structures as 5-hydroxy-5-trifluoromethylpyrazolines, a series of analogues was prepared via thermal condensation reactions between substituted acylhydrazones and trifluoromethyl 1,3-dicarbonyl arenes. Structure-activity relationship (SAR) studies showed that small lipophilic substituents at the 2- and 3-positions of the RHS and 2-, 3- and 4-postions of the LHS terminal benzene rings improved activity
The present invention is concerned with substituted imidazo[1,5-a][1,2,4]triazolo[1,5-d][1,4]benzodiazepine derivatives of the following formula
wherein the definition of substituents is described in the claims. This class of compounds shows high affinity and selectivity for GABA A α5 receptor binding sites and might be useful as a cognitive enhancer or for the treatment of cognitive disorders like Alzheimer's disease.
本发明涉及以下式的取代咪唑[1,5-a][1,2,4]三唑[1,5-d][1,4]苯二氮䓬啉衍生物,其中取代基的定义在权利要求中描述。这类化合物对GABA A α5受体结合位点表现出高亲和力和选择性,可能有助于作为认知增强剂或治疗认知障碍如阿尔茨海默病的药物。

The use of acyl hydrazines (hydrazides) as precursors for the stoichiometric generation of acylradicals is explored. Two classes of substrates are examined: unsubstituted acyl hydrazines and acyl hydrazines substituted with a leaving group (2-nitrobenzenesulfonyl or ‘nosyl’). Both types are successfully converted to acylradicals, and are then trapped by nitroxide radicals to give acyloxyamine products
