A turn on ESIPT probe for rapid and ratiometric fluorogenic detection of homocysteine and cysteine in water with live cell-imaging

5(Benzothiazol-2-yl)-4-hydroxyisophthalaldehyde (BHI), an intense ESIPT containing molecule in mixed media loses its properties due to resonance-assisted H-bond (RAHB) in absolute water. Due to resonance-assisted H-bond the o-aldehyde is more reactive than the other one. With addition of cysteine/homocysteine into this solution the o-aldehyde group gets transformed into thiazolidine/thiazine ring, respectively, and the phenolic proton becomes free enough for transfer to nitrogen of the benzothiazole ring in excited state, that is, the ESIPT of BHI is turned on. Thus we can detect cysteine/homocysteine in water as well as in live cells. (C) 2013 Elsevier Ltd. All rights reserved.

Novel temperature-activated humidity-sensitive optical sensor

A novel, colorimetric, temperature-activated humidity indicator is presented, with a colour change based on the semi-reversible aggregation of thiazine dyes (esp. methylene blue, MB) encapsulated within the polymer, hydroxypropyl cellulose (HPC). The initially purple MB/HPC film is activated by heat treatment at 370 degrees C for 4 s, at which point the film (with a colour associated with that of a highly aggregated form of MB; lambda(max) = 530 nm) becomes blue (indicating the presence of monomeric and dimeric MB; i.e. with lambda(max) = 665; 605 nm respectively). The blue, heat-treated MB/HPC films respond to an ambient environment with a relative humidity (RH) exceeding 70% at 21 degrees C within seconds, returning to their initial purple colour. This colour change is irreversible until the film is heat-treated once more. When exposed to a lower RH of up to ca. 47%, the film is stable in its blue form. In contrast, a MB/HPC film treated only at 220 degrees C for 15 s also turns a blue colour and responds in the same way to a RH value of ca. 70%, but it is unstable at moderate RH 37-50% values, so that it gradually returns to its purple form over a period of approximately 6 h. The possible use of the high heat-treated MB/HPC humidity indicator in the packaging of goods that cannot tolerate high RH, such as dry foods and electronics, is discussed. (C) 2016 Elsevier B.V.

L-Arginine/Nitric Oxide Pathway Is Altered in Colorectal Cancer and Can Be Modulated by Novel Derivatives from Oxicam Class of Non-Steroidal Anti-Inflammatory Drugs

Simple Summary Nitric oxide and arginine metabolism in colorectal cancer (CRC) holds potential for therapeutic intervention. We hypothesized that it can be modulated by oxicams, a class of non-steroidal anti-inflammatory drugs with documented chemopreventive and antineoplastic activity. The aim of this study was to determine the transcriptional patterns of pathway enzymes in CRC and evaluate the impact of classic and new oxicam analogues. Arginine metabolic pathways were altered not only in tumors but also in non-transformed mucosa from tumor vicinity, contributing to the phenomenon of tumor molecular margin. Classic oxicams, piroxicam and meloxicam, had negligible impact but their new analogues downregulated expression of dimethylarginine dimethylaminohydrolases and protein methyltransferases and upregulated asymmetric dimethylarginine. Those beneficial effects were accompanied by upregulation of arginase-2 and the potentially disadvantageous accumulation of arginine and symmetric dimethylarginine. Our findings provide novel insight into metabolic reprogramming in CRC and demonstrate that oxicam analogues are worth further consideration as novel anticancer agents. L-arginine/nitric oxide pathway metabolites are altered in colorectal cancer (CRC). We evaluated underlying changes in pathway enzymes in 55 paired tumor/tumor-adjacent samples and 20 normal mucosa using quantitative-PCR and assessed the impact of classic and novel oxicam analogues on enzyme expression and intracellular metabolite concentration (LC-MS/MS) in Caco-2, HCT116, and HT-29 cells. Compared to normal mucosa, ARG1, PRMT1, and PRMT5 were overexpressed in both tumor and tumor-adjacent tissue and DDAH2 solely in tumor-adjacent tissue. Tumor-adjacent tissue had higher expression of ARG1, DDAH1, and DDAH2 and lower NOS2 than patients-matched tumors. The ARG1 expression in tumors increased along with tumor grade and reflected lymph node involvement. Novel oxicam analogues with arylpiperazine moiety at the thiazine ring were more effective in downregulating DDAHs and PRMTs and upregulating ARG2 than piroxicam and meloxicam. An analogue distinguished by propylene linker between thiazine’s and piperazine’s nitrogen atoms and containing two fluorine substituents was the strongest inhibitor of DDAHs and PRMTs expression, while an analogue containing propylene linker but no fluorine substituents was the strongest inhibitor of ARG2 expression. Metabolic reprogramming in CRC includes overexpression of DDAHs and PRMTs in addition to ARG1 and NOS2 and is not restricted to tumor tissue but can be modulated by novel oxicam analogues.

Crystal structure of cyclic sulfin- and sulfonamides of the thiazine series: Conformation, intra- and intermolecular interactions

An X-ray crystallographic study of a new compound is performed and the structure of five sulfin- and sulfonamides of the thiazine series is discussed. The conformation of the thiazine ring in all structures (a distorted boat) is stabilized by the intramolecular interaction of the C-HaEuro broken vertical bar N type. The nitrogen atom of the thiazine ring has a pyramidal configuration. The geometry of isolated molecules is calculated at density functional theory level (PBE1PBE, 6-31G(d,p)) and compared to that observed in the crystals. In the crystal structures different packing motifs are implemented with the formation of supramolecular associates of different types due to classical hydrogen bonds such as N-H center dot center dot center dot O.

Based on spectral data and magnetic moments, an octahedral geometry may be proposed for the synthesized complexes except cerium(III) complex which has pentagonal bipyramidal arrangement. The low values of the molar conductance indicate non-electrolyte nature of complexes, while 1:1 electrolyte for cerium(III)- and chromium(III)-complexes. The Coats-Redfern equation was used to calculate the kinetic and thermodynamic parameters for the different thermal decomposition steps of some complexes. All the synthesized compounds were tested for in vitro antibacterial activity against some Gram-positive and Gram-negative bacteria, yeast and fungus. Molecular structure of the Schiff base ligand and its complexes were optimized for the proposed structures on the basis of semiempirical PM3 method. (C) 2015 Elsevier B.V. All rights reserved.

The double Smiles rearrangement in neutral conditions leading to one of 10-(nitropyridinyl)dipyridothiazine isomers

Phenothiazines are reported to exhibit very promising anticancer, antibacterial, antifungal, anti-inflammatory activities, reversal of multidrug resistance and many other actions. Synthesis of phenotiazines is mostly carried cyclization of o-aminodiphenyl sulfides proceeded through the Smiles rearrangement. The modifications of the phenothiazine structure via the substitution of the benzene ring with the pyridine ring gave various pyridobenzothiazines and dipyridothiazines. The reaction of 3-amino-3′-nitro-2,2′-dipyridinyl sulfide with 4-chloro-3-nitropyridine in sole DMF led to one of four possible isomeric nitropyridinyldipyridothiazines. Two-dimensional H-1 and C-13 NMR experiments (COSY, ROESY, HSQC and HMBC) were used to reveal the right product structure as 10-(3′-nitro-4′-pyridinyl) dipyrido[2,3-b; 2′,3′-e] [1,4]thiazine (10-(3′-nitro-4′-pyridinyl)-1,6-diazaphenothiazine). The final structure confirmation came from a single crystal X-ray analysis. This structure is the result of very rare reaction mechanism involving the double Smiles rearrangement of the S-N type. The tricyclic dipyridothiazine system is unexpectedly almost planar, with the butterfly angle of 176.39(4) between two pyridine rings and 174.17(6)degrees between the halves of the thiazine ring (the NCCS) planes. The pyridinyl substituent is rotated about N10-C11 bond and oriented almost perpendicularly to the tricyclic ring system with the dihedral angle between the two planar systems of 94.93(3)degrees. The nitropyridinyl substituent is located quasi-equatorially with the S center dot center dot center dot N10-C11 angle of 176.92(8)degrees. The nitro group is tilted from the pyridine ring by 128.44(8)degrees. (C) 2016 Elsevier B.V. All rights reserved.
