Irazepine

Irazepine (Ro 7-1986/1) is a benzodiazepine derivative containing isothiocyanate functional group.[1] It is a non-competitive benzodiazepine binding site antagonist.[2] Irazepine and other alkylating benzodiazepine, kenazepine, bind to brain benzodiazepine receptors in a non-competitive (covalent) fashion in vitro, and may exert a long-lasting anticonvulsant effect.[3]
