  Amnesia-reversal activity of a series of 5-alkoxy-1-arylsulfonyl-2-pyrrolidinones

  摘要：

  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.

  γ-Lactam derivatives are widespread biologically active compounds, covering a large range of activities. Following our interest in both medicinal and green chemistries, we developed an original, cesium salts-mediated, scalable and solvent-free methodology to transform biosourced pyroglutamic acid and its derivatives to their N,N′-aminals, N,O,N,S-acetals and C5-substituted γ-lactams in good to excellent

  γ-内酰胺衍生物是广泛的生物活性化合物，涵盖了广泛的活性。遵循我们对药用和绿色化学的兴趣，我们开发了一种原始的铯盐介导的，可扩展且无溶剂的方法，以将生物来源的焦谷氨酸及其衍生物转化为N，N'-氨基苯胺，N，O，N，S -乙缩醛和C 5-取代的γ-内酰胺，收率良好至优异。该方案适用于多种底物，可作为潜在的新生物活性化合物与C 5-取代的γ-内酰胺衍生物进行反应。
