4F 4PP (oxalate) is a selective 5-HT2A antagonist with almost as high affinity (Ki= 5.3 nM) as ketanserin but with a much lower affinity for 5-HT2C sites (Ki= 620 nM)[1][2][3][4].

Name	(4-Fluorophenyl)[1-(4-phenylbutyl)-4-piperidinyl]methanone ethane dioate (1:1)

Target	5-HT2A Receptor:5.3 nM (Ki) 5-HT2C Receptor:620 nM (Ki)
In Vivo	4F 4PP (100 nM) reduces the lowest [D-ala2,N-me-phe4,gly.l5]-enkephalin (DAMGO) concentration and can produce a significant depression of evoked field potentials[1].
