The reductive dehalogenation of chlorinated propenes was studied with the tetrachloroethene reductive dehalogenase purified from Sulfurospirillum multivorans to obtain indications for a radical mechanism of this reaction. When reduced methyl viologen (MV), which is a radical cation, was applied as
2,3-Dichloropropene (2,3-DCP), a component of commercial fumigants and nematocides, was mixed with [14C]2,3-DCP and given to rats by peroral (p.o.) or intraperitoneal (i.p.) administration. Urine, feces, and expired air were collected over 72 h. Excretion of radioactivity in urine predominated
Drug metabolism and disposition: the biological fate of chemicals, 16(1), 60-68 (1988-01-01)
At the present time, comprehensive metabolism studies of 2,3-dichloro-1-propene (2,3-DCP) have not yet been reported. We have investigated the biotransformation of 2,3-DCP using female Wistar rats in order to elucidate the bioactivation mechanisms. 175 mg/kg, 1,3-14C-2,3-DCP in corn oil was
Ecotoxicology and environmental safety, 30(3), 252-258 (1995-04-01)
Previously the toxicity of 45 heterogeneous environmental chemicals on growth and membrane functions in Saccharomyces cerevisiae and Chinese hamster ovary (CHO) cells (Cascorbi et al., 1993) was examined. In this study the inhibitory effects of the same set of chemicals
In the presence of S9 mix all allylic chloropropenes tested exert considerable indirect mutagenic activity which is most pronounced for 1,2,3-trichloropropene. Lower as well as higher chlorinated derivatives are clearly less mutagenic. Longer than standard incubation time (120 min instead
