L-745870 trihydrochloride is a highly potent and selective D4 dopamine receptor antagonist. L-745870 trihydrochloride exhibits moderate affinity for 5-HT2 receptors, sigma sites and α-adrenoceptors and shows weaker affinity for D2 and D3 receptors.

L-745870 trihydrochloride is a highly potent and selective D4 dopamine receptor antagonist. L-745870 trihydrochloride exhibits moderate affinity for 5-HT2 receptors, sigma sites and α-adrenoceptors and shows weaker affinity for D2 and D3 receptors.(In Vitro):L-745870 antagonizes the ability of D4 receptors to inhibit agonist-induced [35S]-GTPgS binding stimulation; blocks forskolin-stimulated adenocarcinoma in transfected human embryonic kidney (HEK293) and Chinese hamster ovary (CHO) cells Inhibition of pyridyl cyclase activity; blockade of dopamine-induced inhibition of Ca2+ currents in transfected GH4C1 pituitary cells; inhibition of D4 activation of cloned G protein-coupled inwardly rectifying K+ channels; and antagonism of dopamine-induced inhibition of transfected cells Stimulation of extracellular acidification .(In Vivo):L-745870 has favorable pharmacokinetic properties in both rats and monkeys, and shows excellent brain permeability and a high brain-to-plasma ratio in rats . L-745870 (10 mg/kg p.o.) at 30 mg/kg caused mild sedation and extrapyramidal motor symptoms, especially bradykinesia, following oral administration to squirrel monkeys. Lower doses of L-745870 had no apparent behavioral effects in monkeys .
