    Notes: Abstract: The amino acid D-serine (D-Ser), previously recognized as a pharmacological tool for potentiating neuronal activity mediated by the N-methyl-D-aspartate (NMDA) receptor complex. in vitro and in vivo, has been observed in several brain regions of the rat and mouse, most prominently in cortex. In addition to reconfirming the presence and distribution of D-Ser in rat brain, we have observed, for the first time, endogenous, free D-Ser in temporal cortex of normal human brains at a level of 2.18 ± 0.12 nmol/mg of protein, representing 15 ± 2% of the free L-Ser pool. The D-and L-Ser specific content and the D/L-Ser ratio obtained from temporal cortex of Parkinson and Alzheimer brains did not differ significantly from those of controls. However, at the levels ob served here, and considering its specificity and affinity for the NMDA-associated glycine receptor, endogenous D-Ser is a plausible NMDA receptor glycine site agonist.

    Notes: Abstract: Neurochemical interactions of tiletamine, a potent phencyclidine (PCP) receptor ligand, with the N-methyl-D-aspartate (NMDA)-coupled and -uncoupled PCP recognition sites were examined. Tiletamine potently displaced the binding of [3H]1-(2-thienyl)cyclohexylpiperidine with an IC50 of 79 nM without affecting σ-, glycine, glutamate, kainate, quisqualate, or dopamine (DA) receptors. Like other PCP ligands acting via the NMDA-coupled PCP recognition sites, tiletamine decreased basal, harmaline-, and D-serine-mediated increases in cyclic cGMP levels and induced stereotypy and ataxia. Tiletamine was nearly five times more potent than PCP at inhibiting the binding of 3-hydroxy[3H]PCP to its high-affinity NMDA-uncoupled PCP recognition sites. However, following parenteral administration, dizocilpine maleate (MK-801), ketamine, PCP, dexoxadrol, and 1-(2-thienyl)cyclohexylpiperidine HCl, but not tiletamine, increased rat pyriform cortical DA metabolism and/or release, a response modulated by the NMDA-uncoupled PCP recognition sites. Pretreatment with tiletamine did not attenuate the MK-801-induced increases in rat pyriform cortical DA metabolism, a result suggesting that tiletamine is not a partial agonist of the NMDA-uncoupled PCP recognition sites in this region. However, following intracerebroventricular administration (100–500 μg/rat), tiletamine increased pyriform cortical DA metabolism with a bell-shaped dose-response curve. These data indicate a differential interaction of tiletamine with the NMDA-coupled and -uncoupled PCP recognition sites. The paradoxical effects of tiletamine suggest that tiletamine might activate receptor(s) or neuronal pathways of unknown pharmacology.

    Notes: Abstract: The synthesis of nitric oxide by brain slices has been demonstrated in several laboratories. In addition, in vitro studies have demonstrated stimulation of nitric oxide synthesis by excitatory amino acid receptor agonists. These data have led to the hypothesis that this readily diffusible “intercellular messenger molecule”acts to generate a cascade effect by activating guanylate cyclase in several cell types and thereby augment levels of the second messenger cyclic GMP (cGMP). Therefore, we evaluated this hypothesis in vivo, by testing the actions of the nitric oxide synthase inhibitor N-monomethyl-L-arginine (NMMA) on elevations in level of mouse cerebellar cGMP generated by excitatory amino acid receptor agonists. The stimulatory effects of D-serine, quisqualate, and kainate were all found to be antagonized by this enzyme inhibitor. In addition, NMMA antagonized the increases in cerebellar cGMP level elicited by harmaline and pentylenetetrazole, pharmacological agents that augment endogenous excitatory amino acid transmission. Our data are, therefore, the first in vivo demonstration that nitric oxide is an important “messenger molecule”in the cerebellum, mediating the actions of kainate, quisqualate, and N-methyl-D-aspartate receptor agonists on guanylate cyclase. These data are consistent with previous in vitro findings with kainate and N-methyl-D-aspartate.

    Notes: Direct intracerebellar injections of TV-methyl-D-aspartate (NMDA) or D-serine elicited dose-dependent increases in cerebellar cyclic GMP levels, in vivo in the mouse. The actions of D-serine were antagonized by the competitive NMDA receptor antagonist 3-(2-carboxypiperazin-4-yl) propyl-1-phosphonic acid and by the phen-cyclidine receptor agonist MK-801, observations supporting actions at the NMDA-coupled glycine receptor. In addition, the actions of D-serine were antagonized by a partial agonist (D-cycloserine) and an antagonist (HA-966) of the NMDA-coupled glycine receptor. These data are all consistent with D-serine acting at the NMDA-coupled glycine receptor and represent the first demonstration of glycine receptor potentiation of ongoing NMDA-mediated neuronal activity in the CNS, rather than potentiation of exogenous NMDA.

    Notes: Abstract: A new method with the sensitivity and specificity required to measure regional levels of 3-methoxytyramine (3-MT) and normetanephrine (NMN) in the rat cortex is described. The method utilizes a liquid ion exchanger to isolate the parent amines, dopamine (DA) and norepinephrine (NE), along with their methylated metabolites. These samples are derivatized and analyzed by negative ion gas chro-matography-mass spectrometry. Using this method, we examined a number of drug actions on steady-state levels as well as pargyline-induced increases in 3-MT and NMN. In the prefrontal cortex, cingulate cortex, striatum, and olfactory tubercle, nomifensine was found to increase 3-MT steady-state levels and accumulation rates. Similar actions of this drug were observed in the cingulate and prefrontal cortices with NMN. In contrast, clonidine decreased cortical NMN levels and accumulation. A unique action was observed with haloperidol, in that both 3-MT levels and accumulation after pargyline were increased in the nigrostriatal and mesolimbic dopaminergic projections, whereas only the accumulation rates were accelerated in the mesocortical projections. In summary, our data indicate that this new assay is a useful approach for the in vivo evaluation of DA and NE release in cortical regions of the rat. This approach is unique in that no surgery, restraint, or anesthetic is required, thereby permitting more complicated experimental paradigms to be utilized.
