Antimicrobial Properties of Substituted Quino [3,2-b]benzo[1,4] thiazines

Our previous studies demonstrated that among phenothiazines several derivatives could be found showing strong antiproliferative actions and the property of inhibiting inducible tumor necrosis factor alpha (TNF alpha) production in human blood cultures. The aim of this investigation was to determine potential antimicrobial actions of forty four new phenothiazine derivatives with the quinobenzothiazine structure. The compounds showed differential antibacterial and antifungal activities against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans depending on the compound structures, concentrations and bacterial strains. More specifically, 6-(1-methyl-2-piperidylethyl) quinobenzothiazine displayed strongest actions against S. aureus and E. coli whereas 6-methanesulfonylaminobutyl-9-methylthioquinobenzothiazine exhibited the most universal antimicrobial properties. The correlation between antimicrobial activity and the chemical structure of quinobenzothiazines was discussed.

Synthesis, reactions, and antimicrobial evaluations of new benzo[e][1,3]thiazine derivatives

4H-Spiro[benzo[d][1,3]oxathiine-2,1 ‘-cyclohexan]-4-one undergoes aminolysis with certain aromatic amines to give the respective 4-benzenesulfonamide, Ethyl benzoate, and 4-acetylphenyl of 4-oxospirobenzo[e][1,3]thiazine derivatives. The Schiff bases prepared by reacting Ethyl benzoate derivative 2a with aldehydes, undergoes cyclocondensation with thioglycolic acid yielding p-methoxyphenyl and 2-(thiophen-2-yl) thiazolidinone derivatives. Treatment of the benzoate derivative with hydrazine hydrate afforded the corresponding benzohydrazide derivative which upon reaction with phenyl isocyanate and phenyl isothiocyanate afforded the urea and thiourea derivatives. New pyrimidine, pyridone, and imino pyridine derivatives of 4-oxospirobenzo[e][1,3]thiazine were also successfully prepared by reacting 2b or 2c with the appropriate organic reagents. Structural elucidations for the new products were based upon compatible microanalytical and spectroscopic measurements.

Targeting SARS-CoV-2: Novel Source of Antiviral Compound(s) against COVID-19?

SARS-CoV-2 remains a significant burden on human health. Several lines of evidence suggest that surveillance of sewage and waste can provide an early warning sign for COVID-19 recurrence in a community. In support, SARS-CoV-2 traces were found in sewage in several countries. With this in mind, it is notable that pests, such as cockroaches, are exposed to pathogenic microbes routinely, yet thrive in polluted environments. Such species have likely developed mechanisms to protect themselves against pathogens. In support, recent studies showed that cockroaches possess potent antibacterial molecules to shield themselves from pathogenic bacteria. Among hundreds of molecules, some contained thiazine groups, imidazoles, chromene derivatives, isoquinoline group, sulfonamides, pyrrole-containing analogs, flavanones, and furanones. Here, we propose that cockroaches are a potential source of antiviral molecules to thwart infections. Because this is an unexploited resource for potential antivirals, we believe that cockroaches offer a unique source for novel bioactive molecule(s) to counter COVID-19 with huge clinical impact worldwide.

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.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 92-39-7. The above is the message from the blog manager. Recommanded Product: 92-39-7.

Synthesis of 2,6-dicarbethoxy-3,5-diaryltetrahydro-1,4-thiazine-1, 1-dioxide derivatives as potent anticonvulsant agents

An efficient synthesis of 2,6-dicarbethoxy-3,5-diaryltetrahydro-1,4-thiazine-1,1-dioxide derivatives has been achieved under aqueous medium for the first time in good to excellent yields. All the synthesized compounds were tested for anticonvulsant activity using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) screens, which are the most broadly employed seizure models for early identification of candidate anticonvulsants. Their neurotoxicity was determined applying the rotarod test. Seven compounds 4a, 4d, 4f, 4h, 4o, 4p and 4q showed promising anticonvulsant activities in both models employed for anticonvulsant evaluation. The most active compound 4d showed the MES-induced seizures with ED50 value of 10.2 mg/kg and TD50 value of 288.6 mg/kg after intraperitoneal injection to mice, which provided compound 4d with a protective index (TD50/ED50) of 28.3 in the MES test.

Enhancement of nonlinear optical response of methylene blue and azure a during association with colloidal CdS quantum dots

The nonlinear optical response of thiazine dyes during association with colloidal CdS quantum dots (QDs) applying the z-scan technique at wavelength of 532 nm with use 10 ns pulses of Nd:YAG laser second harmonic were studied. Increasing in nonlinear absorption intensity in hybrid associates in comparison with the initial components were found. Moreover, UV-vis absorption spectrum shows the effective formation of dyes H-aggregates during association with colloidal QDs. Two-photon mechanism of observed nonlinear absorption in hybrid associates is proposed, based on a sharper dependence of the normalized transmittance on the incident intensity (distance between the sample and focal plane of focusing lens). And for pure solutions, the reverse saturated absorption is preferred nonlinear absorption mechanism. The nonlinear absorption coefficients for MB and AzA in the hybrid associates were found. They are beta approximate to 8.4 x 10(-9) cm W-1 (sic) approximate to 1.34 x 10(-8) cm W-1, respectively. It was shown that it is possible to control the parameters of nonlinear absorption of thiazine dyes via the hybrid association.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

N-Radical Initiated Aminosulfonylation of Unactivated C(sp(3))-H Bond through Insertion of Sulfur Dioxide

N-Radical initiated aminosulfonylation of unactivated C(sp(3))-H bond through insertion of sulfur dioxide in the presence of visible light is reported. O-Aryl oximes react with DABCO center dot(SO2)(2) smoothly at room temperature under blue LED irradiation without any metals or photoredox catalysts, generating diverse 5,6-dihydro-4H-1,2-thiazine 1,1-dioxides in good yield. Additionally, this approach can be extended to the synthesis of 1H-benzo[d][1,2]thiazine 2,2-dioxides. During the reaction process, an N-radical is initiated by the treatment of O-aryl oximes with DABC center dot(SO2)(2) under visible-light irradiation. It is followed by aminosulfonylation of a nearby C(sp(3)) H bond through 1,5-hydrogen atom transfer with accompanying insertion of sulfur dioxide to provide 1,2-thiazine 1,1-dioxide derivatives.
