N-alkylphenothiazines – synthesis, structure and application as ligands in metal complexes

Phenothiazines are a large group of heterocyclic, aromatic molecules with nitrogen and sulphur between two benzene rings. Their derivatives, N-alkylphenothiazines have substituent on heterocyclic nitrogen atom which gives them different properties. Also, a series of these molecules have substitution on carbon atom at place 2 of phenothiazine benzene ring. Alkylphenothiazines contain aminoalkyl substituent and their alkyl, acyl and sulphonil derivatives, as well as monocyclic and bicyclic heterocycles attached at thiazine nitrogen atom or directly linked to benzene ring. The N-alkylphenothiazines have been known as antipsychotic drugs, but they also possess antibacterial, antifungal, anticancer activity, and ability to react with macromolecules and to coordinate to the metals. Metal complexes with N-alkylphenothiazines are biological active compounds with different antimicrobial activities and cytotoxic effect against tumor cell lines. The large field of application of N-alkylphenothiazines is very attractive in terms of synthesis of new related derivatives, metal complexes, studying their properties and applications. This article presents a review of the literature and a contemporary view at N-alkylphenothiazines – their synthesis and application, as well as their metal complexes which have promising biological effects.

Annulation reaction of methyl 2-(benzo[b][1,4]thiazin-3-ylidene) acetate with beta-nitrostyrenes and 3-nitrochromenes

The acid catalyzed domino reaction of beta-nitrostyrenes with methyl 2-(benzo[b][1,4]thiazin-3-ylidene) acetate, which were previously prepared from the cyclization of 2-aminobenzenethiol and methyl 4-chloroacetoacetate, resulted in 2-arylbenzo[b]pyrrolo[1,2-d][1,4]thiazine-3-carboxylates in high yields. Under same reaction conditions, the similar reaction with 3-nitrochromenes afforded corresponding benzo[b]chromeno[4′,3′:4,5]pyrrolo[1,2-d][1,4]thiazine derivatives in good yields.

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.

Methylene blue induces an analgesic effect by significantly decreasing neural firing rates and improves pain behaviors in rats

Methylene blue (MB) is a blue cationic thiazine dye and currently used in different medical settings. Notably, there have been several attempts to introduce MB for attenuating pain in the last decade. Some clinical studies reported remarkable results, which, however, have been much debated. In addition, accumulating evidence have revealed that MB diminishes voltage-gated sodium channel currents. Accordingly, in the present study, we conducted in vivo experiments, including in vivo single nerve recording and behavioral test, to investigate whether MB dampens neural firing rates and ultimately contributes to pain relief. As a result, neural firing rates significantly decreased and finally converged to zero after MB administration. This event lasted longer than that of lidocaine and was dose-dependently modulated. Furthermore, there was a marked improvement in pain behaviors. The withdrawal threshold and latency of hind paws significantly rose post-MB administration. Therefore, these results demonstrate that MB lessens pain by significantly weakening neural excitability, which implies a strong possibility that this dye may be developed as a pain-relieving medication in the future. This is the first in vivo study to elucidate the effect of MB on nerves and pain relief. (C) 2021 Elsevier Inc. All rights reserved.

One-Pot Multicomponent Synthesis and Anticancer Activity of 1,3-Cyclopentathiazine and Pyrimidothiazine Derivatives

Novel 1,3-cyclopentathiazine and pyrimidothiazine derivatives were synthesized starting from 7-benzyl-4-phenylcyclopenta[d][1,3]thiazin-2-amine (CTA) prepared by a one-pot multicomponent reaction of cyclopentanone, benzaldehyde, and thiourea. Cyclocondensation of CTA with benzylidenemalononitrile gave a pyrimidothiazine. Oxidation of cyclopentathiazine with hydrogen peroxide afforded the corresponding epoxide, while its alkylation with ethyl iodide yielded anN-ethyl derivative. Cyclopentylidenemalononitrile was reacted with formaline and carbon disulfide to obtain pyridine-4-carbonitrile and thiapyrane, respectively, and the reactions of cyclopentylidenemalononitrile with aryl isocyanate and aryl isothiocyanate gave condensed diimino-substituted cyclopentanaphthyridine-1,6-dione and dithiaacenaphthylene-3,8-diylidedibenzamide, respectively. Heating cyclopentanone with benzoyl isothiocyanate and benzoyl chloride produced a sulfide derivative and an enolic dione, respectively. The structures of the newly synthesized compounds were confirmed by spectral analysis, and some products were screened for anticancer activity.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 103-47-9 is helpful to your research. SDS of cas: 103-47-9.

Exploring the antimalarial potential of the methoxy-thiazinoquinone scaffold: Identification of a new lead candidate

A small library of antiplasmodial methoxy-thiazinoquinones, rationally designed on the model of the previously identified hit 1, has been prepared by a simple and inexpensive procedure. The synthetic derivatives have been subjected to in vitro pharmacological screening, including antiplasmodial and toxicity assays. These studies afforded a new lead candidate, compound 9, endowed with higher antiplasmodial potency compared to 1, a good selectivity index when tested against a panel of mammalian cells, no toxicity against RBCs, a synergistic antiplasmodial action in combination with dihydroartemisinin, and a promising inhibitory activity on stage V gametocyte growth. Computational studies provided useful insights into the structural requirements needed for the antiplasmodial activity of thiazinoquinone compounds and on their putative mechanism of action.
