It is well established that, like glycine and D-alanine, D-serine potentiates glutamate neurotransmission via the N-methyl-D-aspartate (NMDA) receptor by selective stimulation of its strychnine-insensitive glycine site and acts as a co-agonist of the glutamate receptor.

The pharmacological properties of acetylcholine (ACh) receptors of cultured neurones from embryonic cockroach brains were studied using the whole-cell configuration of the patch-clamp technique.
The sequence of decreasing potency of the antagonists of the ACh response was: methyllycaconitine > alpha-bungarotoxin > mecamylamine > curare > strychnine > bicuculline > atropine > picrotoxin.

D-Serine binds to strychnine-insensitive glycine binding sites of the N-methyl-D-aspartate (NMDA) receptor complex, and enhances glutamate binding to the receptor complex.
A receptor autoradiographical analysis showed that the D-[3H] serine binding to the brain section was highest in the hippocampus, and the binding in the SAMP8 brains was lower than that of the SAMR1.

Glutamate receptors, such as the kainate receptor labeled by 3H-kainate, the N-methyl-D-aspartate (NMDA) receptor by 3H MK801, and the strychnine-insensitive glycine sites in the NMDA receptor by 3H-glycine, increased significantly in various cortical areas of schizophrenic brains.

Strychnine-insensitive glycine binding sites, an absolute requirement of the responses mediated by N-methyl-D-aspartate (NMDA) receptors, were measured in the postmortem brains of 13 chronic schizophrenics and 10 controls, using a radiolabeled receptor assay.

The effects of strychnine (STRY) on ion channels activated by N-methyl-D-aspartate (NMDA), kainate (KA), alpha-amino-3-hydroxy-5-methyl-4-isoxazolpropionate (AMPA) and quisqualate (QUIS) were studied using Xenopus oocytes, microinjected with mRNA from rats' brains.

Membrane currents induced by glycine (Iglys) were investigated in cholinergic neurons in primary culture, isolated from the septal region of fetal rat brains, by use of the whole cell voltage-clamp recording configuration.
Strychnine inhibited Igly in a dose-dependent and competitive manner; it took at most 1 min for this action to be attained to a steady level.

Strychnine and 7-chlorokynurenate failed to inhibit the binding at 10 microM.
The present findings indicate that the DCK-insensitive D-[3H] serine binding site could be a novel candidate for a target for endogenous D-serine in mammalian brains.

A correlation as observed between the pattern we obtained and that observed previously from strychnine binding studies.
We studied four different cDNAs encoding GABA transporters and three different cDNAs encoding glycine transporters in mouse and rat brains.

Neurochem Res. 2000 Dec;25(12):1587-601.


The binding of [3H] MUS alone, without enhancers may represent a ninth group of binding sites which is probably heterogeneous as indicated by the very low pseudo Hill coefficients for bicuculline and strychnine in displacing [3H] MUS without enhancer.
