1.Effects of a range of dopamine receptor agonists and antagonists on ethanol intake in the rat.
Silvestre JS;O'Neill MF;Fernandez AG;Palacios JM Eur J Pharmacol. 1996 Dec 30;318(2-3):257-65.
The aim of this study was to assess the effects of a range of dopaminergic agents on consumption of an ethanol solution (10% ethanol, 3% glucose) in rats. A two-bottle, free-choice paradigm was used following induction of ethanol consumption and preference in standard laboratory rats. The model used provides a robust and reliable level of ethanol oral administration in normal laboratory rats. Both ethanol intake and preference were reduced by a dopamine D1 receptor partial agonist, SFK 38393 ((+/-)-1-phenyl-2,3,4,5-tetrahydro-(1H)-3-benzazepine-7,8-diol hydrochloride), in a dose-dependent manner. The dopamine D2/D3 receptor agonist 7-OH-DPAT ((+/-)-7-hydroxy-N,N-(di-n-propyl-2-aminotetralin)) at the lowest dose of 0.01 mg/kg increased both ethanol intake and preference. At higher doses (0.03-0.1 mg/kg) no significant effects were found. The dopamine D1 receptor antagonist SCH 23390 (R-(+)-7-chloro-2,3,4,5-tetrahydro-3-methyl-1-phenyl-1H-3-benzazepine-8- ol), dopamine D2/D3 receptor antagonist raclopride and 5-HT2/D2 receptor antagonist risperidone did not affect ethanol consumption, although all at high doses induced a significant decrease in water intake, indicating a non-specific decrease in consummatory behavior with these compounds.
2.Activation of adenosine A1 receptor modulates dopamine D1 receptor activity in stably cotransfected human embryonic kidney 293 cells.
Cao Y;Sun WC;Jin L;Xie KQ;Zhu XZ Eur J Pharmacol. 2006 Oct 24;548(1-3):29-35. Epub 2006 Aug 3.
The antagonistic interactions between adenosine A1 receptors and dopamine D1 receptors were studied in a human embryonic kidney 293 cell line stably cotransfected with human adenosine A1 receptor and dopamine D1 receptor cDNAs. In the cotransfected cells, but not in control cells only transfected with dopamine D1 receptors, adenosine A1 receptor agonist N6-cyclopentyladenosine (CPA, 10 microM) increased the Kd of dopamine D1 receptor antagonist [N-methyl-3H]R(+)-7-Chloro-8-hydroxy-3-methyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine ([3H]SCH23390) without affecting the Bmax. Moreover, CPA induced a concentration-dependent decrease in the affinity of dopamine D1 receptors for the agonist (+/-)-1-Phenyl-2,3,4,5-tetrahydro-(1H)-3-benzazepine-7,8-diol hydrochloride (SKF38393) and inhibited dopamine D1 receptor-mediated cyclic AMP response element recruitment. Furthermore, pertussis toxin treatment completely counteracted the effects of low concentrations of CPA but only partially counteracted the effects of high concentrations of CPA. These results suggest that adenosine A1 receptors antagonistically modulate dopamine D1 receptors at the level of receptor binding and the second messenger generation.
3.Endomorphins 1 and 2 induce amnesia via selective modulation of dopamine receptors in mice.
Ukai M;Lin HP Eur J Pharmacol. 2002 Jun 20;446(1-3):97-101.
The involvement of dopamine receptors in the amnesic effects of the endogenous micro-opioid receptor agonists endomorphins 1 and 2 was investigated by observing step-down type passive avoidance learning in mice. Although the dopamine D1 receptor agonist R(+)-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine-7,8-diol hydrochloride (R(+)-SKF38393) (0.05 and 0.1 mg/kg), the dopamine D1 receptor antagonist R(+)-7-chloro-8-hydroxy-3-methyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrochloride (R(+)-SCH23390) (2.5 and 5 microg/kg) or the dopamine D2 receptor agonist N-n-phenethyl-N-propylethyl-p-(3-hydroxyphenyl)-ethylamine (RU24213) (0.3 and 1 mg/kg) had no significant effects on the endomorphin-1 (10 microg)- or endomorphin-2 (10 microg)-induced decrease in step-down latency of passive avoidance learning, (-)-sulpiride (10 mg/kg), a dopamine D2 receptor antagonist, significantly reversed the decrease in step-down latency evoked by endomorphin-2 (10 microg), but not by endomorphin-1 (10 microg). Taken together, it is likely that stimulation of dopamine D2 receptors results in the endomorphin-2-but not endomorphin-1-induced impairment of passive avoidance learning.
