Dibenzocycloheptene (also known as dibenzosuberane and dibenzocycloheptadiene) is a tricyclic chemical compound featuring two benzene rings bound to a cycloheptene group. It is an occasional motif in synthetic organic chemistry. Various tricyclic antidepressants (TCAs) contain the dibenzocycloheptene moiety in their chemical structures, including amineptine, amitriptyline, amitriptylinoxide, butriptyline, demexiptiline, nortriptyline, noxiptiline, and protriptyline. Cyclobenzaprine, a skeletal muscle relaxant, also contains this functional group.
