12-Fluoro-5-methylchrysene, which has a fluorine atom at a peri position, is less carcinogenic toward mouse skin than is 5methylchrysene. To determine the basis for this observation, we identified metabolites of 12-fluoro-5-methylchrysene formed by rat liver in vitro, and used these as standards to study the metabolism of [3H]-12-fluoro-5-methylchrysene in mouse liver in vitro and in mouse epid...

In the title compound, [Ni(C(8)F(4)O(4))(C(5)H(5)N)(2)(CH(4)O)(2)](n), the Ni(II) ion is located on an inversion center and is coordinated by four O atoms [Ni-O = 2.079 (4) Å] from two tetra-fluoro-terephthalate ligands and two methanol mol-ecules, and by two N atoms [Ni-N = 2.127 (4) Å] from two pyridine ligands in a distorted octa-hedral geometry. The Ni(II) ions are connected via the tetra-f...

Nucleotide excision repair (NER) is a major repair pathway that recognizes and corrects various lesions in cellular DNA. We hypothesize that damage recognition is an initial step in NER that senses conformational anomalies in the DNA caused by lesions. We prepared three DNA duplexes containing the carcinogen adduct N-(2'-deoxyguanosin-8-yl)-7-fluoro-2-acetylaminofluorene (FAAF) at G(1), G(2) or...

UNLABELLED Studies in animal models and epileptic patients have led to the suggestion that the basal ganglia (BG) are involved in seizures. PET with 6-18F-L-3,4-fluorodihydroxyphenylalanine (18F-fluoro-L-DOPA) has recently demonstrated a reduction of striatal dopamine uptake in drug-resistant epileptic patients with ring chromosome 20 (r20) using a multiple-time graphical analysis. The aim of t...

In the title complex, {[Cu(SiF(6))(C(11)H(8)N(2)O)(2)]·2H(2)O}(n), the Cu(II) atom adopts an N(4)F(2)-octa-hedral coordination geometry with four pyridine N atoms in the equatorial sites and two F atoms in the axial sites. The di-3-pyridyl-methanone and hexa-fluoro-silicate ligands act as bidentate ligands, linking symmetry-related Cu(II) atoms. Water mol-ecules form O-H⋯O and O-H⋯F hydrogen bo...
