The present invention provide a compound having an orexin receptor antagonistic activity, which is expected to be useful as medicaments such as agents for the prophylaxis or treatment of sleep disorder, depression, anxiety disorder, panic disorder, schizophrenia, drug dependence, Alzheimer's disease and the like. The present invention relates to a compound represented by the formula (I): wherein each symbol is as defined in the specification, or a salt thereof.
Synthesis and application of [1,2,5]triazepane and [1,2,5]oxadiazepane as versatile structural units for drug discovery

scheme or table, p. 1001 - 1002 (2010/09/17)
Seven-membered heterocyclic [1,2,5]triazepane and [1,2,5]-oxadiazepane derivatives were synthesized as candidate structures for application in drug discovery in place of conventional piperazine or morpholine moieties, offering multiple sites for modification with functional groups. We first synthesized the Nprotected heterocycles, and then confirmed their utility by synthesizing analogues of the oxazolidinone antibacterial agent linezolid. The analogues exhibited potent in vitro and in vivo antibacterial activity. In particular, compound 10a exhibited good in vivo efficacy when administered intravenously in a murine model of systemic infection with methicillin-resistant Staphylococcus aureus SR3637. These seven-membered heterocycles are expected to be versatile structural units for drug discovery.

Page/Page column 233, (2009/01/24)
The invention provides a novel oxazolidinone derivative represented by the formula (I): wherein Ring A is optionally substituted or fused and represents (A-1) at least 7-membered monocyclic hetero ring containing at least three N atoms; (A-2) at least 6-membered monocyclic hetero ring containing at least two N atoms and at least one O atom; or (A-3) at least 7-membered monocyclic hetero ring containing at least two N atoms and at least one S atom; X1 is a single bond, -O-, -S-, -NR2-, -CO-, -CS-, - CONR3-, -NR4CO-, -SO2NR5-, and -NR6SO2- (wherein R2 - R6 are independently hydrogen or lower alkyl), or lower alkylene or lower alkenylene in which one of the preceding groups may intervene; Ring B is optionally substituted carbocycle or optionally substituted heterocycle; R1 is hydrogen, or an organic residue which is able to bind to the 5-position of oxazolidinone ring in oxazolidinone antimicrobial agent, and an antibacterial agent containing the same.
