Copper(I)-Catalyzed Oxidative Coupling between 2-Aminobenzothiazole and Terminal Alkyne: Formation of Benzothiazine

An unprecedented formation of benzothiazine during copper(I)-catalyzed oxidative coupling of 2-aminobenzothiazole and terminal alkyne in air has been observed. This unique transformation possibly occurs through the ring opening of 2-aminobenzothiazole and subsequent oxidative coupling with alkyne followed by intramolecular cyclization. A variety of substituted benzo[b][1,4]thiazine-4-carbonitriles are obtained by this protocol.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 154445-78-0, you can contact me at any time and look forward to more communication. Name: 2,2,4,6,7-Pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl chloride.

Synthesis of New Azoles and Azolopyrimidines Incorporating Morpholine Moiety as Potent Anti-Tumor Agents

A new series of morpholinyl-chalcones 2a-d was prepared by reaction of 2-oxo-N,4-diarylbut-3-enehydrazonoyl chlorides 1a-d with morpholine. These chalcones were used as a building block for constructing pyrazoles 3a-d and 3,4-dihydropyrimidine-2(1H)-thione 6 via their reaction with phenylhydrazine and thiourea, respectively. Moreover, a new series of azolopyrimidine derivatives 11a,b, 15, 17, 19, and 21 incorporating morpholine moiety were synthesized by reaction of 1-morpholino-4-phenyl 1 (2 phenylhydrazono)but-3-en-2-one (2a) with a number of heterocyclic amines in the presence of a catalytic amount of acetic acid. The assigned structures for all the newly synthesized compounds were confirmed on the basis of elemental analyses and spectral data and the mechanisms of their formation were also discussed. All the synthesized compounds were tested for in vitro activities against two antitumor cell lines, human lung cancer (A-549) and human hepatocellular carcinoma (HepG-2) compared with the employed standard antitumor drug (cisplatin) and the results revealed that compounds 6, 8c and 17 have promising activities compared with cisplatin.

Comparative transcriptome analysis of Anguilla japonica livers following exposure to methylene blue

The thiazine dye methylene blue is widely used as a disinfectant and antidote in veterinary medicine. Here, we compared transcriptome differences in the liver of Anguilla japonica exposed to methylene blue using Illumina RNA sequencing technology. A total of 75,953,174 and 86,499,866 clean reads with an average length of 126bp from control and treatment groups respectively. A total of 148,238 transcripts were assembled, with 62,152 components were assembled. Overall, 416,991 unigenes were checked against the National Center of Biotechnology Information, Non-redundant, Cluster of Orthologous Groups (COG), and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases. Of these, 18,541 genes were judged to be differently expressed. The gene ontology (GO) terms molecular function and biological process were the most enriched in protein binding, followed by ATP binding and regulation of transcription, and DNA-dependent. KEGG pathway analysis revealed significant enrichment of N-glycan biosynthesis and the citrate cycle. This study determined that unigenes related to transmembrane transport and drug metabolism in A.japonica were differentially expressed following exposure to methylene blue. These findings can shed insight into the mechanism of methylene blue metabolism in this economically important species.

Reinvestigations into synthesis of allyldithiocarbamates and their intramolecular cyclization: synthesis and antihyperglycemic activity of 2-thioxothiazolidine-4-alkanoates

Reinvestigating the synthesis of allylthiocarbamates from MBH derivatives revealed that they are obtained more efficiently from allylbromides in isopropanol rather than acetates in water. Further unlike reported, the base-mediated intramolecular cyclization of these allyldithiocarbamates give substituted 2-thioxothiazolidine-4-alkanoates instead of substituted 1,3-thiazines and the reaction was restricted to 2- or 4-nitrophenyl carrying substrates. Screening of these products for antihyperglycemic activity revealed that 5bC displays significant activity via partial agonist activity on PPAR gamma at transcriptional level, which was corroborated by molecular docking studies.

Ecofriendly pH-Tunable Hydrogels for Removal of Perilous Thiazine Dye

Reactive dyes are extremely toxic and harmful to the environment even present at very low concentration. In this study, sodium alginate based reusable hydrogels was prepared for the removal of methylene blue from waste water. pH-tunable hydrogels was prepared by the introduction of ionic pendant functionalities on sodium alginate (SA) by the utilization of ethylene glycol and acrylic acid through condensation followed by free radical polymerization. The structure, formation and thermal stability of hydrogel was identified by Fourier transform infra red spectroscopy and thermogravimetric analysis respectively. Swelling nature at different pH ranges and the humidity contents of both dried and dye adsorbed hydrogels was investigated. The morphology of the dry and dye adsorbed hydrogel was also studied using scanning electron microscopy. The swelling studies infer that pronounced swelling obtained at higher pH than at lower pH. The surface morphology of plain hydrogel before and after adsorption of methylene blue (MB) was examined by SEA analysis. The adsorption tendency of the SEA hydrogel in MB was steadily investigated at different pH, contact time, concentration dye and adsorbent dosage. All prepared hydrogels were performed well in the removal of MB from waste water up to 80-98%. Recycling of hydrogels has a vital role for waste water treatment and it can be done by desorption studies which shows that 0.1 N HCl revealed higher elution efficiency i.e. 90.00%. Furthermore, adsorption-desorption studies suggested that SA based hydrogels contributes to enhance the removal efficacy, which renders the hydrogels well-designed for the efficient removal of cationic dyes (MB). However, polyol based hydrogels have been chosen for an adsorbent because of low-cost, ecofriendly, biocompatible and efficient biosorbents. [GRAPHICS] .

Crystal structure of rac-2,3-diphenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one 1-oxide

In the title compound, C(16)Hi(5)NO(2)S [alternative name: rac-2,3-diphenyl-1,3-thiazinan-4-one 1-oxide], the thiazine ring exhibits an envelope conformation, with the S atom forming the flap. The sulfoxide 0 atom is in a pseudo-axial position on the thiazine ring and is trans to the phenyl group on C-2. The phenyl rings form a dihedral angle of 89.47 (19)degrees. In this racemate crystal, homochiral molecules form slabs parallel to (010) of thickness b/2 which then stack with alternating chirality in the b-axis direction. The stacking is aided by edge-to-face interactions between the phenyl rings of racemic molecules. Within each of the single-enantiomer slabs, the molecules are held by C-H center dot center dot center dot O-type interactions, with an H center dot center dot center dot O distance of 2.30 angstrom, forming infinite chains along the c-axis direction, as well by the edge-to-face interactions between phenyl rings of neighboring molecules in the a-axis direction.

Synthesis of Antifungal Agents from Xanthene and Thiazine Dyes and Analysis of Their Effects

Indoor fungi growth is an increasing home health problem as our homes are more tightly sealed. One thing that limits durability of the antifungal agents is the scarcity of reactive sites on many surfaces to attach these agents. In order to increase graft yield of photosensitizers to the fabrics, poly(acrylic acid-co-styrene sulfonic acid-co-vinyl benzyl rose bengal or phloxine B) were polymerized and then grafted to electrospun fabrics. In an alternative process, azure A or toluidine blue O were grafted to poly(acrylic acid), which was subsequently grafted to nanofiber-based and microfiber-based fabrics. The fabrics grafted with photosensitizers induced antifungal effects on all seven types of fungi in the order of rose bengal > phloxine B > toluidine blue O > azure A, which follows the quantum yield production of singlet oxygen for these photoactive dyes. Their inhibition rates for inactivating fungal spores decreased in the order of P. cinnamomi, T. viride, A. niger, A. fumigatus, C. globosum, P. funiculosum, and M. grisea, which is associated with lipid composition in membrane and the morphology of fungal spores. The antifungal activity was also correlated with the surface area of fabric types which grafted the photosensitizer covalently on the surface as determined by the bound color strength.

Cyclization of N-benzyl cyanoacetamide: Novel synthesis and biological activity of pyrrole, pyrimidine, and pyran derivatives

Heteroannulation of N-Benzyl cyanoacetamide 1 to a new series of heterocycles has been developed. Thus, reaction of 1 with different polarized pi systems afforded pyrrolo 4, pyridone 6, pyridine 8, and diazapene 10 derivatives, respectively. N-Benzyl cyanoacetamide that undergo condensation reaction with salicylaldehyde yielded pyran derivative 11. Nitrosation of 11 furnished condensed pyran 13. Compound 11 reacted with benzaldehyde, carbon disulfide (cyclizing agent), and ammonium thiocyanate to provide pyrane 17, thiazine 18, and thiourea 20 derivatives, respectively. Cinnamoyl isothiocyanate was reacted with compound 11 to produce non-isolable thiourea derivative 21. The newly synthesized compounds have been characterized by infrared (IR), proton nuclear magnetic resonance (H-1 NMR), and carbon nuclear magnetic resonance (C-13 NMR) spectral data. The compounds were then evaluated for antibacterial and anticancer activities.

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

Potent Ex Vivo Activity of Naphthoquine and Methylene Blue against Drug-Resistant Clinical Isolates of Plasmodium falciparum and Plasmodium vivax

The 4-aminoquinoline naphthoquine (NQ) and the thiazine dye methylene blue (MB) have potent in vitro efficacies against Plasmodium falciparum, but susceptibility data for P. vivax are limited. The species- and stage-specific ex vivo activities of NQ and MB were assessed using a modified schizont maturation assay on clinical field isolates from Papua, Indonesia, where multidrug-resistant P. falciparum and P. vivax are prevalent. Both compounds were highly active against P. falciparum (median [range] 50% inhibitory concentration [IC50]: NQ, 8.0 nM [2.6 to 71.8 nM]; and MB, 1.6 nM [0.2 to 7.0 nM]) and P. vivax (NQ, 7.8 nM [1.5 to 34.2 nM]; and MB, 1.2 nM [0.4 to 4.3 nM]). Stage-specific drug susceptibility assays revealed significantly greater IC(50)s in parasites exposed at the trophozoite stage than at the ring stage for NQ in P. falciparum (26.5 versus 5.1 nM, P = 0.021) and P. vivax (341.6 versus 6.5 nM, P = 0.021) and for MB in P. vivax (10.1 versus 1.6 nM, P = 0.010). The excellent ex vivo activities of NQ and MB against both P. falciparum and P. vivax highlight their potential utility for the treatment of multidrug-resistant malaria in areas where both species are endemic.
