| abstract |
A class of 3-substituted 3,7-diazabicyclo[3.3.0]octane derivatives, further substituted at the 7-position by an optionally substituted alkenyl, alkynyl, arylcarbonyl, aryl-alkyl or heteroaryl-alkyl moiety, are selective agonists of 5-HT 1 -like receptors, being potent agonists of the human 5-HT 1D α receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT 1D α receptor subtype relative to the 5-HT 1D β subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT 1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT 1D receptor agonists. |
