The compound aquanitrate-small ka, CyrillicObis[2-(2-pyridy)-imin-small ka, CyrillicN-N-(2-thiazin-small ka, CyrillicN-2-y)thiazidine]cbat() nitrate has been isolated and characterized by single crystal X-ray diffraction, IR spectroscopy, UV-Vis-NIR diffuse reflectance and magnetic susceptibility measurements. The environment around the cobalt atom may be described as a distorted octahedral geo...

In the title compound, C(5)H(8)N(3) (+)·Cl(-), the cation and the anion lie on a mirror plane and are hydrogen bonded in a three-dimensional network via the H atoms of the two hydrazine N atoms. The pyridine N atom is protonated and hydrogen bonded to the terminal hydrazine N atom.

We controlled the morphologies of zinc oxide (ZnO) nanostructures on single-walled carbon nanotube electrodes by an electrochemical deposition method and investigated the dependence of the electrocatalytic characteristics toward hydrazine on the different morphologies. ZnO nanorods provided high electrocatalytic activity with unique electrochemical behaviours, associated with the H(+) ion gener...

I would like to comment briefly on the issue raised by Dr. Wheeler (1) with reference to the review by Tisdale (2) on the use of hydrazine sulfate for the treatment of patients with cancer cachexia. The point, in my opinion, is not whether or not hydrazine sulfate was effective in the clinical trials reported by the authors but whether its use in that context was appropriate. We know, in fact, ...

We established an in vitro assay for the addition of glycosyl-phosphatidylinositol (GPI) anchors to proteins using procyclic trypanosomes engineered to express GPI-anchored variant surface glycoprotein (VSG). The assay is based on the premise that small nucleophiles, such as hydrazine, can substitute for the GPI moiety and effect displacement of the membrane anchor of a GPI-anchored protein or ...

In the title complex, [Cu(C13H11N2O)Cl(C6H8N2)], the Cu(II) atom adopts a distorted tetra-hedral geometry being coordinated by the phenolic O atom and the azomethine N atom of the Schiff base ligand N-salicyl-idene 2-amino-pyridine, and by the 2-amino-pyridine N atom and a Cl atom. The pyridyl N atom of the Schiff base and the imino N atom of the 4-methyl-pyridine-2-yl-imino ligand are not invo...

In the title thio-semicarbazone, C11H15N3S, the p-tolyl-N-H and imino-N-H groups are anti and syn, respectively, to the central thione-S atom. This allows for the formation of an intra-molecular p-tolyl-N-H⋯N(imino) hydrogen bond. The mol-ecule is twisted with the dihedral angle between the p-tolyl ring and the non-hydrogen atoms of the N=CMe2 residue being 29.27 (8)°. The crystal packing featu...

We demonstrate a fairly general method for identification of NMR absorption lines of macromolecues extracted from microorganisms, based on nuclear Overhauser effects (NOE). Several NOE in tRNA are observable between resolved imino proton resonances and ring carbon resonances that are either C(2) protons of adenine or C(8) protons of adenine or guanine. Yeast tRNAPhe was deuterated at the purine...

keeping in view the promising potential of carbonic anhydrase inhibitor based antimicrobials and enhancement of carbonic anhydrase inhibitory activity by metal complexes of sulfonamides, with an aim to develop better antimicrobial agents we have attempted investigation of antimicrobial activity of metal complexes of 4-(2'-hydroxy phenyl imino) phenyl sulphonamide. sulfanilamide was taken a...
