2,1-Benzothiazine 2,2-Dioxides. 5. Hydrolysis of Alkyl 1-R-4-Hydroxy-2,2-Dioxo-1H-2 lambda(6),1-Benzo-Thiazine-3-Carboxylates

Hydrolysis of 1-R-4-hydroxy-2,2-dioxo-1De-2 lambda(6),1-benzothiazine-3-carboxylate esters in HCl-AcOH-H2O mixture at 60A degrees D was accompanied by decarboxylation and led to 1-R-4-oxo-3,4-dihydro-1H-2 lambda(6),1-benzo-thiazine-2,2-diones. In the alkaline medium, regardless of the type of the substituent at position 1, analogous structural transformations occurred at first, but the thiazine ring was also destroyed along with the ester fragment when performing the reaction for a longer time.

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.

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.

Halocyclizations of Unsaturated Sulfoximines

A method for halocyclizations of S-alkenylsulfoximines is reported. When unsaturated NH-sulfoximines are treated with a combination of iodobenzene diacetate and potassium iodide, a transformation to the corresponding five- and six-membered cyclic products occurs providing S-oxides of dihydro isothiazoles and tetrahydro-1,2-thiazines, respectively, in moderate to high yields with good diastereoselectivities and excellent regioselectivities.

Tuning the Electronic Structure of Fe(II) Polypyridines via Donor Atom and Ligand Scaffold Modifications: A Computational Study

Fe(II) polypyridines are an important class of pseudo-octahedral metal complexes known for their potential applications in molecular electronic switches, data storage and display devices, sensors, and dye-sensitized solar cells. Fe(II) polypyridines have a d(6) electronic configuration and pseudo-octahedral geometry and can therefore possess either a high-spin (quintet) or a low-spin (singlet) ground state. In this study, we investigate a series of complexes based on [Fe(tpy)(2)](2+) (tpy = 2,2′;6′,2 ”-terpyridine) and [Fe(dcpp)(2)](2+) (dcpp = 2,6-bis(2-carboxypyridyl)pyridine). The ligand field strength in these complexes is systematically tuned by replacing the central pyridine with five-membered (N-heterocyclic carbene, pyrrole, furan) or six-membered (aryl, thiazine-1,1-dioxide, 4-pyrone) moieties. To determine the impact of ligand substitutions on the relative energies of metal-centered states, the singlet, triplet, and quintet states of the Fe(II) complexes were optimized in water (PCM) using density functional theory at the B3LYP+D2 level with 6-311G* (nonmetals) and SDD (Fe) basis sets. It was found that the dcpp ligand scaffold allows for a more ideal octahedral coordination environment in comparison to the tpy ligand scaffold. The presence of six-membered central rings also allows for a more ideally octahedral coordination environment relative to five-membered central rings, regardless of the ligand scaffold. We find that the ligand field strength in the Fe(II) polypyridines can be tuned by altering the donor atom identity, with C donor atoms providing the strongest ligand field.

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.
