摘要: 6,7-Dihydroxy-1,2,3,4-tetrahydroisoquinoline is a pharmacologically active alkaloid that can be formed by condensation of dopamine with formaldehyde. We used fluorescence microscopy to study in vitro the uptake and storage this compound sympathetic nerves rat iris. Rats were treated reserpine or methyl ester α-methyl-p-tyrosine order deplete endogenous catecholamine stores. Accumulation was about onetenth norepinephrine. Uptake completely blocked 10-5M desmethylimipramine. These results offer some explanation for sympathomimetric properties alkaloid. Similar expected similar tetrahydroisoquinolines may vivo from catecholamines during ingestion alcoholic beverages.
