Altered glutamatergic synaptic transmission is among the key events defining the course of Alzheimer's disease (AD). mGlu2 receptors, a subtype of group II metabotropic glutamate receptors, regulate (as autoreceptors) fast synaptic transmission in the CNS via the controlled release of the excitatory amino acid glutamate. Since their pharmacological(More)
5,6-Dihydro-5-azacytidine (DHAC; NSC 264880) is an analogue of 5-azacytidine that does not possess the hydrolytically unstable 5,6-imino bond of the parent compound. Thus, unlike 5-azacytidine, DHAC is stable in aqueous solution and may be administered by prolonged i.v. infusion, potentially avoiding acute toxicities associated with bolus administration of(More)
A procedure is described for the rapid assessment of cataleptic activity (loss of righting, without head-drop and without eye closure) of phencyclidine-type drugs. Single- and cumulative-dosing procedures with phencyclidine and ketamine produced similar results. Pentobarbital produced loss of righting at doses which also induced head-drop and eye closure.(More)
