BW755C, 1-phenyl-3-pyrazolidone (phenidone), toluene-3,4-dithiol (dithiol), 6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline (ethoxyquin) and acetone phenylhydrazone (APH) inhibited both enzyme activities.

Among the antioxidants investigated, vitamin E did not affect, but n-propyl gallate and ethoxyquin exerted a dose-dependent inhibition of PB promotion.
These results are strongly suggestive of an involvement of phospholipase A2, lipoxygenase and cyclooxygenase arachidonic acid metabolic pathways in the mechanisms underlying PB enhancement of hepatocarcinogenesis.

Structurally dissimilar inhibitors of prostaglandin endoperoxide synthetase such as indomethacin, aspirin, 5,8,11,14-eicosatetraynoic acid, ethoxyquin, and meclofenamic acid specifically inhibited FANFT metabolism.

Cumene hydroperoxide-mediated co-oxidation was not prevented by indomethacin or SKF-525A but was blocked by the antioxidants butylated hydroxytoluene, ethoxyquin, and vitamin E.
