Enhancement of nonlinear optical response of methylene blue and azure a during association with colloidal CdS quantum dots

The nonlinear optical response of thiazine dyes during association with colloidal CdS quantum dots (QDs) applying the z-scan technique at wavelength of 532 nm with use 10 ns pulses of Nd:YAG laser second harmonic were studied. Increasing in nonlinear absorption intensity in hybrid associates in comparison with the initial components were found. Moreover, UV-vis absorption spectrum shows the effective formation of dyes H-aggregates during association with colloidal QDs. Two-photon mechanism of observed nonlinear absorption in hybrid associates is proposed, based on a sharper dependence of the normalized transmittance on the incident intensity (distance between the sample and focal plane of focusing lens). And for pure solutions, the reverse saturated absorption is preferred nonlinear absorption mechanism. The nonlinear absorption coefficients for MB and AzA in the hybrid associates were found. They are beta approximate to 8.4 x 10(-9) cm W-1 (sic) approximate to 1.34 x 10(-8) cm W-1, respectively. It was shown that it is possible to control the parameters of nonlinear absorption of thiazine dyes via the hybrid association.

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.

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.

Therapeutic effects of an azaphenothiazine derivative in mouse experimental colitis

Phenothiazines represent a class of compounds of potential therapeutic utility. In this report we evaluated therapeutic value of an azaphenothiazine derivative, 6-acetylaminobutyl-9-chloroquino[3,2-b]benzo[1,4]thiazine (QBT), given intragastrically, in the model of dextran sodium sulfate-induced colitis in C57BL/6 mice using 5-aminosalicylic acid (5-ASA) as a reference drug. Colitis symptoms such as body weight loss, diarrhea and hematochezia (blood in stool) were observed and registered and disease activity index (DAI) was calculated. In addition, weight and cell numbers in the lymphatic organs and histological parameters of the colon wall were analyzed. The effects of QBT on viability of colon epithelial cell lines were also determined. We showed that weight and cell number of draining mesenteric lymph nodes were lower in mice treated with QBT in comparison to their control counterparts. The number of thymocytes, drastically reduced in control mice, was elevated in mice treated with the compounds with a significant effect of 5-ASA. In addition, an abnormal composition of blood cell types was partially corrected in these groups. Histological analysis of the colon revealed that the pathological changes were partially normalized by QBT and even to a higher degree by 5-ASA. In conclusion we demonstrated a therapeutic efficacy of the compound in amelioration of local and systemic pathological changes associated with chemically-induced colitis in mice. A possible mechanism of action of the compound is discussed.

Synthesis and Investigation of Pinane-Based Chiral Tridentate Ligands in the Asymmetric Addition of Diethylzinc to Aldehydes

A library of pinane-based chiral aminodiols, derived from natural (-)-beta-pinene, were prepared and applied as chiral catalysts in the addition of diethylzinc to aldehydes. (-)-beta-Pinene was reacted to provide 3-methylenenopinone, followed by a reduction of the carbonyl function to give a key allylic alcohol intermediate. Stereoselective epoxidation of the latter and subsequent ring opening of the resulting oxirane with primary and secondary amines afforded aminodiols. The regioselectivity of the ring closure of the N-substituted secondary aminodiols with formaldehyde was examined and exclusive formation of oxazolidines was observed. Treatment of the allylic alcohol with benzyl bromide provided the corresponding O-benzyl derivative, which was transformed into O-benzyl aminodiols by aminolysis. Ring closure of the N-isopropyl aminodiol derivative with formaldehyde resulted in spirooxazolidine. The obtained potential catalysts were applied in the reaction of both aromatic and aliphatic aldehydes to diethylzinc providing moderate to good enantioselectivities (up to 87% ee). Through the use of molecular modeling at an ab initio level, this phenomenon was interpreted in terms of competing reaction pathways. Molecular modeling at the RHF/LANL2DZ level of theory was successfully applied for interpretation of the stereochemical outcome of the reactions leading to display excellent (R) enantioselectivity in the examined transformation.

Microwave-assisted Solid-phase Synthesis of N-substituted-2-aminobenzo[d][1,3] Thiazine Derivatives from a BOMBA Resin

An efficient solid-phase methodology has been developed for the synthesis of N-acyl and N-sulfonyl substituted 2-aminobenzo[d][1,3] thiazine derivatives. The key step in this methodology is the preparation of backbone amide linker-bound 2-aminobenzo[d][1,3] thiazine resin through cyclization reaction between isothiocyanates and BOMBA resin under microwave irradiation. This 2-aminobenzo[d][1,3] thiazine core skeleton resin undergoes substitution reactions with various electrophiles, such as acid halides and sulfonyl halides, to generate N-acyl and N-sulfonyl substituted 2-aminobenzo[d][1,3] thiazine resins, respectively. Finally, N-acyl and N-sulfonyl-substituted 2-aminobenzo[d][1,3] thiazine derivatives are prepared in good yields and purities by cleavage of the respective resins under trifluoroacetic acid (TFA) in dichloromethane (DCM).

Biosorption of six basic and acidic dyes on brown alga Sargassum ilicifolium: optimization, kinetic and isotherm studies

Biosorption of Methyl Blue (MB), Fuchsin Acid (FA), Rhodamine B (RB), Methylene Blue (MEB), Bromocresol purple (BC) and Methyl Orange (MO) onto Sargassum ilicifolium was studied in a batch system. Effect of dye structure on biosorption by Sargassum ilicifolium was studied to define the correlation between chemical structure and biosorption capacity. Different dye groups such as triarylmethane (MB, FA and BC), monoazo (MO), thiazine (MEB) and xanthene (RB) were studied. At optimum experimental conditions for each dye, biosorption capacity was determined and compared. The results indicate that the chemical structure (triarylmethane, monoazo, thiazine, xanthene), number of sulfonic groups, basicity (element of chromophore group: S, N, O) and molecular weight of dye molecules influence their biosorption capacity. Experimental parameters such as biosorbent dose, pH, contact time, and initial dye concentration were optimized for each dye. The biosorption kinetic data were successfully described by the pseudo second-order model. The biosorption results were also analyzed by the Langmuir and Freundlich isotherms. Finally, biosorption capacities obtained using Sargassum ilicifolium were compared with the ones presented in the literature.
