Characteristics of membrane receptor binding by 3H-cis-flupenthixol were examined in rat striatum. Using modifications of standard dopamine receptor binding techniques, it was possible to obtain 70% specific binding with 3H-cis-flupenthixol. Association and dissociation rates were very rapid, with equilibrium reached in 2 min and half-time of dissociation being 1 min. Analysis of saturation and competition studies using cis-flupenthixol and spiroperidol indicated that cis-flupenthixol binds to two striatal receptors with apparent KD's of 0.7 and 4.8 nM. It is suggested these represent D1 and D2 dopamine receptors respectively. The further characterization of the properties of cis-flupenthixol binding presented here should enable more detailed studies of multiple dopamine receptors to be designed.
