Crystal Structure of Ethyl 2,4-Dimethyl-1-phenyl-6-thioxo-1,6-dihydropyrimidine-5-carboxylate: The Product from the Reaction of Ethyl 3-Aminocrotonate, Phenylisothiocyanate and Acetic Anhydride

The crystal structure of ethyl 2,4-dimethyl-1-phenyl-6-thioxo-1,6-dihydropyrimidine-5-carboxylate (7) has been determined (monoclinic, P2(1)/n, a 12.5543(9); b 7.6345(4); c 16.1568(14) , beta 107.210(9)A degrees) revealing a thioamide functional group instead of the thiazine ethyl (Z)-2,4-dimethyl-6-(phenylimino)-6H-1,3-thiazine-5-carboxylate (5) proposed previously. This has required the revision of the published structure for this multicomponent reaction which now has identified (7), not (5), as the product, supported by NMR and IR analysis. The crystal structure of the major product from the reaction of ethyl 3-aminocrotonate, phenylisothiocyanate and acetic anhydride is ethyl 2,4-dimethyl-1-phenyl-6-thioxo-1,6-dihydropyrimidine-5-carboxylate (shown), not the previously identified ethyl (Z)-2,4-dimethyl-6-(phenylimino)-6H-1,3-thiazine-5-carboxylate.

Accurate studies on the effect of substituents on the crystal packing are essential for understanding the intermolecular interactions and thus paving the way to crystal structure prediction. The crystal structures of diethyl 1-(4-chlorobenzyl)4-(4-chlorophenyl)-2,2-dioxo-3,4,6,7,8,8a-hexahydro-1H-pyrrolo[2,1-c][1,4]thiazine-1,3-dicarboxylate, C26H29Cl2NO6S, (I), and its isomorphous pair diethyl 1-(4-methylbenzyl)-4-(4-methylphenyl)-2,2-dioxo-3,4,6,7,8,8a-hexahydro-1H-pyrrolo[2,1-c][1,4]thiazine-1,3-dicarboxylate, C28H35NO6S, (II), are described. The molecular aggregation patterns appear to be strikingly similar despite changes in the substituents, with a Cl atom in (I) being replaced by a methyl group in (II). Inspite of the chemical modifications, the structures of (I) and (I) are isomorphous, isostructural and found to obey the chlorine-methyl exchange rule. Both the structures feature C-H center dot center dot center dot O hydrogen bonding. However, a distinguishing feature between (I) and (II) is observed in the conformation of the pyrrole rings where the twist occurs on different C-N bonds. Hirshfeld analysis of both structures is presented and discussed.

Lipophilicity estimation of anti-proliferative and anti-inflammatory 6-substituted 9-fluoroquino[3,2-b]benzo[1,4]thiazines

The lipophilicity parameters (logP(calcd), R-M0 and logP(TLC)) of 17 new anti-proliferative and anti-inflammatory tetracyclic 6-substituted 9-fluoroquinobenzothiazines were determined theoretically using computational methods and experimentally by reversed-phase thin-layer chromatography. The experimental parameter R-M0 was determined on the RP-18 silica plates with acetone-aqueous TRIS buffer as mobile phase. The obtained parameter R-M0 was further transformed into parameter logP(TLC) by use of the calibration curve. The theoretical logP(calcd) values differed depending on the substituents and nature of calculating programs. Fluoroquinobenzothiazines turned out to be rather middling or highly lipophilic compounds. The parameter R-M0 and specific hydrophobic surface area b were meaningly intercorrelated showing congeneric two classes of quinobenzothiazines. The calculated logP(calcd) and experimental logP(TLC) values were compared and intercorrelated to show different prediction power of the computational programs. The lipophilicity was correlated with molecular descriptors (molar mass, molar volume, and molar refractivity), biomolecular descriptors (HIA, PB, MDCK, Caco-2, and BBB) and in vitro tested biological activities (tumor necrosis factor alpha inhibition and antiproliferative activity).

The Smiles rearrangement in the syntheses of azaphenothiazines. Part II. The review of the various types of phenyl azinyl and diazinyl sulfides undergoing this rearrangement

Azaphenothiazines are one of the most bioactive heterocyclic scaffolds in medicinal chemistry. This review discusses the Smiles rearrangement of over 40 types of phenyl azinyl sulfides and diazinyl sulfides during syntheses of azaphenothiazines. These syntheses consist of two (rearrangement/cyclization) or three steps (sulfide formation/rearrangement/cyclization) proceeding often rapidly without isolation of intermediates. The rearrangement depends on the nature of sulfides, steric hindrance, reaction conditions (basic, but also weakly and strongly acidic, and even neutral and thermal). Some reaction conditions and catalysts favor direct cyclization. This review arranges the knowledge of the Smiles rearrangement of phenyl azinyl and diazinyl sulfides but also systematizes the syntheses of monoaza-, diaza-, triaza-, tetraazaphenothiazines and their benzo- and dibenzo derivatives. The review shows that some formed azaphenothiazines were wrongly identified and not all wrong structures have been corrected. Some syntheses cannot be defined as proceeding with the rearrangement or not when both the rearranged and direct products are the same. The structure analysis of resulted azaphenothiazines is crucial (the most reliable: X-ray analysis or two-dimensional NMR). The authors hope that this review will prompt researchers to revisit some syntheses of azaphenothiazines. (C) 2020 Elsevier B.V. All rights reserved.

A comparative study of media polarity effects on the linear and third-order nonlinear optical responses of thiazine dyes

In this paper, solvent effects on the linear and nonlinear optical responses of thiazine dyes were investigated. Spectroscopic and open aperture Z-scan techniques were used for studying linear and nonlinear responses of azure A and methylene blue dyes. The experimental results show that linear and nonlinear optical properties of used dyes depend highly on the molecular structure and their surrounding media characteristics. The calculated contribution of various media-induced interactions indicate that solvent hydrogen bond acceptor and solvent dipolarity and polarizability abilities have significant effects on the linear and nonlinear absorption characteristics of thiazine dyes. Moreover, by transition of the linear optics domain to nonlinear optics, similar resonance structures were obtained for thiazine dyes. So, the spectroscopic technique can be considered as a simple method for prediction of dominant resonance structures and effective solvent polarity parameters on the third-order nonlinear properties of azure A and methylene blue dyes.

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.

Isolation of bacterial strains able to metabolize lignin and lignin-related compounds

In this study, we identified five strains isolated from soil and sediments able to degrade kraft lignin, aromatic dyes and lignin derivatives. Using 16S rRNA gene sequencing, the isolates were identified as Serratia sp. JHT01, Serratia liquefacien PT01, Pseudomonas chlororaphis PT02, Stenotrophomonas maltophilia PT03 and Mesorhizobium sp. PT04. All the isolates showed significant growth on lignin with no water-extractable compounds. Synthetic aromatic dyes were used to assess the presence of oxidative enzymes. All the isolates were able to use the thiazine dye Methylene blue and the anthraquinone dye Remazol Brilliant Blue R as the sole carbon source. Guaiacol, veratryl alcohol and biphenyl were also mineralized by all the strains isolated. These results suggest they could be used for the treatment of aromatic pollutants and for the degradation of the lignocellulosic biomass. Significance and Impact of the StudyThe valorization of waste lignin and lignocellulosic biomass by biocatalysis opens up new possibilities for the production of value-added substituted aromatics, biofuel and for the treatment of aromatic pollutants. Bacteria with ligninolytic potential could be a source of novel enzymes for controlled lignin depolymerization. In this work, five soil bacteria were isolated and studied. Every isolate showed significant growth on lignin and was able to degrade several lignin monomers and ligninolytic indicator dyes. They could thus be a source of novel ligninolytic enzymes as well as candidates for a bacterial consortium for the delignification of lignocellulosic biomass.

Photocatalysis with Pt-Au-ZnO and Au-ZnO Hybrids: Effect of Charge Accumulation and Discharge Properties of Metal Nanoparticles

Metal-semiconductor hybrid nanomaterials are becoming increasingly popular for photocatalytic degradation of organic pollutants. Herein, a seed-assisted photodeposition approach is put forward for the site-specific growth of Pt on Au-ZnO particles (Pt- Au-ZnO). A similar approach was also utilized to enlarge the Au nanoparticles at epitaxial Au-ZnO particles (Au@Au-ZnO). An epitaxial connection at the Au-ZnO interface was found to be critical for the site-specific deposition of Pt or Au. Light on-off photocatalysis tests, utilizing a thiazine dye (toluidine blue) as a model organic compound, were conducted and confirmed the superior photodegradation properties of Pt-Au-ZnO hybrids compared to Au-ZnO. In contrast, Au-ZnO type hybrids were more effective toward photoreduction of toluidine blue to leucotoluidine blue. It was deemed that photoexcited electrons of Au- ZnO (Au, similar to 5 nm) possessed high reducing power owing to electron accumulation and negative shift in Fermi level/redox potential; however, exciton recombination due to possible Fermi-level equilibration slowed down the complete degradation of toluidine blue. In the case of Au@Au-ZnO (Au, similar to 15 nm), the photodegradation efficiency was enhanced and the photoreduction rate reduced compared to Au-ZnO. Pt-Au-ZnO hybrids showed better photodegradation and mineralization properties compared to both Au-ZnO and Au@Au-ZnO owing to a fast electron discharge (i.e. better electron-hole seperation). However, photoexcited electrons lacked the reducing power for the photoreduction of toluidine blue. The ultimate photodegradation efficiencies of Pt-Au-ZnO, Au@Au-ZnO, and Au-ZnO were 84, 66, and 39%, respectively. In the interest of effective metal-semiconductor type photocatalysts, the present study points out the importance of choosing the right metal, depending on whether a photoreduction and/or photodegradation process is desired.
