摘要:
4-(6-Fluoro-1,2-benzisoxazol-3-yl)piperidine has been linked to various arylcarbamates to obtain compounds having affinity for dopamine-D-1 and -D-2, serotonin 5HT(2A) and alpha(1)-adrenoceptors. When Linkers with restricted flexibility are used, the biological activity is reduced indicating that a bended conformation is needed in this series of bioactive molecules. Compounds with a relatively low D-2/5HT(2A) affinity ratio in receptor binding experiments and high affinity for the alpha(1)-adrenoceptors exhibit a pharmacological profile which suggests a preferential effect on the mesocorticolimbic dopaminergic system and an 'atypical' antipsychotic activity.
