  A series of 5-alkoxy-1-arylsulfonyl-2-pyrrolidinones were prepared by condensation of arylsulfonyl chlorides with 5-alkoxy-2-pyrrolidinones. Most compounds reversed electroconvulsive shock-induced amnesia in mice, showing the typical inverted U-shaped dose-response curve. The results for 58 compounds indicate that the potency is maximal when there is a 5-ethoxy group and progressively declines as the ether alkyl chain is either elongated or shortened. Substitution on the phenyl ring or its replacement with heterocyclic rings or its hydrogenation decreases the activity. The most promising compounds, with anti-amnesic properties superior in many respects (greater potency, greater efficacy and broader active dose-range) to those of piracetam and aniracetam were further evaluated for reversing scopolamine-induced amnesia and for their anti-hypoxic activity. 5-Ethoxy-1-phenylsulfonyl-2-pyrrolidinone (1) and 5-(1-methylethoxy)-1-/3-(trifluoromethyl) phenylsulfonyl/-2-pyrrolidinone (41) were selected for further evaluation because of their potent anti-amnesic and/or antihypoxic activity.

  A series of 5-alkoxy-1-arylcarbonyl-2-pyrrolidinones (1-27) were prepared by condensation of arylcarbonyl chlorides with 5-alkoxy-2 pyrrolidinones in the presence of butyl lithium in tetrahydrofuran. Alkylation of these intermediates with substituted benzyl bromides or chlorides, under solid/liquid phase-transfer conditions (KOH/Bu4NBr) in tetrahydrofuran, yielded 5-alkoxy-1-arylmethyl-2-pyrrolidinones (28-48). In the first series, the compounds with a 5-n-pentyloxy group had maximal ECS-induced amnesia reversing activity in mice, and in the second series, those with a 5-n-octyloxy group. In both series, substitutions on the phenyl ring had detrimental effects. The two most promising compounds 1-benzoyl-5-n-pentyloxy-2-pyrrolidinone (14) and 1-benzyl-5-n-octyloxy-2-pyrrolidinone (37) were more potent than piracetam and aniracetam and active over broader dose ranges: 50-200 and 50-400 mg/kg, po. Both compounds also reversed scopolamine-induced amnesia in mice, from 50 to 400 mg/kg, po (14) and from 100 to 400 mg/kg, po (37). Finally, 37 showed remarkable activity in protecting the mouse brain against chemically induced hypoxia, with a minimal effective dose of 50 mg/kg, ip, or 100 mg/kg, ip, in NaNO2- or KCN-induced hypoxia.
