[Effects of a new minor tranquilizer, 10-chloro-3-methyl-1 1b-(2-chlorophenyl)-2,3,5,6,7,11b-hexahydrobenzo [6,7]-1,4-diazepino [5,4-b]-oxazol-6-one (CS-386), on the after-discharge and behavior induced by electrical stimulation of the amygdala in freely-moving cats (author's transl)].
Effects of a new minor tranquilizer, CS-386, on the after-discharge(AD) and behavior induced by amygdaloid electrical stimulation in freely-moving cats were compared with those of cloxazolam, oxazolam, diazepam, chlordiazepoxide, phenobarbital and chlorphromazine. Effects on change of the AD threshold and duration and on facial twitching, salivation and tonic-clonic convulsion were investigated. CS-386, cloxazolam and oxazolam inhibited amygdaloid AD. CS-386 had the most potent inhibitory effect. These drugs depressed all behavior described above. Diazepam had no effects on the AD threshold, but decreased the AD duration and inhibited the behavior. Chlordiazepoxide had no apparent effects on amygdaloid AD and on facial twitching. Salivation was inhibited with high doses of administration. Phenobarbital shortened the AD duration and at a high dose elevated the AD threshold. This drug also inhibited salivation, but inhibitory effects on other behavior required doses as high as 90 mg/kg. These results suggest that CS-386, cloxazolam and oxazolam are compounds belonging to a classification different from that of chlorpromazine. CS-386 in particular, is a more potent drug chlordiazepoxide, diazepam and phenobarbital and acts on the amygdala itself.
