Biological Activity

[Description]:

TCN 201 is a potent, selective and non-competitive antagonist of GluN1/GluN2A NMDAR. TCN 201 antagonism is dependent on the GluN1-agonist concentration. TCN 201 allows pharmacological identification of native GluN2A-containing NMDAR populations[1].

[Target]

NMDAR[1]

[In Vitro]

TCN 201 (10 μM) produces only slight inhibition of GluN1/GluN2B NMDAR-mediated currents in oocytes[1]. TCN 201 (10-30 μM) antagonism of NMDAR-mediated responses is both subtype- and glycine-dependent and more potent than TCN 213 in oocytes[1]. TCN 201 (0.1-100 μM) does not produce complete block of NMDAR-mediated responses in oocytes[1]. TCN 201 (10 μM) antagonism of NMDAR-mediated currents shows a negative correlation with their ifenprodil sensitivity in rat cortical neurons[1]. TCN 201 (1-9 μM) suppresses cortical spreading depression (CSD) in chick retina[2].

[In Vivo]

TCN-201 (10 mg/kg; i.p.) is ineffective in CSD g blood-oxygen level-dependent (BOLD) response in rats[3].
