The present study describes the pharmacological profile of the putative antipsychotic drug Lu 35-138 ((+)-(S)-3-{1-[2-(1-acetyl-2,3-dihydro-1H-indol-3-yl)ethyl]-3,6-dihydro-2H-pyridin-4-yl}-6-chloro-1H-indole). The in vitro receptor profile of Lu 35-138 revealed high affinity (K(i)=5 nM) and competitive antagonism (K(b)=8 nM) at dopamine D(4) receptors combined with potent

Recent evidence suggests that the dopamine D4 receptor may play a role in schizophrenia, and that the atypical properties of the antipsychotic clozapine may be attributable in part to its antagonistic actions at this receptor. In the present study, clozapine

Biochemical and biophysical research communications, 255(2), 367-370 (1999-03-02)
Dopamine D4-like binding sites are abundant in human cerebral cortex as detected by [3H]nemonapride. The extremely low density of D4 mRNA in human cerebral cortex is inconsistent with the high amount of D4-like binding sites. To investigate the nature of

The discovery of a series of chromeno[3,4-c]pyridin-5-ones with selective affinity for the dopamine D4 receptor is described. Target compounds were tested for binding to cloned human dopamine D2, D3, and D4 receptor subtypes expressed in Chinese hamster ovary (CHO) K-1

The dissolution mechanism of soluble salts of poorly soluble bases can be complex because both the dissolution of the salt and precipitation of the free base can occur depending on the experimental conditions and properties of the molecule. The dissolution
