    The finding that ergotamine binds serotonin receptors in a less conserved extended binding pocket close to the extracellular entrance, in addition to the orthosteric site, allowed us to obtain 5-HT7R antagonist 6 endowed with high affinity (K i = 0.7 nM) and significant 5-HT1AR selectivity (ratio >1428). Compound 6 exhibits in vivo antidepressant-like effect (1 mg/kg, ip) mediated by the 5-HT7R, which reveals its interest as a putative research tool or pharmaceutical in depression disorders.
