TCN 201 (compound 1) is selective for GluN1/GluN2A NMDAR over GluN1/GluN2B NMDAR, with pIC
50
s of 6.8 and <4.3, respectively.
TCN 201 (10 μM) produces only slight inhibition of GluN1/GluN2B NMDAR-mediated currents in oocytes.
TCN 201 (10-30 μM) antagonism of NMDAR-mediated responses is both subtype- and glycine-dependent and more potent than TCN 213 in oocytes.
TCN 201 (0.1-100 μM) does not produce complete block of NMDAR-mediated responses in oocytes.
TCN 201 (10 μM) antagonism of NMDAR-mediated currents shows a negative correlation with their ifenprodil sensitivity in rat cortical neurons.
TCN 201 (1-9 μM) suppresses cortical spreading depression (CSD) in chick retina.
