Description

• Application: Hordenine is suitable to study the effect of reed canary grass alkoloids on in vito digestibility. It is also suitable for use as a standard to identify endogenous hordenine in ungerminated and germinated barley by HPLC/diode array detection analysis.[1] Hordenine may be used as an analytical reference material and in research on the activities of phenethylamine type alkaloids.
• Biochem/physiol Actions: Hordenine is an alkaloid found in plants, e.g. the roots of germinating barley[2][3] and marine algae.[4] It is a metabolite in tyrosine metabolism, biosynthesized from tyramine by two subsequent N-methylations,[5] it is metabolized by monoamine oxidase.[6] Hordenine is a sympathomimetic and its pharmacological actions are of interest, as it is occasionally found in post race urine samples.[7] Hordenine inhibits melanogenesis by suppression of cyclic adenosine monophosphate (cAMP) production. cAMP is involved in the expression of melanogenesis-related proteins. Hordenine may be used in the inhibition of hyperpigmentation.[1] It is present in barley roots from the first day of seed germination, but is not present in seeds.[8]
