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.

Sex-Specific Differences of Steroid Receptors Following Exposure to Environmentally Relevant Concentrations of Phenothiazine in Fundulus heteroclitus

Phenothiazine (PTZ) is a heterocyclic thiazine compound used for industrial and medical purposes. Through environmental surveillance studies, PTZ was found being discharged into a local river in Connecticut. Phenothiazine has been shown to act similarly to endocrine disrupting chemicals. This study sought to identify sex specific hormone receptor changes inFundulus heteroclitusin response to PTZ exposure.Fundulus heteroclitus,also known as mummichog, are small fish native to the Atlantic coast of the United States and Canada. They reside in brackish waters and can survive harsh toxic environments. This model organism is native to the polluted waters found in Connecticut. In this study, fish were exposed to PTZ concentrations of 0.5 ppm, 1.0 ppm, and 2.0 ppm for 1 week. Following exposure, brain, liver, and gonad tissues were harvested; cDNA was synthesized; and mRNA expression was assessed for 6 different hormone receptors. Compared with vehicle control (ethanol) differences in mRNA expression, levels of hormone receptors were observed in various tissues from male and female fish. Many of the tissues assessed showed changes in expression level, while only female liver and testis showed no change. These results implicate PTZ as a potential endocrine disrupting compound to mummichog at environmentally relevant concentrations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 110553-27-0, in my other articles.

Synthesis of A Novel Heterocyclic System of 3,8-Disubstituted-5H-Pyrimido[5′,4′:5,6][1,4]Thiazino[3,2-e][1,2,4]Triazine

The new compounds 6-methyl-8-morpholino-2Hpyrimido[5′,4′:5,6][1,4]thiazino[3,2e][1,2,4]triazin-3(5H)-one(3a)and 6-methyl-8-(piperidin-1-yl)-2Hpyrimido[5′,4′:5,6][1,4]thiazino[3,2-e][1,2,4]triazin-3(5H)-one(3b)were obtained from cyclocondensation of 6-bromo-1,2,4-triazine-3,5(2H,4H)-dione(1)with appropriate 5-amino-6methylpyrimidine-4-thiol (2a, b)in dimethylformamide and in the presence of potassium carbonate under reflux. Reaction of compounds(3a, b)with phosphorous oxychloride gave 4-(3-chloro-6-methyl-5H-pyrimido[5′,4′:5,6][1,4]thiazino[3,2-e][1,2,4]triazin-8-yl)morpholine(4a)and 3-chloro-6-methyl-8-(piperidin-1-yl)-5H-pyrimido[5′,4′:5,6][1,4]thiazino[3,2-e][1,2,4]triazine(4b). Nucleophilic substitution of chlorine atom of compounds(4a, b)with typical secondary amines in DMF and K(2)CO(3)produced the new derivatives of the 3,8-disubstituted-5H-pyrimido[5′,4′:5,6][1,4]thiazino[3,2-e][1,2,4]triazine ring systems(5a-f). All the synthesized products were characterized and confirmed by their spectroscopic and microanalytical data.

Synthesis, spectroscopic studies, DFT calculations, antimicrobial and antitumor activity of tridentate NNO Schiff base metal complexes based on 5-acetyl-4-hydroxy-2H-1,3-thiazine-2,6(3H)-dione

New Schiff base ligand was prepared by condensation of 5-acetyl-4-hydroxy-2H-1,3-thiazine-2,6(3H)-dione with o-phenylenediamine. Cu(II), Ni(II), Co(II), VO(IV), Zn(II), Cd(II) and UO2(VI) complexes were prepared and characterized on the basis of elemental analyses, IR, (H-1 and C-13) NMR, electronic, ESR and mass spectra; magnetic, molar conductance measurements as well as thermal gravimetric analysis. The coordination sites of the Schiff base ligand are phenolic oxygen, azomethine nitrogen and amino group nitrogen; where the ligand acts as monobasic tridentate. All results established that all compounds have 1:1 (metal: ligand) stoichiometry except Ni(II)- and VO(IV)- complexes have 1:2 (metal: ligand) stoichiometry. The metal complexes showed octahedral geometry except Cu(II) complex which showed square planar arrangement and UO2(VI) has pentagonal bipyramidal arrangement. Thermodynamic parameters were calculated for the ligand and its metal complexes using Coats-Redfern method. The ligand and its complexes were tested in vitro bioassays against some Gram-negative and Gram-positive bacteria and the fungus strain; showing good results for some of these compounds. The antitumor activity of the ligand and its copper(II) and oxovanadium(IV) complexes was investigated against HepG2 cell line. Density Function Theory (DFT) level implemented in the Gaussian 09 program was used to optimize structure and some structural parameters of the ligand and its metal complexes such as: total energy, HOMO, LUMO as well as dipole moment. The computed data were correlated with the experimental results. (C) 2019 Elsevier B.V. All rights reserved.

Alkylation of 5-(3-chlorobenzo[b]thien-2-yl)-1,2,4-triazole-3-thione with Epichlorhydrin and the Role of MW and Solid Support in the Reaction

An efficient eco-friendly approach has been adopted for the selective synthesis of 2,3-epoxypropylsulfanyltriazole 4 from the reaction of 1-chloro-2,3-epoxy-propane (2) with 5-(3-chlorobenzo[b]thien-2-yl)-4H-1,2,4-triazole-3-thione (1) under solvent free microwave conditions in the presence of a solid support. Instead, when the mixture of reactants was irradiated for prolonged time in the absence of solid support, triazolo[2,1-b]thiazine 3 was exclusively afforded in excellent yield. On the other hand, performing the irradiation in the presence of a base, mixtures of compounds 4 and 3 were obtained; the ratio of the two products was dependent on the nature of the base, although 4 was the major product in each case.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 110553-27-0 help many people in the next few years. Recommanded Product: 110553-27-0.

Crystal structure, Hirshfeld surface analysis and interaction energy, DFT and antibacterial activity studies of ethyl 2-[(2Z)-2-(2-chlorobenzylidene)-3-oxo-3,4-dihydro-2H-1,4-benzothiazin-4-yl]acetate

The title compound, C19H16ClNO3S, consists of chlorophenyl methylidene and dihydrobenzothiazine units linked to an acetate moiety, where the thiazine ring adopts a screw-boat conformation. In the crystal, two sets of weak C-HPh center dot center dot center dot ODbt (Ph = phenyl and Dbt = dihydrobenzothiazine) hydrogen bonds form layers of molecules parallel to the bc plane. The layers stack along the aaxis direction with intercalation of the ester chains. The crystal studied was a two component twin with a refined BASF of 0.34961 (5). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H center dot center dot center dot H (37.5%), H center dot center dot center dot C/C center dot center dot center dot H (24.6%) and H center dot center dot center dot O/O center dot center dot center dot H (16.7%) interactions. Hydrogen-bonding and van der Waals interactions are the dominant interactions in the crystal packing. Computational chemistry indicates that in the crystal, C-H-Ph center dot center dot center dot O-Dbt hydrogen bond energies are 38.3 and 30.3 kJ mol(-1). Density functional theory (DFT) optimized structures at the B3LYP/ 6-311 G(d,p) level are compared with the experimentally determined molecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap. Moreover, the antibacterial activity of the title compound has been evaluated against gram-positive and gram-negative bacteria.

Titania-loaded cellulose-based functional hybrid nanomaterial for photocatalytic degradation of toxic aromatic dye in water

The dispersion of Titania on cellulose nanowhiskers was achieved using titanium tetra-isopropoxide as the precursor and sulphuric acid as a peptizing agent via the low-temperature sol-gel synthesis method. The photocatalytic activity of the resultant hybrid catalyst was studied through photocatalytic removal of toxic aromatic cationic thiazine dye (methylene blue). Diverse instrumental methods used for full characterizations of pristine and prepared materials allowed correlating the type of the chemical moiety incorporated to the formation of Titania-loaded cellulose-based functional nanomaterial as well as its stability and catalytic performance. Results indicated successful synthesis of multiscale Titania (19 nm similar to 1 mu m) and perpetual distribution over cellulose nanowhiskers. The latter showed high photocatalytic behavior towards the degradation of methylene blue (conc. 50 ppm) dye. The degradation reached 98.5 % in 40 min at a reaction rate of 0.188 min(-1) as observed and measured through UV-vis spectrophotometer. Chemical oxygen demand (COD) analysis reveals substantial mineralization of the pollutants by reducing toxicity up to 68.64 % with complete recovery of the catalyst validated by total dissolved solids (TDS) analysis of treated water. Considering the above results, a mechanism has postulated. Kinetic study showed that the degradation reaction obeys pseudo-first-order reaction kinetics with appreciable recyclability after five (05) repeated uses. The results herein open new prospects for cellulose-based functional nanomaterial for various environmental applications.
