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.

N-Radical-Initiated Cyclization through Insertion of Sulfur Dioxide under Photoinduced Catalyst-Free Conditions

A N-radical-initiated cyclization involving the sulfonylation of unactivated alkenes through insertion of sulfur dioxide in the presence of visible light under catalyst-free conditions is accomplished. A range of sulfonated 3,4-dihydro-2H-pyrroles can be generated in good yields under photoinduced sulfonylative conditions. Additionally, the corresponding 2-(3,4-dihydro-2H-pyrrol-2-yl)methylsulfonyl-1-arylethanones can be easily converted to 3,4-dihydro-2H-1,4-thiazine 1,1-dioxides. This photoinduced transformation occurs efficiently at room temperature under catalyst-free conditions, and various functional groups can be tolerated. A tandem radical process is involved through the iminyl radical-mediated cyclization with the insertion of sulfur dioxide; this process shows high efficiency and good selectivity.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 103-47-9. Recommanded Product: N-Cyclohexyltaurine.

A synthesis of functionalized arylthio-acrylates, benzo[b][1,4]thiazines and benzo[4,5]thiazolo[3,2-a]azepines from 2-methylbenzothiazole and acetylenic esters in aqueous media

Alkyl (Z)-3-((2-(N-((E)-3-methoxy-3-oxoprop-1-en-1-yl)acetamido)phenyl)thio)acrylates are obtained from the reaction between 2-methylbenzothiazole and alkyl propiolates in 70% aqueous alcohol, in moderate yields. When dialkyl acetylenedicarboxylates were used under similar conditions, tetra-alkyl 9,10-dihydrobenzo[4,5]thiazolo[3,2-a]azepine-7,8,9,10-tetracarboxylates, together with dialkyl 4-acetyl-3,4-dihydro-2H-benzo[b][1,4]thiazine-2,3-dicarboxylates were obtained in about 4:1 ratios. The stereochemistry of these products has been confirmed by X-ray diffraction.

Sorption of Methylene Blue on Polystyrene/Bentonite Film Composites

The method of mechanochemical dispersion of bentonite in a polystyrene solution was used to modify the polymer and obtain film materials with improved sorption characteristics with respect to the methylene blue (MB) thiazine dye. It is found that the kinetics of the dye sorption are described by the pseudo-first-order equation. The sorption equilibrium is described by the Langmuir isotherm. The values of the limiting sorption capacity and specific surface area of the composite are determined. It is shown that the sorption efficiency of the dye on the PS/bentonite composite increases tenfold as compared with the non-modified sorbent; the extraction rate increases from 10 to 90%. The method of IR spectroscopy is used to show that MB sorption on polystyrene and the PS/bentonite composite is accompanied by electrostatic and donor-acceptor interactions of the reaction sites of MB with the hydroxyl-containing groups of the composite.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2235-54-3 is helpful to your research. COA of Formula: C12H29NO4S.

Antimicrobial Properties of Substituted Quino [3,2-b]benzo[1,4] thiazines

Our previous studies demonstrated that among phenothiazines several derivatives could be found showing strong antiproliferative actions and the property of inhibiting inducible tumor necrosis factor alpha (TNF alpha) production in human blood cultures. The aim of this investigation was to determine potential antimicrobial actions of forty four new phenothiazine derivatives with the quinobenzothiazine structure. The compounds showed differential antibacterial and antifungal activities against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans depending on the compound structures, concentrations and bacterial strains. More specifically, 6-(1-methyl-2-piperidylethyl) quinobenzothiazine displayed strongest actions against S. aureus and E. coli whereas 6-methanesulfonylaminobutyl-9-methylthioquinobenzothiazine exhibited the most universal antimicrobial properties. The correlation between antimicrobial activity and the chemical structure of quinobenzothiazines was discussed.

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.

Pressure-Stabilized Solvates of Xylazine Hydrochloride

High pressure strongly favors the highest-density polymorph Z of active pharmaceutical ingredient 2-(2,6-xylidino)-5,6-dihydro-4H-1,3-thiazine hydrochloride (xylazine hydrochloride, XylHCl) up to about 0.1 GPa only, but still higher pressure destabilizes this structure. Above 0.1 GPa, XylHCl preferentially crystallizes as solvates with CH2Cl2, CHCl3, or (CH3)(2)CHOH depending on the solvent used. However, when XylHCl center dot H2O is dissolved in any of these solvents, the high-pressure crystallizations yield the hydrate XylHCl center dot H2O only. The single crystals of the CH2C12, CHCl3, and (CH3)(2)CHOH solvates could be grown in situ in a diamond anvil cell, which allowed their structure determination from the single-crystal diffraction data. At 0.4 GPa the XylHCl center dot H2O hydrate undergoes a pressure-induced phase transition doubling the unit cell dimensions.

Pressure-Enhanced C-H Bond Activation in Chloromethane Platinum(II) Complexes

The nature of the interaction between chloromethanes CH4-nCln and Pt(II) complexes has been studied by high-pressure X-ray diffraction and infrared spectroscopy in combination with DFT calculations. In case of electron rich complexes such as d(8)-Pt(btz-N,N ‘)(phenyl)L with L = phenyl, Cl, Br and btz = 2,2 ‘-Bi-5,6-dihydro-4H-1,3-thiazine stable chloroform adducts with bridging hydrogen atoms in the eta(1)(C-H)Pt moieties were isolated which display highly activated C-H bonds. This activation is a consequence of a pronounced Pt(d(z2))->sigma*(C-H) back donation and is signaled by large red-shifts of the isolated nu(is)(C-H) stretching modes. The extent of the C-H bond activation and covalent Pt-H bond formation in the eta(1)(C-H)Pt moieties is thereby controlled by (i) the sigma/pi donor capabilities of the ligands L, (ii) the orientation of the coordinating C-H bond with regard to the Pt(d(z2)) orbital and (iii) the applied pressure.
