The N-OH-AAF-induced increase was partially blocked by pretreatment with pentachlorophenol, an inhibitor of sulfotransferase activity, in both male and female F-344s.

Pentachlorophenol, an inhibitor of acetyltransferase activity, suppressed the activation of 6-aminochrysene in liver microsomes from phenobarbital-treated rats and from human samples HL-4, HL-13 and HL-18 but not HL-16.
Inclusion of purified rat epoxide hydrolase to the reconstituted system containing rat and human P4501A enzymes caused a decrease in the rates of 6-aminochrysene activation.(ABSTRACT TRUNCATED AT 400 WORDS)
