Molecular Docking and Receptor-Based 3D-QSAR Studies on Aromatic Thiazine Derivatives as Selective Aldose Reductase Inhibitors

Aromatic thiazine derivatives were proved to be potent aldose reductase inhibitors (ARIs) with high selectivity for aldose reductase (ALR2) over aldehyde reductase (ALR1). Molecular docking and three-dimensional quantitative structure-activity relationship (3D-QSAR) studies are conducted on a dataset of 44 molecules to explore the interactions between aromatic thiazine derivatives and ALR2. The superposition of ALR2 and ALR1 active sites indicate that residues Leu 300 and Cys 298 from ALR2 may explain the good selectivity of the most active compound 1m. The comparative molecular field analysis (CoMFA) model (q(2) = 0.649, r(2) = 0.934; q(2): cross-validated correlation coefficient, r(2): non-cross-validated correlation coefficient) and comparative molecular similarity indices analysis (CoMSIA) model (q(2) = 0.746, r(2) = 0.971), based on the docking conformations of these compounds, are obtained to identify the key structures impacting their inhibitory potencies. The predictive power of the developed models is further validated by a test set of seven compounds, resulting in predictive r(Pred)(2) values of 0.748 for CoMFA and 0.828 for CoMSIA. 3D contour maps, drawn from 3D-QSAR models, reveal that future modifications of substituents at the C3 and C4 positions of the benzyl ring and the C5 and C7 positions of the benzothiazine-1,1-dioxide core might be favorable for improving the biological activity, which are in good accordance with the C7 modification results reported in our earlier work. The information rendered by 3D-QSAR models could be helpful in the rational design of novel ARIs with good inhibitory activity to treat diabetic complications in the future.

Crystal structure of rac-2,3-diphenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one 1-oxide

In the title compound, C(16)Hi(5)NO(2)S [alternative name: rac-2,3-diphenyl-1,3-thiazinan-4-one 1-oxide], the thiazine ring exhibits an envelope conformation, with the S atom forming the flap. The sulfoxide 0 atom is in a pseudo-axial position on the thiazine ring and is trans to the phenyl group on C-2. The phenyl rings form a dihedral angle of 89.47 (19)degrees. In this racemate crystal, homochiral molecules form slabs parallel to (010) of thickness b/2 which then stack with alternating chirality in the b-axis direction. The stacking is aided by edge-to-face interactions between the phenyl rings of racemic molecules. Within each of the single-enantiomer slabs, the molecules are held by C-H center dot center dot center dot O-type interactions, with an H center dot center dot center dot O distance of 2.30 angstrom, forming infinite chains along the c-axis direction, as well by the edge-to-face interactions between phenyl rings of neighboring molecules in the a-axis direction.

Electrochemical Evaluation and DFT Studies of 2-(4-chlorophenyl)-3-hydroxy-4,6-dioxo-8-phenyl-4,6-dihydropyrimido[2,1-b][1,3]thiazine-7-carbonitrile of Carbon Steel Corrosion in Hydrochloric Acid

In present study corrosion inhibition property of 2-(4-chlorophenyl)-3-hydroxy-4,6-dioxo-8-phenyl-4,6-dihydropyrimido[2,1-b][1,3]thiazine-7-carbonitrile (CHPPC) in 1.0 M HCl was investigated using electrochemical impedance spectroscopy, potentiodynamic polarization and DFT studies. From electrochemical measurements it is observed that inhibition efficiency increases with CHPPC concentration and maximum efficiency (98.9) was obtained at 1.0 mM. The potentiodynamic study reveals that pyrimidothiazine derivative is a mixed type inhibitor with predominant cathodic action. EIS plot indicates that the addition of inhibitor increases the charge-transfer resistance (Rct) and decreases the double-layer capacitance (Cdl) of the corrosion process, these observation reveal that investigated pyrimidothiazine derivative inhibits carbon steel corrosion by adsorption mechanism. Adsorption of pyrimidothiazine derivative on carbon steel surface obeys the Langmuir adsorption isotherm. The effect of temperature on the corrosion rate was investigated and some thermodynamic parameters were also calculated in order to explain the mechanism of adsorption. A theoretical study of the corrosion inhibition efficiency of this pyrimidothiazine derivative, was carried out using density functional theory (DFT) at the B3LYP/6-31G(d) level of theory.

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 7143-01-3. Formula: C2H6O5S2.

Ecofriendly pH-Tunable Hydrogels for Removal of Perilous Thiazine Dye

Reactive dyes are extremely toxic and harmful to the environment even present at very low concentration. In this study, sodium alginate based reusable hydrogels was prepared for the removal of methylene blue from waste water. pH-tunable hydrogels was prepared by the introduction of ionic pendant functionalities on sodium alginate (SA) by the utilization of ethylene glycol and acrylic acid through condensation followed by free radical polymerization. The structure, formation and thermal stability of hydrogel was identified by Fourier transform infra red spectroscopy and thermogravimetric analysis respectively. Swelling nature at different pH ranges and the humidity contents of both dried and dye adsorbed hydrogels was investigated. The morphology of the dry and dye adsorbed hydrogel was also studied using scanning electron microscopy. The swelling studies infer that pronounced swelling obtained at higher pH than at lower pH. The surface morphology of plain hydrogel before and after adsorption of methylene blue (MB) was examined by SEA analysis. The adsorption tendency of the SEA hydrogel in MB was steadily investigated at different pH, contact time, concentration dye and adsorbent dosage. All prepared hydrogels were performed well in the removal of MB from waste water up to 80-98%. Recycling of hydrogels has a vital role for waste water treatment and it can be done by desorption studies which shows that 0.1 N HCl revealed higher elution efficiency i.e. 90.00%. Furthermore, adsorption-desorption studies suggested that SA based hydrogels contributes to enhance the removal efficacy, which renders the hydrogels well-designed for the efficient removal of cationic dyes (MB). However, polyol based hydrogels have been chosen for an adsorbent because of low-cost, ecofriendly, biocompatible and efficient biosorbents. [GRAPHICS] .

Reinvestigations into synthesis of allyldithiocarbamates and their intramolecular cyclization: synthesis and antihyperglycemic activity of 2-thioxothiazolidine-4-alkanoates

Reinvestigating the synthesis of allylthiocarbamates from MBH derivatives revealed that they are obtained more efficiently from allylbromides in isopropanol rather than acetates in water. Further unlike reported, the base-mediated intramolecular cyclization of these allyldithiocarbamates give substituted 2-thioxothiazolidine-4-alkanoates instead of substituted 1,3-thiazines and the reaction was restricted to 2- or 4-nitrophenyl carrying substrates. Screening of these products for antihyperglycemic activity revealed that 5bC displays significant activity via partial agonist activity on PPAR gamma at transcriptional level, which was corroborated by molecular docking studies.

Comparative transcriptome analysis of Anguilla japonica livers following exposure to methylene blue

The thiazine dye methylene blue is widely used as a disinfectant and antidote in veterinary medicine. Here, we compared transcriptome differences in the liver of Anguilla japonica exposed to methylene blue using Illumina RNA sequencing technology. A total of 75,953,174 and 86,499,866 clean reads with an average length of 126bp from control and treatment groups respectively. A total of 148,238 transcripts were assembled, with 62,152 components were assembled. Overall, 416,991 unigenes were checked against the National Center of Biotechnology Information, Non-redundant, Cluster of Orthologous Groups (COG), and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases. Of these, 18,541 genes were judged to be differently expressed. The gene ontology (GO) terms molecular function and biological process were the most enriched in protein binding, followed by ATP binding and regulation of transcription, and DNA-dependent. KEGG pathway analysis revealed significant enrichment of N-glycan biosynthesis and the citrate cycle. This study determined that unigenes related to transmembrane transport and drug metabolism in A.japonica were differentially expressed following exposure to methylene blue. These findings can shed insight into the mechanism of methylene blue metabolism in this economically important species.
