Chemical Name: 1,3-Dihydro-5-[3-[4-(phenylmethyl)-1-2H-benzimidazol-2-one
Biological ActivityTCS 46b is an orally active, subtype-selective GluN1A/GluN2B (formally NR1A/NR2B) NMDA receptor antagonist (IC50 values are 5.3, 35000 and > 100000 nM for GluN1A/2B (NR1A/2B), GluN1A/2B (NR1A/2B) and GluN1A/2C (NR1A/2C) receptor subtypes respectively). Potentiates the effect of L-DOPA in 6-OHDA-lesioned rats following oral administration.
