Chemical Name:8-[3-(4-Fluorophenoxy)propyl]-1-phenyl-1,3,8-triazaspir
o[4.5]-decanone
Biological Activity:
Selective 5-HT antagonist, which binds to 5-HT2 sites
as potently as spiperone but has lower affinity for 5-HT2C
receptors. Also a high affinity D2 receptor antagonist (Ki
= 3 nM). Lacks the disruptive effect of spiperone on animal behaviour.
