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.

Toxicity of methanol was enhanced by 4-methylpyrazole, 3-amino-1,2,4-triazole and piperonyl butoxide, and toxicity of formaldehyde was increased by 3-amino-1,2,4-triazole and piperonyl butoxide.
These data indicate that alcohol dehydrogenase, and probably catalase and cytochrome P450 monooxygenase oxidize methanol to formaldehyde, catalase and cytochrome P450 monooxygenase catalyze formaldehyde to formic acid, water and carbon dioxide, and carboxylesterase may have a minor effect.
