NMDA receptor subunit 2A (NR2A) - No specific IC50/Ki/EC50 provided in this paper; the compound is described as an inhibitor of NR2A. [1]
|
|---|---|
| ln Vitro |
Inhibition of Src and NR2A with PP2 and NVP-AAM077 respectively not only down-regulated the levels of p-Src and p-NR2A, but also ameliorated hippocampal neurons apoptosis and long-term cognitive impairment after HIR
|
| ln Vivo |
In young C57BL/6 mice subjected to 70% hepatic ischemia reperfusion (HIR), pre-treatment with PEAQX (10 mg/kg i.p. daily for 3 days before surgery) significantly decreased the tyrosine phosphorylation of NR2A (p-NR2A) and Src (p-Src) in the hippocampus at 3 days after reperfusion compared to the HIR group (P < 0.05). [1]
PEAQX pre-treatment also decreased the interactions between Src and NR2A, as well as between Src and PSD95, as measured by immunoprecipitation at 3 days after HIR (P < 0.05). [1] PEAQX pre-treatment attenuated hippocampal neuron apoptosis (decreased apoptosis index by TUNEL staining) and reduced cleaved caspase-3 expression in the hippocampus at 3 days after HIR (P < 0.05). [1] In Morris water maze tests performed 1 month after HIR, PEAQX pre-treatment significantly increased the percentage of time spent in the target quadrant during probe trials compared to the HIR group (P < 0.05), indicating improvement of long-term cognitive impairment. [1] PEAQX pre-treatment did not affect serum levels of ALT, AST, TNF-α, IFN-γ, or IL-6 at 3 days after HIR, nor did it affect liver function or inflammatory cytokine levels at 1 month after HIR. [1] In sham-operated mice, PEAQX pre-treatment (10 mg/kg i.p. for 3 days) did not significantly alter the levels of p-Src, p-NR2A, c-Src, or NR2A in the hippocampus compared to vehicle-treated sham mice. [1] |
| Animal Protocol |
Animal model: 2-week-old C57BL/6 mice (weight 4-6 g) were subjected to 70% hepatic ischemia reperfusion (HIR) by clamping the left hepatic artery and portal vein for 1 hour, followed by reperfusion. Sham-operated mice underwent vessel isolation without clamping. PEAQX (NVP-AAM077) was dissolved in DMSO and diluted with sterile saline. Mice in the NVP group received intraperitoneal injections of PEAQX at a dose of 10 mg/kg once daily for 3 days before the HIR surgery. The sham(NVP) group received the same pre-treatment before sham operation. [1]
For assessment of short-term effects, mice were killed 3 days after reperfusion; for long-term cognitive assessment, Morris water maze tests were performed 1 month after HIR. [1] |

| Additional Infomation |
PEAQX (NVP-AAM077) is a selective antagonist of the NMDA receptor subunit 2A (NR2A). In this study, it was used to demonstrate that HIR-induced hippocampal injury and long-term cognitive impairment are mediated via the Src-PSD95-NR2A signaling pathway. Pre-treatment with PEAQX inhibited the tyrosine phosphorylation of NR2A and Src, reduced interactions among Src, PSD95 and NR2A, attenuated hippocampal neuron apoptosis, and improved long-term memory recall without affecting liver function or systemic inflammation. The results suggest that NR2A is a potential therapeutic target for preventing cognitive deficits after pediatric liver transplantation. [1]
