Isoform Comparison

Biological Activity

In Vitro:

Cell Line
Concentration Treated Time Description References
Mouse cerebral artery endothelial cells 10 µM 10 minutes D-AP5 significantly prevented the NMDA-induced increase in NMDAR sparklets, indicating that D-AP5 inhibits Ca2+ signaling by blocking the glutamate binding site of NMDAR. J Cereb Blood Flow Metab. 2022 Jan;42(1):145-161.
Cortical wedges 3.7 ± 0.32 µM (IC50) 15-20 minutes D-AP5 exhibited a selective reduction of NMDA-induced depolarization in cortical wedges with little or no effect on responses to quisqualate or kainate. Br J Pharmacol. 1988 Nov;95(3):957-65.
Mouse motor cortex slices 100 µM 25 minutes D-AP5 facilitated uniform DCS-LTD across the cortical thickness, abolishing DCS-LTP in deep layers Ann Neurol. 2020 Sep;88(3):489-502.

Administration Dosage Frequency Description References
C57BL/6 mice Cecal ligation puncture (CLP)-induced sepsis model Bilateral injection 1 μg/μl Single injection, lasting 30 minutes D-AP5 significantly prevented CNO-induced memory consolidation and improved cognitive dysfunction in septic mice. CNS Neurosci Ther. 2023 Jan;29(1):390-401
Mice C57bl6/J mice In vitro perfusion 10 mmol/L Single administration, lasting 10 minutes D-AP5 significantly blunted NMDA-induced dilation of PComA and parenchymal arterioles, indicating that D-AP5 attenuates vasodilation by inhibiting NMDAR in endothelial cells. J Cereb Blood Flow Metab. 2022 Jan;42(1):145-161.
Mice Mouse kainic acid seizure model Intraperitoneal injection 300μM Single dose, 60 minutes duration D-AP5 abolished DCS-LTP in deep layers, enhancing the uniformity of DCS-LTD Ann Neurol. 2020 Sep;88(3):489-502.
Rats Spinal and brainstem neurones Intravenous injection 50-100 mg/kg Single injection, effects lasted more than 6 hours D-AP5, administered intravenously, selectively reduced NMDA-induced excitation in rat spinal and brainstem neurones, with effects lasting more than 6 hours. Br J Pharmacol. 1988 Nov;95(3):957-65.
