• 개요

  A-77636 is a dopamine D₁ receptor agonist (K_i = 40 nM). It induces activity equal to or greater than dopamine in an adenylate cyclase assay of D₁ receptor activity in fish retina and rat caudate putamen (EC₅₀s = 7.4 and 1.1 nM, respectively) but does not show agonist activity at D₂ receptors expressed in MMQ cells when used at concentrations up to 10 μM. A-77636 (10 μM) induces desensitization of dopamine-stimulated cAMP accumulation and downregulation of D₁ receptors, reducing D₁ receptor expression by 79% in C-6 glioma cells expressing monkey D_1A receptors. In a marmoset model of Parkinson''s disease induced by MPTP, A-77636 (3 μmol/kg, s.c.) increases locomotor activity 5.3-fold and reduces disease severity. Subcutaneous administration of A-77636 elicits cortical acetylcholine release at a dose of 1 μmol/kg. It also elicits over a 230% increase in cortical and hippocampal acetylcholine release when administered at a dose of 4 μmol/kg, an effect that is blocked by the D₁ antagonist SCH 23390 .
