Metabolite Identification
Common NameIsomurrayazoline
DescriptionIsomurrayazoline belongs to the class of organic compounds known as phenanthridines and derivatives. These are polycyclic compounds containing a phenanthridine moiety, which is a tricyclic system with two benzene rings joined by a pyridine forming a non-linear skeleton. Hydrogenated derivatives are also included. Isomurrayazoline is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, isomurrayazoline has been detected, but not quantified in, herbs and spices. This could make isomurrayazoline a potential biomarker for the consumption of these foods.
