The conversion of 1,3-difluoro-2-propanol to 1,3-difluoroacetone was found to be catalyzed by an NAD (+)-dependent alcohol dehydrogenase, while the defluorination was attributed to microsomal monooxygenase activity induced by phenobarbitone and inhibited by piperonyl butoxide. 4-Methylpyrazole was found to inhibit both of these processes in vitro and when administered (90 mg kg-1 body weight) to rats, 2 hours prior to 1,3-difluoro-2-propanol, eliminated signs of poisoning, prevented (-) erythrofluorocitrate synthesis, and markedly decreased citrate and fluoride accumulation in vivo. 4-Methylpyrazole also appeared to diminish (-) erythrofluorocitrate synthesis from fluoroacetate in vivo, and this was attributed to its capacity to inhibit malate dehydrogenase activity.

TBZ-induced renal injury was reduced by pretreatment with inducers of the microsomal monooxygenase system (sodium phenobarbital, beta-naphthoflavone and 3-methylcholanthrene) and were enhanced by pretreatment with inhibitors of that system (2-diethylaminoethyl-2,2-diphenylvalerate hydrochloride and piperonyl butoxide).

Piperonyl butoxide, a microsomal monooxygenase inhibitor, administered intraperitoneally to mice exerts peak anti-maximal electroshock activity and peak neurotoxicity at 5 and 7h, respectively.

This conclusion was confirmed by showing that the tissue levels of PDMP could be greatly elevated, for a much longer time, when the mice were pretreated with piperonyl butoxide or cimetidine.

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