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.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5326-23-8, you can contact me at any time and look forward to more communication. Formula: C6H4ClNO2.

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.

In Vitro Antiproliferative Evaluation of Synthetic Meroterpenes Inspired by Marine Natural Products

Several marine natural linear prenylquinones/hydroquinones have been identified as anticancer and antimutagenic agents. Structure-activity relationship studies on natural compounds and their synthetic analogs demonstrated that these effects depend on the length of the prenyl side chain and on the type and position of the substituent groups in the quinone moiety. Aiming to broaden the knowledge of the underlying mechanism of the antiproliferative effect of these prenylated compounds, herein we report the synthesis of two quinones 4 and 5 and of their corresponding dioxothiazine fused quinones 6 and 7 inspired to the marine natural product aplidinone A (1), a geranylquinone featuring the 1,1-dioxo-1,4-thiazine ring isolated from the ascidian Aplidium conicum. The potential effects on viability and proliferation in three different human cancer cell lines, breast adenocarcinoma (MCF-7), pancreas adenocarcinoma (Bx-PC3) and bone osteosarcoma (MG-63), were investigated. The methoxylated geranylquinone 5 exerted the highest antiproliferative effect exhibiting a comparable toxicity in all three cell lines analyzed. Interestingly, a deeper investigation has highlighted a cytostatic effect of quinone 5 referable to a G0/G1 cell-cycle arrest in BxPC-3 cells after 24 h treatment.

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.

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.
