Nocardia cultures, isolated from soil by use of n-paraffins as the sole carbon source, have been shown to bring about significant oxidation of several methyl-substituted mono- and dicyclic aromatic hydrocarbons. Oxygen uptake by washed cell suspensions was not a reliable indicator of oxidation. Under co-oxidation conditions in shaken flasks, o- and p-xylenes were oxidized to their respective mo...

In the title compound, [Ni(C(17)H(14)N(3)S(2))(2)]·2C(3)H(7)NO, the Ni atom (site symmetry ) is N,S-chelated by two deprotonated Schiff base anions in a distorted square-planar geometry. The dihedral angle between the aromatic ring planes within the ligand is 86.37 (13)°. In the crystal structure, an N-H⋯O hydrogen bond links the complex to the dimethyl-formamide solvent mol-ecule.

THE TITLE COMPOUND [SYSTEMATIC NAME: 14,15-dihy-droxy-7,7-dimethyl-13-(propan-2-yl)tricyclo-[9.4.0.0(3,8)]penta-deca-1(11),3(8),9,12,14-pentaen-4-one], C(20)H(24)O(3), is a new icetexane diterpenoid which was isolated from the roots of Premna obtusifolia (Verbenaceae). The mol-ecule has three fused rings: a cyclo-hexenone, a central cyclo-heptene and a benzene ring. The cyclo-hexenone ring is i...

In the title complex, [Pt(C(6)H(4)NO(2))Cl(C(2)H(6)OS)], the Pt(II) ion is in a distorted square-planar environment defined by the N and O atoms from the chelating pyridine-2-carboxyl-ate (pic) anionic ligand, one S atom of the dimethyl sulfoxide mol-ecule and one Cl ion. The complex is disposed about a crystallographic mirror plane parallel to the ac plane passing through all the atoms of the ...

Laboratory bioassays were done to determine the level of resistance to endosulfan, cypermethrin, deltamethrin, methamidophos, profenofos and chlorpyrifos in field populations of cabbage aphid, Brevicoryne brassicae (L). Comparison between Multan and Kabirwala strains revealed that the level of resistance in Multan strain was comparatively higher to methamidophos, profenofos and chlorpyrifos as ...

2-phosphonobutane-1,2,4-tricarboxylic acid is(pbtc) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. phosphonocarboxylates as a member of organophosphorus compounds have c-p and p-o bonds in their structures. pbtc is mainly used as carbonate scale inhibitor (caco3), sulphate scale inhibitor (caso4), corrosion inhibitor of low alloyed steel, eff...

The promyelocytic HL60 cell can be differentiated with dimethyl sulphoxide or dibutyryl cyclic AMP leading to the appearance of fMetLeuPhe receptors on the cell surface. G-protein-stimulated polyphosphoinositide phosphodiesterase (PPI-pde) activity was assessed in membranes prepared from both differentiated and non-differentiated HL60 cells. Both the extent of the response and the rank order of...

The title compound, C(25)H(38)O(5), was formed by the reaction of dimethyl 2-butyl-malonate and 2,6-di-tert-butyl-4-[(dimethyl-amino)meth-yl]phenol. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds into chains along [010].
