Intramolecular C-O/C-S bond insertion of alpha-diazoesters for the synthesis of 2-aryl-4H-benzo[d][1,3]oxazine and 2-aryl-4H-benzo[d][1,3]thiazine derivatives

An intramolecular C-O insertion of 2-(2-arylamidophenyl)-2-diazoacetate has been achieved using a catalytic amount of copper triflate under mild conditions to produce 2-aryl-4H-benzo[d][1,3]oxazine-4-carboxylate in good yields. In addition, 2-diazo-2-(2-arylthioamidophenyl)acetate affords the corresponding 2-aryl-4H-benzo[d][1,3]thiazine derivatives under similar conditions. This is the first example of the synthesis of benzoxazines and benzothiazines from ortho-amidophenyl diazoacetate and ortho-thioamidophenyl diazoacetate, respectively.

Characterization of biogenically synthesized silver nanoparticles for therapeutic applications and enzyme nanocomplex generation

The present study describes green synthesis of silver nanoparticles (AgNPs) and inulin hydrolyzing enzyme nanocomplexes (ENC) usingAzadirachta indica(Ai) andPunica granatum(Pg) leaf extracts. Surface topology and physico-chemical characteristics of AgNPs were studied using surface plasmon resonance (SPR), FTIR, SEM, AFM and EDX analyses. Particle size analysis using dynamic light scattering and AFM studies revealed thatAi-AgNPs (76.4 nm) were spherical in shape having central bigger nano-regime with smaller surroundings whilePg-AgNPs (72.1 nm) and ENCs (Inulinase-Pg-AgNPs similar to 145 nm) were spherical particles having smooth surfaces.Pg-AgNPs exhibited significant photocatalysis of a thiazine dye, methylene blue. BothAi-andPg-AgNPs showed selective antibacterial action by inhibiting pathogenicBacillus cereus, while the probioticLactobacillusstrains remained unaffected.Ai-AgNPs showed potential anti-biofilm effect (30% viability) onB. cereusbiofilms.Pg-AgNPs showed anti-cancer effect against human colon cancer cell lines (Caco-2) resulting in 40% cell death in 48 h. Enzymes (inulinase, L-asparaginase and glucose oxidase) were successfully immobilized onto nanoparticles together with the biogenic synthesis of AgNPs and recyclability of the Inulinase-Pg-AgNPs complex was demonstrated. The study elaborates characteristics of green synthesized nanoparticles and their potential applications as anti-cancer, antibacterial and antioxidant nano drugs that could be used in food and nutraceutical industries. Enzyme immobilization on AgNPs without any toxic cross-linker opens up newer possibilites in enzyme-nanocomplex research.

Cresyl Violet Stains Mast Cells Selectively: Its Application to Counterstaining in Immunohistochemistry

The thiazine dye toluidine blue (TB) is well known to stain mast cells and hyaline cartilage metachromatically, and thus is mostly often used for their identification. However, TB is not suitable for counterstaining in immunohistochemistry, because of its high-background staining in the cytoplasm of other cell species and in extracellular structures. To expand the knowledge about dyestuffs staining mast cells in consideration with their usage in immunohistochemistry, we determined the stainability of several thiazines and oxazines, which are structurally related compounds to TB, using sections of mast cell-containing tissues. We found that all azine dyes used metachromatically stained mast cells and cartilage. Among these dyes, an oxazines cresyl violet (CV) stained mast cells with lower background, suggesting that those are useful for detecting mast cells and for counterstaining in immunohistochemistry. To ascertain its utility, CV was used in immunostaining of bHSDs in sections from adult rat ovary. Immunopositive signals reflected by DAB development in brown were clearly detected even after CV staining. We conclude that, similar to thiazines, oxazines stain mast cells metachromatically, and that of these, CV is more useful as a counterstain in immunohistochemistry than TB.

Spectral and kinetic features of nonradiative energy transfer in hybrid associates of colloidal quantum dots and organic dyes

The features of nonradiative resonance energy transfer in hybrid associates of colloidal CdS quantum dots (QDs) with molecules of a thiazine dye and J-aggregates of a carbocyanine dye are discussed. The case of an inhomogeneously broadened recombination band of donor (CdS QDs) luminescence is considered. We detected spectral-selective quenching of recombination luminescence of colloidal CdS QDs in association with organic dyes. The maximum of quenching occurs in the region of absorption of the acceptor (organic dye molecule). It is shown using the time-correlated single photon counting technique that the lifetime of the QD luminescence decreases synchronously with the quenching of the luminescence, but only at the wavelengths falling in the region of absorption of the dye. Based on the concept of a donor-acceptor nature of emission of CdS QDs, the dependence of the efficiency of nonradiative energy transfer on the luminescence wavelength is analyzed taking into account the Poisson distribution of its quenchers.

All the synthesized compounds were tested for in vitro activities against two antitumor cell lines, human lung cancer and human hepatocellular carcinoma compared with the employed standard antitumor drug (cisplatin). Conclusions: All the newly synthesized compounds were evaluated for their anticancer activity against human lung cancer and human hepatocellular carcinoma cell lines using MTT assay. The results obtained exploring the high potency of six of the tested compounds compared with cisplatin.

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.
