Application

Amoxapine has been used as an antidepressant drug to test its effect on locomotion and egg release in response to gain-of-functional mutations in potassium (K+) channels (unc-58) of C. elegans. It has also been used as an antipsychotic drug to test its effect on the viability of glioblastoma cells.

Biochem/physiol Actions

Amoxapine, a structural analog of clozapine, is a human ether a-go-go (hERG) channel blocker. It is also an N-methylated metabolite of loxapine. It is a tricyclic antidepressant that inhibits the uptake of norepinephrine and blocks 5- hydroxytryptamine (HT2 ) serotonergic receptors.

Amoxapine is an N-demethylated dibenzoxazepine closely related in the neuroleptic loxapine. Its tricyclic structure appears to give it antidepressant properties resembling imipramine and amitriptyline. In uncontrolled trials it was shown to have antidepressant activity in usual doses up to 200

All currently available atypical antipsychotics have, at clinically relevant doses: i) high serotonin (5-HT)2 occupancy; ii) greater 5-HT2 than dopamine (D)2 occupancy; and iii) a higher incidence of extrapyramidal side effects when their D2 occupancy exceeds 80%. A review of

Journal of clinical psychopharmacology, 27(6), 575-581 (2007-11-16)
It has been proposed that the lack of extrapyramidal side effects of atypical antipsychotic drugs is caused by their fast dissociation or low affinity for the D2 receptor or their concomitant high affinity for other receptors, for example, 5HT2 and

Ion channels are known to be modulated by antidepressant drugs, but the molecular mechanisms are not known. We have shown that the antidepressant drug amoxapine suppresses rectifier outward K(+) (I(K)) currents in mouse cortical neurons. At a concentration of 10

A variety of antidepressants of different chemical classes were tested for their in vivo and in vitro activity at 5-HT1C receptors in the brain. Conventional tricyclic antidepressants (imipramine, desipramine, maprotiline, clomipramine, trimipramine, amitriptyline, nortriptyline, doxepin, amoxapine, oxaprotiline) and two atypical
