N tau-methylhistamine is one of the histamine metabolites. N tau-methylhistamine in plasma and urine is a good parameter for histamine release and the determination of this histamine metabolite is generally less hampered by possible artifacts (due to basophil disrupture a very short half-life time or bacterial production) than determinations of histamine itself.

Deoxybenzoin is used to target immune sensors and xanthine oxidase. It is used for the treatment of gout.

Allitol is a substrate for the production of L-form ketoses and aldoses.
