In order to identify new atypical antipsychotic drugs which are more selective for the human dopamine D4receptor than for the human dopamine D2(long) receptor, we tested enantiomer pairs of dopamine agonists and dopamine antagonists on the expressed proteins of these cloned receptors. The (+)-aporphines ((+)-N-propyl-norapomorphine, 11-OH-N-propyl-noraporphine and (+)-apomorphine) bound to the dopamine D4receptor with selectives up to 20 times greater than to the dopamine D2receptor, suggesting that these pharmacologically inactive enantiomers may succeed as atypical neuroleptics.
