摘要:
The present invention relates to compounds of formula I: in which R1 is a linear group or a five membered heterocycle optionally fused to a phenyl ring, R2 is a 5-membered heterocycle, R3 is chosen from a range of substituents, m is 0–3 and n is 0 or 1; the compounds are generally inverse agonists at GABA-A receptors containing the alpha 5 subunit and so are useful in methods of enhancing cognition in subjects with diminished cognition in diseases such as Alzheimer's Disease.

摘要:
Substituted 1,2,4-Triazolo[3,4-A]phthalazine derivatives that are GABA Alpha 5 ligands are prepared from compounds represented by the formula: in which R1 is hydrogen, halogen, CF3, OCF3, CN or an optionally substituted C1-4alkyl, C2-4alkenyl, C2-4alkynyl, C1-4alkoxy, C2-4alkenyloxy or C2-4alkynyloxy group; R2 is hydrogen, halogen, CF3, OCF3, CN or an optionally substituted C1-4alkyl, C2-4alkenyl, C2-4alkynyl, C1-4alkoxy, C2-4alkenyloxy or C2-4alkynyloxy group; Z is an optionally substituted 5-membered or 6-membered heteroaromatic ring; and G is a leaving group.
摘要:
A class of substituted piperidine and tetrahydropyridine derivatives, linked through the 4-position thereof via an alkylene chain to a fused bicyclic heteroaromatic moiety such as indolyl, and further substituted at the 1-position by an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl-alkyl, 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.spsb..alpha. receptor subtype whilst processing at least a 10-fold selective affinity for the 5-HT.sub.1D.spsb..alpha. receptor subtype relative to the 5-HT.sub.1D.spsb..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 receptor agonists.
