TCN-201 is a novel, potent, non-competitive and selective antagonist of NMDA receptors containing the NR2A subunit with a pIC50 of 6.8. TCN 201 selectively blocks GluN2A-containing NMDARs in a GluN1 co-agonist dependent but non-competitive manner.
ln Vitro |
Compound 1, TCN 201, has a pIC50 of <4.3 and 6.8, respectively, making it more selective for GluN1/GluN2A NMDAR than GluN1/GluN2B NMDAR [1]. In oocytes, TCN 201 (10 μM) only modestly suppresses GluN1/GluN2B NMDAR-mediated currents [2]. In oocytes, TCN 201 (10-30 μM) exhibits a more powerful antagonistic effect on NMDAR-mediated responses, which is dependent on isoform and glycine [2]. In oocytes, NMDAR-mediated responses are not entirely blocked by TCN 201 (0.1-100 μM) [2]. In rat cortical neurons, TCN 201 (10 μM) antagonistic activity against NMDAR-mediated currents is inversely linked with its ifenprodil sensitivity [2]. In chick retina, cortical spreading depression (CSD) is inhibited by TCN 201 (1-9 μM) [3].

ln Vivo |
Rats with CSD exhibit an insufficient response to TCN-201 (10 mg/kg; intraperitoneal injection) regarding the blood oxygenation level-dependent (BOLD) response [4].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.50 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (4.50 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

TCN 201 antagonism of NMDAR-mediated responses is both subtype- and glycine-dependent and more potent than TCN 213. (ai), upper panel, molecular structure of TCN 201. Lower panel, TEVC currents recorded from an oocyte expressing GluN1/GluN2A NMDARs in response to application of glutamate (30 μM) and glycine (10 μM, left-hand trace; 30 μM, righthand trace). TCN 201 (10 μM) was applied as indicated and inhibited the glutamate/glycine-evoked response but the extent of the inhibition was dependent on the glycine concentration. (aii), upper panel, molecular structure of TCN 213. Lower panel, a series of similar TEVC current traces in equivalent conditions, but recorded in the presence of TCN 213 (10 μM). (aiii), bar graphs summarizing the mean data obtained from a series of experiments that investigated the glycine-dependency of TCN 201 (10 μM, n = 12; 30 μM, n = 8) and TCN 213 (10 μM, n = 11; 30 μM, n = 9) antagonism of steady-state responses at GluN1/GluN2A NMDARs. (b), a series of representative TEVC current traces illustrating similar experiments as in (a), but where the glycine concentration was fixed (30 μM) and glutamate was applied at either 3, 10 or 30 μM. The bar graph summarizes the mean data obtained from a series of experiments that investigated the glutamate-dependency of TCN 201 antagonism of steady-state responses at GluN1/GluN2A and NMDARs at 3 μM (n = 5), 10 μM (n = 6) and 30 μM (n = 6). (c), a series of representative TEVC current traces illustrating similar experiments to that shown in (a), but for recordings made from oocytes expressing GluN1/GluN2B NMDARs. Note here the modest inhibition produced by TCN 201. The bar graph summarizes the mean data obtained from a series of experiments that investigated the glycine-dependency of TCN 201 antagonism of steady-state responses at GluN1/GluN2B NMDARs at 3 μM (n = 6), 10 μM (n = 6) and 30 μM (n = 6).[2].

Inhibition curves for TCN 201 antagonism of GluN1/GluN2A NMDAR-mediated responses activated by co-agonists glycine or d-serine. (ai), TEVC trace recorded from an oocyte expressing GluN1/GluN2A NMDARs and voltage-clamped at −30 mV. The upper bar in this trace and in panels (aii), (ci) and (cii) indicates the duration of the bath application of glutamate/glycine, while the shaded bar in this panel (and in (ai), (ci) and (cii)) indicates the co-application TCN 201. Increasing concentrations of TCN 201 were applied, cumulatively, as indicated by the arrowheads. (aii), as in (ai), but currents are evoked using a higher concentration of glycine (30 μM). Note that TCN 201-mediated inhibition is less at this higher glycine concentration. (b), mean normalised inhibition curves for TCN 201 block of GluN1/GluN2A NMDAR-mediated currents evoked by glutamate (30 μM) and either 3 μM (n = 15; ■).[2]. Edman S, et, al.

Antagonism by TCN 201 of native NMDAR-mediated responses in rat cortical cultures. (a), left, example steady-state whole-cell currents activated by NMDA (50 μM) and glycine (3 μM) recorded from cortical pyramidal cells voltage-clamped at −70 mV from (ai), DIV 9–10 neurones, (aii), DIV 9–10 neurones transfected with GluN2A NMDAR subunits, and (aiii), DIV 15–18 neurones. To the right, traces illustrate the sensitivity of each of these NMDAR-mediated currents to the GluN2B-selective antagonist, ifenprodil (3 μM) and the subsequent sensitivity of the ifenprodil-insensitive component of this current to TCN 201 (10 μM). (b), left, bar graph summarizing the mean percentage ifenprodil block of NMDAR-mediated currents recorded from DIV 9–10 neurones (n = 7), GluN2A-transfected DIV 9–10 neurones (n = 6), and DIV 15–18 neurones (n = 9). Right, mean percentage TCN 201 block (expressed as a percentage of the original current magnitude) of NMDAR-mediated currents recorded from neurones in each of the three categories illustrated in (a). (c), plot illustrating the extent of ifenprodil and TCN 201 antagonism of NMDA-evoked currents from the same cell. Despite a wide range in the amount of block produced by either ifenprodil or TCN 201 (particularly for recordings from GluN2A-transfected and from neurones in older cultures) the data show a strong (negative) correlation (R2 = 0.91).[2].
