Malathion (S-(1, 2-dicarboethoxyethyl) O, O-dimethyl phosphorodithioate) is one of the organophosphate pesticides comprehensively used in agriculture fields throughout the world. In spite of widely used, little information are available about DNA damage in aquatic organisms. Therefore, the present study carried out to investigation of DNA damage induced by malathion in Cyprinus carpio (Pisces: ...

The methylating capability of methamidophos, assayed by the formation of [7-14C]methylguanine in mouse liver, was investigated using a 14C-insecticide labelled at the O--CH3 group. Following i.p. administration of the toxicant, [7-14C]methylguanine could be isolated from liver nucleic acids of treated mice. The amount of 14C-label reached its maximum 6 h following administration of the insectic...

In the title compound, [Gd(C(15)H(11)O(2))(3)(C(17)H(18)N(2))], the Gd(III) atom is coordinated by six O atoms from three β-diketonate ligands and two N atoms from a chiral ligand L(S),(S)-(+)-7,7-dimethyl-3-(2-pyrid-yl)-5,6,7,8-tetra-hydro-6,8-methano-iso-quinoline, in a coordination geometry best described as distorted square-anti-prismatic.

The title compound, C(10)H(14)O(2), synthesized by reduction of 4,7-dimethyl-2-benzofuran-1,3-dione, crystallizes with two independant mol-ecules in the asymmetric unit, both showing an intra-molecular O-H⋯O hydrogen bond. The crystal packing is stabilized by O-H⋯O hydrogen bonds.

In the title compound, C(14)H(14)ClN(3)OS, the 4,6-dimethyl-pyrimidine ring and the chloro-benzene ring subtend a dihedral angle of 80.0 (2)°. The length of the Csp(2)-S bond is significantly shorter than that of the Csp(3)-S bond. The crystal structure is stabilized by inter-molecular N-H⋯O, C-H⋯O and C-H⋯N hydrogen bonding, and C-H⋯π inter-actions.

The Zn(II) atom in the title compound, [Zn(C(8)H(7)N(3)O(2)S)(C(12)H(8)N(2))]·2C(2)H(6)OS·H(2)O, is N,N'-chelated by the N-heterocycle and N,O,S-chelated by the deprotonated Schiff base in a distorted square-pyramidal enviroment. Hydrogen bonds link the mononuclear mol-ecule, the water and the dimethyl sulfoxide (DMSO) mol-ecules into a linear chain motif. One DMSO mol-ecule is disordered over ...

In the mononuclear title complex, [Zn(C(10)H(8)N(2))(2)(C(2)H(6)OS)(2)](C(24)H(20)B)(2)·C(2)H(6)OS, the Zn(II) ion is coordinated by four N atoms of two bidentate 2,2'-bipyridine mol-ecules and by the O atoms of two cis-disposed dimethyl sulfoxide mol-ecules in a distorted octa-hedral geometry. The S atom and the methyl groups of one of the coordinated dimethyl sulfoxide mol-ecules are disorder...

The title compound, cis,fac-dichloridotetra-kis(dimethyl sulfoxide)-κ(3)S,κO-ruthenium(II), [RuCl(2)(C(2)H(6)OS)(4)], was obtained from newly synthesized ruthenium complexes of 3-amino-2-chloro-pyridine. The Ru atom has a distorted octa-hedral coordination with two cis-oriented chloride ligands and four dimethyl sulfoxide ligands. Three of the sulfoxide ligands are S-bonded in a fac configurati...

The title compound {systematic name: (2S,3R)-ethyl 3-[(3aS,4R,6S,6aS)-6-tert-butyl-dimethyl-silyl-oxy-2,2-dimethyl-per-hydro-furo[3,4-d][1,3]dioxol-4-yl]-2-nitro-3-[(S)-tetra-hydro-2H-pyran-2-yl-oxy]propanoate}, C(23)H(41)NO(10)Si, is the product of the Henry reaction of 1-O-tert-butyl-dimethyl-silyl-2,3-O-isopropyl-idene-α-d-lyxo-penta-dialdo-1,4-furan-ose with ethyl nitro-acetate and the subs...
