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.

Crystal structure of Brinzolamide: a carbonic anhydrase inhibitor

In crystal structure of the title compound, C12H21N3O5S3 [systematic name: (R)-4-ethylamino-2-(3-methoxypropyl)-3,4-dihydro-2H-thieno[3,2-e][1,2]thiazine-6-sulfonamide 1,1-dioxide], there exist three kinds of hydrogen-bonding interactions. The sulfonamide group is involved in hydrogen bonding with the secondary amine and the methoxy O atom, resulting in the formation of layers parallel to the bc plane. The layers are linked by an N-H center dot center dot center dot O hydrogen bond involving a sulfonamide O atom as acceptor and the secondary amine H atom as donor, which gives rise to the formation of a unique bilayer structure. The absolute structure of the molecule in the crystal was determined by resonant scattering [Flack parameter = 0.01 (4)].

Adsorptive removal of thiazine dyes from aqueous solutions by oil shale and its oil processing residues: Characterization, equilibrium, kinetics and modeling studies

Adsorption characteristics of oil shale (OS) and its pyrolysis byproducts for cationic thiazine dyes were investigated using thionine (TH), toluidine blue (TB) and methylene blue (MB). The time dependent data for the OS adsorption were analyzed using the linear driving force (LDF) model by combining with the Langmuir isotherm. The external mass transfer (k(f)) and surface diffusion (D-s) coefficients were analytically calculated based on McKay equation. They decreased with increasing molecular sizes of the dyes in the following order TH > TB > MB. In contrary, desorption efficiency in 0.1 M NaCI solution increased in the same order. The thermogravimetric analysis (TGA/DTG), atomic force microscopy (AFM), diffuse reflectance infrared Fourier transforms (DRIFT) and X-ray diffraction (XRD) spectroscopy techniques were used in conjunction to characterize the OS samples. A comparison of (DRIFT) spectra of the dye loaded and unloaded adsorbents showed that the larger dye molecules are primarily adsorbed on the negatively charged surface hydroxyl groups and/or on organic functional groups with electrostatic interactions while the smaller molecules replace with structural cations in the interlayer space of the mineral matrices. Adsorption capacity of the pyrolysis residue obtained in nitrogen atmosphere at 200 degrees C (OS-200) for the dyes decreased with respect to the OS whereas the byproduct at 500 degrees C (OS-500) had considerably higher adsorption ability. All of the dyes were completely removed by the OS and OS-500 from dilute solutions (<0.5 mmol L-1). The OS-500 was also a good candidate for water remediation due to its high dye removal capacity in concentrated dye solutions. (C) 2015 Elsevier B.V. All rights reserved.

Synthesis of 2,5-Disubstituted Derivatives of Pyrano[2,3-d][1,3]thiazines via the Interaction of 2-Substituted 4-Hydroxy-6H-1,3-thiazine-6-ones with Aldehydes

A new and efficient route for the synthesis of derivatives of the poorly investigated pyrano[2,3-d][1,3]thiazine heterocyclic system is disclosed. These compounds were prepared via annulation of 2-aryl-4-hydroxy-6H-1,3-thiazine-6-ones with aliphatic and aromatic aldehydes in the presence of pyridine. The method is general and versatile, and the interaction is independent on the nature of the aldehyde, the only exceptions being formaldehyde and salicylaldehydes.

Removal behaviour of a thiazine, an azo and a triarylmethane dyes from polluted kaolinitic soil using electrokinetic remediation technology

In this study, we investigated the potentiality of the electro-kinetic remediation (EKR) technique for the removal of organic dyes polluted soil. Methylene blue (MB), methyl orange (MO), and phenol red (PR) are representing a thiazine, an azo, and a tryarilmethane dye respectively, which was spiked with kaolinite were selected as a model for pollutant dyes tests. An EKR tool (15 cm length) equipped with a DC electric current with the maximum values of 30 V. Graphite electrodes were used for both anode and cathode was set up for two weeks operation. As a result, only 40-55 % of dye was removed from the soil sections by using distilled water. However, by the addition of some electrolytes; the percentage of dyes removed from the soil increased from 73-76 % and 85-89 % for sodium sulphate, and monosodium dihydrogen phosphate, respectively. It resulted that 55-64 % of dyes was removed without controlling the pH. The significant improvement was achieved by controlling the pH of the system. By controlling the pH in the cathode chamber, only 23 % of MB, 25 % of MO, and 18 % of PR dyes remain in the soil sections, respectively. While by controlling the pH in the anode chamber, almost 90 % of tested dyes could be removed from the kaolinite chamber effectively. The movement of a thiazine dye, from the anode to the cathode chamber was controlled by electro-migration and electro-osmosis phenomena. An azo dye transported from the cathode to the anode chamber by a similar process. However, a triarylmethane dye was removed from the soil sections by only electro-osmosis process. For three kinds of tested dyes, it were found that electro-osmotic flow moving from the anode to the cathode directions. The ageing of dye affects the removal percentage of the dye.

Azaphenothiazines – promising phenothiazine derivatives. An insight into nomenclature, synthesis, structure elucidation and biological properties

For the last two decades, classical phenothiazines have attracted attention of researchers, as the hitherto investigations have revealed many significant biological activities within this class of compounds, other than originally discovered neuroleptic ones. Important, new pharmaceutical results on phenothiazines, as 10-substituted dibenzothiazines, were recently highlighted in several reviews. Azaphenothiazines are structurally modified phenothiazines by substitution of one or both benzene rings in the phenothiazine ring system with the azine rings, such as: pyridine, pyridazine, pyrimidine, pyrazine, 1,2,4-triazine, quinoline, quinoxaline, benzoxazine and benzothiazine. They form over 50 different heterocyclic systems, of tri-, tetra-, penta- and hexacyclic structures, and contain from one to even four azine nitrogen atoms. This review summarizes the methodical knowledge on azaphenothiazines, referring to their nomenclature, synthesis, structure analysis and above all significant varied biological activities, examined in vitro and in vivo. It describes, in addition, current trends in the synthesis of azaphenothiazines. The influence of the azaphenothiazine ring system, the nature of the substituents, predominantly at the thiazine nitrogen atom, as well as at the azine nitrogen atom and carbon atom, on the biological activities, were also discussed.

The Metabolism of Methylene Blue and Its Derivatives in Japanese Eel (Anguilla Japonica)

Methylene blue (MB) is commonly used in aquaculture as a fungicide and antidotes. This study was designed to explore the pharmacokinetics of MB in Japanese eel (Anguilla Japonica) immersed in 10 mg L-1 and 20 mg L-1 MB for 0.5 h. The concentrations of MB and its derivatives in the blood, liver, kidney, skin and muscle were determined by HPLC after immersion. The results showed that the changes of drug concentrations in Japanese eel were basically the same in different dose groups, showing a general trend of increasing at first and then decreasing, but the peak time was slightly different. The peak concentration of the drug was positively correlated with the dose level. The peak concentrations of MB in MB (20 mg L-1) group, MB, azure A and azure B in the tissues of Japanese eel were significantly higher than those in MB (10 mg L-1) group. Moreover, MB, azure A and azure B remained for a long time and could still be detected at 64 days, and azure C was not detected in tissues.
