In silico screening identified Ro-25-6981 (coded “MI-4”) as a dopamine transporter ligand. The NMDA receptor antagonist Ro-25-6981 also inhibits monoamine transporters (MATs). Ro-25-6981 exhibits rapid and sustained antidepressant-like effects in animal models. MAT virtual screening is a viable method to identify antidepressant lead compounds. Dual monoaminergic/glutamatergic agents are a novel strategy to treat depression.
