(+/-) SKF83959, like many other arylbenzazepines, elicits powerful neuroprotection in vitro and in vivo. The neuroprotective action of the compound was found to partially depend on its D(1)-like dopamine receptor agonistic activity. The precise mecha

The dopamine D2 agonist MCL-524 is selective for the D2 receptor in the high-affinity state (D2high), and, therefore, the PET analogue, [18F]MCL-524, may facilitate the elucidation of the role of D2high in disorders such as schizophrenia. However, th

A series of novel aporphine derivatives were synthesized for initial screening at the 5-HT2 receptor subtypes. Among them, Compounds 11a and 11b were identified as potent 5-HT2C hit ligands with high selectivity over other 5-HT2 receptor subtypes. Mo

The dopamine D(2) receptor exists in two different states, D(2)(high) and D(2low); the former is the functional form of the D(2) receptor and associates with intracellular G-proteins. The D(2) agonist [(3)H]MCL-536 has high affinity for the D(2) rece

Increases in the D2 receptor high affinity state are associated with certain neurological disorders. We synthesized and characterized the high-affinity D2high ligand [(3)H]MCL-536 in competition binding against the D2/3 agonist R-(−)-N-n-propylnora

Background The D1/D2 dopamine agonist apomorphine has poor oral bioavailability, necessitating subcutaneous administration in the treatment of Parkinson's disease (PD). Acute subcutaneous injection is used as rescue therapy from “off” periods, wh

Aporphines are attractive candidates for imaging D2 receptor function because, as agonists rather than antagonists, they are selective for the receptor in the high affinity state. In contrast, D2 antagonists do not distinguish between the high and lo

PET has been used to examine changes in neurotransmitter concentrations in the living brain. Pioneering PET studies on the dopamine system have used D2 and D3 receptor (D2/D3) antagonists such as (11)C-raclopride. However, more recently developed ago
