  Synthesis and anticonvulsant activity of enaminones

  摘要：

  A new series of novel enaminones has been synthesized from cyclic beta-dicarbonyl precursors which were condensed with morpholine, pyrrolidine, phenethylamine, hydrazines, substituted benzyl amines, and substituted anilines. These compounds were subsequently evaluated for anticonvulsant activity in a variety of anticonvulsant models by the National Institute of Neurological and Communicative Disorders and Stroke and in our laboratory. Several of these compounds exhibited potent anticonvulsant activity with a remarkable lack of neurotoxicity. The most active analog, methyl 4-[(p-chlorophenyl)amino]-6-methyl-2-oxo-cyclohex-3-en-1-oate (27), was protective in the maximal electroshock (MES) seizure test in the rat with an oral ED50 of 5.8 mg/kg with no toxicity noted at doses up to 380 mg/kg, thus providing a protective index (TD50/ED50) of > 65.5. A similar protective index for 27 was noted upon intraperitoneal (ip) administration in mice. The anticonvulsant effect of 27 occurred within 15 min of administration and the compound remained active beyond 4 h. Compound 27 was also active in the rat corneal kindled model. The application of Free-Wilson analysis to structure-activity correlation in this series is discussed.

  shown to be safer alternatives, the most notable was methyl 4-[(p-bromophenyl)amino]-6-methyl-2-oxocyclohex-3-en-1-oate, 13. Compound 13 had an ip ED50 of 4 mg/kg in the rat and a TD50 of 269 mg/kg, providing a protective index (TD50/ED50) of > 67. By variation in the ring size, additional aromatic substitutions and the synthesis of acyclic analogs, these newer compounds provide a more definitive insight

  该报告继续对4-[（对氯苯基）氨基] -6-甲基-2-氧代环己基-3-烯-1-酸酯1（ADD 196022）和甲基4-（苄基氨基）进行深入评估-6-甲基-2-氧代环己基-3-烯-1-酸酯，2个，两个有效的抗惊厥性烯胺酮。这些化合物采用杏仁核点燃模型进行评估。1和2都没有针对杏仁核点燃的癫痫发作的活性，进一步支持了角膜点燃的模型作为抗电击癫痫发作评估的确定工具，如先前报道。关于1的其他腹膜内（ip）数据显示，在100 mg / kg的24小时内有毒性。为了使毒性最小化，已经制备了几种活性类似物。在由抗癫痫药物开发（ADD）计划开发的特殊ip大鼠屏幕中，对这些新的类似物进行了评估，以防最大剂量10 mg / kg的电击惊厥（MES）和100 mg / kg的神经毒性。从该筛选中，显示出几种化合物是更安全的替代品，最引人注目的是4-[（（对-溴苯基）氨基] -6-甲基-2-氧代环己基-3-en-
