G L Weber et al.
Toxicology and applied pharmacology, 113(1), 152-158 (1992-03-01)
In vitro studies using rat and human hepatic microsomes have shown that the halogenated hydrocarbon 1,2,3-trichloropropane (TCP) is bioactivated to the direct acting mutagen 1,3-dichloroacetone (DCA). The presence of DCA in microsomal incubations was confirmed by gas chromatography-mass spectrometry. DCA...

Environmental and molecular mutagenesis, 31(4), 390-401 (1998-07-08)
Biotransformation of several structurally related 2B compounds to reactive metabolites was evaluated in the somatic w/w+ assay of Drosophila melanogaster. Chemicals tested were the dichlorinated alkanes dichloromethane (DCM), 1,2-dichloroethane (DCE), and 1,3-dichloropropane (DCP); the thiouracil derivatives 5-methyl, 2-thiouracil (5M2TU), 6-methyl...

Mutation research, 252(1), 17-33 (1991-02-01)
A series of mutation experiments was carried out with Drosophila melanogaster using inhalation exposure. 1,2-Dichloroethane (DCE) and 1,2-dibromoethane (DBE) were active in the sex-linked recessive lethal assay (SLRLT), whereas dichloromethane, dibromomethane, 1,2-dichloropropane and 1,3-dichloropropane were not. Compared to DBE, DCE...

Journal of environmental quality, 33(5), 1647-1652 (2004-09-10)
The effect of soil fumigation on N mineralization and nitrification needs to be better quantified to optimize N fertilizer advice and predict NO(-)(3) concentrations in crops and NO(-)(3) leaching risks. Seven soils representing a range in soil texture and organic...

Biotechnology and bioengineering, 69(3), 235-241 (2000-06-22)
Haloalkane dehalogenase is an enzyme capable of catalyzing the conversion of short-chained (C(2)-C(8)) aliphatic halogenated hydrocarbons to a corresponding primary alcohol. Because of its broad substrate specificity for mono-, di-, and trisubstituted halogenated hydrocarbons and cofactor independence, haloalkane dehalogenases are...

Fundamental and applied toxicology : official journal of the Society of Toxicology, 35(1), 31-48 (1997-01-01)
Previous research showed that acute exposure to dichloromethane (DCM) produced a selective reduction in peak N30 of flash evoked potentials (FEPs) in rats. In contrast, acute exposures to p-xylene or toluene selectively reduced FEP peak N160. The present experiments compared...

Ab initio calculations are reported for three of four possible conformers of 1,3-dichloropropane. The fourth conformer, with Cs symmetry, has a predicted enthalpy difference of more than 1500 cm(-1) from the most stable conformer from each calculation regardless of the...
Distribution of 1,3-dichloropropene and 1,2-dichloropropane in Big Creek watershed.

Treatment of a lysosome-rich fraction from liver with 2-chloroethylethyl sulfide resulted in a dose-dependent release of arylsulfatase. The inclusion of Ca2+ enhanced the enzyme release by approximately 2.3-fold. The enhancing effect of Ca2+, showing an EC50 value of 30 mM...

Cytochrome P450-dependent oxidation and glutathione (GSH)-dependent conjugation are the primary routes of metabolism of haloalkanes. Using rat liver microsomes and cytosol, we investigated the metabolism of two halopropanes found on the U.S. Environmental Protection Agency Contaminant Candidate List, 1,3-dichloropropane (1,3-DCP)...
