Mutagenic activation of 2-amino-3-methylimidazo[4,5-f]-quinoline (IQ) and 2-amino-3,4-dimethylimidazo[4,5-f]-quinoline (MeIQ) by subcellular fractions and cells isolated from small intestine, kidney and liver of the rat.

Abstract:

:The mutagenic activity of the pyrolysis products 2-amino-3-methyl-imidazo[4,5-f]-quinoline 2-amino-3,4-dimethylimidazo[4,5-f]-quinoline in Salmonella typhimurium TA98 using rat intestinal and renal subcellular fractions as activation systems was approximately 1 and 5 revertants per nmol, respectively. This was 1,000 times less than the activity with a subcellular fraction from rat liver. The mutagenic activity of both compounds was considerably increased using intestinal, renal and hepatic preparations isolated from PCB (Aroclor 1254)-pretreated rats, compared to preparations from control animals. In addition, both compounds displayed a moderate direct-acting mutagenic activity at concentrations above 10(-5) M. Isolated cells from small intestine, kidney and liver incubated in nucleopore chambers were able to convert both compounds into products which mutated bacteria outside the chambers. The concentrations of chemicals required to yield responses of a similar magnitude were approximately 3 orders of magnitude higher in the intestinal and renal systems compared to the hepatic system. The formation of metabolites mutagenic for Salmonella typhimurium by hepatic subcellular and cellular systems was shown to be superior to the respective intestinal and renal systems.
