实验参考方法

Cell experiment [1]:

Cell lines

Neonatal slices, juvenile slices

Preparation method

Soluble to 100 mM in sterile water. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

100 μM

Applications

In neonatal slices, a 5 Hz/3 min train of stimuli did not induce LTD of field EPSPs in the presence of 100 μM D-AP5. In juvenile slices, a 5 Hz/3 min train of stimuli did not induce LTD of field EPSPs in the presence of 100 μM D-AP5. In the presence of 100 μM D-AP5, voltage-clamping the cells at -80 mV during the induction protocol prevented the induction of mGluR-LTD.

Animal experiment [2,3]:

Animal models

Rats

Dosage form

0–50 mM

Application

In rats, D-AP5 (0–50 mM) via osmotic minipumps impaired spatial learning in a linear dose-dependent manner, highly correlated with its corresponding impairment of hippocampal LTP. No concentration of D-AP5 was observed to block LTP without affecting learning. Acute intrahippocampal infusion of radiolabelled D-AP5 revealed relatively restricted diffusion and was used to estimate whole-tissue hippocampal drug concentrations. Chronic i.c.v. infusions of D-AP5 caused a delay-dependent impairment of memory.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

产品描述

D-AP5 is a selective N-methyl-D-aspartate (NMDA) receptor antagonist (Kd = 1.4 μM) that competitively inhibits the glutamate binding site of NMDA receptors.[1] Whereas D-AP5 is the active (−)-stereoisomer, its (+)-isomer (L-AP5) demonstrates considerably less potent NMDA receptor antagonist activity.1 AP5 has been widely used to study the activity of NMDA receptors particularly in regard to researching synaptic plasticity, learning, and memory.[2]
