A series of N-methyl/acetyl, 5-(un)-substituted isatin-3-semicarbazones were screened for anticonvulsant and sedative-hypnotic activities. The results revealed that protection was obtained in all the screens i.e., MES, scPTZ, and scSTY. Compounds 2, 4, 6, 10 but not 1 and 3 showed low neurotoxicity when compared to clinically used drugs. Compounds 5, 7, 8 and 9 were completely non-toxic. Compound 6 showed good activity in the rat oral MES screen. Among all the compounds, 3 and 6 emerged as the most active compounds as indicated by the protection they exhibit in MES, scSTY, and scPTZ screens. All the compounds showed significant sedativehypnotic activity.

A diverse library of twenty-five 4-mono- and disubstituted semicarbazides was prepared in a one-pot two-step approach. The method includes formation of a carbamate from bis(2,2,2-trifluoroethyl)carbonate or 2,2,2-trifluoroethylchloroformate and a primary or secondary amine and subsequent interaction of the carbamate with hydrazine to result in a semicarbazide. The approach allowed to obtain 4-substituted semicarbazides on a large scale in good yield and high purity. This journal is
