Inhibition of heat shock protein (Hsp) 90 potentiates the antiproliferative and pro-apoptotic effects of 2-(4 ‘ fluoro-phenylamino)-4H-1,3-thiazine[6,5-b]indole in A2780cis cells

Ovarian carcinoma is initially sensitive to platinum-based therapy, but become resistant over time. The study of cancer sensitizing substance is therefore the major challenge for a number of scientific groups. Our experiments were carried out on human ovarian adenocarcinoma A2780cis cells resistant to cisplatin and their response to 2-(4’fluoro-phenylamino)-4H-1,3-thiazine[6,5-b] indole (thiazine[6,5-b] indole) and/or heat shock protein (Hsp) 90 inhibitor 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) using proliferation assay, cell cycle analysis and monitoring of apoptosis were examined. A2780cis cells revealed the same fold of resistance to Hsp90 inhibitor 17-DMAG as it is declared for cisplatin (18 times), but only 3.2 times for thiazine[6,5-b] indole. Our results showed that the combination of thiazine[6,5-b] indole and 17-DMAG significantly reduced proliferation of A2780cis cells and led to their accumulation in G2/M phase of the cell cycle. Moreover, both thiazine[6,5-b] indole as well as 17-DMAG increased the number of annexin V positive A2780cis cells in time dependent manner. Interestingly, thiazine[6,5-b] indole treatment significantly activated also caspase-3 compared to untreated or 17-DMAG-treated cells and reduced mitochondrial membrane potential (MMP) of A2780cis cells with more significant decline after combined treatment. In this regard, the incubation of A2780cis cells with thiazine[6,5-b] indole induced PARP protein cleavage as well as an increased level of Bad protein with more pronounced changes after combined treatment. Importantly, Hsp70 protein was not upregulated in A2780cis cells neither by individual treatment nor by mutual combination. Our results signify antiproliferative and pro-apoptotic effects of novel thiazine[6,5-b] indole potentiated by Hsp90 inhibitor 17-DMAG in ovarian adenocarcinoma cells resistant to cisplatin and therefore represents new strategy in cancer treatment.

Removal of Synthetic Dyes by Dried Biomass of Freshwater Moss Vesicularia Dubyana: A Batch Biosorption Study

In this work the biosorption of cationic dyes thioflavin T (TT) and methylene blue (MB) from single and binary solutions on dried biomass of freshwater moss Vesicularia dubyana as a function of contact time, pH, and biomass or sorbate concentration has been investigated. The prediction of maximum sorption capacities using adsorption isotherm models were also realized. Biosorption of TT and MB is a rapid process strongly affected by solution pH. Maximum sorption capacities Q(max) calculated from Langmuir isotherm were 119 +/- 11 mg/g for TT and 229 +/- 9 mg/g for MB. In binary mixture, the presence of MB caused significant decrease of TT sorption, advocating the competitive sorption between TT and MB. Results revealed that V. dubyana biomass exhibited significantly higher affinity to thiazine dye MB in comparison with benzothiazole dye TT from both single and binary solutions. Based on the obtained results, the competitive effects in binary system can substantially influence the sorption process and should be thoroughly evaluated before application of selected adsorbents for removal of basic dyes from colored effluents.

Synthesis, crystal structure, antioxidant activity and dft study of 2-aryl-2,3-dihydro-4H-[1,3]thiazino[3,2-a]benzimidazol-4-One

The compound 2-aryl-2,3-dihydro-4H- [1,3]thiazino[3,2-a]benzimidazol-4-one (C16H12N2OS) (III) was synthesized. The compound crystallized in a monoclinic crystal system with P2(1)/c space group as revealed by mono-crystal X-ray diffraction. The X-ray analysis and density functional theory complementary calculations showed that noncovalent C-H center dot center dot center dot pi interactions between the benzimidazole system and the thiazine ring form a dimerization along the direction of the b axes, additionally pi center dot center dot center dot pi interactions were found between the benzene rings. The C12, in the thiazine ring, has a distortion angle (41.69 degrees) respect to the plane of benzimidazole. The intermolecular interactions in the crystal structure were quantified and analyzed using Hirshfeld surface analysis. The predominant interaction within the crystalline structure was found to be H center dot center dot center dot H interaction. On the other hand, antioxidant activity of the C16H12N2OS system was studied using the DPPH center dot and ABTS center dot(+) assay. Using the energy profile for the reaction of DPPH center dot with III it was demonstrated that the antioxidant activity is carried out through HAT (H12) mechanism where conjugation of the radical can occur between the C12 of the thiazine ring and the aromatic ring, this was confirmed by a H function calculation. The importance of this study focuses on the promising range of biological activities and molecular characteristics of the synthesized compound (III). (C) 2019 Elsevier B.V. All rights reserved.

Assessment of a pretomanid analogue library for African trypanosomiasis: Hit-to-lead studies on 6-substituted 2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3] thiazine 8-oxides

A 900 compound nitroimidazole-based library derived from our pretomanid backup program with TB Alliance was screened for utility against human African trypanosomiasis (HAT) by the Drugs for Neglected Diseases initiative. Potent hits included 2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3] thiazine 8-oxides, which surprisingly displayed good metabolic stability and excellent cell permeability. Following comprehensive mouse pharmacokinetic assessments on four hits and determination of the most active chiral form, a thiazine oxide counterpart of pretomanid (24) was identified as the best lead. With once daily oral dosing, this compound delivered complete cures in an acute infection mouse model of HAT and increased survival times in a stage 2 model, implying the need for more prolonged CNS exposure. In preliminary SAR findings, antitrypanosomal activity was reduced by removal of the benzylic methylene but enhanced through a phenylpyridine-based side chain, providing important direction for future studies (C) 2017 Elsevier Ltd.

Synthesis, Cytotoxicity Evaluation, Molecular Docking and Utility of Novel Chalcones as Precursors for Heterocycles Incorporating Pyrazole Moiety

Background: Chalcones, 2-pyrazolines and thiazoles have been reported to possess various pharmacological activities. Objective: Synthesis of new chalcones and utilizing them as a building block for constructing a series of thiazole derivatives and evaluating some of them as anticancer agents. Method: The new compounds were synthesized via stirring at room temperature or thermal heating. Cytotoxic evaluation of the new synthesized compounds was tested using the method of Skehan et al. Moreover, the computational studies were performed using MOE 2014.09 software. Result: A series of new chalcones were prepared by the reaction of ethyl 3-acetyl-1-aryl-5-methyl-1H-pyrazole-4-carboxylate with a number of substituted benzaldehydes. One of these chalcones was used as a building block for constructing a pyrazoline ring via its reaction with thiosemicarbazide. The produced carbothioamide derivative was used for the preparation of two series of thiazole derivatives by its reaction with a number of hydrazonoyl chlorides. Moreover, reaction of 3-acetylpyrazole thiosemicarbazone derivative with a number of N-aryl-2-oxopropane hydrazonoyl chlorides afforded 5-arylazothiazole derivatives. The assigned structures for all the newly synthesized compounds were confirmed on the basis of elemental analyses and spectral data. Some of the newly synthesized chalcones and thiazoles were tested for their cytotoxicity against human colon carcinoma cell line (HCT-116) and the molecular docking was carried out on the most active compound 3f. Conclusion: The results of the anticancer activity revealed that compounds 3f, 3e, 3c and 3b have promising activities compared with the standard drug Doxorubicin. Moreover, the computational studies confirm the results of biological activity. Also, the ADME profile study showed that compound 3f can be considered as a promising drug by conducting good pharmacokinetic and medicinal chemistry tests.

Characterization of biogenically synthesized silver nanoparticles for therapeutic applications and enzyme nanocomplex generation

The present study describes green synthesis of silver nanoparticles (AgNPs) and inulin hydrolyzing enzyme nanocomplexes (ENC) usingAzadirachta indica(Ai) andPunica granatum(Pg) leaf extracts. Surface topology and physico-chemical characteristics of AgNPs were studied using surface plasmon resonance (SPR), FTIR, SEM, AFM and EDX analyses. Particle size analysis using dynamic light scattering and AFM studies revealed thatAi-AgNPs (76.4 nm) were spherical in shape having central bigger nano-regime with smaller surroundings whilePg-AgNPs (72.1 nm) and ENCs (Inulinase-Pg-AgNPs similar to 145 nm) were spherical particles having smooth surfaces.Pg-AgNPs exhibited significant photocatalysis of a thiazine dye, methylene blue. BothAi-andPg-AgNPs showed selective antibacterial action by inhibiting pathogenicBacillus cereus, while the probioticLactobacillusstrains remained unaffected.Ai-AgNPs showed potential anti-biofilm effect (30% viability) onB. cereusbiofilms.Pg-AgNPs showed anti-cancer effect against human colon cancer cell lines (Caco-2) resulting in 40% cell death in 48 h. Enzymes (inulinase, L-asparaginase and glucose oxidase) were successfully immobilized onto nanoparticles together with the biogenic synthesis of AgNPs and recyclability of the Inulinase-Pg-AgNPs complex was demonstrated. The study elaborates characteristics of green synthesized nanoparticles and their potential applications as anti-cancer, antibacterial and antioxidant nano drugs that could be used in food and nutraceutical industries. Enzyme immobilization on AgNPs without any toxic cross-linker opens up newer possibilites in enzyme-nanocomplex research.

Potentiometric and Theoretical Studies of (2Z, 3Z)-2H-benzo[b][1,4]thiazine-2,3(4H)-dionedioxime with Some Divalent Transition Metal Ions

The protonation equilibria of (2Z, 3Z)-2H-benzo[b][1,4]thiazine-2,3(4H)-dionedioxime (BTDH2) together with the equilibria of its bis- binary complexes of Co(II), Ni(II), Cu(II) and Zn(II) were investigated potentiometrically. The investigation was carried out at 25 +/- 0.1 degrees C, in aqueous solution, with a constant ionic strength of 0.100 mol.dm(-3) NaCl. The protonation constants of the ligand together with the stability constants of a variety of complexes were determined potentiometrically in 10 % ethanol-water mixed solution using the SUPERQUAD computer program. Theoretical calculations were set up to assist in understanding the protonation sequence in the ligand molecule via the semi-empirical molecule orbital method of parameterized model number 3. Results are discussed in connection to the basicity of the donor atoms and structural arrangement of the ligand. Although BTDH2 has two dissociable protons, four protonation constants can be measured under the experimental conditions presented. These four protonation constants (as log(10) beta s) are 10.245, 19.397, 22.414 and 25.176.
