NOVEL SYNTHESIS, RING TRANSFORMATION AND ANTICANCER ACTIVITY OF 1,3-THIAZINE, PYRIMIDINE AND TRIAZOLO[1,5-a]PYRIMIDINE DERIVATIVES

Synthesis, heterocyclization and anticancer activity of a new series of heterocyclic compounds are described. Aminothiazine 1 was obtained from the base induced condensation of thiourea, benzaldehyde and ethyl cyanoacetate. The synthesis of N-phenyl amino pyrimidine derivative 2 was obtained as a result of reaction of aniline with compound 1. Compound 2 underwent ring opening and recyclization upon reaction with HCl or H2O2/NaOH to afford the acid derivative 3 or oxazine 4, respectively. Thiazine 1 undergoes ring transformation upon the effect of NH2OH center dot HCl to produce pyrimidine derivative 5. Heterocyclization of compound 1 with thiosemicarbazide followed by oxidation with I-2/AcOH afforded triazolopyrimidine 6 and 7, respectively. Alkylation of compound 1 was promoted by reaction of 1 with ethyl iodide to give alkylated thiazine 8 which in turn undergo ring transformation when subjected to reaction with hydrazine hydrate to give pyrazole derivative 9. Refluxing of amino-1,3-thiazine derivative 1 with ethyl bromoacetate in the presence of Et3N produce the alkylated pyrimidine product 10. Hydrazonolysis of 1,3-thiazine 1 with hydrazine or phenyhydrazine gave pyrimidine derivatives 11a,b, respectively. Compound 11b was cyclized with carbon disulfide or formaldehyde to produce triazolopyrimidines 12 and 13, respectively. Some of the new compounds were screened for anticancer activity and significant results were found for some compounds.

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.

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.

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.

Revealing electronic features governing hydrolysis of cephalosporins in the active site of the L1 metallo-beta-lactamase

The QM/MM simulations followed by electron density feature analysis are carried out to deepen the understanding of the reaction mechanism of cephalosporin hydrolysis in the active site of the L1 metallo-beta-lactamase. The differences in reactivity of ten similar cephalosporin compounds are explained by using an extended set of bonding descriptors. The limiting step of the reaction is characterized by the proton transfer to the nitrogen atom of the cephalosporin thiazine ring accompanied with formation of the C-4 & xe001;C-3 double bond in its N-C-4-C-3 fragment. The temporary NMIDLINE HORIZONTAL ELLIPSISH-O-w hydrogen bond, which is formed in the transition state of the limiting step of the reaction was recognized as a key atomic interaction governing the reactivity of various cephalosporins. Non-local real-space bonding descriptors show that different extent of localization of electron lone pair at N atom in the transition state affect the reactivity of compounds: smaller electron localization is typical for the less reactive species. In particular, the Fermi hole analysis shows how exchange electron correlation in the NMIDLINE HORIZONTAL ELLIPSISH-O-w fragment control electron lone pair localization. Delocalization tensor, linear response kernel and source function indicate that features of electron delocalization in the N-C-4-C-3 fragment of cephalosporins in the transition state complexes determine the differences in C-4-C-3 bond for substrates with high and low rate constants. The C-4-C-3 bond of the N-C-4-C-3 fragment at the transition state is similar to that of the preceding intermediate for the less reactive species and resembles the features of the enzyme-product complex for more reactive compounds. The power and limitations of the descriptors applied for solving the problem are discussed and the generality of approach is stressed.
