Mechanism of action

PDE10A is predominantly expressed in medium spiny neurons of the striatum and is involved in dopamine and cAMP signaling. By inhibiting PDE10A, DMB-3115 enhances cAMP-mediated signaling, which may modulate dopaminergic and glutamatergic neurotransmission. This mechanism is hypothesized to provide therapeutic benefit in movement and psychiatric disorders.
