3-([4-(4-CHLOROPHENYL)PIPERAZIN-1-YL]METHYL)-1H-PYRROLO(2,3-B)PYRIDINE HYDROCHLORIDE Chemical Properties,Usage,Production

Uses

L-745870 hydrochloride is a potent, selective, brain-penetrant and orally active dopamine D4 receptor antagonist with a Ki of 0.43 nM. L-745870 hydrochloride 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[1][2][3].

Biological Activity

Selective D4 dopamine receptor antagonist.

in vivo

L-745870 has good pharmacokinetic properties (20-60% oral bioavailability and plasma t1/2 2.1-2.8 hours) in both rat and monkey, and excellent brain penetration with high brain to plasma ratios in rat[1].
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].

IC 50

Human D4 Receptor: 4.3 nM (Ki); D2 Receptor: 960 nM (Ki); D3 Receptor: 2300 mM (Ki)
