摘要:
A class of 1-[3-(1H-indol-3-yl)propyl]-4-benzyl-1,2,5,6-tetrahydropyridine derivatives, substituted at the 5-position of the indole nucleus by a 1,2,4-triazol-4-yl moiety, and on the methylene linkage of the benzyl moiety by an alkyl, alkoxy, or alkoxy-alkoxy substituent, are selective agonists of 5-HT.sub.1 -like receptors, being potent agonists of the human 5-HT.sub.1D.alpha. receptor subtype while possessing at least a 10-fold selective affinity for the 5HT.sub.1D.alpha. receptor subtype relative to the 5-HT.sub.1D.beta. 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.sub.1D.alpha. receptors is indicated, and are expected to have fewer undesirable cardiovascular and other side effects.
摘要:
A class of N-substituted piperazine, piperidine and tetrahydropyridine derivatives, linked by a fluoro-substituted alkylene chain to a fused bicyclic heteroaromatic moiety such as indolyl, and further substituted at the 4-position by an optionally substituted alkenyl, alkynyl, aryl-alkyl or heteroaryl-alkyl moiety, are selective agonists of 5-HT.sub.1 -like receptors, being potent agonists of the human 5-HT.sub.1D.alpha. receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT.sub.1D.alpha. receptor subtype relative to the 5-HT.sub.1D.beta. 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.sub.1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT.sub.1D recptor agonists.
