title: Synthesis and dopamine receptors binding affinity of 2-(3-fluoro-4-hydroxyphenyl)ethylamine and its N-alkyl derivatives.
abstract: The 2-(3-fluoro-4-hydroxyphenyl)ethylamine and its N,N-dialkyl derivatives were synthesized. The affinity of new compounds for dopamine binding sites was measured in a test involving displacement of [3H]SCH 23390 (D-1 selective) and [3H]spiperone (D-2 selective) from homogenized rat striatal tissue. No compound proved effective in displacing [3H]SCH 23390. Two derivatives are selective displacers of [3H]spiperone.
