Characterization and photocatalytic performance evaluation of various metal ion-doped microstructured TiO2 under UV and visible light

Commercially available microcrystalline TiO2 was doped with silver, ferrous and ferric ion (1.0mol %) using silver nitrate, ferrous sulfate and ferric nitrate solutions following the liquid impregnation technology. The catalysts prepared were characterised by FESEM, XRD, FTIR, DRS, particle size and micropore analysis. The photocatalytic activity of the prepared catalysts was tested on the degradation of two model dyes, methylene blue (3,7-bis (Dimethylamino)-phenothiazin-5-ium chloride, a cationic thiazine dye) and methyl blue (disodium;4-[4-[[4-(4-sulfonatoanilino)phenyl]-[4-(4-sulfonatophenyl)azaniumylidenecyclohexa-2,5-dien-1-ylidene]methyl]anilino]benzene sulfonate, an anionic triphenyl methane dye) under irradiation by UV and visible light in a batch reactor. The efficiency of the photocatalysts under UV and visible light was compared to ascertain the light range for effective utilization. The catalysts were found to have the anatase crystalline structure and their particle size is in a range of 140-250nm. In the case of Fe2+ doped TiO2 and Fe3+ doped TiO2, there was a greater shift in the optical absorption towards the visible range. Under UV light, Ag+ doped TiO2 was the most efficient catalyst and the corresponding decolorization was more than 99% for both the dyes. Under visible light, Fe3+ doped TiO2 was the most efficient photocatalyst with more than 96% and 90% decolorization for methylene blue and methyl blue, respectively. The kinetics of the reaction under both UV and visible light was investigated using the Langmuir-Hinshelwood pseudo-first-order kinetic model. Kinetic measurements confirmed that, Ag+ doped TiO2 was most efficient in the UV range, while Fe3+ doped TiO2 was most efficient in the visible range.

Heteroannelation of Cyclic Ketones: Synthesis, Characterization and Antitumor Evaluation of Some Condensed Azine Derivatives

A series of pyrimidine and thiazine derivatives was synthesized by one-pot reaction of cyclopentanone with a mixture of an aromatic aldehyde, namely o-anisaldehyde, and different ureas, namely urea, guanidine and thiourea, respectively. Furthermore, cycloaddition reaction of active methylene reagents, namely acetyl acetone, malononitrile, ethyl cyanoacetate, cyanoacetamide and N-phenyl cyanoacetamide with 2,6-bis(2-methoxybenzylidene) cyclohexanone afforded chromene and quinoline derivatives in basic medium. The antitumor evaluation of some new compounds against three human cell lines, namely MCF-7, NCI-H460 and SF-268 showed significant and moderate activity compared with the positive control doxorubicin.

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.

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 Intramolecular Cyclization of N-acyl- and N-allyl-N ‘-(2-oxo-1,2-dihydro-pyridin-3-yl)thiourea

The reaction of 3-amino-4,6-dimethylpyridin-2(1H)-one and 3-amino-4-phenylpyridin-2-one with acyl isothiocyanates (benzoyl-, 4-bromobenzoyl-, and methacryloyl isothiocyanates) and with allyl isothiocyanate has been studied. The N-carbamothioyl methacrylamides and N-allylthioureas obtained undergo intramolecular heterocyclization reactions to give the corresponding 1,3-thiazin-4-one and 1,3-thiazoline derivatives. It was found that the starting 3-amino-4,6-dimethylpyridin-2(1H)-one shows antiradical activity but the synthesized thioureas do not.

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.

Synthesis and structure activity relationship of 1, 3-benzo-thiazine-2-thiones as selective HDAC8 inhibitors

Human histone deacetylase 8 (HDAC8) is a highly promising target for neuroblastoma and other types of cancer. Several HDAC inhibitors are approved for the treatment of special cancer subtypes or are evaluated in clinical trials. By far the most drugs or drug candidates contain a hydroxamate group that chelates the catalytic zinc ion within HDACs. Most hydroxamate inhibitors are more or less unselective, although there are considerable exceptions demonstrating the general feasibility to develop at least HDAC isoenzyme selective inhibitors. In addition, hydroxamates have recently come under discussion regarding their potential for mutagenicity. Recently, PD-404,182 was discovered as a selective and potent non-hydroxamate inhibitor of HDAC8. However, this active compound turned out to be decomposed in the presence of glutathion (GSH). Here, we describe the synthesis of significantly improved analogs of PD-404,182 that demonstrate both, great selectivity for HDAC8 and also chemical stability in the presence of GSH. The compounds are characterized with respect to structure-activity relationship, binding mode and target engagement in neuroblastoma cells by combining biochemical and biophysical methods with chemoinformatics.
