Description

NRA-0160 is a selective dopamine D4 receptor antagonist, with a Ki value of 0.48 nM and with negligible affinity for dopamine D2 receptor (Ki: >10000 nM), D3 receptor (Ki: 39 nM), rat 5-HT2A receptor (Ki: 180 nM) and rat α1 adrenoceptor (Ki: 237 nM).

IC50 & Target

Ki: 0.48 nM (D4 receptor), 39 nM (D3 receptor), 180 nM (Rat 5-HT2A receptor), 237 nM (Rat α1 adrenoceptor)[2]

In Vivo

NRA0160 (0.1, 1, or 3 mg/kg, i.p.) has no effect on PCP-induced hyperlocomotion, stereotypy or ataxia in SD rats. NRA0160, at any dose, does not reduce cumulated counts of locomotion and cumulated scores of stereotypy emerging, and has no effect on extracellular glutamate levels and locomotor activity emerged after saline injection[1]. NRA0160 dose-dependently and significantly reverses the effects of MAP on both A9 and Al0 dopamine neurons. NRA0160 is slightly more potent in reversiig the effects of MAP on A10 (ED50 = 1.0 mg/kg) than on A9 dopamine neurons (ED50 = 1.3 mg/kg). NRA0160 reverses the effect of AP0 on both A9 and A10 dopamine neurons. ED50 values for the effects of NRA0160 on APO-induced inhibition of A9 and A10 dopamine neurons are 1.3 mg/kg and 0.5 mg/kg, respectively[2].

Methamphetamine (MAP, 1 mg/kg, iv) or apomorphine (APO, 40 μg/kg iv.) and incremental doses of NRA0160 or G745870 (the starting dose is 0.1 mg/kg with sequential doses of 0.2, 0.7 and 2 mg/kg) are administered every 2-3 min (drug-induced changes usually reached their plateaus in 2-3 min) via an i.v. catheter implanted in the femoral vein of rats. Drug-induced changes (after reaching plateau) in neuronal activities which are plotted as percent changes from the preinjection baseline rate, are recorded over a 5 min period and defined as 100%. The % inhibition is calculated and ED50 values are determined. The ED50 values are analyzed by fitting it to the four parametric logistic functions, using non-linear least square regression (-) Apomorphine hydrochloride, methamphetamine HCl and L 745870 3HCl are dissolved in 0.9% saline with the addition of 0.1% ascorbic acid for apomorphine. NRA0160 is dissolved in a minimal amount of 0.5N HCl and distilled water for injection, then titrated is with 0.5N NaOH to a final pH of 5.
