Abstract
Abstract To identify potent dual 5-HT 2B and 5-HT 7 receptor antagonists, we synthesized a series of novel carbonyl guanidine derivatives and examined their structure–activity relationships. Among these compounds, N-(9-hydroxy-9H-fluorene-2-carbonyl) guanidine (10) had a good in vitro profile, that is, potent affinity for human 5-HT 2B and 5-HT 7 receptor subtypes (K i= 1.8 nM and K i= 17.6 nM, respectively) and high selectivity over 5-HT 2A, 5- ...
