D1 glutamate modulator
D1-mediated glutamate modulator
- Theorized mechanism:
- ➔ D1 and NMDA receptors are co-localized on dendritic spines of cortical pyramidal neurons ◇ may form functional receptor complexes
- ➔ D1 activation triggers intracellular signaling cascades (e.g., cAMP/ Protein Kinase A pathways)
- ➔ these cascades increase phosphorylation of nearby NMDA receptor subunits
- ➔ phosphorylated NMDA receptors exhibit enhanced synaptic function
Drugs with this mechanism (1)
- Lumateperone — Low-metabolic-burden atypical for schizophrenia and bipolar depression; sedation dominates.
