Abstract
The arylhydrazines 4-methylphenylhydrazine hydrochloride, N′-acetyl-4-methylphenylhydrazine and N′-acetyl-4-hydroxymethylphenylhydrazine (HMPH) were metabolized by ram seminal vesicle prostaglandin(H)synthase (P(H)S) and by cytochrome P-450- and P(H)S-dependent enzymes from mouse lung. Based on the Km-values, the cytochrome P-450 enzymes were the most efficient, suggesting that they would be responsible for the metabolic activation of these compounds in vivo. Cytochrome P-450-dependent metabolism was inhibited by metyrapone and SKF-525A, ruling out the involvement of flavin mono-oxygenase. Agaritine, an arylhydrazide, was poorly metabolized by both systems.
