Tricyclic azepine derivatives as selective brain penetrant 5-HT6 receptor antagonists
摘要:
Starting from a benzazepine sulfonamide 5-HT(6) receptor antagonist lead with limited brain penetration, application of a strategy of conformational constraint and reduction of hydrogen bond donor count led to a novel series of tricyclic derivatives with high 5-HT(6) receptor affinity and excellent brain: blood ratios.

[Problem] Provided is a compound which is useful as an agent for treating or preventing 5-HT
2C
receptor-related diseases, particularly incontinence such as stress urinary incontinence, urge urinary incontinence, mixed urinary incontinence, and the like, sexual dysfunction such as erectile dysfunction syndrome and the like, obesity, and the like.
[Means for Solution] The present inventors have investigated compounds having a 5-HT
2C
receptor agonist activity, which is promising as an active ingredient of a pharmaceutical composition for treating or preventing incontinence such as stress urinary incontinence, urge urinary incontinence, mixed urinary incontinence, and the like, sexual dysfunction such as erectile dysfunction syndrome and the like, obesity, and the like, and have found that the benzazepine compounds of the present invention have an excellent 5-HT
2C
receptor agonist activity, thereby completing the present invention. That is, the benzazepine compounds of the present invention have a 5-HT
2C
receptor agonist activity and can be used as an agent for treating or preventing 5-HT
