L-745870
- CAS No.: 158985-00-3
- Formula:C18H19ClN4
- Molecular Weight:326.82
IUPAC Name: 3-((4-(4-chlorophenyl)piperazin-1-yl)methyl)-1H-pyrrolo[2,3-b]pyridine
InChIKey: OGJGQVFWEPNYSB-UHFFFAOYSA-N
SMILES: ClC(C=C1)=CC=C1N(CC2)CCN2CC3=CNC4=NC=CC=C43
Biological Activity: L-745870 is a potent, selective, brain-penetrant and orally active dopamine D4 receptor antagonist with a Ki of 0.43 nM. L-745870 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].
