When pentachlorophenol, an inhibitor of O-acetyltransferase and sulfotransferase, was added to the mutagenicity assay, a dose-dependent inhibition of N-hydroxy-IQ mutagenicity was observed. 2,6-Dichloro-4-nitrophenol, a more specific inhibitor of sulfotransferase than O- acetyltransferase, did not inhibit the mutagenicity of N-hydroxy-IQ at concentrations which appear to selectively inhibit only bacterial sulfotransferase.
The data suggest that bacterial O-acetyltransferase rather than sulfotransferase mutagenically activates N-hydroxy-IQ.

Two phase II enzymes catalyzing conjugation, i.e. phenol sulfotransferase (P-SULT) and phenol UDP-glucuronosyltransferase (P-UGT), were measured using 1-naphthol as substrate.
Pentachlorophenol (PCP), a commonly used inhibitor of P-SULT, inhibited 1-naphthol conjugation 50% in cell cultures, as well as in microsomal preparations. alpha-Naphthoflavone (ANF) and ellipticine (ELP), both cytochrome P450 (CYP) inhibitors, affected the conjugation of 1-naphthol in different ways; ANF did not affect P-UGT activity in microsomal preparations, but inhibited 1-naphthol conjugation in cell cultures by as much as 90%.

Carcinogenesis. 1994 Oct;15(10):2087-94.

Similar to group II TAM adducts, the formation of hepatic safrole-DNA adducts was inhibited in female ICR mice by both sulfotransferase inhibitors, consistent with the proposal that metabolic alpha-hydroxylation of the ethyl group of TAM followed by sulfate conjugation represented a mechanism of TAM activation.
Exposure to pentachlorophenol (PCP) strongly intensifies the formation of mouse hepatic DNA adducts elicited by oral administration of tamoxifen (TAM), as previously shown by 32P-postlabeling.

Secondary metabolites of PhIP are formed via acetyltransferase (AT) and sulfotransferase (ST) activity; however, which is responsible for its clastogenic effect is unknown.
We used a parental Chinese hamster lung cell line and three sublines transfected with different AT genes to test the clastogenic (i.e., micronucleus-inducing) effects of metabolically activated PhIP and 7,12-dimethylbenz [a] anthracene (DMBA) in the presence and absence of pentachlorophenol (PCP), a ST inhibitor.

The inhibitors used were 2,6-dichloro-4-nitrophenol (DCNP; inhibitor of sulfotransferase (ST)), pentachlorophenol (PCP; inhibitor of both ST and acetyltransferase (AT)) or ranitidine (inhibitor of UDP-glucuronosyltransferase (UDP-GT)).
The inhibitors used were 2,6-dichloro-4-nitrophenol (DCNP; inhibitor of sulfotransferase (ST)), pentachlorophenol (PCP; inhibitor of both ST and acetyltransferase (AT)) or ranitidine (inhibitor of UDP-glucuronosyltransferase (UDP-GT)).

The addition to the mutagenesis assay of pentachlorophenol, an inhibitor of O-acetyltransferase and sulfotransferase, produced a dose-dependent decrease of 1,8-ANP mutagenic activation, whereas 2,6-dichloro-4-nitrophenol, a more specific inhibitor of sulfotransferase than O-acetyltransferase, did not affect the activation of 1,8-ANP to a mutagen at concentrations that selectively inhibit only bacterial sulfotransferase.
Addition of acetyl co-enzyme A (AcCoA) and adenosine 3'-phosphate 5'-phosphosulfate (PAPS), cofactors for O-acetyl-transferase and sulfotransferase respectively, to the test system caused a dose-dependent inhibition of 1,8-ANP mutagenic activation by rat liver cytosol and NADPH, probably due to the formation of highly reactive O-acetoxy and N-sulfate ester derivatives of 1,8-ANP, which react with nucleophilic sites before reaching bacterial DNA.

However, the binding of HNOH-MeIQx to DNA in hepatocytes was independent of sulfotransferase since inhibitors of this enzyme, 2,6-dichloro-4-nitrophenol (DCNP) and pentachlorophenol (PCP), did not diminish DNA binding.
From these inhibition experiments it appears that a major route of binding of HNOH-MeIQx to DNA in hepatocytes is mediated through O-acetyltransferase while a significant portion of HNOH-ABP bound to DNA is catalyzed by sulfotransferase.

18433972 Jeurissen SM, Punt A, Delatour T, Rietjens IM: Basil extract inhibits the sulfotransferase mediated formation of DNA adducts of the procarcinogen 1'-hydroxyestragole by rat and human liver S9 homogenates and in HepG2 human hepatoma cells. Food Chem Toxicol. 2008 Jun;46(6):2296-302. Epub 2008 Mar 16.

Because the inhibition resembled the inhibition by the sulfotransferase inhibitor pentachlorophenol and since the inhibition was not observed in incubations with the direct electrophile 1'-acetoxyestragole it is concluded that the inhibition occurs at the level of the sulfotransferase mediated bioactivation step.
