4-Hydroxycarbazeran is an enzyme probe that belongs to the class of hydralazine. It is metabolized by aldehyde oxidase and sulfation. The kinetics of 4-hydroxycarbazeran has been studied in human lung explants and incubations, with results showing that it is rapidly hydrolyzed by an aldehyde oxidase and sulfation. Carbazarin, a related compound, is also metabolized by this enzyme system. Triclosan has been shown to inhibit 4-hydroxycarbazeran metabolism in vitro. Zoniporide, another related compound, inhibits the activity of aldehyde oxidase and sulfation in vivo.

Applications 4-Hydroxycarbazeran is a metabolite of Carbazeran (C175790), a phosphodiesterase inhibitor drug that exhibits chronictropic and inotropic effects. References Kaye, B., et al.: Xenobiotica., 15, 237 (1985); Shahid, M., et al.: Br. J. Pharmacol., 98, 291 (1989),
