Application

3-Cyano-7-hydroxycoumarin is closely related to 3-cyano-7-ethoxycoumarin which is used as a fluorometric substrate and inhibitor for cytochrome P-450 enzymes and cytochrome P-450-dependent mixed function oxidases. 3-Cyano-7-hydroxycoumarin may be useful to study the kinetics and substrate specificity of cytochrome P-450s.

Gossypol is a polyphenolic secondary metabolite produced by cotton plants, which is toxic to many organisms. Gossypol's aldehyde groups are especially reactive, forming Schiff bases with amino acids of proteins and cross-linking them, inhibiting enzyme activities and contributing to toxicity.
