Description
Maprotiline is a tetracyclic antidepressant that also exhibits sedative, anxiolytic, sympathomimetic, and anticancer activities. Maprotiline acts as an antagonist at norepinephrine transporters (NET), H1 histamine receptors, 5-HT2 receptors, α1-adrenergic receptors, muscarinic acetylcholine receptors (mAChRs), and L-type Ca2+ channels. Maprotiline induces caspase-mediated apoptosis in neuroblastoma cells, inhibiting cell viability in a JNK- and ERK-dependent manner. This compound also acts as a functional inhibitor of acid sphingomyelinase (FIASMA).
