Polymer-Supported Syntheses of Heterocycles Bearing Oxazine and Thiazine Scaffolds

In this review, we summarize synthetic approaches to preparing single or fused oxazine and thiazine derivatives using solid-phase synthesis (SPS). The literature survey revealed that diverse compounds bearing variously functionalized 1,2-oxazine, 1,3-oxazine, or 1,4-oxazine scaffolds and the corresponding thiazines are accessible by SPS. The latest contributions involving the stereoselective polymer-supported syntheses of morpholines indicate that the field is continuing to expand.

Topically applied azaphenothiazines inhibit experimental psoriasis in mice

The therapeutic efficacy of topically applied azaphenothiazine derivatives: 9-chloro-6-acetylaminobutylquinobenzo[3,2-b] [1,4]thiazine (compound 4) and 6-chloroethylureidoethyldiquino[3,2-b;2′;3′-e] [1,4]thiazine (compound 5) in the amelioration of inflammatory symptoms of imiquimod-induced psoriasis in mice was investigated. Clobederm (R), containing clobetasol propioniate, served as a reference drug. The application of the compounds led to thinning of the epidermis and reduction of the cell layers. The suppressive actions of the compounds were even stronger with regard to pathological changes of the dermis. The compounds also exerted generalized, anti-inflammatory effects by decreasing the number of circulating leukocytes, lowering subiliac lymph node weight and partially normalizing an altered blood cell composition. The changes in the composition of main cell types in the epidermis and dermis were less affected by the compounds. In addition, both compounds inhibited to a similar degree production of tumor necrosis factor alpha (TNF alpha) in human whole blood cell culture. Whereas compound 5 strongly inhibited IL-8 and CXCL10 chemokines in human keratinocytes – KERTr cell line, transfected with poly(I:C), the suppressive action of compound 4 in this model was weak. In addition, compound 5, but not compound 4, exhibited at low doses proapoptotic properties with regard to colonic cell lines. In summary, we demonstrated the therapeutic potential of two selected azaphenotiazines in the amelioration of the skin pathology elicited in a mouse experimental model of psoriasis.

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] .

Lipophilicity estimation of anti-proliferative and anti-inflammatory 6-substituted 9-fluoroquino[3,2-b]benzo[1,4]thiazines

The lipophilicity parameters (logP(calcd), R-M0 and logP(TLC)) of 17 new anti-proliferative and anti-inflammatory tetracyclic 6-substituted 9-fluoroquinobenzothiazines were determined theoretically using computational methods and experimentally by reversed-phase thin-layer chromatography. The experimental parameter R-M0 was determined on the RP-18 silica plates with acetone-aqueous TRIS buffer as mobile phase. The obtained parameter R-M0 was further transformed into parameter logP(TLC) by use of the calibration curve. The theoretical logP(calcd) values differed depending on the substituents and nature of calculating programs. Fluoroquinobenzothiazines turned out to be rather middling or highly lipophilic compounds. The parameter R-M0 and specific hydrophobic surface area b were meaningly intercorrelated showing congeneric two classes of quinobenzothiazines. The calculated logP(calcd) and experimental logP(TLC) values were compared and intercorrelated to show different prediction power of the computational programs. The lipophilicity was correlated with molecular descriptors (molar mass, molar volume, and molar refractivity), biomolecular descriptors (HIA, PB, MDCK, Caco-2, and BBB) and in vitro tested biological activities (tumor necrosis factor alpha inhibition and antiproliferative activity).

Poorly soluble drugs: disbalance of thermodynamic characteristics of crystal lattice and solvation

The dissolution processes in aqueous media of poorly soluble drugs belonging to the classes of spiro derivatives, benzoic acid and its derivatives, sulfonamides, fenamates, and thiadiazoles were analyzed based on the data recently published by the author. The main criterion for the solubility analysis was the comparison of the thermodynamic characteristics of sublimation processes (state of the molecules in solids) and solvation (state of the molecules in solutions) under structural modification of the reference molecule. The characteristics of the processes under investigation were compared by the superposed diagram approach which allows complete information to be obtained about the thermodynamic state of the molecules in crystal and solution. A variety of thermodynamic paths of the molecules undergoing structural modification (design) was shown. The extreme solubility values were obtained for the considered classes of compounds which can be derived by structural modification of the substances. A classification of the drugs was suggested based on the analysis of the determinative steps of the dissolution processes: crystal or solvation controlled. Based on the investigation of 59 drugs belonging to five different classes of compounds, it was estimated that for 50.7% of the compounds the solubility processes were crystal controlled, whereas for the rest 49.3% – solvation controlled. Among all the considered compounds, a structural modification of the reference one led to a solubility enhancement only in 22.1% of the substances. And in 85% of the compounds, the dissolution processes were solvation controlled and in the remaining 15% – crystal controlled.

Access to SCN-containing thiazolines via electrochemical regioselective thiocyanothiocyclization of N-allylthioamides

An electrochemical thiocyanothiocyclization of N-allylthioamides has been developed for the synthesis of SCN-containing 2-thiazolines. This method provides a green and efficient approach to generate 5-exo-cyclization 2-thiazolines with a broad substrate scope and good yields. In addition, 6-endo-cyclization isothiocyanato thiazines are formed regioselectively when cyclic thioamides are used as reactants. The reaction is easy to proceed under catalyst-, additive- and oxidant-free conditions.

Preparation and biological evaluation of conformationally constrained BACE1 inhibitors

The BACE1 enzyme is a key target for Alzheimer’s disease. During our BACE1 research efforts, fragment screening revealed that bicyclic thiazine 3 had low millimolar activity against BACE1. Analysis of the co-crystal structure of 3 suggested that potency could be increased through extension toward the S3 pocket and through conformational constraint of the thiazine core. Pursuit of S3-binding groups produced low micromolar inhibitor 6, which informed the S3-design for constrained analogs 7 and 8, themselves prepared via independent, multi-step synthetic routes. Biological characterization of BACE inhibitors 6-8 is described. (C) 2015 Elsevier Ltd. All rights reserved.

The corrosion inhibition of carbon steel in a 1.0 M HCl solution, using 4-amino-2-(4-chlorophenyl)-8-(2,3-dimethoxyphenyl)-6-oxo-2,6-dihydropyrimido[2, 1b][1,3] thiazine-3,7-dicarbonitrile (ACMPT) was investigated by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and quantum chemical calculations. Polarization curves indicate that the studied compound was acting as a mixed inhibitor with predominant cathodic effectiveness. The inhibition efficiency decreased with an increased temperature, and the thermodynamic and activation parameters obtained from this study were discussed. The adsorption behavior of ACMT follows Langmuir’s isotherm. In addition, Density Function Theory (DFT) calculations were performed on the studied molecule. The theoretical parameters obtained from this method are in good agreement with the experimental results.
