1.
Seizures (Absence Seizure)
06/01/1991 - "
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.
"

These observations may provide one explanation for the long duration of the anticonvulsant activity of the parent compound U-54494A and further underscore the importance of voltage-dependent sodium channels in neuronal excitability, especially during seizures.
"
05/01/1992 - "
1. A pair of benzamide analogues containing a pyrrolidinyl or piperidinyl group was examined for their anticonvulsant activity against the electroshock-induced seizures in mice and the ability to block the voltage-gated Na channel in N1E-115 cells, in comparison with the prototype compound, U-54494A, (+/-)-cis-3,4-dichloro-N-methyl-N-[2-(1-pyrrolidinyl)-cyclohexyl]-ben zam ide , a potent anticonvulsant and a Na channel blocker.
"
01/01/1992 - "
Since U-54494A antagonizes amino acid-induced seizures (3), the interactions of this compound with glutamate are of interest.

"
03/01/1993 - "
U-54494A was less potent as an anticonvulsant than U-50488H in genetically epilepsy-prone rats and elicited a similar potency to that of U-50488H in DBA/2 mice when administered intracerebroventricularly or intraperitoneally.
"
01/01/1992 - "
The anticonvulsant activity of U-54494A was studied in a 4-aminopyridine (4-AP) epilepsy model using extracellular recordings in in vitro hippocampal slices.
