Helen Hurst et al.
Reproductive toxicology (Elmsford, N.Y.), 28(4), 503-510 (2009-08-04)
The chick micromass culture system has advantages over the validated rat system - ready availability and non-culling of the donor parent - but needs to give comparable results. This study confirmed comparability and the ability to extend the system to

Hepatocytes were isolated and cultured from untreated rats and rats treated with isoniazid to induce cytochrome P4502E1. Isoniazid selectively increased p-nitrophenol hydroxylase activity in 2-h cultures, and increased the toxicity of both 1,3- and 2,3-dichloropropanol. Isoniazid also increased the rate

Cross-aldol reactions of carbonyl compounds were achieved by the catalysis of SmI(2) or SmI(3), together with molecular sieves, at ambient temperature. 1,3-Dichloroacetone and 1-chloroacetone can be used as acceptor substrates in the cross-aldol reactions with donor substrates such as acetone

Studies were conducted to assess the in vitro toxicity of three chloropropanones: monochloropropanone (MCP), 1,1-dichloropropanone (1,1-DCP), and 1,3-dichloropropanone (1,3-DCP). Chloropropanones reacted directly with reduced glutathione (GSH) in sodium phosphate buffer at pH 7.4. All chloropropanones were cytotoxic to suspensions of

Toxicity of compounds requiring glutathione for detoxification, thiol content and synthesis were determined in 24-h rat hepatocytes cultured in medium containing different concentrations of the sulphur amino acids. Glutathione synthesis was determined following prior depletion of glutathione with diethylmaleate. L-15

Monohaloacetaldehydes and monohalooxiranes are early oxidative metabolites of several carcinogenic haloaliphatics. Since monohaloacetaldehydes and supposedly monohalooxiranes react with adenines to form fluorescent 1,N6-ethenoadenines, it was hypothesized that in vitro metabolic systems that produce an ethenoadenine-forming metabolite could be assayed quantitatively

It is crucial to explore the source, formation process and interdependence of disinfection byproducts (DBPs) to reduce their risk on public health. In this investigation, a source water was chlorinated to evaluate the initial formation rates and the maximum yields

A large number and variety of compounds are formed in the process of chlorinating drinking water. The classes of compounds formed include trihalomethanes, haloacetic acids, haloacetonitriles, halophenols, and halopropanones. Many of the compounds have been shown to be toxic and
Effects of pH and temperature on the degradation of chloroacetones that are mutagenic.

Several chlorinated acetones have been identified in drinking water and these, as well as a number of chlorinated acroleins, are produced by chlorination of humic acid solutions. Many of these chlorinated compounds and the brominated acrolein analog were positive in

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

1,3-Dichloropropanone (1,3-DCP) has been identified as a by-product of the chlorination of water and thus a potential contaminant in drinking water. Since little was known of its oral toxicity, subchronic exposure studies were conducted with male and female Sprague-Dawley rats

A number of polyamine (PA) derivatives of thiosemicarbazone of 1,3-dichloroacetone (TDA) have been prepared and their effect on growth in vivo of tumorigenic but not metastatic cell strain (LY-R) of mouse lymphoma L5178Y has been investigated. Polyamine derivatives of TDA

1. This study has examined the ability of dichloropropanols, haloalcohols and their putative metabolites to deplete glutathione when incubated with liver fractions obtained from untreated and differentially induced rats. 2. 1,3-Dichloropropan-2-ol and 2,3-dichloropropan-1-ol (0-1000 microM) both depleted glutathione in a

Relaxin-3 is a highly conserved two-chain neuropeptide that acts through its endogenous receptor the Relaxin Family Peptide-3 (RXFP3) receptor. The ligand/receptor system is known to modulate several physiological processes, with changes in food intake and anxiety-levels the most well studied
