SUBSTITUTED 1-INDOLYLPROPYL-4-BENZYL-TETRAHYDROPYRIDINE DERIVATIVES

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-HT1-like receptors, being potent agonists of the human 5-HT1D alpha receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT1D alpha receptor subtype relative to the 5-HT1D 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-HT1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT1D receptor agonists.
