In the title compound, C(16)H(16)N(2)O(2), the N'-acetyl-acetohydrazide group is approximately planar (r.m.s. deviation = 0.018 Å for the eight non-H atoms) and makes dihedral angles of 81.92 (6) and 65.19 (6)° with the terminal phenyl rings. The phenyl rings form a dihedral angle of 62.60 (7)°. In the crystal, mol-ecules are linked into sheets lying parallel to (001) by N-H⋯O and C-H⋯O hydroge...

In the title compound, C(9)H(10)N(2)O(2)·H(2)O, the mol-ecular skeleton of the acetohydrazide mol-ecule is nearly planar [within 0.014 (1) Å]. The mol-ecule adopts a trans configuration with respect to the C=N bond, while the side chain is slightly twisted away from the attached ring, forming a dihedral angle of 9.975 (8)°. The crystal packing exhibits a three-dimensional network composed from ...

The formula unit of the title mol-ecular complex, 2C(16)H(16)N(2)O(3)·C(16)H(16)N(2)O(2), consists of two (E)-N'-[1-(2-hy-droxy-phen-yl)ethyl-idene]-2-phen-oxy-acetohydrazide mol-ecules and one mol-ecule of 2,2'-(1,1'-azinodiethyl-idyne)diphenol, with the latter located on a crystallographic inversion center. The acetohydrazide mol-ecules are linked into a supermolecular chain along the c axis ...

In the title compound, C14H16N6O2, the dihedral angles formed by the mean plane of the acetohydrazide group [maximum deviation 0.0629 (12) Å] with the pyrazole and pyridine rings are 81.62 (6) and 38.38 (4)° respectively. In the crystal, mol-ecules are connected by N-H⋯O and O-H⋯N hydrogen bonds into supra-molecular chains extending parallel to the c-axis direction.

Postherpetic neuralgia (PHN) represents a potentially debilitating and often undertreated form of neuropathic pain that disproportionately affects vulnerable populations, including the elderly and the immunocompromised. Varicella zoster infection is almost universally prevalent, making prevention of acute herpes zoster (AHZ) infection and prompt diagnosis and aggressive management of PHN of cri...

Rhizobium etli mutants unable to grow on asparagine as the nitrogen and carbon source were isolated. Two kinds of mutants were obtained: AHZ1, with very low levels of aspartase activity, and AHZ7, with low levels of asparaginase and very low levels of aspartase compared to the wild-type strain. R. etli had two asparaginases differentiated by their thermostabilities, electrophoretic mobilities, ...

In the title compound C(10)H(11)N(3)O, the mean plane of the indole ring system (r.m.s. deviation 0.0131 Å) subtends a dihedral angle of 87.27 (5)° to the almost planar acetohydrazide substituent (r.m.s. deviation 0.0291 Å). In the crystal, bifurcated N-H⋯(O,N) and N-H⋯N hydrogen bonds involving the pyrrole N-H grouping combine to form zigzag chains along a. Additional N-H⋯O contacts from the h...

We study a circuit where a mesoscopic Josephson junction ~JJ! is embedded in an environment consisting of a large bias resistor and a normal-insulator-superconductor ~NIS! junction. The effective Coulomb blockade of the JJ can be controlled by the tunneling current through the NIS junction leading to transistor-like characteristics. We show using phase correlation theory and numerical simulatio...

New 3(2H)-pyridazinone derivatives containing a N'-benzyliden-acetohydrazide moiety at position 2 were synthesized. The structures of these newly synthesized compounds were confirmed by IR, 1H NMR, and MS data. These compounds were tested for their antibacterial, antifungal, antimycobacterial, and cytotoxic activities. The compounds 2-[4-(4-chlorophenyl)-6-(morpholin-4-yl)-3-oxo-(2H)-pyridazin-...
