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.

Synthesis of Benzo[1,4]thiazines via Ring Expansion of 2-Aminobenzothiazoles with Terminal Alkynes Under Metal-Organic Framework Catalysis

Copper-organic framework Cu-MOF-74 was synthesized, and consequently utilized as a heterogeneous catalyst for the synthesis of benzo[1,4]thiazines via ring expansion of 2-aminobenzothiazoles with terminal alkynes. Different from previous works, the reaction proceeded readily in the presence of lower catalyst concentration, at lower temperature, and under ligand-free conditions. The combination of 5 mol% framework catalyst, 20 mol% Cs2CO3, and 3 equivalents of di-tert-butyl peroxide led to high yields of benzo[1,4]thiazines. This copper-based framework demonstrated higher catalytic efficiency than a series of MOF-based heterogeneous catalysts and traditional homogeneous catalysts. In this system, the donation of soluble active copper species to the formation of benzo[1,4]thiazines was trivial. The copper-organic framework was reutilized without a remarkable decline in catalytic efficiency. To our best knowledge, this ring expansion reaction was not previously performed with a recyclable catalyst. [GRAPHICS] .

Selective Construction of Diverse Polycyclic Spirooxindoles via a Three-Component Reaction of Cyclic Mercapto-Substituted beta-Enamino Esters, Isatins, and Cyclic 1,3-Diketones

The three-component reaction of alkyl 2-(benzo[b][1,4]thiazin-3-ylidene)acetates, isatins, and 1,3-indanedione (1,3-cyclopentanedione) in ethanol in the presence of acetic acid conveniently afforded spiro[indeno[1,2-b]phenothiazine-6,3′-indolines] or spiro[cyclopenta[b]phenothiazine-4,3′-indolines] in good yields and with high diastereoselectivity. More interestingly, a similar three-component reaction with 4-hydroxychromen-2-one resulted in the unexpected polycyclic spiro[benzo[b]chromeno[3′,4′:5,6]-pyrano[2,3-e][1,4]thiazine-7,3′-indolines] in satisfactory yields. A plausible reaction mechanism was rationally proposed for formation of different kinds of the spiro compounds, and the stereochemistries of the various spiro compounds were clearly elucidated.

Azide based routes to tetrazolo and oxadiazolo derivatives of pyrrolobenzodiazepines and pyrrolobenzothiadiazepines

Tetrazolo- and 1,2,4-oxadiazolo-fused derivatives of the antitumour, antibiotic, DNA-interactive pyrrolo [2,1-c][1,4]benzodiazepines and their pyrrolobenzothiadiazepine derivatives have been produced as analogues of a 1,2,3-triazolo-fused pyrrolobenzothiadiazepine, which was shown to be a Glut-1 transporter inhibitor with potential as an antitumour agent. The tetrazolo-fused systems were produced by intramolecular 1,3-dipolar cycloaddition between an azide and a nitrile. The 1,2,4-oxadiazolo systems were produced by nitrile oxide cycloadditions to pyrrolobenzothiadiazepines, which were in turn produced from a 2-(azidobenzenesulfonyl)-1,2-thiazine 1-oxide. The latter species underwent a phosphite-mediated one-pot sulfur-extrusion, ring-contraction and azide to amine conversion to form 1-(amino-benzenesulfonyl)pyrroles. Bischler-Napieralski ring closure gave the pyrrolobenzothiadiazepines. (C) 2014 Elsevier Ltd. All rights reserved.

The corrosion inhibition of carbon steel in a 1.0 M HCl solution, using 4-amino-2-(4-chlorophenyl)-8-(2,3-dimethoxyphenyl)-6-oxo-2,6-dihydropyrimido[2, 1b][1,3] thiazine-3,7-dicarbonitrile (ACMPT) was investigated by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and quantum chemical calculations. Polarization curves indicate that the studied compound was acting as a mixed inhibitor with predominant cathodic effectiveness. The inhibition efficiency decreased with an increased temperature, and the thermodynamic and activation parameters obtained from this study were discussed. The adsorption behavior of ACMT follows Langmuir’s isotherm. In addition, Density Function Theory (DFT) calculations were performed on the studied molecule. The theoretical parameters obtained from this method are in good agreement with the experimental results.

SERS Spectroscopy and DFT Studies of Thionine and its Derivatives Adsorbed on Silver Colloids: Which N Atom is Used for Coordination of a Phenothiazine-Based Natural Dye to Electron-Deficient Metal Surface?

A Surface-enhanced Raman scattering (SERS) investigation has been carried out for thionine and its derivatives, well known blue-based dyes sharing the phenothiazine core. The thionine SERS spectrum is similar to its Raman spectrum. This suggests that the strong Raman bands mostly arising from in-plane ring modes are also enhanced on metal surface. Several originally weak Raman bands arising from the CNC moiety or H atoms on the thiazine N side also largely strengthen in the SERS spectrum. Density functional theory results for the plausible coordinated structures of thionine and the silver adatom reveal that coordination via the thiazine N atom to Ag+ leads to the most stable structure, and its calculated spectrum also best reproduces the SERS spectrum. The thionine derivatives show surprisingly analogous spectra, reflecting that the derivatives coordinate in a similar fashion to the metal surface. The high preference of the thiazine N atom for coordination is traced to the positive charge on the S atom.

Microwave-Assisted Synthesis of 2-Substituted 2-Thiazolines and 5,6-Dihydro-4 H -1,3-thiazines

An efficient and general method for the synthesis of 2-substituted thiazolines and 5,6-dihydro-4 H -1,3-thiazines is developed via microwave-assisted ring closure of omega -thioamidoalcohols promoted by ethyl polyphosphate (PPE). The cyclization reaction involves an S (N) 2-type mechanism and features the advantages of very short reaction times, high yields and a predictable stereochemical outcome. The acyclic precursors are prepared in high overall yields by an improved diacylation-thionation-saponification sequence from commercially available omega -aminoalcohols. The whole process is metal-free and operationally simple.
