L-745870 trihydrochloride
Based on 3 publication(s) in Google Scholar
L-745870 trihydrochloride is a potent, selective, brain-penetrant and orally active dopamine D4 receptor antagonist with a Ki of 0.43 nM. L-745870 trihydrochloride shows weaker affinity for D2 (Ki of 960 nM) and D3 (Ki of 2300 nM) receptors, and exhibits moderate affinity for 5-HT2 receptors, sigma sites and α-adrenoceptors.

L-745870 is capable of antagonizing the ability of D4 receptors to inhibit agonist-induced stimulation of [35S]-GTPgS binding; blocking the inhibition of forskolin-stimulated adenylate cyclase activity in transfected human embryonic kidney (HEK293) and Chinese hamster ovary (CHO) cells; blocking dopamine-induced inhibition of Ca2+ currents in transfected GH4C1 pituitary cells; inhibiting D4 activation of cloned G protein-coupled inwardly rectifying K+ channels; and antagonizing dopamine-induced stimulation of extracellular acidification in transfected cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Following oral administration to squirrel monkeys, L745870 (10 mg/kg p.o.) induces mild sedation and extrapyramidal motor symptoms, notably bradykinesia, became apparent at 30 mg/kg. Lower doses of L-745870 has no observable behavioural effects in monkeys[1].
