phenobarbital Phenobarbital: A barbituric acid derivative that acts as a nonselective central nervous system depressant. It potentiates GAMMA-AMINOBUTYRIC ACID action on GABA-A RECEPTORS, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.. phenobarbital : A member of the class of barbiturates, the structure of which is that of barbituric acid substituted at C-5 by ethyl and phenyl groups. | 7.36 | 2 | 0 | barbiturates | anticonvulsant; drug allergen; excitatory amino acid antagonist; sedative |
primidone Primidone: A barbiturate derivative that acts as a GABA modulator and anti-epileptic agent.

It is used as an anticonvulsant for treatment of various types of seizures. | 7.36 | 2 | 0 | pyrimidone | anticonvulsant; environmental contaminant; xenobiotic |
pentylenetetrazole Pentylenetetrazole: A pharmaceutical agent that displays activity as a central nervous system and respiratory stimulant. It is considered a non-competitive GAMMA-AMINOBUTYRIC ACID antagonist. Pentylenetetrazole has been used experimentally to study seizure phenomenon and to identify pharmaceuticals that may control seizure susceptibility.. pentetrazol : An organic heterobicyclic compound that is 1H-tetrazole in which the hydrogens at positions 1 and 5 are replaced by a pentane-1,5-diyl group. A central and respiratory stimulant, it was formerly used for the treatment of cough and other respiratory tract disorders, cardiovascular disorders including hypotension, and pruritis. | 2.38 | 2 | 0 | organic heterobicyclic compound; organonitrogen heterocyclic compound | |
methsuximide methsuximide: anticonvulsant effective in petit mal & psychomotor epilepsy; has a number of unpleasant & toxic side effects; minor descriptor (75-86); on-line & INDEX MEDICUS search SUCCINIMIDES (75-86); RN given refers to parent cpd without isomeric designation | 3.06 | 5 | 0 | organic molecular entity | |
bicuculline Bicuculline: An isoquinoline alkaloid obtained from Dicentra cucullaria and other plants. It is a competitive antagonist for GABA-A receptors.. bicuculline : A benzylisoquinoline alkaloid that is 6-methyl-5,6,7,8-tetrahydro[1,3]dioxolo[4,5-g]isoquinoline which is substituted at the 5-pro-S position by a (6R)-8-oxo-6,8-dihydrofuro[3,4-e][1,3]benzodioxol-6-yl group. A light-sensitive competitive antagonist of GABAA receptors. It was originally identified in 1932 in plant alkaloid extracts and has been isolated from Dicentra cucullaria, Adlumia fungosa, Fumariaceae, and several Corydalis species. | 1.97 | 1 | 0 | benzylisoquinoline alkaloid; isoquinoline alkaloid; isoquinolines | agrochemical; central nervous system stimulant; GABA-gated chloride channel antagonist; GABAA receptor antagonist; neurotoxin |
