amesergide inhibited the pressor response to serotonin in doses of 0.01-0.1 mg/kg i.v. The homochiral isopropyl tricyclic ergoline was more potent as a 5HT2 receptor antagonist than the epimeric (unnatural stereochemistry) analogue. Thus, the isopropyl moiety on the indole nitrogen is important for vascular 5HT2 receptor affinity in the rat. Most importantly, these data suggest that conformational rigidity
