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.^[1] 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.
