Beschreibung:
AbstractBesides coumarin, which up to now has remained the most selective substrate for the coumarin 7‐hydroxylase (Coh), 7‐ethoxycoumarin, quinoline, 4‐methylcoumarin, 7‐ethoxy‐4‐methylcoumarin, 7‐ethoxy‐4‐ethylcoumarin, and psoralen are suitable for this enzyme. ‐ The quantification of the suitability of a substrate to selectively measure the coumarin 7‐hydroxylase is achieved by a graphic method. ‐ Requirements for serving as a substrate of the Coh are bicyclic ring systems with an electron rich moiety.
