General description

An extremely selective dopamine D2 receptor agonist (Ki = 9 nM). Commonly used in Parkinson′s Disease models and to reproduce cocaine′s discriminative stimulus effects. Sumanirole has greater than 200-fold selectivity for the D2 receptor subtype versus the other dopamine receptor subtypes in radioligand binding assays. In cell-based assays, sumanirole is a fully efficacious agonist, with EC50 values between 17 and 75 nM. In animals, sumanirole elicits many physiological responses attributed to D2-like receptor function.

The purpose of this study is to demonstrate that sumanirole is a novel dopamine receptor agonist with high in vitro and in vivo selectivity for the D(2) receptor subtype. Sumanirole, (R)-5,6-dihydro-5-(methylamino)-4H-imidazo[4,5,1-ij]quinolin-2(1H)-one (Z)-2-butenedioate (1:1), is unique; it has greater than 200-fold

Dopamine (DA) D3 and D2 receptor mechanisms are implicated in cocaine's abuse-related behavioral effects, but the relative contribution of the two receptor subtypes is only partially characterized. This study investigated the role of D3 and D2 subtype mechanisms by determining
