The effect of alkylpyrazine derivatives on pentobarbital-induced sleeping time, picrotoxicin-induced convulsion and gamma-aminobutyric acid (GABA) levels in mouse brain were studied. The duration of pentobarbital-induced sleep in mice was dose-dependently increased by 2,5-dimethylpyrazine (DMP). The duration of pentobarbital-induced sleep was
