cyclisation or initial intramolecular cyclisation with subsequent reaction with secondary amines.

Recyclization of diethoxymethyl substituted benzimidazo-fused thiazolium salts

3-Diethoxymethyl-3-hydroxy-3,9-dihydro-2H-benz[4,5]imidazo[2,1-b]thiazol-4-ium salts were synthesized by reaction of chloro oxiranes or isomeric alpha-chloro ketones with 2-mercaptobenzimidazole. The acetal group of the aforementioned salts undergoes hydrolysis in acidic medium to liberate aldehyde which would react with the NH-moiety of mercaptobenzimidazole, thus leading to cycle expansion with the formation of 3,3,4-trihydroxy-3,4-dihydro-2H-benz[4,5]imidazo[2,1-b][1,3]thiazinium salts. In DMSO solution, the 3,3,4-trihydroxythiazine moiety of the latter compounds is oxidized into 3,4-dioxothiazine one existing in enol form.
