The rationale for melanoma specific dihydroxybenzene containing antitumor agents is based in part upon the ability of the enzyme tyrosinase to oxidize these pro drugs to toxic intermediates. In situ tyrosinase activity was demonstrated to be affected by both cell

We noted rapid breakdown at 4 degrees and 20 degrees C of dopamine (DA) (but not of (nor)epinephrine and epinine) in pig plasma, but not in human plasma. The enzyme responsible appears to be a semicarbazide-sensitive amine oxidase (SSAO) because

An assay of norepinephrine (NE), epinephrine (E), dopamine (DA), normetanephrine (NE) and metanephrine (MN) based on high-performance liquid chromatography (HPLC) in combination with atmospheric pressure chemical ionization mass spectrometry (APcI-MS) is described. The catecholamines and metanephrines were extracted from urine
