Administration of the selective D1-dopamine receptor agonist 2,3,4,5-tetrahydro-7,8-dihydroxy-1-phenyl-1H-3-benzazepine (SKF-38393) to neonatal 6-hydroxydopamine-lesioned rats results in profound behavioral manifestations and induction of striatal c-fos-like immunoreactivity. The full D1-dopamine agonist l,(R,S)1-aminomethyl-3,4-dihydro-5,6-dihydroxy-3-phenyl-1H-2-benzopyran hydrochloride (A-68930), like SKF-38393, produced a dose-dependent, D1-selective increase in locomotor activity and striatal c-fos-like immunoreactivity. These results with A-68930 provide additional evidence that the specific behavioral and biochemical responses observed in neonatally lesioned rats after SKF-38393 administration are due to actions on D1-dopamine receptors, and indicate that A-68930 provides a new tool for investigating D1-dopamine receptor function.
