BRL 44408 maleate is a selective antagonist of α2A-adrenoceptor with Ki values of 1.7 and 144.5 nM for α2A- and α2B-adrenoceptors, respectively. α2A-adrenoceptor is a G-protein coupled receptor. α2-adrenergic receptors include three subtypes: α2A, α2B and α2C, which play an important role in regulating neurotransmitter release from adrenergic neurons in the central nervous system and from sympathetic nerves. BRL 44408 maleate is a selective α2A-adrenoceptor antagonist. In rat brain, BRL 44408 inhibited the binding of 5-HTIA receptor radioligands 8-OH-DPAT and RX 821002 to cortical membranes with Ki values of 199 and 338 nM respectively, which suggested that BRL 44408 recognized 5-HT1A receptor . In wild type and monoamine oxidase-A knockout (MAO-A KO) mice, BRL 44408 (100 nM) inhibited the effect of dexmedetomidine, the α2 agonist. BRL 44408 (100 nM) increased evoked noradrenaline (NA) efflux in MAO-A KO mice. In wild type mice, BRL 44408 antagonized the agonist effect of dexmedetomidine with pKB value of 7.75, which inhibited locus coeruleus (LC) cell firing with EC50 value of 2.6 nM . In the forced swim test, BRL 44408 reduced immobility time. In schedule-induced polydipsia assay, BRL 44408 increased adjunctive water intake, which suggested that BRL 44408 exhibited antidepressant-like response. In a visceral pain model, BRL 44408 exhibited analgesic activity .
