GtoPdb Ligand ID: 8424

Compound class: Synthetic organic
Comment: BF-1 is a selective antagonist of the 5-HT2B receptor, being investigated preclinically as an anti-migraine therapeutic [1]. Because this compound lacks high affinities for other monoamine receptors it should have fewer monoanimergic side effects than reported for previously used and withdrawn 5-HT2B antagonists such as methysergide and pizotifen. BF-1 is the result of structural modification of the chemical scaffold of methixene, a compound with high affinity for 5-HT2A, 2B, 2C, histamine H1, adrenaline α1A and muscarinic M2 receptors [1].
