Bifemelane (INN) (Alnert, Celeport), or bifemelane hydrochloride (JAN), also known as 4-(O-benzylphenoxy)-N-methylbutylamine, is an antidepressant and cerebral activator that was widely used in the treatment of cerebral infarction patients with depressive symptoms in Japan, and in the treatment of senile dementia as well.[1][2] It also appears to be useful in the treatment of glaucoma.[3] It has been discontinued in Japan since 1998, when it was removed from the market reportedly for lack of effectiveness.[4]

Bifemelane acts as a monoamine oxidase inhibitor of both isoenzymes, with competitive (reversible) inhibition of MAO-A (Ki = 4.20 μM) (making it a reversible inhibitor of monoamine oxidase A (RIMA)) and non-competitive (irreversible) inhibition of MAO-B (Ki = 46.0 μM),[5][6][7] and also acts (weakly) as a norepinephrine reuptake inhibitor.[8] The drug has nootropic, neuroprotective, and antidepressant-like effects in animal models, and appears to enhance the cholinergic system in the brain.[9][10][11]

For example, bifemelane [4-(O-benzylphenoxy)-N-methylbutylamine) is one of the few molecules in which both activities, reversible inhibition of MAO-A (Naoi et al., 1988) and inhibition of noradrenaline uptake (Egawa et al., 1983), although weak (IC50 = 10-6-10-7 M), coexist.
