Ru-II(eta(6)-p-cymene) Complexes of Bioactive 1,2-Benzothiazines: Protein Binding vs. Antitumor Activity

1,2-Benzothiazine-3-carboxamide 1,1-dioxide derivatives such as meloxicam are known to display numerous pharmacological activities. We prepared a series of 4-hydroxy-2-alkyl-2H-benzo[e][1,2]thiazine-3-carboxamide 1,1-dioxide ligands 1a-f and their Ru((6)-p-cymene) complexes 2a-f, inspired by synergistic effects observed with other bioactive ligands coordinated to metal centres. The molecular structures of 1a, 2a, and 2b were determined by X-ray diffraction analyses. The stability of the metal complexes was characterized in DMSO and DMSO/H2O on the basis of H-1 NMR spectroscopy and their protein binding capabilities were studied using mass spectrometry. In vitro cytotoxicities of the Ru complexes were determined against human colorectal carcinoma (HCT116), non-small cell lung carcinoma (NCI-H460) and cervical carcinoma (SiHa) cell lines. The low levels of biological activity observed for these Ru complexes were put into context by considering their chemical reactivity with proteins. The binding of proteins resulted in cleavage of the benzothiazine backbone when the complex was present in concentrations equimolar with respect to protein.

Kinetics of palladium nano-particles catalyzed reduction of Methylene Green by hydrazine: Role of induction period in determining mechanistic pathway

Methylene Green (MG), a thiazine dye, is catalytically reduced by N2H4 in presence of palladium nanoparticles (Pdn) in buffer media. The observed rate, k(o) increases with increase in [Pdn], [N2H4] and pH but decrease with increase in ionic strength (maintained with NaNO3). Unlike other thiazine dyes, the catalyzed reduction of MG shows an induction period which is caused by the restructuring of Pdn surface. The rate of adsorbate-induced surface restructuring which increase with increase in [N2H4] but independent of [MG], suggest that only N2H4 is adsorbed on Pdn surface during the catalyzed reaction. Interestingly, NO3 ions are also adsorbed on the Pdn surface and turn the surface negatively charged. The reductant, N2H4 is adsorbed on this negatively charged Pdn surface before it reacts with MG. The surface restructuring energy of Pdn, though is constant (78.8 +/- 1.6 kJ M-1) over the temperature range of 288-313 K but the activation energy for the catalyzed reduction varies with temperatures. The convex Arrhenius plot illustrates that activation energy is different in lower (288-304 K, 123.8 +/- 12.6 kJ M-1) and higher temperature range (304-313 K, 69.2 +/- 2.1 kJ M-1) and around the inversion temperature, Tinv (304 K) a change in the nature of transition state takes place.

The double Smiles rearrangement in neutral conditions leading to one of 10-(nitropyridinyl)dipyridothiazine isomers

Phenothiazines are reported to exhibit very promising anticancer, antibacterial, antifungal, anti-inflammatory activities, reversal of multidrug resistance and many other actions. Synthesis of phenotiazines is mostly carried cyclization of o-aminodiphenyl sulfides proceeded through the Smiles rearrangement. The modifications of the phenothiazine structure via the substitution of the benzene ring with the pyridine ring gave various pyridobenzothiazines and dipyridothiazines. The reaction of 3-amino-3′-nitro-2,2′-dipyridinyl sulfide with 4-chloro-3-nitropyridine in sole DMF led to one of four possible isomeric nitropyridinyldipyridothiazines. Two-dimensional H-1 and C-13 NMR experiments (COSY, ROESY, HSQC and HMBC) were used to reveal the right product structure as 10-(3′-nitro-4′-pyridinyl) dipyrido[2,3-b; 2′,3′-e] [1,4]thiazine (10-(3′-nitro-4′-pyridinyl)-1,6-diazaphenothiazine). The final structure confirmation came from a single crystal X-ray analysis. This structure is the result of very rare reaction mechanism involving the double Smiles rearrangement of the S-N type. The tricyclic dipyridothiazine system is unexpectedly almost planar, with the butterfly angle of 176.39(4) between two pyridine rings and 174.17(6)degrees between the halves of the thiazine ring (the NCCS) planes. The pyridinyl substituent is rotated about N10-C11 bond and oriented almost perpendicularly to the tricyclic ring system with the dihedral angle between the two planar systems of 94.93(3)degrees. The nitropyridinyl substituent is located quasi-equatorially with the S center dot center dot center dot N10-C11 angle of 176.92(8)degrees. The nitro group is tilted from the pyridine ring by 128.44(8)degrees. (C) 2016 Elsevier B.V. All rights reserved.

Sublimation enthalpy of 1,3-thiazine structural analogues: Experimental determination and estimation based on structural clusterization

The saturated vapor pressures of 4 nonaromatic bicyclic 1,3-thiazine and 1,3-selenazine derivatives have been measured by the method of transpiration by inert gas-carrier in the temperature range of 308-392 K. Based on the experimental data the thermodynamic functions of sublimation have been calculated. The sublimation enthalpies of the compounds vary from 104 to 150 kJ mol(-1) depending on the chemical nature of the substituent in the aryl moiety and the heteroatom in the bicyclic fragment. The crystal lattice energy of thiazines decreases with the introduction of substituents in the following order: cyano > acetyl > isopropyl. New approach has been suggested to evaluating sublimation enthalpy of the studied and structurally related compounds by using clusterization of the space of experimental points.

Removal behaviour of a thiazine, an azo and a triarylmethane dyes from polluted kaolinitic soil using electrokinetic remediation technology

In this study, we investigated the potentiality of the electro-kinetic remediation (EKR) technique for the removal of organic dyes polluted soil. Methylene blue (MB), methyl orange (MO), and phenol red (PR) are representing a thiazine, an azo, and a tryarilmethane dye respectively, which was spiked with kaolinite were selected as a model for pollutant dyes tests. An EKR tool (15 cm length) equipped with a DC electric current with the maximum values of 30 V. Graphite electrodes were used for both anode and cathode was set up for two weeks operation. As a result, only 40-55 % of dye was removed from the soil sections by using distilled water. However, by the addition of some electrolytes; the percentage of dyes removed from the soil increased from 73-76 % and 85-89 % for sodium sulphate, and monosodium dihydrogen phosphate, respectively. It resulted that 55-64 % of dyes was removed without controlling the pH. The significant improvement was achieved by controlling the pH of the system. By controlling the pH in the cathode chamber, only 23 % of MB, 25 % of MO, and 18 % of PR dyes remain in the soil sections, respectively. While by controlling the pH in the anode chamber, almost 90 % of tested dyes could be removed from the kaolinite chamber effectively. The movement of a thiazine dye, from the anode to the cathode chamber was controlled by electro-migration and electro-osmosis phenomena. An azo dye transported from the cathode to the anode chamber by a similar process. However, a triarylmethane dye was removed from the soil sections by only electro-osmosis process. For three kinds of tested dyes, it were found that electro-osmotic flow moving from the anode to the cathode directions. The ageing of dye affects the removal percentage of the dye.

Surface functionalizedCasuarina equisetifoliapine powder for the removal of hetero-polyaromatic dye: characteristics and adsorption

The seed ofCasuarina equisetifolia, the genus of Pinus of the familyPinaceaewas examined for the potentiality of adsorbing a thiazine-based hetero-polyaromatic dye from water system. For which, the surface functionalization ofCasuarina equisetifolia(SFCE) was achieved through H(2)SO(4)acidic bath to treat methylene blue (MB) dye contaminated water. The SFCE was characterised using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) to analyse morphological, physical and chemical behaviour after surface modification. The effects of adsorption process influencing variables such as pH, concentration of MB dye, contact time and temperature was examined. The maximum adsorption capacity of 0.5 gL(-1)SFCE for the concentration ranging from 20 to 100 mgL(-1)of MB was investigated using different variables. The effect of parameters including pH, time and temperature were optimised at a speed of agitation of 150 rpm. The adsorption data retrieved from batch experiments were fit with Langmuir, Freundlich, Temkin and Dubinin-Raduskevich (D-R) isotherm models, and as a result, Freundlich presents the best fit (R-2 > 0.97). Pseudo-second order kinetic was superior indicating that SFCE-MB system has undergone the chemisorption mechanism (R-2 > 0.99) spontaneously. Overall, the tested system with synergistic effect was witnessed with maximum adsorption efficiency of 42.19 mg g(-1)to remove dye from industrial wastewater.
