Abstract:
A class of 3-phenylimidazo[1,2-α]pyrimidine derivatives, substituted at the meta position of the phenyl ring by an optionally substituted aryl or heteroaryl group which is directly attached or bridged by an oxygen atom or a —NH— linkage, and further substituted on the phenyl ring by alkyl, trifluoromethyl, alkoxy or one or two halogen atoms, especially fluoro, are selective ligands for GABAA receptors, in particular having good affinity for the α2 and/or α3 and/or α5 subunit thereof, and are accordingly of benefit in the treatment and/or prevention of adverse conditions of the central nervous system, including anxiety, convulsions and cognitive disorders.
Abstract translation:一类3-苯基咪唑并[1,2-a]嘧啶衍生物,其在苯环的间位被被氧原子或-NH-键直接连接或桥连的任选取代的芳基或杂芳基取代, 并且在苯环上被烷基,三氟甲基,烷氧基或一个或两个卤原子,特别是氟取代,是GABA A A受体的选择性配体,特别是对α2和/或α3具有良好的亲和力 和/或其α5亚基,因此有益于治疗和/或预防中枢神经系统的不良状况,包括焦虑,抽搐和认知障碍。
Abstract:
A class of piperazinones, homopiperazinones and thione analogues thereof, substituted at the 1-position by an optionally substituted alkenyl, alkynyl, aryl-alkyl or heteroaryl-alkyl moiety, and linked at the 4-position via an alkylene spacer to a fused bicyclic heteroaromatic moiety, typically indolyl, 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 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, while eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT.sub.1D receptor agonists.
Abstract:
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 1-4 carbon atoms; Q represents a straight or branched alkylene chain containing from 1-6 carbon atoms; T represents nitrogen or CH; R.sup.1 represents aryl(C.sub.1-6)alkyl or heteroaryl(C.sub.1-6)alkyl, either of which groups may be optionally substituted; and R.sup.2 represents hydrogen or C.sub.1-6 alkyl 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. ##STR1##
