The present study was designed to investigate the efficacy of stimulation of alpha1-adrenoceptors and the strychnine insensitive glycine-B binding sites of the N-methyl-D-aspartate (NMDA) receptor complex to alleviate the age-related defect in water maze (WM) spatial (hidden platform) navigation.

The miniature excitatory postsynaptic currents (mEPSCs) were recorded in the presence of tetrodotoxin, bicuculline, and strychnine.

In addition, noradrenaline potentiated the strychnine-sensitive postsynaptic currents evoked in a slice preparation of sacral dorsal commissural nucleus.

Blockade of fast postsynaptic potentials with kynurenic acid plus bicuculline plus strychnine or with a low-Ca (2+)-high-Mg2+ medium failed to reduce their firing rate.

Monosynaptic excitatory postsynaptic currents (EPSCs) were evoked by electrical stimulation of the nucleus intercalatus in the presence of strychnine (5 microM) and bicuculline (10 microM).
A comparable degree of EPSC depression was also seen with the alpha2-adrenoceptor agonist clonidine (5 microM), and the alpha2A-agonist oxymetazoline (5 microM), while the alpha1-agonist phenylephrine (100 microM) caused only a 22% depression.

Excitatory postsynaptic currents (EPSCs) evoked by focal electrical stimulation were isolated by incubation with gabazine and strychnine, and inhibitory postsynaptic currents (IPSCs) were isolated with 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX).
Prazosin was used to block alpha1-adrenoceptors.

These neuron-driven activity patterns changed from random to rhythmic when the inhibitory synapses in the spinal cord were blocked by strychnine, bicuculline or both.
Such patterns were, however, modulated through muscarinic and alpha-adrenergic receptors.

J Pharmacol Exp Ther. 2000 Jan;292(1):215-27.


These compounds were shown to act in a use-dependent manner as antagonists of VSNaCs and to act as selective competitive antagonists at the strychnine-insensitive glycine recognition site of NMDA receptors.

The blood pressure responses to sodium nitroprusside were not modified by blockade of muscarinic receptors with methyl atropine (164 nmol, i.t.), or of nicotinic receptors with hexamethonium (211 nmol, i.t.), of alpha1-adrenoceptors with prazosin (3.1 nmol, i.t.), of alpha2-adrenoceptors with yohimbine (2.8 micromol/kg, i.v.), of 5-HT receptors with methysergide (5.1 micromol/kg, i.v.), or of glycine receptors with strychnine (65 nmol, i.t.).
