New pyrimidothiazine Derivative as Corrosion Inhibitor for Carbon Steel in Acidic Media

2,8-bis(4-chlorophenyl)-3-hydroxy-4,6-dioxo-4,6-dihydropyrimido[2,1-b][1,3]thiazine-7-carbonitrile (CHPTC) was tested as corrosion inhibitor for carbon steel in 2.0 M H3PO4 by using polarization, electrochemical impedance spectroscopy (EIS) and computational calculations. Potentiodynamic polarization curves indicated that the pyrimidothiazine derivativeas mixed-type inhibitor. Impedance measurements showed that the double-layer capacitance decreased and charge-transfer resistance increased with increase in the inhibitor concentration and hence increasing in inhibition efficiency. The effect of temperature on the corrosion behavior of carbon steel in 2.0 M H3PO4 with and without addition of CHPTC was studied in the temperature range 313-333 K. The adsorption of the inhibitor molecules was in accordance with the Langmuir adsorption isotherm. Quantum chemical approach used to calculate electronic properties of the molecule to ascertain the relation between inhibitive effect and molecular structure.

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.

Comparison of dye (oxazine and thiazine) materials as a photosensitizer for use in photogalvanic cells based on molecular interaction with sodium dodecyl sulphate by spectral study

The photochemistry of dye is playing a significant role for understanding the mechanism of electron transfer reactions in photoelectrochemical devices such as photogalvanic cells, DSSC, semiconductor photo-catalysis, photoconductors, etc. Oxazines (Brilliant Cresyl Blue and Nile Blue O) and thiazines (Azur A, Azur B, Azur C, Methylene Blue and Toluidine Blue O) dyes have been used widely as a photosensitizer with and without surfactants in the photogalvanic cells for solar power conversion and storage. Since, the stability and solubility of photosensitizers (dyes) are increased in the presence of surfactant and these properties lead to enhance the electrical output of the photogalvanic cells. Therefore, here we have studied the extent of interaction of different dyes with sodium dodecyl sulphate (SDS), find out the order of stability of dye-SDS on the basis of magnitudes of shifting in lambda(max) of dye monomer and try to correlate order of dye-SDS interaction with already reported electrical output data of photogalvanic cells. Brilliant Cresyl Blue, Nile Blue O, Azur A and TB O have shown red shifting while Azur B, Azur C and MB have shown blue shifting in their lambda(max) value with SDS, which indicates formation of dye-surfactant complex. But, the extent of formation of complex for different dyes with SDS was different due to change in their alkyl groups. Dyes with red shifting have greater stability in excited state as well as higher electrical output data of the cell than dye with blue shifting. On the basis of both red and blue shifting, order of stability of dyes-SDS complex was found as: Brilliant Cresyl Blue > Toluidine Blue O > Azur A > Nile Blue > Azur B > Methylene Blue > Azur C. The order of electrical output values of these dyes in photogalvanic cells have also been supported by literature data in the presence of SDS. Hence, the dye-surfactant complex which would have greater stability in excited state might be more useful for improvement of conversion efficiency and storage capacity of photogalvanic cells in the future.

Hydrazide-integrated carbazoles: synthesis, computational, anticancer and molecular docking studies

A new class of carbazole-based hydrazides 6a-c, synthesized from carbazole by employing a multistep synthetic strategy, has been described. Detailed insight into their structures (6a-c) has been elucidated by UV-Vis, FT-IR and NMR (H-1 and C-13) spectroscopic studies. Theoretical investigation of the molecules 6a-c has been accomplished utilizing DFT and TD-DFT techniques with the B3LYP/6-311++G(d,p) method. Theoretical findings such as optimized structural, vibrational, and electronic properties, and proton and carbon chemical shifts of the targets 6a-c are in harmony with their experimental results and/or structurally related reported ones. Cytotoxicity of the target hydrazides 6a-c has been evaluated using human pancreatic cancer cells (AsPC1 and SW1990). The hydrazides 6a-c displayed a significant in vitro cytotoxic effect against both the pancreatic cancer cells AsPC1 (concentration that inhibits 50% cell viability, IC50: 3.42 +/- 0.41 mu M for 6a) and SW1990 (IC50: 22.42 +/- 1.40 mu M for 6a). The superior binding energy resulting from the in silico molecular docking approach of the hydrazide 6a indicates its greater affinity towards the receptor (binding energy: -8.63 kcal mol(-1) and IC50: 475.05 nM). Thus, the hydrazide 6a could serve as a new lead for the development of anticancer agents.

Synthesis and oral hypoglycemic effect of novel thiazine containing trisubstituted benzenesulfonylurea derivatives

A new series of 3-(4-substituted phenyl)-1-(4-(4,6-dimethyl-6H-1,3-thiazin-2-yl)phenylsulfonyl)-1-substituted urea (5a-o) was synthesized by an effectual route via sulfonylcarbamates and explores the novel site for substitution in sulfonylurea as well as the way of thiazine can be prepared. The molecules were established by elemental analysis and spectroscopic viz. IR, H-1 NMR, C-13 NMR and MS techniques. All the fifteen derivatives were shown very prominent oral hypoglycemic effect at the dose of 40 mg/kg body weight (p.o.) in respect of standard drug glibenclamide and control. The hypoglycemic effect was studied using oral glucose tolerance test in normal and NIDDM in STZ-rat model. The compounds 5a, 5d, 5f, 5i, 5k and 5n were dominant out of fifteen derivatives for blood glucose lowering activity (more than 80%) when comparing with NIDDM control. These derivatives were either containing simply phenyl ring (5a, 5f and 5k) on to the second amine of sulfonylurea (R’ = H) or nitro group at the para position in compound 5d, Si and 5n (R’ = NO2) to produce significant oral hypoglycemic effect. Other structural activity relationship is also observed regarding the heteroaromatic and substituted aromatic group at R and R’ position respectively.

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.

I am very proud of our efforts over the past few months and hope to 10297-73-1 help many people in the next few years. Safety of 4′-(Methylsulfonyl)acetophenone.
