Abstract

A set of fourteen 4-{2-[N-propyl-N-alkyl-(or alkylaryl-) amino] ethyl}-2-indolone analogues of dopamine were synthesized in 15 steps and evaluated for their affinities towards the D2 receptor using [3H] sulpiride or [3H] spiperone as radioligands. Six analogues displayed D2 agonist activities comparable (Ki= 450–650 nM) to Ropinirole or SK&F 101468. The functionalized amino side chain introduced in the 4-position can be used to modulate the ...
