NNC-112
NNC-112 is a dopamine D1 receptor antagonist with a Ki of 0.18 nM for rat D1R and a Ki of 18 nM for 5-HT2. NNC-112 competitively inhibits [3H]SCH 23390 binding and blocks dopamine-stimulated adenylate cyclase. NNC-112 blocks D1 receptor-mediated rotational behavior in 6-OHDA-lesioned rats. NNC-112 can serve as a C11-labeled radioligand ([11C] NNC 112) for positron emission tomography imaging. NNC-112 can be used for research on schizophrenia and hypertension.

In Vitro
NNC-112 (20 min) exhibits low affinity for rat striatal dopamine D2 receptors, with a KI of 898 nM[2].
NNC-112 exhibits moderate affinity for 5-HT2 receptors with a KI of 18 nM[2].
NNC-112 (15 min) is a potent competitive inhibitor of dopamine-stimulated adenylate cyclase in rat striatal tissue, with a KI of 2.8 nM[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
NNC-112 (s.c.; 0.5 h before the agonist) selectively antagonizes D1 receptor-mediated rotational behavior in 6-OHDA (HY-B1081A)-lesioned rats with an ED50 of 0.08 mg/kg, without affecting D2-mediated rotation[2].
Pretreatment with NNC-112 (2-2.5 mg/kg; i.v.) produces 77% blockade of [11C]NNC 112 binding in the rat renal cortex, indicating that the PET signal is predominantly driven by specific D1-like receptor binding[4].
