Pharmacological study on some new 3-[(1-methylpyrrol-2-yl)-methyl]-4-substituted 4,5-dihydro-1H-1,2,4-triazol-5-ones.

3-[(1-Methylpyrrol-2-yl)methyl]-4-substituted 4,5-dihydro-1H-1,2,4-triazol-5-ones were obtained by the cyclization reaction of 1-[(1-methylpyrrol-2-yl)acetyl]-4-substituted semicarbazides in alkaline medium. The effects of the synthesized compounds of the central nervous system of mice were studied.
