Mutagens
Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes. (See all compounds classified as Mutagens.)

MASS SPECTRAL STUDIES USING (18)O2 SHOWED THAT (18)O-CO WAS PRODUCED INDICATING THAT OXYGEN WAS INCORPORATED DURING THE REACTION. A PRIMARY DEUTERIUM ISOTOPE EFFECT WAS OBSERVED FOR CONVERSION OF DICHLOROMETHANE TO CARBON MONOXIDE BOTH BY LONG-EVANS RAT HEPATIC MICROSOMAL FRACTIONS & BY STANNOUS PHOSPHATE MODEL SYSTEM. INCUBATION OF DIBROMOMETHANE IN THE MODEL SYSTEM IN THE PRESENCE OF 3,4-DIMETHYLANILINE RESULTED IN FORMATION OF 3,4-FORMOXYLIDIDE, SUPPORTING THE INTERMEDIACY OF A FORMYL HALIDE. A MECHANISM FOR THE METABOLISM OF DIHALOMETHANES TO CARBON MONOXIDE IS PROPOSED.

Halogenated methanes, in particular the brominated homologs, including dibromomethane and tribromomethane were subjected to biochemical decomposition in vitro by the cytochrome p450 rich fraction of the monooxygenase liver system. No significant contribution of GSH addition to the overall rate of metabolism of the halogenated methanes could be observed.

Treatment of Sprague-Dawley rats with sodium phenobarbital (50 mg/kg in 0.9% saline for 4 days) or 3-methylcholanthrene (20 mg/kg in corn oil for 2 days) resulted in increased metabolism of dibromomethane (3 m mol/kg) to carbon monoxide.

Biotransformation of dihalomethanes leads to dehalogenation & end product is carbon monoxide. In the case of dichloromethane the carbon monoxide appears to arise from formyl halide. This intermediate, as an alternative to losing carbon monoxide, can covalently bind to cellular protein or lipid. The involvement of nonmicrosomal enzymes in dihalomethane biotransformation leads to prodn of formaldehyde & halide. A necessary step is the reaction of dihalomethane with glutathione, which results in loss of one halide. The resulting halomethylglutathione is postulated to undergo nonenzymatic hydrolytic dehalogenation leaving hydroxymethylglutathione. The next step would result in the release of the hydroxymethyl group as formaldehyde. Alternatively it has been shown that in the presence of formaldehyde dehydrogenase & NAD /nicotinamide-adenine dinucleotide/ formic acid can be formed. /Dichloromethane/
