Background and purpose: Despite growing list of antifungal agents, their clinical value has been limited by their relatively high risk of toxicity, the emergence of drug resistance, and insufficiencies in their antifungal activity. This situation has led to an ongoing search for potent broad spectrum antifungal agents with low side effects, which can be administered both orally and parenteral...

The synthesis and characterization of a series of RM(DBPh2)2(H2O) complexes (M = Co and Rh) and the X-ray structure of the dinuclear n-PrRh(DH)(DBPh2) 2 (1) obtained by recrystallization of nPrRh(DBPh2)2(H2O) in non coordinating solvent are reported. The crystals of (1) are built up by neutral centrosymmetric dinuclear n-PrRh(DH)(DBPh2) 2 units and CH2Cl2 crystallization molecules in the ratio ...

In the title compound, [Ni(HCOO)(2)(C(7)H(8)N(2)O)(2)], the Ni atom is six-coordinated by four N atoms from two oxime ligands and by two O atoms from two formate ions in a distorted octa-hedral geometry, with the oxime-N atoms mutually trans. The mol-ecular conformation is stabilized by intra-molecular O-H⋯O hydrogen bonds.

The title compound, C(6)H(6)N(2)O(2), was obtained as a product of an in vitro study of the metabolism of benzofuroxan. The molecule exhibits a amphi configuration of the oxime groups C=N-OH. One oxime group is involved in the formation of a strong intra-molecular O-H⋯N hydrogen bond, while another links mol-ecules into zigzag chains along the c axis via inter-molecular O-H⋯N hydrogen bonds.

11H-Indeno[1,2-b]quinoxalin-11-one oxime (IQ-1) and tryptanthrin-6-oxime are potent c-Jun N-terminal kinase 3 (JNK-3) inhibitors demonstrating neuroprotective, anti-inflammatory anti-arthritic activity. However, the stereochemical configuration of carbon–nitrogen double bond (E- or Z-) in these compounds was so far unknown. In this contribution, we report results determination solid state by si...

The title compound, [U(C(5)H(7)O(2))(2)O(2)(C(6)H(6)N(2)O)], exhibits a penta-gonal-bipyramidal coordination geometry around the U(VI) atom, involving two bidentate acetyl-acetonate ions and the pyridine ring of the pyridine-4-carbaldehyde oxime ligand. Hydrogen bonds exist between the OH group of the pyridine-4-carbaldehyde oxime ligand and the two O atoms of the acetyl-acetonate ions.

The title compound, C27H27N5O3 H2O, is built up from pyrazolinone, phenyl and acetophenone oxime moieties. The 2-phenyl substituent is nearly perpendicular to the pyrazolinone ring, with a dihedral angle of 87.66 (1) . The acetophenone oxime moieties are twisted out of the pyrazolinonering plane by 47.04 (1) . The molecules in the crystal pack in an antiparallel fashion and are held together by...

The title compound, C(10)H(12)N(4)O(2), features an intra-molecular N-H⋯N hydrogen bond formed between the imine NH and oxime N atoms. The oxime group and the amide C=O bond are anti to each other. In the crystal, mol-ecules are connected by O-H⋯O hydrogen bonds into supra-molecular zigzag chains along the c axis.

A wide range of new oxime-based photochromic diarylethenes of the cyclopentenone series have been synthesized. Their spectral properties have been investigated in detail upon UV/vis light irradiation in acetonitrile solution, and distinct correlations between photochromic characteristics and substance structures are revealed. It was found that the introduction of an oxime group into the cyclope...
