A series of amides and sulfonamides, structurally related to DM235 (sunifiram) and MN19 (sapunifiram), derived by ring expansion or contraction, or by inversion of the exocyclic amide function, have been synthesized and tested for cognition-enhancing activity in the mouse passive-avoidance test. Some of the compounds display good antiamnesic and procognitive activity, with higher potency than piracetam
合成了一系列与DM235(sunifiram)和MN19(sapunifiram)结构相关的酰胺和磺酰胺,它们是通过环的扩张或收缩,或通过环外酰胺功能的反转而衍生的,并测试了其在小鼠被动中的认知增强活性-回避测试。一些化合物显示出良好的抗记忆和认知活性,具有比吡乙酰胺更高的效力,并且具有与母体化合物相似的效力。
