摘要:
A class of substituted imadazolo[2,1-a]phthalazine derivatives as ligands for GABAA receptors of formula I: which are partial or full inverse agonists of an α5 receptor subunit while being relatively free of activity at α1 and/or α2 and/or α3 receptor subunit binding sites are described herein; they are therefore of benefit as a medicament for enhancing cognition but with the reduction or elimination of proconvulsant activity.

摘要:
A class of 1-[3-(1H-indol-3-yl)propyl]-4-(2-phenylethyl)piperazine derivatives, substituted at the 5-position of the indole nucleus by a five-membered heteroaromatic moiety, on one or other of the ethylene carbon atoms of the phenethyl moiety by halogen, trifluoromethyl, alkyl, hydroxyalkyl or alkoxyalkyl, and optionally on the phenyl ring of the phenethyl moiety by halogen, trifluoromethyl, alkoxy or an oxazolidinone group and optionally by one or two further substituents, 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 receptor agonists.

摘要:
A class of substituted azetidine, pyrrolidine and piperidine derivatives 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 receptor agonists.

摘要:
6-Substituted-4-hydroxycinnolin-3-yl carboxylic acids and esters thereof, processes for their preparation, and pharmaceutical compositions comprising any one of these compounds. A representative compound is ethyl 6-glycylamino-4-hydroxycinnolin-3-yl carboxylate hydrochloride. The compounds are active as inhibitors of effects following the combination of reagin-like antibodies and their antigens.
摘要:
Compounds of formula (I), or a salt or prodrug thereof, wherein Z represents an optionally substituted five-membered heteroaromatic ring selected from furan, thiophene, pyrrole, oxazole, thiazole, isoxazole, isothiazole, imidazole, pyrazole, oxadiazole, thiadiazole, triazole and tetrazole; E represents a chemical bond or a straight or branched alkylene chain containing from 1 to 4 carbon atoms; Q represents a straight or branched alkylene chain containing from 1 to 6 carbon atoms, optionally substituted in any position by a hydroxy group; T represents nitrogen or CH; U represents nitrogen or C--R.sup.2 ; V represents oxygen, sulphur or N--R.sup.3 ; --F--G-- represents --CH2--N--, --CH2--CH-- or --CH.dbd.C--; R.sup.1 represents C.sub.3-6 alkenyl, C.sub.3-6 alkynyl, aryl(C.sub.1-6)alkyl or heteroaryl(C.sub.1-6)alkyl, any of which groups may be optionally substituted; and R.sup.2 and R.sup.3 independently represent hydrogen or C.sub.1-6 alkyl are selective agonists of 5-HT1D receptors, being potent agonists of the human 5-HT1Dalpha receptor subtype, while possessing at least a 10-fold selective affinity for the 5-HT1Dalpha receptor subtype, relative to the 5-HT1Dbeta 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, while eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT1D receptor agonists.
