New redox labelling of DNA by an azido group which can be chemically transformed to nitrophenyltriazole or silenced to phenyltriazole was developed and applied to the electrochemical detection of DNA-protein interactions. 5-(4-Azidophenyl)-2-deoxycytidine and 7-(4-azidophenyl)-7-deaza-2-deoxyadenosine nucleosides were prepared by aqueous-phase Suzuki cross-coupling and converted to nucleoside triphosphates (dNTPs) which served as substrates for incorporation into DNA by DNA polymerase. The azidophenyl-modified nucleotides and azidophenyl-modified DNA gave a strong signal in voltammetric studies, at -0.9 V, due to reduction of the azido function. The Cu-catalyzed click reaction of azidophenyl-modified nucleosides or azidophenyl-modified DNA with 4-nitrophenylacetylene gave nitrophenyl-substituted triazoles, exerting a reduction peak at -0.4 V under voltammetry, whereas the click reaction with phenylacetylene gave electrochemically silent phenyltriazoles. The transformation of the azidophenyl ...

A two-stage microreactor continuous flow system allows the handling organic azides safely in small hold-up volumes with immediate conversion in the 2nd microreactor. In the 1st microreactor the azide intermediate is formed by nucleophilic substitution.1 The azide intermediate is submitted to Staudinger hydration with triphenylphosphine in a subsequent 2nd microreactor. Notably, it is possible to work with biphasic systems in microreactors. A phase transfer catalyst moderates the initial reaction with efficient mixing by the microreactor. Production capacity of o-Xylylenediamine (711462) in two subsequent glass microreactors exceeds 1 kg per day with an overall yield of 60%. Work-up and isolation of the potentially hazardous intermediate is completely avoided between reaction steps, saving time, money and offering scale-independent safety levels. back to top ...

Photo-activation of the hydrophobic membrane probe 1, 5 iodonaphthylazide (INA) by irradiation with UV light (310-380 nm) results in the covalent modification of transmembrane anchors of membrane proteins. This unique selectivity of INA towards the transmembrane anchor has been exploited to specifically label proteins inserted in membranes. Previously, we have demonstrated that photo-activation of INA in enveloped viruses resulted in the inhibition of viral membrane protein-induced membrane fusion and viral entry into cells. In this study we show that photo-activation of INA in various cell lines, including those over-expressing the multi-drug resistance transporters MRP1 or Pgp, leads to cell death. We analyzed mechanisms of cell killing by INA-UV treatment. The effects of INA-UV treatment on signaling via various cell surface receptors, on the activity of the multi-drug resistance transporter MRP1 and on membrane protein lateral mobility were also investigated.

Pegylation using heterotelechelic poly(ethylene glycol) (PEG) offers many possibilities to create high-performance molecules and materials. A versatile route is proposed to synthesize heterobifunctional PEG containing diverse combinations of azide, amine, thioacetate, thiol, pyridyl disulfide, as well as activated hydroxyl end groups. Asymmetric activation of one hydroxyl end group enables the heterobifunctionalization while applying selective monotosylation of linear, symmetrical PEG as a key step. The azide function is introduced by reacting monotosyl PEG with sodium azide. A thiol end group is obtained by reaction with sodium hydrosulfide. The activation of the hydroxyl end group and subsequent reaction with potassium carbonate/thioacetic acid yields a thioacetate end group. The hydrolysis of the thioester end group by ammonia in presence of 2,2′-dipyridyl disulfide provides PEG pyridyl disulfide. Amine terminated PEG is prepared either by reduction of the azide or by nucleophilic substitution of

Aryl azides were treated with allenylmagnesium bromide to generate 1,5-disubstituted butynyl 1,2,3-triazoles in a domino fashion, which upon Cu(I) catalyzed 1,3-dipolar cycloaddition with aryl azides afforded novel bis-1,2,3-triazoles in quantitative yields. The final products were analyzed for their antimicrobial activities against a panel of bacterial and fungal strains which revealed the products to be potent antimicrobials.

Tetranitrogen is a neutrally charged polynitrogen allotrope of the chemical formula N 4 and consists of four nitrogen atoms. The tetranitrogen cation is the positively charged ion, N+ 4, which is more stable than the neutral tetranitrogen and is thus more studied. The structure, stability and properties of these molecules have been of great interest to research scientists in the last ten years.[when?] Polynitrogen compounds have been well known and characterized by chemists for many years. Molecular nitrogen (N 2) was first isolated by Daniel Rutherford in 1772 and the azide ion (N− 3) was discovered by Theodor Curtius in 1890. Discoveries of other related nitrogenous allotypes during the twentieth century include the aromatic molecule pentazole and the radical molecule N• 3. However, none of these complexes could be isolated or synthesized on a macroscopic scale like N 2 and azide; it was not until 1999 that a large scale synthesis was devised for a third nitrogen allotrope, the pentazenium ...
The synthesis and full characterisation of bifunctional β -amino acids that have side chains functionalised with terminal azides (S)-4 and (R)-4 or acetylenes 5 and 6 is reported for the first time. The building blocks incorporate a turn-inducing β -segment and a side chain that can be functionalised further, for example, through copper-catalysed Huisgen cycloaddition. Moreover, the corresponding α-amino acids 1 and 3 have been synthesised and characterised. All amino acid building blocks were of high optical purity as demonstrated by derivatisation and subsequent NMR analysis ...

EXPERIMENTAL. The above experiments was conducted on a C80 at a heating rate of 0,5 K/min between room temperature and 280 °C. 76 mg of sample where placed inside a glass liner perfectly fitting the C80 high pressure measurement cell. The C80 was then cooled down, and the permanent decomposition gases were sent to a gas analyzer cell (FTIR).. RESULTS AND CONCLUSIONS. The complex two-step decomposition of o-trifluoromethyl phenyl azide was studied thanks to a combination of calorimetric, pressure, and evolved gas analysis data. Not only thermal and pressure hazards can be assessed, but also the risks linked with the formation of toxic gases - or straightforward information about decomposition mechanisms. For example, the strange silane - based gas detected by the FTIR was assigned to a reaction between the sample and the glass liner.. ...
