Notes: BRL 44408 is an antagonist of α2A-adrenergic receptors (α2A-ARs; Ki = 8.56 nM for the recombinant human receptors).{45714} It is greater than 50-fold selective for α2A-ARs over α1-, α2B-, α2C-, β1-, and β2-ARs, as well as 19 other neurotransmitter receptors, transporters, and enzymes in a panel at 1 µM. BRL 44408 inhibits forskolin-stimulated cAMP accumulation with an IC50 value of 92.3 nM in CHO cells expressing the recombinant human α2A-AR. It increases norepinephrine and dopamine levels by 200 and 100%, respectively, in rat medial prefrontal cortex when administered at a dose of 10 mg/kg. BRL 44408 (10 and 30 mg/kg) decreases the time rats spend immobile in the forced swim test, indicating antidepressant-like activity, and reduces para-phenylquinone-induced abdominal stretching, indicating analgesic activity, in rats.
