Carbon nanotube electrodes were modified with ferrocene and laccase using two different click reactions strategies taking advantage of bifunctional dendrimers cyclopeptides. Using diazonium functionalization the efficiency oxime ligation, combination both multiwalled carbon surfaces or cyclopeptides allows access to a high surface coverage in order 50 nmol cm–2, 50-fold increase compared classi...

In the title compound, C(13)H(11)ClN(2)O(3), the nine-membered bicycle includes an oxime group having the C=N group in an E configuration. The isoxazole ring is almost planar [r.m.s. deviation = 0.0056 Å]; the dihedral angle between the isoxazole and 4-chloro-phenyl ring is 75.60 (5)°. In the crystal, inter-molecular O-H⋯N(isoxazole) hydrogen bonds give rise to chains running along the b axis.

The biosynthesis of the tyrosine-derived cyanogenic glucoside dhurrin involves N-hydroxytyrosine, (E)- and (Z)-p-hydroxyphenylacetaldehyde oxime, p-hydroxyphenylacetonitrile, and p-hydroxymandelonitrile as intermediates and has been studied in vitro using a microsomal enzyme system obtained from etiolated sorghum (Sorghum bicolor [L.] Moench) seedlings. The biosynthesis is inhibited by carbon m...

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.
