Oxidation of synephrine by type A and type B monoamine oxidase
Experientia, 1979Synephrine (SP) was found to be a substrate for monoamine oxidase (MAO) in rat brain mitochondria, showing the Km and Vmax values of 250 microM and 32.6 nmoles/mg of protein/30 min respectively. The inhibition studies showed that the SP oxidation was carried out by both type A and type B MAO and a major part of the activity was due to type A MAO.

Adrenergic Activities of Octopamine and Synephrine Stereoisomers
1988Both m-OA and p-OA are known to occur in the mammalian sympathetic nervous system where they are taken up in NA nerve terminals, accumulated in storage vesicles and released together with NA (Ibrahim et al, 1985). It is probable that both amines are released with NA as co-transmitters as proposed for p-0A by Axelrod and Saavedra (1977).

[Pharmacokinetics and metabolism of 3H-synephrine (author's transl)].
Arzneimittel-Forschung, 1979The physiological disposition of 1-(4-hydroxyphenyl)-2-methylamino-ethanol-tartrate (synephrine, Sympatol) in man had not been investigated to date. Therefore, we studied pharmacokinetics and metabolism of tritiated synephrine in man. Following short i.v. infusion in six patients about 80% of the administered radioactivity was recovered in urine.
