Stereoselective synthesis of 4-aminobenzo[c][1,2] thiazine via modification of the Harmata benzothiazine synthesis

A stereoselective synthesis of 4-aminobenzothiazines was developed through a modified Harmata benzothiazine synthesis. The reaction has very good substrate scope and good functional group tolerance was observed. The products were obtained with high enantiomeric purity. Many interesting heterocyclic analogues were made using this methodology.

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 10297-73-1. COA of Formula: https://www.ambeed.com/products/10297-73-1.html.

Protonation-State-Driven Photophysics in Phenothiazinium Dyes: Intersystem Crossing and Singlet-Oxygen Production

The impact of altering the solvent pH value on the photodynamic activity of thionine has been studied computationally by means of density functional theory and multi-reference interaction methods. To this end, we have investigated the electronic structure of the ground and excited states of diprotonated (TH22+) and neutral imine (T) forms of thionine (TH+). It is well known experimentally that the T-1 state of TH+ undergoes acid-base equilibrium reactions resulting in a pronounced pH effect for the efficiency of singlet-oxygen (O-1(2)) production. Our results show that the energy-transfer reactions from the T-1 state of TH22+ and T to O-3(2) correspond to reversible equilibrium processes, whereas in TH+ this process is very exothermic in a vacuum (-0.66 eV) and in aqueous solution (-0.49 eV). These facts explain the experimental observation of a much smaller efficiency of O-1(2) production for TH22+ than for TH+. Moreover, we found that the pH value significantly effected the intersystem crossing (ISC) kinetics impacting the concentration of triplet-state species available for energy transfer. In very acidic aqueous solution (pH < 2) where TH22+ is the prevailing species, the ISC proceeds with a rate constant of approximate to 10(8) s(-1). In a basic medium where T is the dominant species, ISC decay occurs by means of a thermally activated channel (approximate to 10(8)s(-1)) which competes with fluorescence (5.32 x 10(7) s(-1)). According to these results, maximum ISC efficiency is expected for intermediate acidic pH values (TH+, approximate to 10(9) s(-1)). Synthetic Route of 10297-73-1, One of the oldest and most widely used commercial enzyme inhibitors is aspirin, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 10297-73-1.

Synthesis, spectroscopic structure identification, X-ray study and anticancer activities of new angularly fused quinobenzothiazines

Synthesis of 16 new tetracyclic angularly fused azaphenothiazines, 8-, 9- and 10-substituted quinobenzo1,4-thiazines (benzo[a]-3-azaphenothiazines) was based on the reactions of dichlorodiquinolinyl disulfide and diquinodithiin with substituted anilines. Whereas the reactions with p-fiuoroaniline and p-methylthioaniline led to only one product, the reaction with m-triflouromethylaniline led to isomeric compounds. The obtained 8-10-substituted 12H-quinobenzothiazines were further transformed into 12 substituted derivatives through allcylation of the thiazine nitrogen atom. The structure analysis was based on 1D and 2D NMR (NOESY, COSY, HSQC and HMBC) spectra which enabled to distinguish the isomers and to exclude retro-Smiles rearrangement and the azine nitrogen atom alkylation pathways. This supposition was fully confirmed by X-ray analysis showing the quinobenzothiazine system to be folded and the substituent at the thiazine nitrogen atom in an equatorial position. Some compounds exhibited anticancer activity against MCF-7, MDA-MB-231 and SNB-19 cell lines similar to a reference drug cisplatin. The structure-activity relationship of the compounds were discussed. (C) 2016 Elsevier B.V. All rights reserved.

Methylammonium iodo bismuthate perovskite (CH3NH3)(3)Bi2I9 as new effective visible light-responsive photocatalyst for degradation of environment pollutants

In this work, the photocatalytic activity of a new visible light-responsive (CIH3NH3)(3)Bi2I9 hybrid organic-inorganic perovskite (HOIP) was addressed for the very first time in the treatment of aqueous solutions of model organic dyes. The photocatalyst was successfully prepared by a low temperature solvo-termal method, easily reproducible. The catalyst was characterized by Fourier-transform infrared spectroscopy (FP-IR), X-ray diffraction spectrometer (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDS), X-ray photoelectron spectroscopy (XPS) techniques and UV diffuse reflectance spectrum. The efficiency of photocatalyst was tested for the removal of different type of dyes: fluorone dye (rhodamine B), thiazine dye (methylene blue) and azo dye (reactive Blue 4). Moreover, a multi-contaminated solution, with methylene blue and crystal violet (triarylmethane dye), was used to simulate a real industrial wastewater effluent. The results highlighted an increase of the photocatalytic activity respect the pristine precursor, bismuth iodide. The experiments showed that the values of removal was higher for rhodamine B respect the other dyes, with a removal of 98% after three hours under visible light irradiation. The efficiency of the photocatalyst was also confirmed under optimal conditions with high pressure liquid chromatography (HPLC). The gradual disappearance of rhodamine B peak accompanied by the appearance of by-products peaks was investigated. The stability of the photocatalyst was tested for three consecutive re-cycles. Analysis on different visible light sources was performed: halogen provided higher efficiency respect LED lamp. The outcomes of the present work aim to open the possibility of considering HOIP as a new potential photocatalyst for contaminants treatment.

Unexpected Products from Mesoionic 1,3-Thiazinium and Oxazinium Olates: A Novel Access to 3,5-Diaryl-1,3-thiazine-2,4,6-trione and Alkoxy-3,5-diphenyl-3H-1,3-oxazine-2,6-dione Derivatives

The condensation of (chlorocarbonyl)ketenes 1 with N-phenylthiocarbamates 2 and N-phenylcarbamates 6 is postulated to lead to the formation of unstable mesoionic 1,3-thiazinium 4-olates I or 1,3-oxazinium 4-olates II, respectively. At room temperature, appropriately substituted mesoionic 1,3-thiazinium 4-olates I eliminated the corresponding alkene with generation of 3,5-diaryl-1,3-thiazine-2,4,6-trione derivatives 3. However, the methoxy-substituted compound 5 was stable at room temperature at least for several weeks. In the case of the mesoionic1,3-oxazinium 4-olates II an alkyl group migration affords 4-alkoxy-3,5-diphenyl-3H-1,3-oxazine-2,6-diones 7.

An Anti-Inflammatory Azaphenothiazine Inhibits Interferon beta Expression and CXCL10 Production in KERTr Cells

An azaphenothiazine derivative, 6-chloroethylureidoethyldiquino[3,2-b; 2 0,3 0 -e][1,4]thiazine (DQT), has recently been shown to exhibit immunosuppressive activities in mouse models. It also inhibited the expression of CXCL10 at the protein level, at non-toxic concentrations, in the culture of KERTr cells treated with double-stranded RNA, poly(I:C). In this report, we demonstrated that DQT inhibits the transcription of the CXCL10 gene. Although CXCL10 is an IFN gamma-inducible protein, we found that the CXCL10 protein was induced without the detectable release of IFN gamma or I kappa B degradation. Hence, we concluded that IFN gamma or NF kappa B was not involved in the regulation of the CXCL10 gene in KERTr cells transfected with poly(I: C), nor in the inhibitory activity of DQT. On the other hand, we found that IFN beta was induced under the same conditions and that its expression was inhibited by DQT. Kinetic analysis showed that an increase in IFN beta concentrations occurred 4-8 h after poly(I: C) treatment, while the concentration of CXCL10 was undetectable at that time and started to increase later, when IFN beta reached high levels. Therefore, DQT may be regarded as a new promising inhibitor of IFN beta expression and IFN beta-dependent downstream genes and proteins, e.g., CXCL10 chemokine, which is implicated in the pathogenesis of autoimmune diseases.
