It was demonstrated that the inhibitors of microsomal monooxygenases, piperonyl butoxide, and of nonspecific esterases, butifos, significantly increase the sensitivity of the resistant population to permetrin.

The insecticidal activity of Tomadol 23-1 was synergized by coapplication with a sublethal amount of piperonyl butoxide, indicating the involvement of cytochrome P450 microsomal monooxygenases in insect metabolism of AEO surfactants.

(R)-(+)-Pulegone, the major monoterpene component of the abortifacient mint oil, pennyroyal oil, is metabolized by hepatic microsomal monooxygenases of the mouse to a hepatotoxin.
Furthermore, two inhibitors of cytochromes P-450, cobaltous chloride and piperonyl butoxide, block toxicity.

Cytochrome P450-dependent monooxygenase activity (methoxyresorufin O-demethylase) was consistently observed in midgut preparations, and formation and detection of the sulfone metabolite in the same midgut preparations was also NADPH-dependent and inhibited by piperonyl butoxide.
In vitro metabolism results indicate microsomal monooxygenases are responsible for the conversion of fipronil to its sulfone form in the European corn borer.

Renal cortical accumulation of phenobarbital in rats was also inhibited by piperonyl butoxide.
