Discovery of [1,2,4]Triazole Derivatives as New Metallo-beta-Lactamase Inhibitors

The emergence and spread of metallo-beta-lactamase (MBL)-mediated resistance to beta-lactam antibacterials has already threatened the global public health. A clinically useful MBL inhibitor that can reverse beta-lactam resistance has not been established yet. We here report a series of [1,2,4]triazole derivatives and analogs, which displayed inhibition to the clinically relevant subclass B1 (Verona integron-encoded MBL-2) VIM-2. 3-(4-Bromophenyl)-6,7-dihydro-5H-[1,2,4]triazolo [3,4-b][1,3]thiazine (5l) manifested the most potent inhibition with an IC50 (half-maximal inhibitory concentration) value of 38.36 mu M. Investigations of 5l against other B1 MBLs and the serine beta-lactamases (SBLs) revealed the selectivity to VIM-2. Molecular docking analyses suggested that 5l bound to the VIM-2 active site via the triazole involving zinc coordination and made hydrophobic interactions with the residues Phe61 and Tyr67 on the flexible L1 loop. This work provided new triazole-based MBL inhibitors and may aid efforts to develop new types of inhibitors combating MBL-mediated resistance.

Removal of some cationic dyes from aqueous solution by acrylamide- or 2-hydroxyethyl methacrylate-based copolymeric hydrogels

In this study, anionic hydrogels were prepared using a crosslinker (N,N’-methylenebisacrylamide) through a free radical addition reaction in aqueous solutions of neutral acrylamide or 2-hydroxyethyl methacrylate monomer and anionic monomers, mesaconic acid or aconitic acid. Cationic dyes along with safranine (azine-), nile blue (oxazine-) and methylene blue (thiazine-) were selected as models of pollutants, and adsorption of these dyes onto the hydrogels was investigated. To examine the effect of concentration on adsorption, dye solutions prepared with a concentration range of 5-50 mg l (-1) and 0.1 g hydrogel at 25 A degrees C were exposed to the hydrogels until equilibrium was established. Dye adsorption onto the hydrogels was found to be an L type Giles adsorption isotherm. Monolayer sorption capacity and adsorption constant values were calculated from the Langmuir plots. To calculate R-L values, a non-dimensional analysis was used and they were always found to be 0 < R < 1. In other words, the hydrogels were favorable for adsorption of these dyes. Aqueous solutions of dyes were observed to interact with hydrogels in the following order: oxazine > azine > thiazine. Furthermore, the higher the number of carboxyl groups in the hydrogel composition, the higher the adsorbed amount of substance.

Versatile one-pot synthesis of benzo-fused thiacycles by copper catalysis

A novel, one-pot synthesis of structurally diverse benzo-fused thiacycles via a Cu-catalysed intermolecular C-S coupling/cyclisation tandem process, employing the same catalytic system, has been developed. Thus, 3,4-dihydro-2H-benzo[e][1,3]thiazines and 4H-benzo[e][1,3] thiazines were selectively obtained by this one-pot tandem process from (2-iodophenyl) methanamine and aldehydes or 1-(azido-methyl)-2-iodobenzene, respectively. These reactions proceeded in toluene at 100 degrees C with potassium thioacetate, thiobenzoate or ethyl xanthogenate in moderate to good isolated yields. The first one avoids the imine isolation step. A similar approach to benzo[b] thiophene derivatives from 2-(2- iodophenyl) acetonitrile was also developed.

DECOLORIZATION KINETICS OF ACID AZO DYE AND BASIC THIAZINE DYE IN AQUEOUS SOLUTION BY UV/H2O2 AND UV/FENTON: EFFECTS OF OPERATIONAL PARAMETERS

The photochemical decolorization of two dyes, namely Acid Yellow 54 and Basic Blue 9, was studied using the UV/H2O2 and UV/Fenton processes. The effects of the amount of H2O2 and FeSO4 as well as the initial pH solution on decolorization kinetics of both the dyes were investigated. The pseudo-first order kinetic model was applied to predict the decolorization of the selected dyes at the different operational conditions and results showed that this model fitted very well with the experimental data. The obtained results also showed the efficiency of UV/Fenton process to quickly degrade aqueous effluents polluted by Acid Yellow 54 and Basic Blue 9 compared to the UV/H2O2 process.

Crystal structure of (1S, 2S, 5R)-5-acetylamino-4oxo-2,3-diphenyl-1,3-thiazinan-1-ium-1-olate

The asymmetric unit of the enantiomerically pure title compound, C18H18N2O3S, comprises two independent molecules (A and B) having almost identical conformations. When overlayed, the alignment-r. m. s. deviation value is 0.30 angstrom. The six-membered heterocycle has a twisted half-chair conformation in both molecules. The O atom on the S atom of the ring is pseudo-axial on the thiazine ring and trans to both a phenyl group substituent and the acetamide group in each case. The two benzene rings in each molecule are almost orthogonal to each other, with interplanar dihedral angles of 83.79 (17) and 86.95 (16)degrees. The acetamide group is pseudo-equatorial and a phenyl ring is pseudo-axial on the thiazine ring. Both molecules show a weak intramolecular C-H center dot center dot center dot O interaction between H-atom donors of one of the phenyl rings and the acetamide group. In the crystal, an intermolecular N-H center dot center dot center dot O( thiazine) hydrogen bond links B molecules along the 21 (b) screw axis and, in addition, an N-H center dot center dot center dot O( acetamide) hydrogen bond links A and B molecules across a. A two-dimensional layered structure lying parallel to (001) is generated, also involving weak intermolecular C-H center dot center dot center dot O interactions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 26978-64-3. Quality Control of 4-Hydroxybutane-1-sulfonic acid.

Resistant Hypertension: Questions and Contemporary Answers

The review presents the important problem of resistant hypertension. Its real prevalence is unknown. According to population studies and meta-analyzes of clinical studies, the prevalence of this most severe form of hypertension reaches 12-15% in the general population and 15-18% in clinical cohorts. Over the past decades, an increase in its frequency among patients with hypertension has been noted. Based on the results of large-scale studies, risk factors are detected that allow to assess the risk for the resistance to antihypertensive drugs. Adherence to ongoing antihypertensive therapy is crucial to addressing the issue of hypertension resistance; there are acceptable ways to evaluate it in clinical practice. The review discusses the most common mistakes in the choice of therapy, which can cause resistance to antihypertensive treatment, namely irrational drug combinations, insufficient dosage of the drug, and the use of non-prolonged forms of drugs. The latest recommendations for the diagnosis and treatment of hypertension, including its resistant form, are analyzed. The review contains a rationale based on the results of randomized clinical trials, the choice antihypertensive strategy in this variant of arterial hypertension. The importance of fixed combination antihypertensive drugs, as well as thiazine-like diuretics and amlodipine is stressed. The results of studies demonstrate the rational for the use of antimineral corticoid drugs, namely spironolactone, for this category of patients. The authors offer an updated algorithm for the diagnosis and treatment of resistant hypertension, based on the sections of the latest clinical recommendations on this problem.

6-Substituted 9-fluoroquino[3,2-b]benzo[1,4]thiazines display strong antiproliferative and antitumor properties

6-Substituted 9-fluoroquino[3,2-b]benzo[1,4]thiazines – a new type of tetracyclic azaphenothiazines -were obtained from of 6H-9-fluoroquinobenzothiazine by the introduction of appropriate substituents to the thiazine nitrogen atom (alkyl, aminoalkyl, amidoalkyl, sulfonamidoalkyl and nitrogen half-mustard groups). The compounds displayed differential cytotoxic as well as antiproliferative actions against human peripheral blood mononuclear cells (PBMC) stimulated with phytohemagglutinin A (PHA). In addition, they suppressed lipopolysaccharide (LPS)-induced tumor necrosis factor alpha (TNF-alpha) production by whole blood human cell cultures. Two compounds (4 and 15, with the propargyl and methanesulfonamidopropyl groups) were selected for further experiments because of lack of cytotoxicity and strong antiproliferative actions. Compound 4 showed strong suppressive actions on growth of L1210, SW948, A-431 and CX-1 tumor cell lines which were close to those of cisplatin, the reference drug (e.g. GI(50) of 2.28 mu g/mL vs. 1.86 mu g/mL for L1210 cells). Further, the compound appeared to be equally effective as cyclosporine A (CsA) in the inhibition of human two-way mixed lymphocyte reaction (MLR). The compound did not significantly inhibit interleukin 2 (IL-2)-induced growth of CTLL-2 cell line. In addition, inhibition of prostaglandin (PG) synthesis by indomethacin or block of PG receptors did not interfere with the inhibitory effect of the compound on PHA-induced cell proliferation. Therefore, it is likely that the compound acts by inhibiting cell cycle as proposed for other phenothiazines. Further studies are required for the elucidation of the mechanism of action and therapeutic utility of these compounds in more advanced in vivo models. (C) 2014 Elsevier Masson SAS.

Chaotropic Agents Boosting the Performance of Photoionic Cells

Photoionic cells are a simple and scalable concept for direct solar energy storage, where the redox fuels produced by the photoreaction are separated in different phases to prevent recombination. The presence of chaotropic agents such as urea, that break the structure of water, was found to drastically enhance the quantum yield; a 10-fold increase of quantum yield to over 13% was achieved by addition of chaotropes into a system based on the reductive quenching of Azure B by Co(II)EDTA in water and the extraction of the leuco dye in 1,2-dichloroethane.
