Abstract:
Phencyclidine (PCP) and other N-methyl-D-aspartate (NMDA) antagonists induce schizophrenia-like symptoms in humans. In rodents, PCP induces a syndrome of stereotypies and hyperactivity that is accompanied by stimulation of striatal dopamine release. Glycine and other NMDA agonists reverse PCP-induced behaviors in rodents and ameliorate PCP psychosis-like symptoms of schizophrenia in clinical trials. Glycine levels in vivo are regulated by the actions of glycine (GLYT1) transporters. The present study investigates effects of glycine and the prototypic glycine transport inhibitor glycyldodecylamide (GDA) on striatal dopamine release in vitro using a mouse striatal assay. Glycine and GDA significantly inhibit NMDA-induced striatal dopamine release, consistent with their ability to enhance local striatal inhibitory neurotransmission in vitro and to reverse PCP-induced hyperactivity in vivo.

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
