Halogenated phenotiazine as photoantimicrobial agent against Staphylococcus aureus. Evaluation of the vehiculization in polymeric nanoparticles

A thiazine derivative of AzB, the monoiodinated Azure B (AzBI), was designed, characterized, chemical and photochemically evaluated, and screened for antibacterial activity. The monoiodinated derivative showed better chemical and photochemical properties compared to the leading compound Azure B (AzB). Also, AzBI exhibited good antibacterial activity against methicillin-sensitive Staphylococcus aureus (MSSA) ATCC 29213 and methicillin-resistant S. aureus (MRSA) ATCC 43300. The assayed compound represents a promising structure for the development of a new synthetic photosensitizer with improved properties and biological activity. Based on the results obtained for AzBI, this compound was loaded in the polymeric nanoparticles synthesized by our working group in order to improve some of its physicochemical properties. In this way, it was possible to successfully load the monoiodinated derivative and yield a promising drug transport system. The latter presented better characteristics and antimicrobial activity than AzBI against the different strains tested. All these results make AzBI an excellent candidate for application in photodynamic therapy.

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.

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.

Experimental and Quantum Chemical Analysis of New Pyrimidothiazine Derivative as Corrosion Inhibitor for Mild Steel in 1.0 M Hydrochloric Acid Solution

The corrosion inhibition efficiency of pyrimidothiazine compound, namely: 8-ethyl-3-hydroxy-4,6-dioxo-2-(p-tolyl)-4,6-dihydropyrimido [2,1-b][1,3] thiazine-7carbonitrile (EHDPTC), was evaluated in the system steel/1 M HCl. This compound is investigated experimentally using weight loss, potentiodynamic polarization curves and electrochemical impedance spectroscopy. The results showed that the inhibition mechanism involves blockage of the steel surface by the inhibitor molecules by a Langmuir-type adsorption process and that the structure of molecule plays an important role in the inhibition efficiency of the synthesized inhibitor.

Spectral Study on Association of Thiazine Dyes with Anionic Polymers

Feasible method of quantitative determination of anionic polymers in aqueous solutions was described using poly(styrene sulfonate) and poly(acrylate) sodium salts as an example. The method consists in absorbance measurements while titrating with thiazine dye. Volume of dye solution needed to attain specified value of absorbance is linearly dependent on polymer concentration. Optimal wavelengths are 666nm and 640nm for Methylene Blue dye and Toluidine Blue dye, respectively. Calibration plots are straight lines (r(2) > 0.99) ensuring good accuracy of the method developed. Range of measurable concentrations is dependent on chosen value of end-point absorbance.

Adsorptive removal of thiazine dyes from aqueous solutions by oil shale and its oil processing residues: Characterization, equilibrium, kinetics and modeling studies

Adsorption characteristics of oil shale (OS) and its pyrolysis byproducts for cationic thiazine dyes were investigated using thionine (TH), toluidine blue (TB) and methylene blue (MB). The time dependent data for the OS adsorption were analyzed using the linear driving force (LDF) model by combining with the Langmuir isotherm. The external mass transfer (k(f)) and surface diffusion (D-s) coefficients were analytically calculated based on McKay equation. They decreased with increasing molecular sizes of the dyes in the following order TH > TB > MB. In contrary, desorption efficiency in 0.1 M NaCI solution increased in the same order. The thermogravimetric analysis (TGA/DTG), atomic force microscopy (AFM), diffuse reflectance infrared Fourier transforms (DRIFT) and X-ray diffraction (XRD) spectroscopy techniques were used in conjunction to characterize the OS samples. A comparison of (DRIFT) spectra of the dye loaded and unloaded adsorbents showed that the larger dye molecules are primarily adsorbed on the negatively charged surface hydroxyl groups and/or on organic functional groups with electrostatic interactions while the smaller molecules replace with structural cations in the interlayer space of the mineral matrices. Adsorption capacity of the pyrolysis residue obtained in nitrogen atmosphere at 200 degrees C (OS-200) for the dyes decreased with respect to the OS whereas the byproduct at 500 degrees C (OS-500) had considerably higher adsorption ability. All of the dyes were completely removed by the OS and OS-500 from dilute solutions (<0.5 mmol L-1). The OS-500 was also a good candidate for water remediation due to its high dye removal capacity in concentrated dye solutions. (C) 2015 Elsevier B.V. All rights reserved.

1,3-Thiazine, 1,2,3,4-Dithiadiazole, and Thiohydrazide Derivatives Affect Lipid Bilayer Properties and Ion-Permeable Pores Induced by Antifungals

Over the past decade, thiazines, thiadiazoles, and thiohydrazides have attracted increasing attention due to their sedative, antimicrobial, antiviral, antifungal, and antitumor activities. The clinical efficacy of such drugs, as well as the possibility of developing resistance to antimicrobials, will depend on addressing a number of fundamental problems, including the role of membrane lipids during their interaction with plasma membranes. The effects of the eight 1,3- thiazine-, 1,2,3,4- dithiadiazole-, and thiohydrazide-related compounds on the physical properties of model lipid membranes and the effects on reconstituted ion channels induced by the polyene macrolide antimycotic nystatin and antifungal cyclic lipopeptides syringomycin E and fengycin were observed. We found that among the tested agents, the fluorine-containing compoundN ‘-(3,5-difluorophenyl)-benzenecarbothiohydrazide (C6) was the most effective at increasing the electric barrier for anion permeation into the hydrophobic region of the membrane and reducing the conductance of anion-permeable syringomycin pores. A decrease in the membrane boundary potential with C6 adsorption also facilitated the immersion of positively charged syringomycin molecules into the lipid bilayer and increases the pore-forming ability of the lipopeptide. Using differential scanning microcalorimetry, we showed that C6 led to disordering of membrane lipids, possibly by potentiating positive curvature stress. Therefore, we used C6 as an agonist of antifungals forming the pores that are sensitive to membrane curvature stress and lipid packing, i.e., nystatin and fengycin. The dramatic increase in transmembrane current induced by syringomycin E, nystatin, and fengycin upon C6 treatment suggests its potential in combination therapy for treating invasive fungal infections.

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.
