Modulation of release of acetylcholine from the striatum by a proposed excitatory amino acid antagonist U-54494A: comparison with known antagonists, diazepam and phenytoin.[Pubmed:1348110]
Neuropharmacology. 1992 Feb;31(2):111-4.
The effect of (U-54494A) cis-3,4-dichloro-N-methyl-N-[2-(1-Pyrrolidinyl)- cyclohexyl] benzamide monohydrochloride, an excitatory amino acid antagonist, on N-methyl-D-aspartic acid (NMDA)- and K(+)-evoked release of [3H]acetylcholine [( 3H]ACh) from slices of striatum was investigated. For the purpose of comparison, MK 801, PCP, CGP 37849, CPP, phenytoin and diazepam were investigated under identical conditions. Both U-54494A and the excitatory amino acid antagonists blocked NMDA-evoked release of [3H]ACh but these compounds failed to inhibit K(+)-evoked release of this neurotransmitter. Phenytoin blocked both NMDA and K(+)-evoked release of [3H]ACh, whereas diazepam was ineffective under similar conditions. These observations indicate that excitatory amino acid antagonists, including U-54494A, may mediate their anticonvulsant effect by blocking the activity of NMDA receptors, diazepam by activating the benzodiazepine receptors and phenytoin by inhibiting the activity of various depolarizing agents.
In vitro depressant effects of U-54494A, an anticonvulsant related to kappa opioids, in the hippocampus.[Pubmed:1656303]
Neuropharmacology. 1991 Jun;30(6):637-42.
The effects of cis-3,4 dichloro-N-2-(1-pyrrolidinyl)cyclo-hexyl-benzamide (U-54494A), an anticonvulsant related to kappa opioids, were studied in vitro on the extracellular electrical activity of the CA1 region of slices of hippocampus in the rat. The effects of U-54494A were compared to those of the kappa opioid agonist trans-3,4 dichloro-N-2-(1-pyrrolidinyl)cyclo-hexyl benzeneacetamide methane sulphonate (U-50488H). Both U-54494A and U-50488H, in concentrations of 50 and 100 microM, respectively, reduced the magnitude of the orthodromically evoked CA1 population spikes after electrical stimulation of the stratum radiatum (100-200 microA, 70 microseconds, 0.1 Hz). Naltrexone (25 microM), or the selective kappa opiate receptor antagonist, 1-cyclopenthyl-5-(1,2,3,4,5,6-hexahydroxy-3,6,11-trimethyl-2 -6-methano-3- benzazocin)-3-pentatone methane sulphonate (WIN 44441-3) (25 microM), prevented the depressant activity of U-54494A (200 microM) on the CA1 population spikes. High calcium (+3mM) solutions prevented the depressant activity of increasing concentrations of both U-54494A and U-50488H on the amplitude of CA1 population spikes. Up to 200 microM, both drugs were ineffective in depressing the epileptiform bursting in CA1, due to 1 mM penicillin or to perfusion of the slice in absence of magnesium ions. The results demonstrate: (1) the inability of U-54494A to show antagonistic activity in two in vitro models of interictal epilepsy; (2) a depressant effect of U-54494A on basal synaptic transmission in the CA1 region of the hippocampus, which may be related to an influence on transneuronal calcium currents and which may be involved in the reported antagonism of ictal epileptic seizures by drugs.
U-54494A: a unique anticonvulsant related to kappa opioid agonists.[Pubmed:2824750]
J Pharmacol Exp Ther. 1987 Nov;243(2):542-7.
The benzamide U-54494A was compared to U-50488H (a structurally related kappa opioid agonist), phenytoin and phenobarbital in a variety of tests of anticonvulsant and sedative activities. In electroshock convulsion antagonism studies in mice and rats, U-54494A was generally similar to the standards in regard to milligrams of potency, threshold elevation, p.o. activity and duration of action. In contrast to phenytoin and phenobarbital, both U-54494A and U-50488H were effective antagonists of the convulsions induced by the excitatory amino acid agonists (kainic, N-methyl-aspartic and quisqualic acids) and the Ca++ channel agonist (Bay K 8644). They were not, however, effective antagonists of the gamma-aminobutyric acid-related convulsants (bicuculline and pentylenetetrazole), but all four blocked audiogenic convulsions in genetically epileptic mice. U-54494A in contrast to U-50488H lacks the kappa receptor-mediated sedative and analgesic activities but the anticonvulsant properties of both compounds are antagonized by high doses of naltrexone. Further investigations of the mechanism of action of these compounds revealed that both caused a dose-related suppression of post-tetanic repetitive discharge in cats soleus nerve-muscle preparations as measured by an abolition of the obligatory potentiation of soleus muscle contractile tension. On a biochemical level, both U-54494A and U-50488H attenuate the depolarization induced uptake of 45Ca++ into forebrain synaptosomes and block the enhancement of [3H]kainic acid binding induced by CaCl2. Together these results suggest that U-54494A is a unique and selective anticonvulsant agent acting by a Ca++-related mechanism possibly through a subclass of kappa receptors.
