were synthesized through acylation of the key aminonitrile derivatives 5a–c (Scheme 1) with the appropriate acid chlorides. Subsequent cyclization reaction yielded the target compounds (Schemes 2, 3). The chemical structure of the synthesized compounds was elucidated by spectral and elemental analyses. The synthesized compounds were evaluated for their ability to protect mice against PTZ-induced seizures
一系列新的二氮杂卓并[5,6- b ] pyrrolizines 7A - Ç和图8a - Ç和6-(2- oxopyrrolidino)-1 ħ -pyrrolizines 10A - Ç是通过氨基腈衍生物的关键的酰化合成5A - c ^(方案1 )和适当的酰氯。随后的环化反应产生目标化合物(方案2、3)。通过光谱和元素分析阐明了合成化合物的化学结构。评估了合成的化合物保护小鼠免受PTZ诱发的癫痫发作的能力,活性最高的化合物为10a –c,其中化合物10b与苯巴比妥相比具有67.9%的相对效能,而化合物10a在50 mg / kg的剂量下与苯巴比妥在20 mg / kg的剂量相比可提供所有化合物的最大保护百分比(60%)。
